本文介绍了jQuery change id!的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我是一个jQuery noobie,并一直在尝试添加一个脚本来更改div onClick的id。
这里是一个 jsfiddle example 。
$ function accept(){
pre>
$(div:scrollwrap)。attr('scrollwrap','highlight');
});
感谢:)
解决方案
attr
应为属性名称,而不是当前值:$ accept(){
$(div#scrollwrap)。attr('id','highlight');
});
但是,阅读你的jsFiddle代码,你看起来有一个高亮类,而不是一个ID。 这是我编辑的版本,我认为您正在尝试实现。
请注意,我已经更改了以下内容:
- 通过添加ID来使.hightlight类更具体
- 删除了inClick onClick,因为您可以在脚本中执行此操作,这被认为是最佳实践(请参阅JS的
.click()
添加) - 更改了JS函数来切换类,因为我假设如果用户取消选择复选框, li>

I am a jQuery noobie, and have been trying to add a script to change the id of a div onClick.
Here is a jsfiddle example.
$(function accept() {
$("div:scrollwrap").attr('scrollwrap','highlight');
});
Thanks :)
解决方案
The first parameter of attr
should be the attribute name, not the current value:
$(function accept() {
$("div#scrollwrap").attr('id','highlight');
});
However, reading your jsFiddle code, you appear to have a class of highlight and not an ID. Here is my edited version with what I think you are trying to achieve.
Note that I have changed the following:
- Made the .hightlight class more specific by adding the ID, otherwise the highlight style will not override the original.
- Removed the inline onClick as you can do this within your script, which is considered best practice (see JS for the
.click()
addition) - Changed the JS function to toggle the class, as I assume it should be invalidated if the user deselects the checkbox.
