使用jQuery创建新元素的正确方法或更好的方法是哪种？ [英] Which is the correct or better way to create a new element with jQuery?

问题描述

相关的答案 https://stackoverflow.com/a/10619477/1076753 来清理元素更好使用

  $（< div>，{id：foo，class：a}）; 
  

或

  $（< div />，{id：foo，class：a}）; 
  

它们都有效，但哪个更好或更正确使用？

官方的 API文档表示，为确保跨平台兼容性，片段必须格式良好。可以包含其他元素的标签应与结束标记配对：

  $（< a href ='http：/ /jquery.com'></a>）; 
  

而不能包含元素的标签可能会被快速关闭或不能：

  $（< img>）; 
 $（< input>）; 
  

因此，最后使用前两个选项之一是错误的 div ？？？？？？？？字节更短。

一旦您开始考虑可读性和其他不那么实际的考虑因素，它主要是一个意见问题。

因此，最后使用div的前两个选项之一是错误的？

不，该部分仅适用如果HTML比没有属性的单个标签更复杂

Related to the answer https://stackoverflow.com/a/10619477/1076753 to cleate an element is better to use

$("<div>", {id: "foo", class: "a"});

or

$("<div />", {id: "foo", class: "a"});

They both works, but which is better or correct to use?

The official API Documentation says that to ensure cross-platform compatibility, the snippet must be well-formed. Tags that can contain other elements should be paired with a closing tag:

$( "<a href='http://jquery.com'></a>" );

while Tags that cannot contain elements may be quick-closed or not:

$( "<img>" );
$( "<input>" );

So, at the end it's wrong to use one of the first two options for a div?

解决方案

If you go solely by metrics that can be easily measured: The first is better because it is 2 bytes shorter.

Once you start accounting for readability and other less tangible considerations, it becomes largely a matter of opinion.

No, that section only applies "If the HTML is more complex than a single tag without attributes"
