This is the code, changing a background image for a jQ plugin, Works fine on Chrome, FF, Safari and even my two smart phones. But not IE. Can anyone spot a problem?

<script type="text/javascript">
$(document).ready(function() {
$("#supersized img").attr({ 
          src: "images/bg2.jpg",
        });
    $("#supersized").attr($("img"));
});
</script>

推荐答案

IE在其对象文字形式上非常严格.很多时候，您不希望在最后一个属性后加上逗号.因此，在这种情况下，src属性后的逗号将使IE适合，最著名的是IE 6& 7

IE is very strict on its object literal formation. Many times it does not like you to put a comma after the last property. So in this instance the comma after your src property will give IE fits, most notoriously IE 6 & 7

$("#supersized img").attr({ 
          src: "images/bg2.jpg"  //<-- notice no comma after property value because it's the last one.
        });
    $("#supersized").attr($("img"));
});
