如何使用jQuery中新的已加载页面标题更改.load（）上的页面标题

Question

I'm confused about the .load() and $.ajax . I have the following jQuery code in my index.html :

$('.load_ext').click(function(e) {    
    var url = $(this).attr("href");
    parentContainer.append($(document.createElement("div")).load(url + ' #content_to_load').html('<p class="loading">Loading&#8230;</p>').hide().fadeIn('slow'));
})

and HTML:

<a href="test.html" class="load_ext">test</a>

In the example above, I'm loading partial content from the test.html (the content of id #content_to_load ). I also want to grab the title of that test.html page and replace the index.html title page with that one.

I tried doing something like:

var url = $(this).attr("href");
parentContainer.append($(document.createElement("div")).load(url + ' #content_to_load', function() { 
     console.log($(document).attr('title'));
}).html('<p class="loading">Loading&#8230;</p>').hide().fadeIn('slow'));

without any luck. It gives me the current page title. How can I replace the title by doing something like:

$('title').text(newPageTitle);

Thanks!

EDIT: Thanks to @Jeff Schafer, @dystroy, and @zeroflagL I managed to solve this problem. Here's the changed code:

var url = $(this).attr("href");
parentContainer.append($(document.createElement("div")).load(url + ' #content_to_load', function(responseText) {
  var title = responseText.match(/<title>([^<]*)/)[1];
  document.title = title;
}).html('<p class="loading">Loading&#8230;</p>').hide().fadeIn('slow'));

Answer 1

The main problem with load is that jQuery, when building the DOM fragment, strippes what isn't the body. You can use this to get the title of a distant page :

$.get(url, function(html){
    var matches = html.match(/<title>([^<]*)/);
    if (matches.length>0) {
        var title = matches[1];
        document.title = title;
    }
});

Note that this won't work if the distant page is from a different origin and doesn't specifically allow cross-domain requests.

Answer 2

You can get the title of the new page through the responseText:

.load(url + ' #content_to_load', function(responseText) {

repsonseText is literally text, though, the source code of the page. You can use regular expressions, for instance, to extract the title of test.html . Then you can change the title with document.title = newTitle .

Answer 3

try this code to change page title

document.title = newPageTitle;

hope it helps
