jQuery:选择具有唯一ID的所有输入(正则表达式/通配符选择器) [英] jQuery: select all inputs with unique id (Regex/Wildcard Selectors)

问题描述

我在网络表单上有一些文本框，其ID如下:

I have some textboxes on a webform that have ids like this:

txtFinalDeadline_1
txtFinalDeadline_2
txtFinalDeadline_3
txtFinalDeadline_4

在我的jQuery中，如何找到所有这些以便为它们分配值.在我使用下划线并将它们全部命名为txtFinalDeadline之前，我可以做到这一点，并且确实有效.

In my jQuery how do I find all of those in order to assign a value to them. Before I had the underscore and they were all named txtFinalDeadline I could do this and it worked.

$(this).find("#txtFinalDeadline").val(formatDate);

然而，那是当他们都被命名为同一个东西的时候.现在，名字后面有_x，我不确定如何为他们分配与以前相同的值.

However, that was when they were all named the same thing. Now I have the _x after the name and I'm not sure how to go about assigning that same value as before to them.

推荐答案

我不知道我是否可以保证按顺序"，但该选民应该工作:

I don't know if I can guarantee "in order", but this elector should work:

$(this).find('input[id^=textFinalDeadline_]').val(formatDate);

即使那样，jQuery仍已优化为以特殊方式处理id，并且只能处理1个id.

Even then, jQuery is optimized to handle ids in a special way, and may only process 1 id.

一种更好的方法是让这些文本字段使用一个类(也许是date)，这样您就可以使用'.date'选择器.

A better way would be to have these textfields use a class (perhaps date) so you could just use the '.date' selector.
