I'm grabbing an update from a json file, but I want to have it update perodically to the screen, overwriting what it found before... sort of like Prototype's Ajax Updater. Is this possible in Jquery? I scoured the groups to but only found a digg spy thing, which is sort of what I'm looking for but it was dated for 2007, so there's gotta be something new or is that it?
View 1 Repliesi am trying to make the contents of one drop-down box dependent on the
contents of another using AJAX (prototype.js) and PHP
I have it working so that a new dropdown appears when i select a value
in the first dropdown:
<?php echo $html->selectTag('Review/cruiseline', $cruise_lines, null,
array('onchange'=>'new Ajax.Updater('test', 'ships?variable=12',
{ method: 'get' }, {asynchronous:true, evalScripts:true});'), null,
true, false);?>
In my php script (which is located at URL 'ships'), I am just getting
the value of 'variable' from the $_GET super global but I obviously
want that value to be dynamic and equal to the value selected in the
dropdown.
So the missing piece is passing the selected dropdown value from
HTML / Javascript to PHP. Anyone know how to do that?
I wanna make a live-error-checking sign up form.
So these are the codes
this is the php file which return echos to the js files (there's no error here, I've posted this so you know what it's all about) [code]...
if a user writes in the text box for nickname a nickname that is already registred then in a text box near the input text it will appear something like : "This Login name is already taken!"
and so on for every field (firstname, lastname...)
I have done this previously with classic ajax tehnics (that with onreadystatechanged) and it worked. But this version does not. Can you spot the error here?
I'm using the prototpye libary (the version is 1.4.0) and i can't seem to get my ajax updater to work. Could anyone help please?
HTML Code:
function content(page){
new Ajax.Updater("contentDiv", "content.php", {
parameters : "page="+page,
onFailure : window.document.href = "http://kieranpeat.co.uk/gg/?page="+page
});
};
HTML Code:
<a href="?page=pictures" onclick="content('pictures');return false;" title="Goto the my pictures section">My Pictures</a><br />
How I can convert a string to a json array.
start code:
The problem is that .css treats snip[1] as a string but I need it to handle it as a json array.
Bad: .css
Good: .css
I have a html file that I want to load, loop through the json data and for each json entry I want to add a new block of the html and insert the json data into the matching div/class of the html. json looks like this:
{"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
html looks like this:
<div class="Name"></div><div class="Age"></div>
So for each json entry of name/age, I want to insert that into the html, and then add another row, until all json data has been fetched. After this I want to insert all of this into #box, which is just a divthat should contain that html. Looping like this obviously does not work, since I just keep replacing the same html through the loop.
var jsonData = {"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
$.each(json.Super, function() {
$('#box .Name').html(this.Name);
$('#box .Age).html(this.Age);
});
I have a JSON structure in API.When I call the API in my code it returns as the same JSON .I have to print this JSON result as table with pagination in Javascript. The table should be dynamic with previous and next buttons and the table should populate the results according to the JSON and each page should have 20 entries and then the remaining entries should go on the next page and I should be able to go back and forth in the table using previous and next respectively.tell me the exact code of how to start with getting JSON from the API and then write the JSON data in the form of dynamic table with pagination.

no longer work with the addition of 1.5.Looking at firebug, the correct data is returned, but the function breaks after entering the callback.Everything simply stops.I read about the changes to Ajax call in 1.5, but I have over a thousand such calls through my project -> I cannot even begin to think about hunting them all down and changing them, let alone bug testing it all.
Using json to gather some data. Here's abridged version:
var ids = new Array(1,2,3,4,5,6,7);
for(var i=0;i<ids.length;i++) {
var site = '/ajax/get_feed' + '/<?=isset($dashboard) ? $dashboard : ''?>/' + ids[i];
var divID = ids[i];
getJSON(site, divID);

I remove the ajax loader image, then append data.result, where result is an html string. I want to animate the new content... I've never done something like the following,
$('#twitter img.ajaxloader').fadeOut(); $('#twitter').addClass('lefttext').append(data.result).fadeIn('slow'); I know this doesn't work. Essentially what I'd love to see is for my $('div.row') (the html string returned is wrapped inside a div with a class='row') to animate much like an accordion does when it opens. Just not sure how to get there.
I am having difficulty displaying a specific key from a json file. I am trying to parse the following json file using query:
[URL]
I am using this type of function to parse the data:
$.each(json.route,function(i,route){
<!--add a paragraph tag to the results div and enter the speficied key-->
$("#results").append('<p>Result: '+ route +'</p>');
Using this I am able to print all the keys from the route but I am not able to print a specific key.
What I want to do is just get the results for the key "fuelUsed" using this method:
$("#results").append('<p>Result: '+ route.fuelUsed+'</p>');
But I never get back any data that way. Am I not specifying my key correctly?

Do you need to use a .json file when using .getJSON? I simply want to print data from my select.php file that has an json encoded array. If there is a more simple way to do this without using json encode
How can I get the json that this url generates?[URL]... It returns a json object as a file to download, I've tried getting the data as jsonp, but it needs a callback in the feed, but I can't generate it cause the server which generates the code is external.

Couldnt make it work using the get method. And using other data type just would make the incoming data as null (even including ?callback=? in the url).

View 10 Replies View RelatedIn addition to fetching JSON you might want to POST it back to the server, but there is no postJSON method. You cannot use the generic ajax method, either. What is missing is the complement of "eval" to turn a JavaScript object in to JSON. The JSON.stringify function from www.json.org (see json2.js in JavaScript section) does the trick, but it would be nice if jQuery incorporated that out of the box, to save some hunting time.
Using the jquery ajax method to set the "type" to "json" and the "content-type" to "application/json" send and recieve JSON, but you must use JSON.stringify to convert your outgoing object to JSON. P.S.. a lot of forgiving parsers have resulted in a lot of articles on JSON being wrong. would I like to mention that here. Property names are JSON strings. JSON strings have double quotes. Therefore, property names have to be surrounded with double quotes. Single quotes are not JSON strings and not legal (JSON is not JavaScript).

I use $.getJSON for all my ajax stuff and it works beautifully but there is one particular situation where I use an iframe hack to do an ajax file upload and even though the returned value is a json object (created with PHP), jQuery treats it like a string. I'm using json2.js right now and it does the trick but I don't like including that much extra code because of one rare situation. So my question is, be it with $.getJSON or by specifying 'json' as the expected return type of an ajax request, jQuery *seems* to be able to convert into json. The string returned is already a json object, I just need jQuery to be able to treat it like one. I've tried wrapping it in a jQuery object but no use. (and I really don't want to go down the eval() path)...
