I wrote a jQuery function in my EmberJS application but it is not loading.
The jQuery function changes a graph dynamically based on input values.
My code can be viewed using this Developer tool: Application URL

This is a pretty newbie question. However, in EmberJS, I've found that both of the methods work for linking to the blog page in my application.
<p>{{#link-to 'posts'}} See my blog{{/link-to}}</p>

Is it better to use {{link-to}} in EmberJS? How come?
The difference is that the {{link-to}} component will navigate to the specified route within the current running Ember application, while <a href="posts"> will do a new browser request to that location and re-start your Ember app at that route. You should use {{link-to}} since you'll be using the Ember internals to navigate within your single-page application and it will be a smoother user experience.
While they both can work, watch your browser closely and you'll see the anchor tag will give you a page refresh and re-launch your Ember app (though in the right location). Using a {{link-to}} will feel faster since Ember is presenting the new page via javascript rather than restarting after a page refresh. It's the difference between navigating within a single-page application, and jumping into a SPA from an external page.
While Ember does render an anchor tag in place of the {{link-to}} at run-time, it interjects to stop the default anchor tag behaviour. The docs explain it like so:
By default the {{link-to}} component prevents the default browser
action by calling preventDefault() as this sort of action bubbling is
normally handled internally and we do not want to take the browser to
a new URL (for example).
(from https://emberjs.com/api/classes/Ember.Templates.helpers.html#toc_allowing-default-action)
Also, with the {{link-to}} component you can pass a model directly into the route. This is a bit more advanced, but the Ember guides have some good examples.

I am testing a web application where the HTML is built by JavaScript/jQuery/AJAX using the JSON respones from REST calls.
This being a very huge js file (require.js is also used), I'm finding it very hard to find the function which is sanitizing the JSON responses. Backtracking from the AJAX call or from the functions listed in https://code.google.com/archive/p/domxsswiki/wikis/jQuery.wiki is taking me nowhere.
Is there any way I can track the execution of the JS step by step, before it creates the HTML source for me?
Any add-on which could help? I have tried the 'visual event' add-on from Chrome, but it is not completely helpful as it displays only the JavaScript function attached to an event for DOM elements.
I've done some example apps in Ember, and now I'm ready for using it in existing application. Its traditional web application (request-response, full reload and some ajax loaded content, no rest/api things)
So lets assume I've few page (urls) like
1 abc.com/home.php
2. abc.com/support.php ,
3. abc.com/support.php?call=meeting
and so on..
so is it possible to use just one url with ember app and rest leave as such untill its ready?
PS: I did try for support.php as this.route("support",{path:"/support.php"}) and have SupportController and support.hbs template but its not working. I'm not sure how to put it in jsfiddle.
Thanks
Include your ember app only on the page that needs it, so only on abc.com/support.php
As far as ember can see, when you go to abc.com/support.php you are on the index page (of the ember app), and you will need to use the index.hbs tempate.
How can we render visualforce page by using ember.js framework?
How can I bind server(apex controller) data with model so when
template will load then data should be display on page? My server
data is coming in json hierarchical form.
How can we assign more than one json variable to template.
As an answer to 1. check out https://github.com/mickle00/salesforce-emberjs. This repository contains a barebones ember.js app in a visualforce page.
When you build your Ember App in this visualforce page you can use javascript remoting to call your controller methods.
By the way, you'll probably get a better answer on the salesforce stackexchange
I am doing a project in Django and i want to have some google maps displayed in my site. So, i installed django-easy-maps and successfully used it in a sample template. So, i am ready with my maps.
The interface i want to implement is this
http://i49.tinypic.com/sowm74.png
I want to display the maps where the Hellow World! container is and with different links on the sidebar i want to refresh the map being displayed on user click without reloading the page.
I did some researching and it seems Ajax is the solution...
Can anybody tell me how i might achieve this (with or without Ajax ) ?
Sorry for sounding like a noob but i am fairly new to this.
The basic steps are:
Create a view for the Google Maps section to the right. This view does not return a full HTML page but only the HTML for that section (which contains your Google Maps map).
When the user clicks on a link on the left, use JavaScript to perform an ajax call to request that page. In short this means: attach an event handler to the onclick event of those links and in code you can perform an ajax call .Many people use a JavaScript library for this purpose, such as jQuery (which has $.ajax()).
You can then use JavaScript to put the received HTML inside the container on the right (using $.html()).
