Stealing mouse events through Iframe

I've implemented a Javascript scroller class on a website that seamlessly adds a scrollbar to predefined elements with overflowing content. The client now wants to include an iframe in one of these elements to add interactive content easily. Despite my reservations about iframes, I'm just a subcontractor on this project and have limited influence.

Thankfully, the iframe's content is sourced from the same domain, allowing me to resize the iframe once the content loads and trigger the Javascript scrollbar. Everything works flawlessly in Chrome, but in Internet Explorer and Firefox, the iframe appears to capture mouse events as soon as the cursor hovers over it. As a result, the mousewheel event stops working. While scrolling by dragging the handle or clicking on the track still functions, using the mousewheel does not register any action - the event isn't even triggered.

I've noticed others facing similar issues but haven't come across a suitable workaround. Does anyone have any suggestions?

For reference, here's the Scroll class:

Any assistance will be greatly appreciated!

Answer №1

Mouse events are connected to windows, and iframes function as windows too. It's quite impressive that this setup functions properly in webkit browsers.

To make it work smoothly, you'll have to transfer the event listener and potentially the event handler between the parent window and the iframes whenever the mouse enters them.

For more information on transferring objects between iframes, check out this reference: .

Answer №2

I managed to solve the issue successfully. For the solution, please refer to the jsfiddle link provided below.

http://jsfiddle.net/6nnMV/358/

In my approach, I implemented an event listener for mouse scrolling and attached it to the iframe element.

To scroll the parent window or element, you can utilize the scrollTop property as shown below:

$(element).scrollTop($(element).scrollTop() + (number of pixels));

It's important to note that this method will only be effective if the iframe being accessed is within the same domain.
