Question

I don’t understand why this doesn’t work. I have a div with an iframe inside. I applied jQuery resizable() to the div and set the “alsoResize” option to my iframe. This is how it’s implemented:

$("#my-frame-wrapper").resizable({
    alsoResize : '#myframe'
});

Basically, I was trying to implement resizable() directly to the iframe, but it wouldn’t work, so I tried this method.

The problem is:

If I stretch the div, it works (resizes), but it doesn’t want to retract (if I drag back). Instead, it just goes completely out of control (in Chrome) and it starts bouncing up and down on every mouse-move (very annoying I must add).

Is there anything I am missing? Has anyone else experienced this problem?

Mouse event inside the iframe element won’t get out, so JQuery UI didn’t react when you drag back.

In order to prevent iframe from capturing mouse event, you can add a mask div when drag is start.

html:

<div id="my-frame-wrapper">
    <iframe id="my-frame" src="http://jsfiddle.net/"></iframe>
    <div id="mask"></div>
</div>

css:

#my-frame-wrapper {
    width:200px;
    height:100px;
    position:relative;
}
#my-frame {
    width:100%;
    height:100%;
}
#mask {
    position:absolute;
    top:0;
    left:0;
    margin:0;
    padding:0;
    width:100%;
    height:100%;
    display:none;
}

js:

$(function(){
    $("#my-frame-wrapper").resizable({
        start: function(event, ui) {
           $("#mask").css("display","block");
        },
        stop: function(event, ui) {
           $("#mask").css("display","none");
        }
    });
});
