jQuery中的$('< element>')与$('< element/>') [英] $('<element>') vs $('<element />') in jQuery

问题描述

我看到人们以两种不同的方式在jQuery中创建HTML元素:

I see people creating HTML elements in jQuery in two different ways:

$('<element>')

和

$('<element />') 

我很好奇哪个是更正确的".我认为第一个方法的明显优势是只需键入很少的内容.使用哪一个完全不同?

I am curious which one is "more correct". I see the obvious advantage to the first one as being just simply less to type. Does it make a difference at all which one is used?

推荐答案

正如源代码第121行:

There is no difference, as seen in the source code, line 30 & line 121:

/* Line 30*/
rsingleTag = /^<(\w+)\s*\/?>(?:<\/\1>)?$/,

/* Line 121 */
// If a single string is passed in and it's a single tag
// just do a createElement and skip the rest
ret = rsingleTag.exec( selector );

以下等同:

• <a></a>
• <a />
• <a>

• <a></a>
• <a />
• <a>
