jQuery将css类更改为div [英] jQuery changing css class to div

问题描述

如果我有一个div元素为例，类'first'定义了许多css属性。

解决方案

我可以将css类'second'指派给同样的div， div>

  $（。first）。addClass（second）; 
  

如果您想在活动中添加它，您也可以轻松地添加。点击事件的示例：

  $（。 （this）.addClass（second）; 
}）; 
  

If I have one div element for example and class 'first' is defined with many css properties. Can I assign css class 'second' which also has many properties differently defined to this same div just on some event without writing each property in line.

解决方案

$(".first").addClass("second");

If you'd like to add it on an event, you can do so easily as well. An example with the click event:

$(".first").click(function() {
    $(this).addClass("second");
});
