- 1 "The .load() method, unlike $.get(), allows us to specify a portion of the remote document to be inserted. This is achieved with a special syntax for the url parameter. If one or more space characters are included in the string, the portion of the string following the first space is assumed to be a jQuery selector that determines the content to be loaded." – j08691 Commented Mar 29, 2013 at 20:26

Why don't you post the content of
asdfasdf.phpthat way it can be a bit clearer what you are trying to do. Thank you. – Marc Audet Commented Mar 29, 2013 at 20:35

Reset to default 4I think you want a space:
$('body').load(url + " #link");
http://api.jquery./load/#loading-page-fragments
All you seem to want is the href of the a#link element at that URL. So instead of loading it into the <body>, just make the AJAX request, and look through the result:
$.ajax({
type: "GET",
url: "http://localhost/test/asdfasdf.php",
dataType: "html"
}).done(function (data) {
var the_link = $(data).find("#link");
alert(the_link.attr("href"));
});
And to put the href in the <body>, add this line in the .done() method:
$("body").html(the_link.attr("href"));
// or
$("body").append(the_link.attr("href"));
But if you actually want to load the a#link element into <body>, do what you had before, but then look for the a#link element and get its attribute:
$('body').load(url + " #link", function () {
var the_link = $("#link");
alert(the_link.attr("href"));
});
EDIT
You're trying to capture the href of the <a> on a different page. A try:
$.get(url+' #link', function(data) {
var $link = $(data).find('a').attr('href');
alert($link);
});
That is my very best guess, but its a shot in the dark.
Currently your code evaluates to .load('http://localhost/test/asdfasdf.php#link'), where #link is a useless fragment. You need a space to engender jQuery's special behavior of automatic DOM parsing and element loading.
$("body").load(url + " #link");
EDIT: to get the actual link value:
$.get(url).done(function (html) {
console.log($(html).find('#link').attr('href'));
});
You can also append to body inside of the .done callback.
