我如何在< select>中添加disabled = disabled属性使用jQuery吗? [英] How do i add disabled=disabled attribute to <select> using jQuery?

问题描述

我有一个html字段.

I have a html field.

<select name="select-states" disabled="disabled"><option value="">Choose State &raquo;</option></select>

该字段最初是禁用的，我想根据事件启用或禁用它.要启用它，我正在使用以下效果很好的jQuery.

initially the field is disabled, i want to enable or disable it based on events. to enable it i am using the following jQuery which works fine.

$('select[name="select-states"]').removeAttr('disabled');

我想使用jQuery重新启用它，对此我尝试使用它不起作用.

I want to re-enable it using jQuery, for which i tried using this which does not work.

$('select[name="select-states"]').attr('disabled');

我想念什么?正确的语法是什么?

What am i missing? which is the correct syntax for this?

谢谢

推荐答案

在您的代码中，您仅向 .attr() .这表明该函数应只返回该元素的disabled属性的值.

In your code, you provide only one parameter to .attr(). This indicates that the function should just return the value for the disabled attribute of that element.

要设置disabled属性，提供属性名称(第一个参数)以及值(第二个参数):

$('select[name="select-states"]').attr('disabled', 'disabled');
