如何禁用动态添加到HTML的文本区域?

How to disable a textarea which is dynamically added to the HTML?

HTML:

<div class="ss_datesel_inp_cont">
    <div class="ss_datesel_inp_right_corner">
    </div>
    <input autocomplete="off">
</div>

这是我尝试过的:

   $('.ss_datesel_inp_cont:textarea').prop("disabled", true);
   $('.ss_datesel_inp_cont:input').prop("disabled", true);

推荐答案

在您发布的代码中没有看到textarea元素?根据您的标记，您可以通过以下方式禁用输入:

I don't see a textarea element in the code you posted? Based on the markup you have, you would disable the input by:

$('.ss_datesel_inp_cont input').prop('disabled', true);

您的代码无法运行的原因仅仅是因为选择器错误.输入是.ss_datesel_inp_cont的后代，因此您需要使用.ss_datesel_inp_cont和input之间的空格来表示.输入也是直接子代，因此您也可以像$('.ss_datesel_inp_cont > input')一样使用直接子代币>.

The reason your code isn't working is simply because the selector is wrong. The input is a descendant of .ss_datesel_inp_cont and therefore you need to indicate that with a space between .ss_datesel_inp_cont and input. The input is also a direct child, so alternatively you could use the direct child token > as in $('.ss_datesel_inp_cont > input').
