如何使用jQuery将元素转换为字符串

Question

I don't need innerHTML i need innerHTML with enclosing tags. Lets write some example:

<div id="1" style="qwe"><span class="1"></span></div>
<div id="2" style="asd"><span class="2"></span></div>
<div id="3" style="zxc"><span class="3"></span></div>

I can get element by id:

$("#1")

And how can i get string like that:

<div id="1" style="qwe"><span class="1"></span></div>

Of course html() doesn't work becouse it will return only span.

Answer 1

you could do something like this:

alert( $('#\\31 ').wrap("<div />").parent().html() )
$('#\\31 ').unwrap()

Answer 2

Something like this should work fine:

jQuery.fn.outerHTML = function(s) {
    return s
        ? this.before(s).remove()
        : jQuery("<p>").append(this.eq(0).clone()).html();
};

var outer = $("#1").outerHTML();

Here's a working fiddle .

Use this jQuery plugin: https://github.com/brandonaaron/jquery-outerhtml/blob/master/jquery.outerhtml.js

(function($){
  var div;

  $.fn.outerHTML = function() {
    var elem = this[0],
      tmp;

    return !elem ? null
      : typeof ( tmp = elem.outerHTML ) === 'string' ? tmp
      : ( div = div || $('<div/>') ).html( this.eq(0).clone() ).html();
  };

})(jQuery);

Use it as follows:

$('#some-element').outerHTML();

You can use outerhtml but in JavaScript over the DOM and not jQuery , for example:

  var text = document.getElementById('hello').outerHTML;

jsbin code to demonstrate: http://jsbin.com/obutul/edit#javascript,html,live

Answer 5

html元素上还有一个outerHTML属性，它包含所选元素本身。

Answer 6

outerHTML is implemented across nearly all browsers now (including old versions of ie - firefox is the only one dragging its feet, but it's scheduled for v11 ), so I've adapted @James Hill's answer to use this native functionality where present as it should be more efficient.

jQuery.fn.outerHTML = function(s) {
    return this[0].outerHTML ? this[0].outerHTML :
           s ? this.before(s).remove()
             : jQuery("<p>").append(this.eq(0).clone()).html();
};

var outer = $("#1").outerHTML();

Be aware though that there are a few cross-browser inconsistencies in outerHTML (eg look at this page in chrome and compare with ie)

Answer 7

You can wrap the desired div in another div and then fetch the parent div's html.

<div><div id="1" style="qwe"><span class="1"></span></div></div>
<div><div id="2" style="asd"><span class="2"></span></div></div>
<div><div id="3" style="zxc"><span class="3"></span></div></div>

Now,

$("#1").parent().html() will fetch the desired string.
