如何在javascript中选择包含特定字符串的所有id标签？ [英] How do you select all id tags that contain a certain string in javascript?

问题描述

我有一个ASP.NET应用程序，它提供了多个问题，并提供了给出答案的解释。

I have an ASP.NET application that renders multiple questions with the option to provide an explanation for the answers given.

<label for="[<%:count %>].AnswerExplanation_<%: i+1 %>" id="[<%:count %>].toggleExplanation_<%: i+1 %>"><strong>Add Explanation</strong></label>
<br /><br />
<div id="[<%:count %>].Explanation_<%: i+1 %>">
    <textarea id="[<%:count %>].AnswerExplanation_<%: i+1 %>" name="[<%:count %>].AnswerExplanation_<%: i+1 %>" class="ckedit"></textarea>
</div>

因此您将拥有与[X] .AnswerExplanation_Y相对应的[X] .toggleExplanation_Y的ID

so you will have id's like "[X].toggleExplanation_Y" corresponding to "[X].AnswerExplanation_Y"

我正在编写一个javascript函数来显示/隐藏AnswerExplanation div，并且正在寻找一种方法来选择包含toggleExplanation的每个id我应该能够得到从那里开始。

I am writing a javascript function to show/hide the AnswerExplanation divs, and was looking for a way to select every id containing "toggleExplanation" I should be able to get the rest from there.

推荐答案

尝试使用属性包含收集器

$('label[id*="toggleExplanation"]')
