How would I convert HTML into text using jQuery?

I would like to make it so that the children of any element with the "snippet" class are read as text instead of HTML. I am aware that to do this, I would need to change the < and > signs so that the HTML page reads them as text. I have been trying to do this but unfortunately, I only have:

function(){
$('.snippet') 
}

You can use jQuery's .text() function which will remove HTML tags:

var text_only = $('.snippet').text();

Here is a demonstration: http://jsfiddle.net/meZjw/

Docs for .text(): http://api.jquery.com/text

UPDATE

Sime Vidas has a good point, you can iterate through the different .snippet elements changing their HTML structure one at a time:

$.each($('.snippet'), function (index, obj) {
    var $this = $(this);
    $this.html($this.text());
});

Here is a demo using $.each(): http://jsfiddle.net/meZjw/1/

UPDATE

Aepheus has a good point, I don't know if this is what is being asked but you can make a function that will escape HTML entities like in other languages:

function htmlEntities(str) {
    return String(str).replace(/&/g, '&amp;').replace(/</g, '&lt;').replace(/>/g, '&gt;').replace(/"/g, '&quot;');
}

Here is demo: http://jsfiddle.net/meZjw/2/

UPDATE

You can also use .text() and .html() in the opposite order as my above example, to the effect of showing the HTML of an element as plain-text:

$.each($('.snippet'), function (index, obj) {
    var $this = $(this);
    $this.text($this.html());
});

Here is a demo: http://jsfiddle.net/meZjw/31/

This is what I use: 

<span class="snippet">Who me? Why thank you.</span>
<div id="show_text"></div>
<script type="text/javascript" charset="utf-8">
 (function($) {

  var data = $('.snippet').text(); // or how ever you collect the data Object

  $('div#show_text').append( decodeURIComponent(jQuery.param(data)) );

 // debug report:
  if($.browser.mozilla){ //If you talk the talk, then you should toSource()
     console.log(data.toSource());
  }else{
     console.log(data);
  }  
 })(jQuery);
</script>

cut out the parts that you need.

This should work:

$('.snippet').each(function() {
  $(this).text($(this).html());
});

Maybe you want your code to be shown? http://jsfiddle.net/vVgvt/4/

$('.snippet').html().replace(/</g, "&lt;").replace(/>/g, "&gt;");
