jQuery Xpath选择器以选择ID包含"sometext"的元素 [英] jQuery Xpath selector to select an element which id contains 'sometext'

问题描述

我在aspx页面中有一个listbox元素，其ID为attributesList.

I have a listbox element in aspx page which id is attributesList.

我想选择此元素以跟踪其更改事件，但是我无法直接选择其ID，因为asp.net在运行时会更改其ID.

I want to select this element to track its change event, but i cant directly select its id because asp.net changes its id on runtime.

其ID，attributesList更改为ctl00_adminPlaceHolder_attributesList.

its id, attributesList changes into ctl00_adminPlaceHolder_attributesList.

所以我要做的是使用包含" xpath表达式来选择元素.

so what i want to do is to use a "contains" xpath expression to select the element.

推荐答案

您将要改用，如下所示:

You'll want to instead use the "End with" attribute selector like so:

$("*[id$='attributesList']")
