所以jQuery 1.6具有新功能prop().

$(selector).click(function(){
    //instead of:
    this.getAttribute('style');
    //do i use:
    $(this).prop('style');
    //or:
    $(this).attr('style');
})

或者在这种情况下,他们做同样的事情？

如果我也有转用prop(),所有的旧attr()电话,如果我切换到1.6将打破？

UPDATE

selector = '#id'

$(selector).click(function() {
    //instead of:
    var getAtt = this.getAttribute('style');
    //do i use:
    var thisProp = $(this).prop('style');
    //or:
    var thisAttr = $(this).attr('style');

    console.log(getAtt, thisProp, thisAttr);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.0/jquery.min.js"></script>
<div id='id' style="color: red;background: orange;">test</div>

控制台会记录getAttribute作为一个字符串,并attr作为一个字符串,但prop作为一个CSSStyleDeclaration,为什么？这对我未来的编码有何影响？

亲爱的朋友们:
以下代码在ie9中运行完美,但在firefox 3.6中不起作用

$('#ctl00_ContentPlaceHolder1_RadUploadImage').attr('disabled', 'disabled');

ctl00_ContentPlaceHolder1_RadUploadImage - >是一个div元素

意思是当我们用firebug检查这个div时,显示我们disabled ="disabled"
但是我有一个RadUpload Inside那个div仍在工作!

html代码如下:

<div disabled="true" id="ctl00_ContentPlaceHolder1_RadUploadImage" class="RadUpload RadUpload_BlackByMe RadUpload_rtl RadUpload_BlackByMe_rtl" style="width: 325px;">
            <input autocomplete="off" id="ctl00_ContentPlaceHolder1_RadUploadImage_ClientState" name="ctl00_ContentPlaceHolder1_RadUploadImage_ClientState" type="hidden">
        <ul class="ruInputs" id="ctl00_ContentPlaceHolder1_RadUploadImageListContainer"><li><span class="ruFileWrap ruStyled"><input style="position: absolute; left: 0px; top: -5000px;" class="ruFileInput" size="23" dir="ltr" id="ctl00_ContentPlaceHolder1_RadUploadImagefile0" name="ctl00_ContentPlaceHolder1_RadUploadImagefile0" type="file"><input size="22" class="ruFakeInput" type="text"><input class="ruButton ruBrowse" value="select" type="button"></span><input name="ClearInput" class="ruButton ruClear" value="erase" id="ctl00_ContentPlaceHolder1_RadUploadImageclear0" type="button"></li></ul></div>

任何的想法？

提前致谢
