jQuery：将div附加为var类

Question

I have a line that appends a new div to an existing one. However I also want to add a class to the new div. The class's name is actually held in a var.

I am just unsure of the syntax of this - could anyone point me in the right direction at all?

 var itemclass = "myclass";

 $('#wrapper').append('<div class="itemclass"></div>');

So far I have tried:

 $('#wrapper').append('<div class=" . itemclass . "></div>');

 $('#wrapper').append('<div class=" & itemclass & "></div>');

To no effect... any help is appreciated!

Answer 1

您正在串联一个字符串，它的完成方式如下：

$('#wrapper').append('<div class="' + itemclass + '"></div>');

Answer 2

JS使用+连接项目，如下所示：

 $('#wrapper').append('<div class="' + itemclass + '"></div>');

Answer 3

串联是javascript中的+号，而不是PHP中的句点
