The interaction between a parent element and an iframe, combining mouseover/out events with clicking actions

I am brand new to programming and seeking some guidance. I came across a post about mouseover/out combined with click behavior that I found intriguing. However, I am struggling to implement it successfully in my code.

Here is the code snippet:

Child.html

<div id="custom_div">This div will be highlighted</div>

Parent.html

<iframe id="iframeID" src="Child.html"></iframe>    
<a href="#" id="custom_Link">Click to highlight the custom div in Child.html</a>

<script>
    $('#iframeID').contents().find('#custom_div');

    $('#custom_Link').hover(function () {
        $('#custom_div').toggleClass('highlight'); 
    });

    $('#Custom_Link').click(function (e) {
       $('#Custom_div').addClass('highlight');
       $(e.currentTarget).unbind('mouseenter mouseleave');
    });
    </script>

My goal is to achieve the following:

  1. When the user hovers over "custom_link", the "custom_div" should be highlighted.
  2. Once the user moves the mouse away from "custom_link", the highlight on "custom_div" should disappear.
  3. If the user clicks on "custom_link", "custom_div" should be highlighted. But even after moving the mouse away, the 'highlightDiv' remains added to "custom_div".

I have been struggling with accessing iframe elements using Jquery and would appreciate any help or insights you can provide. It would be really helpful if you could also provide a Jsfiddle example for better understanding.

Answer №1

If I have correctly understood your requirements, the provided solution should help resolve this issue.

 <script type="text/javascript">
  $(window).load(function (){
       var iframe_div = $('#iframeID').contents().find('#custom_div');
           $('#custom_Link').hover(function () {
                 iframe_div.toggleClass('highlight'); 
             });
         $('#Custom_Link').click(function (e) {
             iframe_div.addClass('highlight');
            $(e.currentTarget).unbind('mouseenter mouseleave');
         });

    });
 </script>  

Answer №2

I have found a solution for you on this fiddle: http://jsfiddle.net/W4dUa/. It should address your issue, but there are some key points to keep in mind:

Firstly, remember that classes and IDs are case sensitive. Take a look at your code where you have instances like $('#Custom_Link') with an uppercase C, which is not the same as id="custom_Link".

It seems like the problem arises from unbinding mouseenter mouseleave when clicking:

   $(e.currentTarget).unbind('mouseenter mouseleave');

You can read more about this behavior on http://api.jquery.com/hover/:

The .hover() method binds handlers for both mouseenter and mouseleave events.

Due to this, the following code snippet:

$('#custom_Link').hover(function () {
    $('#custom_div').toggleClass('highlight'); 
});

No longer functions as intended, resulting in the highlight class persisting on your div.
