I asked at Parsing HTML String with jQuery how I can use jQuery on an html string. That all works, but when I apply it to ajax - it does not work. Here is the code.
<script>
var url = 'moo.html';
$.ajax({
url: url,
success: function ( code )
{
html = $(code);
html.each(function() {
alert( $(this).html() );
});
}
});
</script>
moo.html contains
<div id='test'>zebra</div>
<div id='foo'>bar</div>
How can I get zebra and bar?
I think newlines in moo.html may be tripping you up.
Any newlines in your html will end up being parsed by jQuery and kept as text node elements "\n". As a result $(code).each will stop iterating when the first of these nodes is hit and you call .html() on it (html() does not operate on non-Element node types).
What you need is to grab only the divs in your html:
var divs = $(code).filter(function(){ return $(this).is('div') });
divs.each(function() {
alert( $(this).html() )
})
.html does not operate on non-Element nodes.Try:
html = $("div", code);
html.each(function() {
alert($(this).html());
});
The reason you can't do it the way you have it, is because when parsing HTML jQuery wants to have a single root element. If it doesn't then you have to do it the way above. The following HTML/JS would also work:
var html = $(code);
html.children().each(....);
<div>
<div id='test'>zebra</div>
<div id='foo'>bar</div>
</div>
alert($('<div></div><div></div>').length) results in "2".
try $('div', code).each instead.. like so...
$('div', code).each( function () {
alert($(this).text());
});
I haven't tested it though...
