The code is all about calling a function in the onChange event of a select box.
<select id="locationLevelId" onChange="abc();">
Now,I need the equivalent code using javascript dom and also using jquery ie calling the function abc() for the onChange event.
JavaScript
document.getElementById('locationLevelId').onchange = abc;
JQuery
$('#locationLevelId').on('change',abc);

I have an anchor element <a> and an image inside it. Both of them have JavaScript methods.
<img src="" onclick="someOtherMethod()">
Which Javascript function will be executed first, the function in the image onclick or the function in the link href?
The function inside the onclick attribute of the image will execute first.
You can observe this happening in this jsFiddle demo.

I am making a http request that returns a url to an image. I would like to display the image in my html page. Is there a way to do this? I idea of what I want to do is (this doesn't work but..) img src={{result.imageurl}}
Yes, you have to use ng-src="{{result.imageurl}}"
See http://docs.angularjs.org/api/ng.directive:ngSrc

Before I had chosen.js I could find the specific option, remove it, and then create a new option instead, giving it the same value as it the deleted option has...
Now it doesn't work... the select itself changes - but it is hidden when using chosen.js...
And what was supposed to be a simple task is not simple at all!
Can someone help me?
Thanks!
Use $("#your_field").trigger("chosen:updated"); after updating select options.
Just as is written in reference: http://harvesthq.github.io/chosen/#change-update-events

Let us consider we have a function for validating all fields in the form. If I am changing the input of one particular field, the only field that has been changed should be validated but not other fields.
If you are using jQuery, you can use .bind() function to trigger on the change of the input box.
$("element").bind('change', function({}));
