The autocomplete (I'm using this one) and the getJSON work perfectly. The problem comes when I try to do something with the returned json data. Line 14 won't work for me. Any selectors I try on the returned json data won't work. The selectors still work on items that were there before the json data was returned.
i am doing an application which make use of JQuery and Cakephp . In this i am using like the following to retrieve the values from my controller side
var getformid; $.getJSON("http://localhost/FormBuilder/index.php/forms/getFormEntry", function(json) { getformid=json.forms[0]["id"];
[code]....
In the above code, the inner alert that is inside $.getJSON gives me the correct value as 75 But the outer alert showing me the error as getformid not defined..Why so??Can't we make use of the getformid available outside $.getJSON .Please suggest me.SInce i want to make use of that value for saving the Field ..
I am trying out $.ajax instead of getJSON for debugging purposes. Because getJSON did not report an error in IE (6,7 or 8) and I am trying to figure out why a jQuery plug-in is not painting my returned images to the screen in IE but is in other browsers. So I tried this. Interestingly enough, it hits the error event in IE but not firefox, safari and the rest and I don't know why (this code works great and renders my data just fine in FireFox and the rest). I know my returned json is valid:
I don't know what else to do to troubleshoot why IE is having so much trouble with the returned JSON or just executing the function(data) using either getJSON OR this. I have set the headers not the cache also in the response. IE refuses to enter my function(data) on the response.
Same result. Firefox and the rest had no issue. IE still exited the $.ajax and my error method kicked in. No rhyme or reason whatsoever and I tried the IE Dev tools... nothing. About the only thing I get is this: Line: 163 Error: System error: -1072896658.Line 163 which is simply the line: function() { alert("An error has occurred. try again."); This has got to be the most f*d up situation I've been in and I need to get this working! I just cannot understand why IE can't parse a getJSON or $.ajax response, that is impossible or else there would be a huge meltdown with jQuery.
I'm trying to assign the values from the JSON data returned when I run this code into an array that's outside the callback function. The data is multidimensional, and I have been able to use this data within the callback function. However I want to use it outside that function. i.e. the jsdata returned in the code below is to be used outside the function
Code: $.getJSON('../fxns/status.php',function(jsdata){ //do some stuff with JSON data or pass to global variable[code]..........
I am doing a few tests with javascript and oop. but one failed so i falled back to the way i usually do this but it still isnt working properly. i am using $.post() but instead of returning whatever is echoed in the php file like it does with all my other scripts it returns the content of the file:
Isnt returned in var data but the whole file is returned as a string.
I'm using a simple dom parser function to catch xpath information of all nodes of a document. Say html is like : HTML Code: <div> <div>Everyday People</div> <div>My name is ACE</div> <div>Hello world</div> </div>
And parsing the DOM to store the xpath infor in array 'arr' Code: <script type="text/javascript" src="js/jquery/js/jquery-1.3.2.min.js"></script> <script type="text/javascript" src="js/jquery/js/xpath-selector.js"></script> <script type="text/javascript"> function get_XPath(elt) {var path = ''; for (; elt && elt.nodeType==1; elt=elt.parentNode) {var idx=$(elt.parentNode).children(elt.tagName).index(elt)+1; idx>1 ? (idx='['+idx+']') : (idx=''); path='/'+elt.tagName.toLowerCase()+idx+path; }return path; }var arr = Array(); htmlDoc=document; x=htmlDoc.documentElement.childNodes; for (i=0;i<x.length;i++){ arr.push(get_XPath(x[i])); } </script> And later on in the script using the values stored in 'arr' to perform some functions like showing,hiding or changing content of nodes.
Code: <script> for(i=0;i<arr.length;i++){ //catch the object reference with the xpath info $(arr[i]) } </script>
But in the snippet above,I'm getting a object but unable to I'm unable to get the object reference..and use it for something like $(arr[i]).text(); Any work on Jquery Xpath selectors?
I have this basic code following and its not returning anything at all. Even the alert is not alerting. I have checked and the select is sending the value fine But nothing happens on return. What i am missing?
I'm using Christophe Beyls' Slimbox 2 to get the lightbox effect on a gallery of Flickr images on my site, and I'm trying to modify it to grab the description of the image and put it in the title of the lightbox. The photo id is already given, but I'm not sure how to get the description out of the anonymous function so I can concatenate it to the linkMapper return (el.title).
Code JavaScript: linkMapper = linkMapper || function(el) { Â var uri = 'http://api.flickr.com/services/rest/?api_key=[key]&format=json&method=flickr.photos.getInfo&photo_id=' + el.id + '&jsoncallback=?'; $.getJSON(uri, function(data) {
The url is a very straightforward servlet that queries a database and returns either Y or N. That part is working fine. The first alert shows Y or N just as it is supposed to.
However, the second alert is always showing Turbo, as though the if statement is not able to compare properly. This is probably javascript rather than specific to jQuery, but can anyone see where I'm going wrong?
I have used getSON() successfully before but I am meeting with an issue which I don't seem to get a hold on. The data object returned is not populated correctly by getJSON(). Am I doing something wrong?
In the code below the second alert is executed before the first one making it show the "empty" content, and not the result from the .json file. Why, and how can I make it work? getjson.html file
Recently i tried to use getJSON to retrieve data from [url] and every time i tested in firefox, the console will always give me error on the line $.each(data.results, function(i,result) saying data is null. i am wondering how to solve this problem?
Yet, when i made the json calls(cross domain), it just return me nothing. However, under the same domain, I got the pop-up alert and return me the relevant data. But getJSON is suppose to be feasible across all domains irrespective of the same-origin policy.
So I'm loading the div#my_events by prepend(data) where "data" is another well styled div. Is there anyway to animate this returned data. Unfortunately I can't just specify a unique ID on the incoming data. So I was wondering how else I might be able to address this data I'm returning.
It is basically a topic list, with a modal that sends jquery to add a topic to the database, and returns the topic from the database, hides the modal, and displays the last added topic at the top of the topic list. Now I'd like it to do something slightly fancy like animate the color of the background to bring the user's attention to it.
Here is what I'm trying to do. I will pass a directory to a PHP script, that script will then return an array of filenames back to the javascript that called it. In the javascript I want to take the filenames returned and create links to them in an unordered list.
The PHP code to get the filenames is done and when I run the script I get an array that I have formatted into json... an example of the encoded array is as follows...
So here is the jquery I'm trying to use to get the filenames and create my links... But I must be missing something because my variable... data ... is empty... but status is Success.
In this dumb example, I'm unable to match the 'data' returned variable with the value I assigned to it in php (I can't manage to enter my 'do stuff'), yet its value is 'ok' if I display it. I have no problem to retrieve html code from php and inject it in my pages, but I can't test it as a regular javascript string.
What's wrong in this ? What have I missed about the 'data' format ? Do I have to 'cast' data to a javascript string (and if so, how ?)
I am currently using $.ajax to post to a Perl file that queries a webservice and returns XML. Running the Perl via command line confirms that XML is being returned with Content-Type: application/xml. However, regardless if I set the dataType parameter to "xml", "XML" or just use jQuery's intelligent guess, it appears that I am not getting any data returned to my function at all.
I've tried using the full $.ajax notation and the simplified $.get notation as follows:
and:
I have also tried using JQuery to perform a "GET" directly to the webservice which returns XML by default and still I get no data returned to my function.
Although I doubt it's browser-related, I have confirmed this in both Chrome (5.0.375) and Firefox (3.6.3).
When I use the ajax function to grab the remote content of some page, I would like to then apply jQuery selectors to that data. Does anyone know how this can be done? Let's say that I just grabbed the content from an html page. I would then like to be able to use a standard: $("#someID").val() to get the content of that page element.
I have a problem I have in my controller a function which poperly returns the value (i've checked by var_dump). When I try to access this data from $.ajax it returns nothing...
I'm currently working on a form where an entire HTML page is returned via the .ajax method. I would like to display only the content of the div with the id "content" (of the page returned) in the div with the id "result" (in the calling page). Here is my current script :
