使用jQuery按名称定位输入字段 [英] Target input field by name using jQuery

问题描述

我有一个看起来像这样的输入字段:

I have an input field that looks like this:

<input type="hidden" name="submitted[event_email]" value="">

我试图更改它的值，并尝试了以下方法:

I was trying to change the value of it and tried this:

jQuery('submitted[event_email]').val('test');

我想以名称为目标，但是我不确定自己做错了什么.有人可以帮忙吗?

I would like to target it by the name, but i am not sure what i did wrong. Would anyone be able to help?

推荐答案

您需要使用

You need to use attribute equals selector [name="value"]

也来自 文档 :

Also from the docs:

使用任何元字符(例如 ！#$％&'((*)，+/.;< =>?@ [] ^`{|}〜)作为名称的文字部分，必须 用两个反斜杠转义:\\

To use any of the meta-characters ( such as !"#$%&'()*+,./:;<=>?@[]^`{|}~ ) as a literal part of a name, it must be escaped with with two backslashes: \\

因此您可以这样做:

jQuery('input[name="submitted\\[event_email\\]"]').val('test');

---

但是实际上您不必在这里转义[ ]，因为它用引号引起来了:

---

But actually you don't need to escape the [ ] here since it's wrapping in quotes:

jQuery('[name="submitted[event_email]"]').val('test');
