使用ajax加载特定的div内容

Question

I am using $.ajax to load the page content. In response I am getting whole html document as a string but I want to get the only particular div content from the response by using id of the div. I can't change the response and I can't use $.load method. Thanks in advance.

$.ajax({ 
    url: ajax_url, 
    type: "GET", 
    dataType: "html" 
}).done(function(data) {
}).fail(function(jqXHR, textStatus, errorThrown) { 
});

Answer 1

In your .done() method:

.done(function(data) { 
    $('#target').html($(data).find('#specificDivId'))
})

Answer 2

You can traverse the HTML returned from the request in the same manner you would the DOM of the current page. Try this:

$.ajax({ 
    url: ajax_url, 
    type: "GET", 
    dataType: "html" 
}).done(function(html) {
    var $divToFind = $(html).find('#myDiv');
    $divToFind.appendTo('#targetElement');
}).fail(function(jqXHR, textStatus, errorThrown) { 
    // handle the error...
});

Alternatively, you could use the load() method which has this functionality built in:

$('#targetElement').load(ajax_url + ' #myDiv');

Answer 3

You can use DOM parser.

$.ajax().success(function(data) {

  var parser = new DOMParser();
  var doc = parser.parseFromString(data, "application/xml");

  // doc is a DOM now

});

Answer 4

As AJAX returns a plain text, you can transform it to jQuery DOM element, modify it and append (or replace HTML) to your HTML.

For example, this way:

$.ajax({ 
    url: ajax_url, 
    type : "GET", 
    dataType : "html" 
}).done(function(data) { 
    var obj = $(data);
    $("#yourdiv").html(obj.find(".something").html());
}).fail(function(jqXHR, textStatus, errorThrown) { 

});

I have used .find(".something") because I do not know the format of received message. You can use any jQuery methods.

What you want is basically what ajax shorthand method load() using page frament is doing:

$('#divToAddContent').load(ajax_url + ' #divToGetContent');

(note the space at starting fragment selector string)
