如何通过jquery更改元素的类名(how to change class name of an element by jquery)

如何通过jquery更改元素的类名(how to change class name of an element by jquery) <div class="bestAnswerControl"> <div id="ct100_contentplaceholder_lvanswer_control_divbestanswer" class="IsBestAnswer"></div> </div>

我想添加：

.bestanswer { // some attribute }

我想把div的class="bestanswer"为jquery的class="bestanswer" 。 我该怎么做？

我使用这种方法：

$('.IsBestAnswer').addclass('bestanswer');

但它不工作。

<div class="bestAnswerControl"> <div id="ct100_contentplaceholder_lvanswer_control_divbestanswer" class="IsBestAnswer"></div> </div>

I want to add:

.bestanswer { // some attribute }

I want to replace class="IsBestAnswer" of div to class="bestanswer" by jquery. How do I do this?

I am using this approach:

$('.IsBestAnswer').addclass('bestanswer');

but it's not working.

最满意答案

$('.IsBestAnswer').addClass('bestanswer').removeClass('IsBestAnswer');

方法名称中的例子很重要，所以没有addclass 。

jQuery addClass() jQuery removeClass()

$('.IsBestAnswer').addClass('bestanswer').removeClass('IsBestAnswer');

Case in method names is important, so no addclass.

jQuery addClass() jQuery removeClass()
