jquery 'change' event not firing on Image-

问题:

Here is an example : http://jsfiddle.net/c8uywnpa/21/ which works on other browsers but IE (10). The issue comes when a the buttonset is wrapped within a 'form' element. Please see example included.

<b> Form - Click on image does not work, must click on number </b>
<form>
<div id="myRadio">
    <input id="rf1" type="radio" name="myRadio" value="1" />
    <label for="rf1">1 <img src="//jsfiddle.net/img/initializing.png" width="50"/> </label>
    <input id="rf2" type="radio" name="myRadio" value="2" /> 
    <label for="rf2">2 <img src="//jsfiddle.net/img/initializing.png" width="50"/> </label>
</div>
</form>
<hr>
<h3> No Form - Click on image works </h3>
<div id="myRadioNoForm">
    <input id="r1" type="radio" name="myRadioNoForm" value="1" />
    <label for="r1">1 <img src="//jsfiddle.net/img/initializing.png" width="50"/> </label>
    <input id="r2" type="radio" name="myRadioNoForm" value="2" /> 
    <label for="r2">2 <img src="//jsfiddle.net/img/initializing.png" width="50"/> </label>
</div>

$("#myRadio").buttonset().on('change', function(event) {
    alert($(this).find(":checked").val()); 
});
$("#myRadioNoForm").buttonset().on('change', function(event) {
    alert($(this).find(":checked").val()); 
});

Clicking on the numbers in the label fires the change event but does not if you click on the Image in the label. Any help is much appreciated.

I had the same problem. I'm not using jQuery. I had the image wrapped with the span, so I tried to add an :after pseudoelement to it. It covers the image, so when clicking, you click on the pseudoelement rather than on the image. And it helped for me. ie9-11

.image { position: relative; display: block;}
.image:after {content:""; position:absolute; top:0; left:0; width:100%; height:100%;}


<label for="answ">
    <span class="image"><img src="image.jpg"></span>
</label>
