Why ajax works only for homepage? - cakephp

I have baked new project. My simple ajax function inserted to ..\templates\Pages\home.php:
function loadDoc() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
document.getElementById("demo").innerHTML =
this.responseText;
}
};
xhttp.open("GET", "myTest.txt", true);
xhttp.send();
}
My myTest.txt is in ..\webroot\ location.
Why this works for homepage, but not for any other created site in project? For all sites except homepage cakePHP can not find my text file. I have tried various locations for this file.

You should use "/myTest.txt" for the URL to open. Without the / on the front, it is interpreted as a relative URL, so if you're at something like /page/2, then it will look for /page/myTest.txt, which doesn't exist.

Take HTTP_ROOT as constant in bootstrap.php holding the base url(site name without sub path).
define the <base href="<?= HTTP_ROOT;?>" /> on the layout->head section. this will help to hit the site without sub-path on ajax request.
you can take a further constant eg-"siteURL" in javascript inline code on the layout's <head> OR a hidden input holding the base path.
Use the constant if you need.
siteURL+(if any further dir under webroot)+'myTest.txt'

location.path() not redirecting to page

In node this is how I define my details route (render as jade and send).
app.get('/details', function(req, res){
jade.renderFile('details.jade', function(err, html){
if(err){
console.log(err);
}
res.send(html);
});
});
In jade with 'blah' is clicked then calls navigateToPath function with params.
a(ng-click="navigateToPath(date_obj_key, part)") blah
In angular, this function should go to this path. The url path changes in the browser but it does not REDIRECT to the page. Help (yes I am injecting the location service)
$scope.navigateToPath = function(date, part){
var path = '/details?date='+date+'&part_type='+part;
$location.path('/details').replace(); //also tried $location.url(path)
$scope.apply(); //also tried $scope.$apply and $rootScope.$apply as func
console.log($location.path());
}
I am using Fire Fox developer tools(F12) and put a break point on where I used $window.location in my project and looked at the values in $window.location and this what it shows:
It seems like this would work. for both a location in the same folder or sub-folder as well as going to a completely different web site.
$window.location = $window.location.origin + path
or
$window.location = <whatever website you want to go to>
In my case I was just using the $window.location to call a rest service to download a file that the user selected from a ui-grid while still staying on the same page. and this may have worked for me because my scenario is a bit different then what yours is I think. so all I had to do was
$window.location = "../../services" + "<path to my rest service>" + $scope.shortCode + "/" + $scope.wireInstSelectedRow.entity.fileName;
#shapiro I am not sure why this does not work
$location.path('/details').replace();
I tried the same thing originally in my project and based on the documentation: https://docs.angularjs.org/api/ng/service/$location It seems like that would work and what its supposed to be used for but what I noticed is it would put a '#' character in the url before it put the path I wanted it to take which was preventing it from going to that page. Anyhow for me it seems like as long as you are going to an html page that is in the same folder or sub-folder just doing
$window.location = <the path you want to go to>;
is a good solution... at least it did the trick for me. Hope this helps.

Implementing google custom search in angularjs

I am trying to implement google custom search in an angular js website.
When I click on the search button it does not display me anything, but the url is updated to the url.
I have followed the steps mentioned in the documentation by google.
I am not sure what I am doing wrong?
My search bar is located on the home page as -
<gcse:searchbox-only enableAutoComplete="true" resultsUrl="#/searchresult" lr="lang_en" queryParameterName="search"></gcse:searchbox-only>
my search result has -
<gcse:searchresults-only lr="lang_en"></gcse:searchresults-only>
Any input is much appreciated.
Thanks,
You may have more than one problem happening at the same time...
1. Query Parameter mismatch
Your searchresults-only does not match the queryParameterName specified on gcse:searchbox-only.
Index.html
<gcse:searchresults-only queryParameterName="search"></gcse:searchresults-only>
Search.html
<gcse:searchresults-only queryParameterName="search"></gcse:searchresults-only>
2. Angular.js is blocking the flow of Google CSE
Under normal circumstances, Google Search Element will trigger an HTTP GET with the search parameter. However, since you are dealing with a one-page application, you may not see the query parameter. If that suspicion is true when you target resultsUrl="#/searchresult", then you have two options:
Force a HTTP GET on resultsUrl="http://YOURWEBSITE/searchresult". You may have to match routes, or something along those lines in order to catch the REST request (Ember.js is really easy to do so, but I haven't done in Angular.js yet.)
Use JQuery alongside Angular.js to get the input from the user on Index.html and manually trigger a search on search.html. How would you do it? For the index.html you would do something like below and for the results you would implement something like I answered in another post.
Index.html
<div>GSC SEARCH BUTTON HOOK: <strong><div id="search_button_hook">NOT ACTIVATED.</div></strong></div>
<div>GSC SEARCH TEXT: <strong><div id="search_text_hook"></div></strong></div>
<gcse:search ></gcse:search>
Index.js
//Hook a callback into the rendered Google Search. From my understanding, this is possible because the outermost rendered div has id of "___gcse_0".
window.__gcse = {
callback: googleCSELoaded
};
//When it renders, their initial customized function cseLoaded() is triggered which adds more hooks. I added comments to what each one does:
function googleCSELoaded() {
$(".gsc-search-button").click(function() {
$("#search_button_hook").text('HOOK ACTIVATED');
});
$("#gsc-i-id1").keydown(function(e) {
if (e.which == 13) {
$("#enter_keyboard_hook").text('HOOK ACTIVATED');
}
else{
$("#search_text_hook").text($("#gsc-i-id1").val());
}
});
}
(function() {
var cx = '001386805071419863133:cb1vfab8b4y';
var gcse = document.createElement('script');
gcse.type = 'text/javascript';
gcse.async = true;
gcse.src = 'https://cse.google.com/cse.js?cx=' + cx;
var s = document.getElementsByTagName('script')[0];
s.parentNode.insertBefore(gcse, s);
})();
I have a live version of the index.html code, but I don't make promises that will be permanently live since it is hosted in my NDSU FTP.

Dynamic content Single Page Application SEO

I am new to SEO and just want to get the idea about how it works for Single Page Application with dynamic content.
In my case, I have a single page application (powered by AngularJS, using router to show different state) that provides some location-based search functionalities, similar to Zillow, Redfin, or Yelp. On mt site, user can type in a location name, and the site will return some results based on the location.
I am trying to figure out a way to make it work well with Google. For example, if I type in "Apartment San Francisco" in Google, the results will be:
And when user click on these links, the sites will display the correct result. I am thinking about having similar SEO like these for my site.
The question is, the page content is purely depending on user's query. User can search by city name, state name, zip code, etc, to show different results, and it's not possible to put them all into sitemap. How google can crawl the content for these kind of dynamic page results?
I don't have experience with SEO and not sure how to do it for my site. Please share some experience or pointers to help me get started. Thanks a lot!
===========
Follow up question:
I saw Googlebot can now run Javascript. I want to understand a bit more of this. When a specific url of my SPA app is opened, it will do some network query (XHR request) for a few seconds and then the page content will be displayed. In this case, will GoogleBot wait for the http response?
I saw some tutorial says we need to prepare static html specifically for Search Engines. If I only want to deal with Google, does it mean I don't have to serve static html anymore because Google can run Javascript?
Thanks again.
If a search engine should come across your JavaScript application then we have the permission to redirect the search engine to another URL that serves the fully rendered version of the page.

You can either use this tool by Thomas Davis available on github
SEOSERVER
Or
you can use the code below which does the same job as above this code is also available here
Implementation using Phantom.js
We can setup a node.js server that given a URL, it will fully render the page content. Then we will redirect bots to this server to retrieve the correct content.
We will need to install node.js and phantom.js onto a box. Then start up this server below. There are two files, one which is the web server and the other is a phantomjs script that renders the page.
// web.js
// Express is our web server that can handle request
var express = require('express');
var app = express();
var getContent = function(url, callback) {
var content = '';
// Here we spawn a phantom.js process, the first element of the
// array is our phantomjs script and the second element is our url
var phantom = require('child_process').spawn('phantomjs',['phantom-server.js', url]);
phantom.stdout.setEncoding('utf8');
// Our phantom.js script is simply logging the output and
// we access it here through stdout
phantom.stdout.on('data', function(data) {
content += data.toString();
});
phantom.on('exit', function(code) {
if (code !== 0) {
console.log('We have an error');
} else {
// once our phantom.js script exits, let's call out call back
// which outputs the contents to the page
callback(content);
}
});
};
var respond = function (req, res) {
// Because we use [P] in htaccess we have access to this header
url = 'http://' + req.headers['x-forwarded-host'] + req.params[0];
getContent(url, function (content) {
res.send(content);
});
}
app.get(/(.*)/, respond);
app.listen(3000);
The script below is phantom-server.js and will be in charge of fully rendering the content. We don't return the content until the page is fully rendered. We hook into the resources listener to do this.
var page = require('webpage').create();
var system = require('system');
var lastReceived = new Date().getTime();
var requestCount = 0;
var responseCount = 0;
var requestIds = [];
var startTime = new Date().getTime();
page.onResourceReceived = function (response) {
if(requestIds.indexOf(response.id) !== -1) {
lastReceived = new Date().getTime();
responseCount++;
requestIds[requestIds.indexOf(response.id)] = null;
}
};
page.onResourceRequested = function (request) {
if(requestIds.indexOf(request.id) === -1) {
requestIds.push(request.id);
requestCount++;
}
};
// Open the page
page.open(system.args[1], function () {});
var checkComplete = function () {
// We don't allow it to take longer than 5 seconds but
// don't return until all requests are finished
if((new Date().getTime() - lastReceived > 300 && requestCount === responseCount) || new Date().getTime() - startTime > 5000) {
clearInterval(checkCompleteInterval);
console.log(page.content);
phantom.exit();
}
}
// Let us check to see if the page is finished rendering
var checkCompleteInterval = setInterval(checkComplete, 1);
Once we have this server up and running we just redirect bots to the server in our client's web server configuration.
Redirecting bots
If you are using apache we can edit out .htaccess such that Google requests are proxied to our middle man phantom.js server.
RewriteEngine on
RewriteCond %{QUERY_STRING} ^_escaped_fragment_=(.*)$
RewriteRule (.*) http://webserver:3000/%1? [P]
We could also include other RewriteCond, such as user agent to redirect other search engines we wish to be indexed on.
Though Google won't use _escaped_fragment_ unless we tell it to by either including a meta tag; <meta name="fragment" content="!">or using #! URLs in our links.
You will most likely have to use both.
This has been tested with Google Webmasters fetch tool. Make sure you include #! on your URLs when using the fetch tool.

What URL to be used in viewer.js in Box API?

I would like to know what is the URL used in Viewer.js.
<div class="viewer" style="height: 100%"></div>
<script type="text/javascript">
var viewer = Crocodoc.createViewer('.viewer', { url: 'url/to/crocodoc/assets/' });
viewer.load();
</script>
I have uploaded document using view-api.box.com/1/documents
This give me document ID.
Then I created a session using view-api.box.com/1/sessions
This give me Session ID.
I wrote viewer.js at my server and gave it URL view-api.box.com/view/{session} but this didn’t work. I am sure in am wrong here.
I would like to know how will I get URL which need to be put in Viewer.js
To use viewer.js currently, you must download the converted assets to your own server to host them. There isn't a URL to point to on the View API itself. This is outlined in the README, but the basic steps for using viewer.js are:
Download the documents assets to your server with GET /documents/content.zip
Unzip the assets on your server (let's call the unzipped directory /yourmachine/assets
Initialize viewer.js by pointing it to /yourmachine/assets i.e.
var viewer = Crocodoc.createViewer('.viewer', {
url: '/yourmachine/assets'
});
Edit: You can also use sessions with viewer.js. The URL format is:
https://view-api.box.com/1/sessions/THE_SESSION_ID/assets
Good answer Seanrose, however I was still struggling because your example didn't work. I tried
var viewer = Crocodoc.createViewer('.viewer', {
// Replace this URL with the path to the converted document assets
url: '/var/www/wordpress/wp-content/themes/themename/crocodoc/assets'
});
No combination of "//" in the beginning and "/" at the end worked
So I moved everything to a subdirectory of the index.html and .js and .css files and this worked...
var viewer = Crocodoc.createViewer('.viewer', {
// Replace this URL with the path to the converted document assets
url: 'assets'
});
Finally!! I realised it really was a URL, not a file location that was needed and experimented a bit more. The final (correct) answer is:
var viewer = Crocodoc.createViewer('.viewer', {
// Replace this URL with the path to the converted document assets
url: '//yourdomain.com/subdirectories/assets'
});
So a relative reference works (but not recommended in WordPress), however a full URL minus the HTTP: is fine, so long as "//" is at the front and not "/", and there should be no "/" at the end.

Angular js way to download file and show loading screen using the $resource

I am using Angular js to show loading screen. It works for all the REST services call except REST service to download the file. I understand why it is not working because for download I am not making any service call using $resource; instead of that I am using normal approach to download the file therefore Angular js code doesn't have any control on start/finish the service request. I tried to use $resource to hit this REST service however I am getting the data from this service and in this case loading screen was working fine however not sure how to use this data to display to user to download in angular way. Following are required details. Please help.
Approach 1 using iframe approach:
/*Download file */
scope.downloadFile = function (fileId) {
//Show loading screen. (Somehow it is not working)
scope.loadingProjectFiles=true;
var fileDownloadURL = "/api/files/" + fileId + "/download";
downloadURL(fileDownloadURL);
//Hide loading screen
scope.loadingProjectFiles=false;
};
var $idown; // Keep it outside of the function, so it's initialized once.
var downloadURL = function (url) {
if ($idown) {
$idown.attr('src', url);
} else {
$idown = $('<iframe>', { id: 'idown', src: url }).hide().appendTo('body');
}
};
Approach 2 using $resource (Not sure how to display data on screen to download)
/*Download file */
scope.downloadFile = function (fileId) {
//Show loading screen (Here loading screen works).
scope.loadingProjectFiles=true;
//File download object
var fileDownloadObj = new DownloadFile();
//Make server call to create new File
fileDownloadObj.$get({ fileid: fileid }, function (response) {
//Q? How to use the response data to display on UI as download popup
//Hide loading screen
scope.loadingProjectFiles=false;
});
};
This is the correct pattern with the $resource service:
scope.downloadFile = function (fileId) {
//Show loading screen (Here loading screen works).
scope.loadingProjectFiles=true;
var FileResource = $resource('/api/files/:idParam', {idParam:'#id'});
//Make server call to retrieve a file
var yourFile = FileResource.$get({ id: fileId }, function () {
//Now (inside this callback) the response data is loaded inside the yourFile variable
//I know it's an ugly pattern but that's what $resource is about...
DoSomethingWithYourFile(yourFile);
//Hide loading screen
scope.loadingProjectFiles=false;
});
};
I agree with you that this is a weird pattern and is different of other APIs where the downloaded data is assigned to a parameter in a callback function, hence your confusion.
Pay attention to the names and the cases of the parameters, and look that there're two mappings involved here, one between the caller to the $resource object and the object itself, and another between this object and the url that it contructs for downloading the actual data.
Here are some idea's for the second approach, you could present the user with a link after the download has happened:
With a "data url". Probably not a good idea for large files.
With a URL like "filesystem:mydownload.zip" You'd first have to save the file with the filesystem API. You can find some inspiration on html5rocks
