jQuery删除包装元素

Question

I am loading a html file with jquery $.get and wrap the response. But jQuery removes my wrapper .

I made the following example which demonstrates my problem: https://jsfiddle.net/pwm76bp6/

Everyone who dont want to open the link here is the example code:

alert($('<div><div>Hallo</div></div>').html());

I would expect that the whole string should be alerted. Whats the problem here?

Answer 1

您需要阅读outerHTML属性。

 console.log($('<div><div>Hallo</div></div>').prop('outerHTML')); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 

Answer 2

用一个元素动态包装它，然后获取被包装元素的html（）。

alert($('<div><div>Hallo</div></div>').wrap("<div></div>").parent().html());

Answer 3

It doesn't remove your wrapper. jQuery html() does return the contents of an element.

When you do $('<div>my content</div>') you creating an element, then you get the inner html with html() which is then alerted in your example.

Answer 4

With your code you will get the html of your outer element <div> . And the content of the outer <div> is <div>Hallo</div> .

You can do what you want with a default property:

alert($('<div><div>Hallo</div></div>')[0].outerHTML);

Answer 5

the function "html" does return the html content of a given element. In your case "html()" returns the content of the outer div, which excludes the outer itself.

You may can overcome this by wrapping your html like:

var html = '<div><div>Hallo</div></div>';
var outerHtml = $(html).wrap('<div />').parent().html();

hope this helps.
