How do you select all id tags that contain a certain string in javascript?
提问by Alex
I have an ASP.NET application that renders multiple questions with the option to provide an explanation for the answers given.
我有一个 ASP.NET 应用程序，它呈现多个问题，并提供对给出的答案进行解释的选项。
<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>
so you will have id's like "[X].toggleExplanation_Y" corresponding to "[X].AnswerExplanation_Y"
所以你会有像“[X].toggleExplanation_Y”这样对应于“[X].AnswerExplanation_Y”的id
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.
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，我应该能够从那里获得其余部分。

If your using jquery you can use this to select everything containing "toggleExplanation"
如果您使用 jquery，您可以使用它来选择包含“toggleExplanation”的所有内容
$("[id*='toggleExplanation']")

Give all the .toggleExplanation_divs a unique marker CSS class. Then you can simply use jQuery to select all elements with that class.
给所有的.toggleExplanation_div 一个唯一的标记 CSS 类。然后您可以简单地使用 jQuery 选择具有该类的所有元素。
