jQuery：removeAttr（" disabled"）无法在Firefox上运行 [英] jQuery: removeAttr("disabled") not working on Firefox

问题描述

我有一些代码看起来像是从XHR回复中回来的：

I have some code that looks like the following coming back from an XHR response:

jQuery(':text:not(:hidden)').removeAttr("disabled");

这是在表单提交后禁用输入字段的结果。 XHR响应返回jQuery的这个小节点并重新启用控件。适用于所有浏览器，甚至可以部分在FF 3.6.1 OSX上运行。我的意思是部分文本字段删除了禁用属性，其他文本字段没有删除。验证这些文本字段不被隐藏。

This is a result of input fields being disabled after form submit. The XHR response returns this tidbit of jQuery and re-enables controls. Works great on every browser, even "partially" on FF 3.6.1 OSX. What I mean by partially is that some text fields have the disabled attribute removed, others do not. These text fields are verified not hidden.

推荐答案

请改用它：

jQuery('input:text:visible').each(function(){
    this.disabled = false;
});

这使用元素的已禁用属性直接而不是搞乱jQuery包装器。

This uses the disabled property of the element directly, rather than messing around with jQuery wrappers.
