  • JSON: How do I alert the name of the first node in level 1 in this code snippet?

    - by user143805
    var response = "{\"tree\":[{\"level1\":[{\"node\":{\"id\": 1,\"name\": \"paradox\",\"parent\": 0}}]},{\"level2\":[{\"node\":{\"id\": 2,\"name\": \"lucent\",\"parent\": 1}},{\"node\":{\"id\": 3,\"name\": \"reiso\",\"parent\": 1}}]},{\"level3\":[{\"node\":{\"id\": 4,\"name\": \"pessi\",\"parent\": 3}},{\"node\":{\"id\": 5,\"name\": \"misho\",\"parent\": 2}}]},{\"level4\":[{\"node\":{\"id\": 6,\"name\": \"hema\",\"parent\": 5}},{\"node\":{\"id\": 7,\"name\": \"iiyo\",\"parent\": 4}}]}]}"; var data = eval("(" + response + ")"); This is a dummy json response I am currently testing. Now how do I get the value of "name" in the 1st node of "level1" from the "tree"? Thanks

How can I avoid this behavior ? Thanks for your help !

  • Best way to manage JSON object via GET and POST in php.

    - by Kucebe
    My site does some short ajax call in JSON format, using jQuery. At client-side i'd like to send object just passing it in ajax function, without being forced to wrap it in an object literal like this: {'JSON_Obj' : myJSON_Obj }. For the same reasons, at server-side i'd like to manage objects without the binding of $_GET['JSON_Obj'] or $_POST['JSON_Obj']. For example, using file_get_contents("php://input"), i can manage POST requests in that way, but in GET format it doesn't work. Any suggestions?

  • drew's autoSuggest plugin help with AJAX results not showing

    - by s2xi
    hey guys, i use drew's autoSuggest plugin for some time but up until now I have hard coded my data into my JS, I'm trying to see if I can use AJAX to return the JSON data and query data like that. I seem to have it working but no matter what I try I can't get the results to be shown in the drop down UL it creates via jquery. The JSON comes back as it should. This is my PHP code: $input = $_GET["q"]; $data = array(); // query your DataBase here looking for a match to $input $query = mysql_query("SELECT `state`, `idStates` FROM `states_list` WHERE (`state` LIKE '%{$input}%' OR `abbr` LIKE '%{$input}%')"); while ($row = mysql_fetch_assoc($query)) { $json = array(); $json['value'] = $row['idStates']; $json['name'] = $row['state']; $data[] = $json; } header("Content-type: application/json"); echo json_encode($data); and my JS: $('#state').autoSuggest('resources/ajax/suggest.php', {matchCase: true, minChars: 2, startText: '', emptyText: '', retrieveComplete: function(data){ console.log(data.value) }}); I have been trying to debug so I added the retrieveComplete parameter in there for that. the PHP returns the AJAX with the JSON content...now just to figure out how to get the JS to pick it up append it to the UL LI UPDATE: I appened the data to a test div and its returning results:[object Object],[object Object],[object Object]

  • Ajax -- re-load div on success.

    - by RPM
    I am trying to accomplish a "re-load." More specifically, I need to be able to refresh a portion of my page as a result of another successful ajax call. Moreover, I load my portion of the page via ajax which obtains it's content from an ajax post. The result is my content being displayed inside my portion precisely. I need this portion of the page refreshed after a successful ajax post. Here is some of the code: /* Ajax-- this part is loaded automatically, and I need it reloaded upon success of another ajax post. This data comes from the outcome of my other ajax function. */ $('#newCo').load('click', function() { $.ajax({ url: 'index.php?dkd432k=uBus/310/Indeed', dataType: 'json', success: function(json) { if (json['newCompare']) { $('#newCo .newResults').html(json['newCompare']); } } }); }); The next portion of code is responsible for posting the data of which I obtain in this above ajax function. function ZgHiapud (ofWhich) { $.ajax({ url: 'index.php?dkd432k=uBus/310/update', type: 'post', data: 'product_id=' + product_id, dataType: 'json', success: function(json) { $('.success, .warning, .attention, .information').remove(); if (json['success']) { $('.attention').fadeIn('slow'); $('#compare_total').html(json['total']); $('html, body').animate({ scrollTop: 0 }, 'slow'); } } }); } In the end, I need to obtain the data that I send to the server immediately upon success of the second ajax call. This data that is sent via the second ajax call needs to fire the first ajax call upon success.

  • Cannot access NSDictionary

    - by michael blaize
    I created a JSON using a PHP script. I am reading the JSON and can see that the data has been correctly read. However, when it comes to access the objects I get unrecognized selector sent to instance... Cannot seem to find why that is after too many hours !!!! Any help would be great ! My code looks like that: `NSDictionary *json = [[NSDictionary alloc] init]; json = [NSJSONSerialization JSONObjectWithData:receivedData options:kNilOptions error:&error]; NSLog(@"raw json = %@,%@",json,error); NSMutableArray *name = [[NSMutableArray alloc] init]; [name addObjectsFromArray: [json objectForKey:@"name"]];` The code crashes when reaching the last line above. The output like this: raw json = ( { category = vacancies; link = "http://blablabla.com"; name = "name 111111"; tagline = "tagline 111111"; }, { category = vacancies; link = "http://blobloblo.com"; name = "name 222222222"; tagline = "tagline 222222222"; } ),(null) 2012-06-23 21:46:57.539 Wind expert[4302:15203] -[__NSCFArray objectForKey:]: unrecognized selector sent to instance 0xdcfb970 HELP !!!

  • IE AJAX/Jquery issue - redirecting to new page instead of loading it into a div

    - by phx-zs
    I have a page like this: <form class="ajax" method="post" action="add_item.php"> [text input] [submit button] </form> [list any items the user has in a div here called #items] When the user clicks the submit button, a function like this is called: $("form.ajax").live('submit', function(event) { params = $(this).serialize(); $.post($(this).attr("action"), params, function(data){ json = $.parseJSON(data); // do stuff based on the json results if(json.success.action == 'replace'){ $(json.success.container).html(json.success.message); } else{ $(json.success.container).prepend(json.success.message); $(json.success.container).find(".item:first").slideDown(); } }); event.returnValue = false; return false; }); This is supposed to load add_item.php into the #items div, and it works fine in FF, Chrome, Safari, just not IE. In IE (tested 7 and 8) when I click Submit it redirects the page to add_item.php rather than loading it into the #items div. I tried adding event.preventDefault(); to the end of the function but that didn't work. Any ideas?
