Jquery find all ids starting with a string?
提问by baggins
Just wondered how I would search for all the ids starting with "content_" in the whole page and also a way to only find them in a named div called "extra_content". Once i have all the ids i want to hide them.
只是想知道如何在整个页面中搜索以“content_”开头的所有 id,以及一种仅在名为“extra_content”的命名 div 中找到它们的方法。一旦我拥有了所有的 ID,我就想隐藏它们。
Below is an example of what i want to find.
下面是我想找到的一个例子。
<div id="content_1"></div> <-- Find
<div id="content_2"></div> <-- Find
<div id="contet_3"></div>
<div id="extra_content">
<div id="content_extra_1"></div> <-- Find
<div id="content_extra_2"></div> < -- Find
</div>
Examples would be helpful.
例子会有所帮助。
Thanks
谢谢

Use the attribute-starts-with selector:
使用属性开始选择器:
$('[id^="content_"]').hide();
To limit the search to elements within extra_content
:
将搜索限制为 内的元素extra_content
:
$('#extra_content [id^="content_"]').hide();
