jQuery, get html of a whole element [duplicate]
I wish to get the entire html of a selected element not just it's contents. .html() uses javascripts innerHTML() method according to the documentation. HTML:
<div id="divs">
<div id="div1">
<p>Some Content</p>
</div>
<div id="div2">
<p>S开发者_StackOverflow中文版ome Content</p>
</div>
</div>
Using $('#divs:first').html();
will return just the paragraph element. I want to get the html for the whole element, like so:
<div id="div1">
<p>Some Content</p>
</div>
I can't use .parent because this will return html of both child divs.
You can clone it to get the entire contents, like this:
var html = $("<div />").append($("#div1").clone()).html();
Or make it a plugin, most tend to call this "outerHTML", like this:
jQuery.fn.outerHTML = function() {
return jQuery('<div />').append(this.eq(0).clone()).html();
};
Then you can just call:
var html = $("#div1").outerHTML();
Differences might not be meaningful in a typical use case, but using the standard DOM functionality
$("#el")[0].outerHTML
is about twice as fast as
$("<div />").append($("#el").clone()).html();
so I would go with:
/*
* Return outerHTML for the first element in a jQuery object,
* or an empty string if the jQuery object is empty;
*/
jQuery.fn.outerHTML = function() {
return (this[0]) ? this[0].outerHTML : '';
};
You can achieve that with just one line code that simplify that:
$('#divs').get(0).outerHTML;
As simple as that.
You can easily get child itself and all of its decedents (children) with Jquery's Clone() method, just
var child = $('#div div:nth-child(1)').clone();
var child2 = $('#div div:nth-child(2)').clone();
You will get this for first query as asked in question
<div id="div1">
<p>Some Content</p>
</div>
