I use $.ajax() to get some HTML pages from my server. The retrun contains the full HTML result. But i am only interested in a very specific div inside this document.

The only give开发者_JAVA技巧n thing is that my ajax success function returns a JSON object. I have made a PHP proxy file i use for other stuff that returns me a JSON object with the headers, some information to the file I'm loading and its contents. So basically i have a string containing the whole HTML of the page.

Actually i make it like that: $($(data.content)[21]) but this is awful example of jquery (Because i use the $ selector twice, and the HTML could by changing and the div I'm interested in could be changing position in the jquery array). I would like to get only the div <div id="items">...</div> and its contents and only then select it with jquery.

What is the best practice for this case? What would your approach look like?

PS: in case that my example is not clear, your can see an example here: http://meodai.ch/content_slider/


success: function(result) {
    var div = $(result).filter('#items');
}


Try this:

var $items = $(data.content).find('#items')

or if #items is at the top level of the <body>, then do this instead:

var $items = $(data.content).filter('#items')
  • http://api.jquery.com/find/
  • http://api.jquery.com/filter/


Once you parse the JSON response and get the HTML out of it, wrap it in a jQuery object:

var $j = $(htmlGoesHere);

Then, extract the HTML of the div:

var itemsHTML = $j.find("#items").html();
