禁用属性在firefox中不起作用 - 对于div [英] disabled attribute does not work in firefox - for a div

问题描述

亲爱的朋友：

下面的代码在ie9中完美工作，但在firefox 3.6中无法正常工作

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

ctl00_ContentPlaceHolder1_RadUploadImage - >是div元素

意思是当我们用萤火虫检查这个div时，显示我们禁用=禁用

但我有一个RadUpload在那个工作仍在工作的div！

html代码如下所示：

 < div disabled =trueid =ctl00_ContentPlaceHolder1_RadUploadImageclass =RadUpload RadUpload_BlackByMe RadUpload_rtl RadUpload_BlackByMe_rtlstyle =width：325px;> 
< input autocomplete =offid =ctl00_ContentPlaceHolder1_RadUploadImage_ClientStatename =ctl00_ContentPlaceHolder1_RadUploadImage_ClientStatetype =hidden> 
< ul class =ruInputsid =ctl00_ContentPlaceHolder1_RadUploadImageListContainer>< li>< span class =ruFileWrap ruStyled>< input style =position：absolute; left：0px; -5000px; class =ruFileInputsize =23dir =ltrid =ctl00_ContentPlaceHolder1_RadUploadImagefile0name =ctl00_ContentPlaceHolder1_RadUploadImagefile0type =file>< input size =22class =ruFakeInputtype =text >< input class =ruButton ruBrowsevalue =selecttype =button>< / span>< input name =ClearInputclass =ruButton ruClearvalue =eraseid = ctl00_ContentPlaceHolder1_RadUploadImageclear0type =button>< / li>< / ul>< / div> 
  

有什么想法吗？

预先感谢

解决方案

如果您使用的是jQuery< 1.6这样做：

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

如果您使用的是jQuery 1.6 +：

  $（'＃ctl00_ContentPlaceHolder1_RadUploadImage'）。prop（disabled，true）; 
  

看到这个问题：

这里给出了相同的答案：。prop（）vs .attr https://stackoverflow.com/questions/6048022/jquery-attrdisabled-disabled-not-working-in-chrome\">jQuery .attr（禁用，禁用）在Chrome中无法使用

hi my dear friends :
the below code works perfect in ie9 , but does not work in firefox 3.6

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

ctl00_ContentPlaceHolder1_RadUploadImage -> is a div element

mean when we check this div with firebug , shows us disabled="disabled"
but i have a RadUpload Inside that div that is working still!

the html code is like below :

<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>

any idea?

thanks in advance

解决方案

if you are using jQuery < 1.6 do this:

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

If you are using jQuery 1.6+:

$('#ctl00_ContentPlaceHolder1_RadUploadImage').prop("disabled", true);

See this question: .prop() vs .attr() for references why.

Same answer was given here: jQuery .attr("disabled", "disabled") not working in Chrome
