用于ID为1的jQuery选择器 [英] jQuery Selector for Select with ID:1

问题描述

我选择了以下具有不寻常的ID/名称属性的选择:

I have the following select with an unusual ID/Name attribute:

<select name="customfield_10021:1" id="customfield_10021:1" class="select cascadingselect-child">

这似乎不允许我选择:

unit = $('#customfield_10021:1 option:selected').text();

http://jsfiddle.net/stzPQ/

uncaught exception: Syntax error, unrecognized expression: 1

如何选择此字段?我以前从未见过这种特殊的语法，但显然可以在Submit上使用.

How can I select this field? I've never even seen this particular syntax before, but it apparently works on submit.

谢谢！

讨厌

推荐答案

使用\\

unit2 = $('#customfield_10021\\:1 option:selected').text();

更新了jsfiddle

Updated jsfiddle

或者您可以将document.getElementById("customfield_10021:1")用作选择器的上下文.

Or you can use document.getElementById("customfield_10021:1") as the context for your selector.

var s = document.getElementById("customfield_10021:1");
unit2 = $('option:selected', s).text();
