My little application is written in reactjs, on a page it will update title / description based on the real object that user selected like this photo. The new title and description are display correctly but when sharing on fb, the values are not loaded correctly (the value is from old html templated) - go to facebook and paste the url or use fb debugger the values are from static html page.
Have anyone had this issue and have "fixed" it ?
Thanks for any recommendation !
Facebook ignores JavaScript, so dynamic OG tags are not possible. You can solve this with Server Side Rendering or https://prerender.io/, for example.
You can pass as parameter in url (abc.com?title=awesome&desc=flower), and in og tags use that parameter to make dynamic.
I have previously created a web app, and now I would like to integrate it with OnsenUI to enable my app to be used on all mobile devices as well as the web.
I am using a splitter in a toolbar which will be the header of all pages, and it will redirect the user to other pages when they click an item in it. Clicking the home item successfully redirects to the home page (index, which is already loaded correctly). However, clicking any of the other items in the splitter redirects me to the requested page, but shows the content of the file in text format instead of actually rendering the page. It looks like the following, except it's all jumbled together with no spaces:
searchForTrainer.jade:
//-ons-template(id='searchForTrainer.jade')
ons-page(ng-controller='SearchController' ng-init='showme = false; getAllTrainers();')
ons-toolbar
.left
ons-toolbar-button(ng-click='mySplitter.left.open()')
ons-icon(icon='md-menu')
.center
| Search Trainer
// ***** I cut off the rest of the file for simplicity
// ***** I should still be able to see the toolbar if the page loads correctly

here is the splitter load page function I am using in my angular file:
this.load = function(page) { console.log("The page is: " + page);
mySplitter.content.load(page)
.then(function() {
mySplitter.left.close();
});
};
Has anyone successfully built an Onsen app using Jade?
UPDATE
When I leave the code in html instead of jade, everything works correctly. When I convert it back to jade it shows up as text again.
UPDATE 2
Using Solution 1 from the selected answer, I realized and solved my problem with the guidance from the selected answer on my other post:
Answer
By the looks of it you seem to be using Jade on the server side.
To solve the problem I see a couple possible solutions.
Solution 1:
Make sure that whatever Onsen UI is receiving is pure HTML. You're free to use Jade, but as it stands Onsen does not have Jade bundled inside, so there is no way for it to support it out of the box. However as long as Onsen sees only html it should be fine.
The reason why the ons-template(id='index.jade') works initially is actually because when you serve the page you are actually serving actual html, so when onsen starts the contents of that template are actually pure html.
In searchForTrainer.jade it seems that you are giving it raw jade, which it does not know how to handle. You can handle this on the server side, making sure that the request for the searchForTrainer returns html. Returning jade.renderFile('searchForTrainer.jade') from the server instead of the jade file itself should solve the issue.
Solution 2:
As you noticed as long the contents are inside the initial page everything will be fine. So you could just put all your ons-templates inside the initial page.
If you want to retain your current file structure you can just do
include searchForTrainer.jade
while having an ons-template tag in the file itself. That way in the end the result will be a page with the template already converted into html.
Solution 3:
The final option is to give the raw jade files, but help Onsen understand Jade, so that it can use them properly. To do that you need to include jade.js and modify Onsen UI so that it uses it.
However since Onsen does not currently provide an official API for switching template engines whatever hack we use now might break in the future. It's possible that in the near future a feature like that may be implemented, but in order to do it now we need to wrap some of onsen's internal functions.
Here's a simple example to do it.
module.run(function($onsen) {
var old = $onsen.normalizePageHTML;
ons._internal.normalizePageHTML = $onsen.normalizePageHTML = function(html) {
return old(jade.render(html, {}));
};
});
And here's also a working Demo showing this solution in action.
Note: that demo actually checks for a comment // jade at the beginning just to be safe.
Which solution to choose?
Solution 1 - I think this makes most sense as it retains a clear separation of concerns. If you want to change the templating engine it should be handled only in one place. Onsen does not need to know what you're using on the server as long as it gets what it wants.
Solution 2 - Not the best way to solve the problem, but it may be the easiest to use if you just want things to work. One minus is that with it you would load all the templates at the beginning, which may not be very good.
Solution 3 - While this solution can work I would suggest avoiding it as handling jade on the frontend would result in poor performance. It's could be an option if you actually decide not to rely on the server.
I am having 2 problems in below code.

Validation is not working when i try to run the application as main page - applicationpage.aspx page. but when i use any html page for main page validation is working fine.
when i click on edit at list.html page. it is redirecting me to edit.html page. that is ok. but data is not coming for the employee for whom i want to edit. data only coming when i change some text in any input control. i don't why ?
Thanks
1 now this is done as i have to provide there ng-form tag instead of form in child page. which is edit.html –
Extjs prefers your app to be a single page app, but I'd still like to be able to do things like refresh my page and keep my current location in the app, and enter a url to get directly to a particular point in the app. Is there a solution for this?
Yes, I do the same in my app. You can use the Ext JS history mechanism to do so. Have a look at this example from Sencha.
You can listen to the history change event like this
Ext.History.on('change', function(token) {
// you navigate-to-target code goes here, e.g. change the viewport content
}
You can then initiate navigation by setting the browser hash to some navigation target
document.location.hash = yourNavigationToken;
This gives you also the ability to use deep-linking and forward/backward navigation with the browser buttons.
You need to init the history:
// The only requirement for this to work is that you must have a hidden field and
// an iframe available in the page with ids corresponding to Ext.History.fieldId
// and Ext.History.iframeId. See history.html for an example.
Ext.History.init();
and add an iframe and a hidden input field to your page, like in the example:
<form id="history-form" class="x-hide-display">
<input type="hidden" id="x-history-field" />
<iframe id="x-history-frame"></iframe>
</form>
I am doing pagination in cakephp. By default there is a list in
"$this->Paginator->numbers" but i want some changes in pagination design so i want all pages in dropdwon and current page is selected in dropdown. I successfully get the dropdown by writing the following code but the problem is that when i click on the page it wil not change
thanks in advance
`
< select>
echo $this->Paginator->numbers(array('tag'=>'option'));
</select>
`
You have to bind event onChange to your select element with JS. It should redirect you to selected page. You can see how to construct jump url in cake's documentation. You can also use this solution but notice it was written for cake 1.x and will need some changes.
