I am a newbie at the MEAN stack. I have a full app working and have searched extensively on how to solve the following problem but I'm realizing that I don't know how to "ask" the question to be sent to the proper resource.
I have a marketplace. In the dashboard, a user can enter details about their product (a boat) and it is sent to the DB. In my marketplace, I'm retrieving all of the boats from the DB and theyre styled and listed on the page.
I want a user to click on one of the tiles components that I have created with an ng-list (boat) and be sent to a new page with a fully-expanded view of that specific boat. (larger pictures, expanded details, etc.) basically all the details about the product that won't fit in the minimalistic tile component in the marketplace.
How do I pass data about that specific boat that the user clicks on and be sent to a new page? Is this an ng-directive? an API/route thing?
I just am unsure how to reference the specific boat from the list i'm retrieving and have the user sent to a new details page. Any direction or resources that will teach me to solve this problem?
In general, use ng-repeat to display a list of products and ng-click to handle clicks.
<a ng-repeat="product in productList" ng-click="goto($index)">
<h2> {{product.title}}</h2>
<img ng-src="{{product.picture}}">
<p>{{product.description}}</p>
</a>
JS
$scope.goto = function(index) {
$location(productList[index].location);
});
Use a router such as ngRoute or ui-route to intercept the new location and load the appropriate template and controller.

My web-app is written by AngularJs+ ui-router.
The web-app contains many forms (the number of forms are vary, depending on the application the user is applying). Each form has a ui-route state, so our users can go to each form and fill the information.
Before users submit the application we would like to implement a "summary/review" state(page) that contains all the forms the user filled, so users can review (and print) all the information from one page. Is there any way I can use the same form template (templateUrl) for the summary page?
I was thinking to use ng-include and programmatically(ng-repeat) list out all the selected forms, but it seems doesn't work.
PS: my form template might use different controller..
OK, I figured this out.
For ng-include: we need to use
<ng-include src="'formPath'"></ng-include>
For putting the ng-include in a repeater:
<div ng-repeat="f in vm.thisApp.RequiredForms">
<ng-include src="f.FormPath"></ng-include>
</div>
I hope this helps anyone who needs the answer.
The issue is best illustrated in the plunker - http://plnkr.co/edit/9DYQ3rlmiMK9bdtjyYOA.
Basically, I am trying to create a meta form rendering engine using angular with the help of directives that handle interpretation of data runtime and render the fields accordingly.
Please let me know if you have any ideas why the dyn-ng-repeat directive is not rendering the three URL fields under the user object as expected in the code below -
<div dyn-ng-repeat="item in {{field.model}}">
<div ng-repeat="field in field.children" ng-include src="'field.html'">/div>
</div>
Thanks.
EDIT:
Hi guys, I have created a full Plunker here - http://plnkr.co/edit/cFreJZbluy3w4R9PZUCD?p=preview that should have all the code necessary but not working.
Basically, there is a hierarchy of objects. Social Networks have URLS and a list of Friends. The code is supposed to display three social networks and each should have two friends listed under them. The button 'Add Network' should add another social network to the list and the button 'Remove Network' should remove the respective network associated with it along with all its children. Similarly, 'Add Friend' should add a new friend object under that Social Network and 'Remove Friend' should remove the respective friend from under that network.
It's a bit complex, but if you look at it for a couple of minutes, you'll get the idea of what I'm trying to do here. It's dynamic DOM based on the data elements that are bound two way.
Thanks.
I have one search page with some search criteria. From that page I going to some other page and clicking browser back button means the page was refreshing. Actually I page should not be refresh instead on refreshing the page should display with some result with out refreshing.
Kindly give me suggestions.
From you question i understand that you need navigate to some other page without refreshing the page as like google.
But its not done using cache. There are function called pushState() and onpopstate() to make this.
How it will work?
With the function pushState(), we can able to change the url of a page without refreshing the page. And the previous url will automatically added to the history. So we need implement a single page to load the content of the page using ajax based on the url.
The function onpopstate() will be triggered when a url is changed using pushState().
Example:
http://html5.gingerhost.com/
The above page uses the above function. That page consist of 4 links (Home, Seattle, New York, London). When we click on those link a new url will be loaded without refreshing the page.
<title></title>
<ul id="menu" class="clearfix">
<li class="current">Home</li>
<li>Seattle</li>
<li>New York</li>
<li>London</li>
</ul>
<article>
<h1></h1>
<div id="image"></div>
<div id="articletext"></div>
<div class="clear"></div>
</article>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.0/jquery.min.js"></script>
<script>
// THIS IS WHERE THE MAGIC HAPPENS
$(function() {
//Capture the click on the links
$('#menu a').click(function(e) {
href = $(this).attr("href");
// Call a function to load the content based on the url
loadContent(href);
// HISTORY.PUSHSTATE add the url to the history
history.pushState('', 'New URL: '+href, href);
e.preventDefault();
});
// THIS EVENT MAKES SURE THAT THE BACK/FORWARD BUTTONS WORK AS WELL
window.onpopstate = function(event) {
console.log("pathname: "+location.pathname);
// Load the content on clicking back or forward using its url
loadContent(location.pathname);
};
});
function loadContent(url){
// USES JQUERY TO LOAD THE CONTENT PROVIDED BY content.php
$.getJSON("content.php", {cid: url, format: 'json'}, function(json) {
// output provider by content.php like {"title":"Seattle - Part of a demo for #ProSEO","h1":"Seattle","article #articletext":"<p>Seattle is the northernmost major city in the contiguous United States, and the largest city in the Pacific Northwest and the state of Washington. It is a major seaport situated on a narrow isthmus between Puget Sound (an arm of the Pacific Ocean) and Lake Washington, about 114 miles (183 km) south of the Canada - United States border, and it is named after Chief Sealth \"Seattle\", of the Duwamish and Suquamish native tribes. Seattle is the center of the Seattle-Tacoma-Bellevue metropolitan statistical area--the 15th largest metropolitan area in the United States, and the largest in the northwestern United States.<\/p><p>Seattle is the county seat of King County and is the major economic, cultural and educational center in the region. The 2010 census found that Seattle is home to 608,660 residents within a metropolitan area of some 3.4 million inhabitants.

// THIS LOOP PUTS ALL THE CONTENT INTO THE RIGHT PLACES(values will be set)
$.each(json, function(key, value){
$(key).html(value);
});
});
}
</script>
As like above you can able to render the content and provide a json response and pass it to the jquery and you can able to achieve that.
Some suggestions:
Use session to store search parameters, when user back to search page check if session exist. If exist use that parameters to find data again or load cached query results.
Better options, change form request type from POST to GET method. So when you submit search form, your url looks like:
http://myhost.com/search?q=my+term¶m1=zzz¶m2=¶m3=
Use this url parameters to find data again. This option allow you to share search criteria with other users.
Create the search values to create a unique key e.g. with md5. Then store the result with this key to your caching system ( file, memcached whatever).
So if a user should run the same search again fetch the result directly from cache without bothering the db.
It could look like this:
$sCacheKey = md5(json_encode($this->data));
$result = Cache::read($sCacheKey, 'short');
if ($result === false) {
$result = $this->YourModel->find(conditions etc....);
Cache::write($sCacheKey, $li, 'short');
}
Or do you want to cache your complete rendered page?
I am testing out the mirror api and so far I have a sample app running nicely.
The issue I am having is that I added a menu item for the action 'SHARE' but when I try to share the timeline card created by my app to Google+ it posts an empty Google+ post. The only text in the Google+ post is #throughglass. The contents of the timeline card is some simple html (see below) which renders find on glass. I also set the speakable text which works great with the 'READ_ALOUD' menu action. What gives on the 'SHARE' action, am I missing something?
Link to Google+ post
Timeline Item html:
<article class="auto-paginate">
<section>
<p class="text-auto-size">
Hello Word.
</p>
</section>
</article>
Each application is free to choose what, from the shared timeline item, it will use as part of the share command. The Google+ Glassware appears to use the text field only when sharing a textual item and ignores the html field.
(This makes some sense. Google+ can't display the HTML formatting, so it chooses to go with the text that it knows should be good.)
When you're writing Glassware, you should make sure both the text and html (and speakableText, for that matter) fields contain the correct representation of your item.
I'm trying to figure out how to link an html picture element back to the database entry that was originally used to generate the picture link.
I am using Meteor:
- I have a database that contains photosets data from Flickr API
- In the HTML, I have a handlebar "each" script that iterates through each photoset in the database and then uses this info to generate the html for the photoset cover picture links.
- When the html renders, the photoset cover pictures are downloaded from Flickr and displayed to the screen.
I would like to be able to click on the photoset cover picture and then automatically generate the links to the pictures in the photoset. But I don't understand how to dynamically link the html picture elements back to their respective database entries that were originally used for generating the picture links. I need to be able to find the original database entries so that I can load the info needed for generation of subsequent links.
As a newb to all of this I'm not really sure where to start looking or what to try. I've wondered about creating an object with custom key pairs to 'memorise' the identity of each photoset picture. Is this the way to go, or is there an easier way that I am overlooking?
Thanks.
Say you have your pictures being put out this way:
Template.mytemplate.helpers({
picture:function() {
return pictures.find()
}
});
You can also do this instead, which is pretty much the same thing:
Template.mytemplate.picture = function() {
return pictures.find();
}
With the html
<template name="pictures">
{{#each picture}}
<img src="{{src}}" class="pictureselector"/>
{{/each}}
</template>
You can use events which can get data from that particular picture document/record
Template.mytemplate.events({
'click .pictureselector':function(event,template) {
console.log(this._id); //Should give you the `_id` of the picture that was clicked
}
});
this is the data context of the element that was clicked & generate the link you want using the data inside this.
Be careful if you use something with a callback inside the click like Meteor.call, you will have to relay the message down via var self = this otherwise the context of this would become the one of Meteor.call
