jQuery .find() on data from .ajax() call is returning "[object Object]" instead of div

Trying to find div element with id="result" in returned data from .ajax() using .find(). Unfortunately, alert(result) doesn't return di开发者_运维百科v#result.

Here is my code:

$.ajax({
    url: url, 
    cache: false,
    success: function(response) {
        result = $(response).find("#result");
        alert(response); // works as expected (returns all html)
        alert(result); // returns [object Object]
    }
});

To answer your question specifically, it seems to be working correctly. You said that it returns [object Object], which is what jQuery will return with the find("#result") method. It returns a jQuery element that matches the find query.

Try getting an attribute of that object, like result.attr("id") - it should return result.

In general, this answer depends on whether or not #result is the top level element.

If #result is the top level element,

<!-- #result as top level element -->
<div id="result">
  <span>Text</span>
</div>
<div id="other-top-level-element"></div>

find() will not work. Instead, use filter():

var $result = $(response).filter('#result');

If #result is not the top level element,

<!-- #result not as top level element -->
<div>
  <div id="result">
    <span>Text</span>
  </div>
</div>

find() will work:

var $result = $(response).find('#result');

I just spent 3 hours to solve a similar problem. This is what worked for me.

The element that I was attempting to retrieve from my $.get response was a first child element of the body tag. For some reason when I wrapped a div around this element, it became retrievable through $(response).find('#nameofelement').

No idea why but yeah, retrievable element cannot be first child of body... that might be helpful to someone :)

try this:

result = $("#result", response);

btw alert is a rough way to debug things, try console.log

this is your answer:

<div class="test">Hello</div>
<div class="one">World</div>    

The following jQuery Won't work:

$(data).find('div.test');    

as the divs are top level elements and data isn't an element but a string, to make it work you need to use .filter

$(data).filter('div.test');    

Another same question: Use Jquery Selectors on $.AJAX loaded HTML?

do not forget to do it with parse html. like:

$.ajax({
    url: url, 
    cache: false,
    success: function(response) {
        var parsed = $.parseHTML(response);
        result = $(parsed).find("#result");
    }
});

has to work :)

This worked for me, you just need to put .html() on the end of - $(response).find("#result")

The jQuery find() is returning a jQuery object that wraps the DOM object. You should be able to work with that object to do what you'd like with the div.

The thing is that your ajax response is returning a string, so if you use directly $(response) it would return JQUERY: Uncaught Error: Syntax error, unrecognized expression in the console. In order to use it properly you need to use first a JQUERY built-in function called $.parseHTML(response). As what the function name implies you need to parse the string first as an html object. Just like this in your case:

$.ajax({
    url: url, 
    cache: false,
    success: function(response) {
        var parsedResponse = $.parseHTML(response);
        var result = $(parsedResponse).find("#result");

        alert(response); // returns as string in console
        alert(parsedResponse); // returns as object HTML in console
        alert(result); // returns as object that has an id named result 
    }
});

Specify dataType: "html".

If you do not jQuery will guess the requested data type (check: http://api.jquery.com/jQuery.ajax/). My guess is that in your case response was a String rather than a DOMObject. Obviously DOM methods won't work on a String.

You could test that with console.log("type of response: " + typeof response) (or alert("type of response:" + typeof response), in case you don't run Firebug)

You can do it in this way to find any div and get its attributes or anything you want.

$(response).filter('#elementtobefindinresponse').attr("id");

or

$(response).filter('img#test').attr("src");

Is #result in the response HTML? Try the following. jQuery will still return an empty object if it doesn't find anything.

alert(result.length);

You should add dataType: "html" to the request. Im quite sure you wont be able to search the DOM of the returned html if it doesnt know it is html.

you just use the following code

var response= $(result);

$(response).find("#id/.class").html(); [or] $($(result)).find("#id/.class").html();

$.ajax({
    url: url,
    cache: false,
    success: function(response) {
        $('.element').html(response);
    }
});

< span class = "element" >
    //response
    < div id = "result" >
        Not found 
    </div> 
</span>

var result = $("#result:contains('Not found')").text();
console.log(result); // output: Not found

try if( $(response).filter('#result').length ) // do something

To view the content in alert use:

alert( $(response).find("#result").html() );

You might have to do something like

var content= (typeof response.d) == 'string' ? eval('(' + response.d + ')') : response.d

then you should be able to use

result = $(content).find("#result")
