I am having trouble sending JSON data to a server. Its definitely reaching the parser.php, but I am not what to create in PHP to fetch this data. Also I am not sure my Javascript is correct.
<SCRIPT>
var JSONObject = new Object;
JSONObject.description = "hello";
JSONstring = JSON.stringify(JSONObject);
runAjax(JSONstring);

I am trying to send the login info from a form into a IIS server and the asp file on the server will just respond back with the following text "Welcome, &name" on a ajax form on the client side. Currently, i am using a GET response and would like to send using JSON instead.
html file on client side

Is there any way I could fetch data from another web page?
Things like current weather, and rate of exchange?
I would search the data for example by
-loading a web page somehow (IFRAME?)
-going through all <td> tags in it and
-if the <td> had a spesific text, like "weather in Fooland" then
-I'd jump to the next <td> tag and take the text inside it, that hopefully had the data I was looking for.
I used an IFRAME to load a web page. It's id is called "myiframe"
var myIframe = document.getElementById("myiframe")
var iframeBody = myIframe.body;
var paragraphs = iframeBody.getElementsByTagName("p");
document.write(paragraphs.length); //this writes 0!
the page I loaded on the IFRAME has paragraph elements right on body. Why can't I find them?
I tried using node iterator (document.createNodeIterator() ? ) too, but that didn't work at all! I tried it without the IFRAME too. If you have any guesses what it might be, please tell me. Should it work in Mozilla? Should I create the node Iterator only after the page has finished loading?
I want that data against each option should be loaded as the option is selected in the combo box. As, while registering on yahoo, when we select a country all provinces of that country are loaded. (No need to click a submit button.)

how can I let the function that should check the message of the response know that 'msg' has been set?
Apologies if this is a fairly simple question! I'm fetching data (from a MySQL database), and would like to show an animated loading image while the data is being downloaded, and obviously then hide it when the data is fully downloaded. I've found plenty of tutorials describing how to achieve this is the other direction (i.e. when submitting a form) but I'm not sure how to adapt these to what I want.

View 3 Replies View RelatedI have my doubts if this question belongs to the javascript side since it's all good until the data from MySQL comes in, but since the javascript is the one breaking I'll take my chances.
The external js (portada.js)

var currentPosition = 0;

As you can see I have three divs with different slideshows (slideshow, slideshow2 and slideshow3), they have products that slide to the left. When I was testing to make sure it all looks good the sliding feature was working fine, but I lost this feature when the data was being retrieved from MySQL (at the moment on <div class="slide">).
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.

You can see in line 17 that it is no problem to show the fetched data from the other html-file in a div every 1 second.But I would like to change a picture dynamically.That means in detail:in the other html file stands either the value "0" or the value "1".This value should be fetched every 1 second (like the div-refresh) from the file.Then the value should be used as new src-name for the refreshing image, e.g.:fetched value = "1" => img src = "1.jpg" => [user can see a green light]fetched value = "0" => img src = "0.jpg" => [user can see a red light]How can I achieve this?
- How can I change the src name
- How can I refresh the image every 1 second with the new src name?
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 just started to learn about JQuery and wanted to learn how to retrieve data from an API.
I used the Flickr example provided here [url] and just changed the relevant code to point to the 500px api.
<body>
If I launch the following URL I do get the results properly [url]
Here's a sample of what the result looks like:-
I don't get any results when I run my code page. What am I doing wrong?
I'm trying to compare incoming JSON data to the existing data to see if there are any changes, but for giant objects like:
Code:
[{"date":"2011-09-03 23:06:03","notifier_id":"1","type":"1","unread":"0"},{"date":"2011-09-05 00:37:46"}]
if (JSON.stringify(oldData) == JSON.stringify(newData))
This doesn't seem to work. I've tried using:
Code:
escape("'" + JSON.stringify(W.notification.list + "'"))
but that ignores the objects properties and returns something like 22%5Bobject%20Object%5D%2C%5Bobject
whats the best way to pass a json string to the server.
if my jsonstring = {a:Ƈ',b:'sds',c:'sdg'}
could i send that to the server passing it as 1 variable like so:
url = /serverside.php?json=jsonstring
or would i have to break it down into something like this:
url = /serverside.php?a=1&b=sds&c=sdg
I need to use Jquery $.ajax() function in order to represent JSON objects in HTML page. JSONs are on a url: [URL]. That is a string of json objects.
View 1 Replies View RelatedI have this code:
var dataString = $.toJSON(data);
$.post(url, {dataValues: dataString}, function(res){
$('#secretIFrame').attr('src', url);
$('#secretIFrame').html(res);
});
Problem is, I can't access dataValues at the server side once I assign this same URL to the iframe.Is there any other way to POST JSON value through form submission without ajax? or any other way out, I am trying to download file that is based on some parameters and isn't a direct download link.
How does wrapping a json response from the server in textarea tags?
View 1 Replies View RelatedI am doing a password reset form using Jquery and PHP. If I try to submit an email id it should sent and email and report back the response text as success so that the user knows email has been sent. But I am stuck with JSON submit as I have an empty array to decode at the serverside. I am using minified version of json2.js from the official json.org website
Here is the code.
Code JavaScript:
var formdata = $("#log-box").serializeArray();
formdata = JSON.stringify(formdata);
var notifymsg;
alert(formdata);
$.ajax({
type: "POST",
url: "forgot-pass.php",
contentType: 'application/json',
data: formdata,
success: function(responsedata){
var some = responsedata.split("&");
$.each(some, function(index,value){
//alert("index="+index+"value="+value);
});
},
error: function(o, s, e){
alert("Form not posted
"+e);
}});
formdata alerted gives:
[{"name":"email","value":"ravi.k@gmail.com"},{"name":"acctype","value":"loginaccount"}]
PHP forgot-pass.php
Code PHP:
print_r($_POST);
Gives
Array(

The JSON string seems correct (I checked it with a validator) and it worked on an Ajax.updater (but i need a request now). Firefox keeps telling me:

The call always end up in the onFailure block. Full request here: [URL] It's very strange, Is there a better way to pass json objects to the server?
FYI, I am using jQuery 1.2.3, and the latest version of the jQuery Form plugin from URL...I am able to run the ColdFusion page on the server side to get the data, and Firebug is showing that I'm getting a response...but I'm unable to populate the JSON data into selected form fields on the page.I have two HTML forms; one for the user to input his/her ID number if available, and a longer form to collect more demographic info.Why is it not working? My forehead is getting bloody from banging it against this wall.
View 1 Replies View RelatedWhat i want to do is that this function post data to the server (ASP) and
the server will response with 'OK' My question is how can i send data clientside from Javascript to the server ? (navigate ? with url ?)
and check the returned data in the same function ?
function ShowData(TxtArt)
{
alert(TxtArt + ' : ' + parent.frames.Bottom.TxtUsrName.value + ' - ' +
parent.frames.Bottom.TxtRemarque.value); // testing purpose
// post the data to the server. ex .. myURL.asp?userID=1000&Art=ART1201
// fetch the data from the server. to verify if the 'OK' is recieved ->
the server will response with 'OK'
// if 'ok' -> i will update clientside an frame (ex. contents of
shoppingbasket)
}
Any idea's ?
I think I have a varialbe scope problem here, but I can't figure it out. What I'm trying to do is extract a piece of data from a JSON file using a variable established earlier in the script as one of the keys.
When I run this script I get the alert that lets me know that the variable "theMappableItem" has been established correctly. I click "OK" in the alert box. Then in my console (in firebug) I see a line showing that the .json file has been gotten successfully. Next in the console is an error that says:

The problem is that I'm trying to get value of a member item from JSON formatted string but it returns 'undefined'.
