I am doing a project now i going to use ajax to retrieve coordinate from the json in html and pin the coordinate onto a point on the map using javascript but the problem is i am only able to use one point on the map can tell me what to add in ? or how should i change it with? it will be nice if u can change the code from the below and show me how
Quote:
so, the pseudo code: - on change of input contents, check to see if two input fields are set - if set, update a third field with "loading..." text and a loading gif - use ajax to send data to a url, and get a calculated json response - update the third field with the calculated response
I know I'm getting the correct response, according to firebug: {"pace":"10:00"}
the code:
$('#run_distance').change(function() {
if ($(this).val() != '' && $('#run_time').val() != '')
{
$('#run_pace').val('Calculating Pace…');
[Code].....
how to update the #run_pace input field with the json response.
I am new to Ajax and have a bit of a gap in my understanding. I have a status monitor that sets a JS function to run every second with setInterval. When the document loads, I will need to get data from the server asynchronously (I wont know the info before hand) and use that data to set id values to find them as nodes and change them later on.
The problem is as I see it, that the callback function I will use to grab the initial data is coming back via a JSON object. The callback function is done with javascript. So, how can I take the JSON data, or converted to javascript data and set my ID values when the document loads? If I change the values dynamically with the DOM, will those values be reliable enough to use as my other recurring functions find them and set their innerHTML properties?
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);
});
What is the best way to server AJAX data and why? JSON, HTML, or XML? Which is best?
View 1 Replies View RelatedSo I can't for the life of me understand JSON. I've looked through numerous links but nothing. If I have a Database and all I want to pull is:
How do I print that out to an HTML document using JSON. I don't get it. I think it puts it in an array but how does it get there? Do I just print it out like I would a normal javascript array? If this isn't quite the right place to post this I apologize but there wasn't an AJAX section.
I have a web service that accepts application/json but returns HTML to place in a DIV. I am not having any luck configuring the .ajax call so that it both POSTs in a format accepted by the web service and does not attempt to validate the HTML response as JSON.
[Code]...
It would seem that I cannot have anything other than 'json' in the dataType, even though from the docs it appears that this only affects the interpretation of the response, changing it's value to 'html' causes the web service to reject the call. I've also tried a converter but perhaps I'm not using it properly. Is it possible to use jquery to post JSON and get back HTML? What configurations am I missing?
what i am trying to do is retrieve a json file from a link on a server and then edit it locally.How can i do this on javascript or ajax?

I have just started to learn about JQuery and wanted to learn how to retrieve data from an API.

Need info on retrieving a div from one html page and place it or its contents in another div? I'm trying to load tables from different pages into a div on this page. Tables are currently in divs with id-"table". The page I want to load them into also has a table in a div with id="table". I want to replace one table with other tables without leaving the page. That is, I am trying to prevent linking back and forth.
I've tried the following with no results;
xmlHttp.onreadystatechange=function() {
if(xmlHttp.readyState==4) {
divTable = document.getElementById("table").innerHTML=xmlHttp.responseText;
}}
xmlHttp.open("GET","../Menu/level9/menutable24.html",true);
xmlHttp.send(null);

View 2 Replies View RelatedI'm trying to use AJAX to load user's profile through a drop-down list on selected user. There are 3 seperate files:
1) view_info.php
2) selectuser.js
3) getuser.php
I tested and found that the value $q did pass from view_info -> selectuser.js -> getuser.php, and value changes correctly as i select different user from the drop-down list. Problem is, it simply can't fetch data from my database using the value $q. I tried debugging it for 3 hours already and is totally out of idea whats wrong with the script. i'm new to AJAX, this is my first script..

I have this code that load HTML tags (no including <html> or <body>)
into a DIV dinamically...
after correctly retrieving the HTML, I assign it to my DIV Container

textbox) contained in the dinamically loaded HTML
Once in my main document this, doesn't works:

not? How can I access this objects from my main page?

This question may appear opposite of most, but I'm learning JS using a book and I can't understand why/how this particular code works. I'm working on simply retrieving and passing information to and from html forms. This is a very simple script that will change what is selected in the drop down box depending on a button push.
Here is the script:
Code:
function flip(pizzatype) {
if (pizzatype.value == "Veggie Special") {
document.forms["pizzaform"].topping.value = "veggies";
} else if (pizzatype.value == "Meat Special") {
document.forms["pizzaform"].topping.value = "meat";
} else if (pizzatype.value == "Hawaiian") {
document.forms["pizzaform"].topping.value = "hampineapple";
}}
And here is the form's html:
Code:
<form id="pizzaform" action="#" onsubmit="return false;">
<p>
<input type="button" name="veggiespecial" onclick="flip(veggiespecial)"
value="Veggie Special"/>
<input type="button" onclick="flip(meatspecial)" name="meatspecial"
value="Meat Special" />
<input type="button" onclick="flip(hawaiian)" name="hawaiian"
value="Hawaiian" />
</p>
<p>Main Topping: <select name="topping">
<option value="cheese" selected="selected">Cheese</option>
<option value="veggies">Veggies</option>
<option value="meat">Meat</option>
<option value="hampineapple">Ham & Pineapples</option>
</select></p>
</form>
The way I see it is the button onclick will call the flip function and pass it a var, for example "veggiespecial". I understand the code that will perform the actual change on the drop down menu. What I don't understand is the if statement.
if(pizzatype.value == "veggiespecial")...
Shouldn't it be just (pizzatype == "veggiespecial")?
Why does it have to be pizzatype.value? Where the heck does the .value come from???
Anybody have a simple example of retrieving a page via ajax?
View 1 Replies View RelatedI'm trying to accomplish something unique that I am not finding any examples for in web searches.I have a webpage with arrow pictures that I will set up with a clickable link that will send http arguments to a php script.I need to grab the selected value in one of the drop down menus on that same page and send that as one of the html arguments when clicking on one of the arrow buttons.
Right now those drop down lists are just html form controls, would this all work together better if they were instead javascript drop down menus? I really want to build this page the best way for it to be built and I'm not afraid to make changes if there is a better way than what I'm using now.
I have an ajax script that I would like to use to retrieve a password hint from a database.Both the ajax script and the php retrieval script are stored on the same domain (we'll call it domain1.com), but the ajax script runs on another domain (domain2.com).All the scripts are working fine, individually, but when I try to integrate them, I'm getting a ready state of 4, but an HTTP status of 0. I've traced the code flow and the retrieval script is being called by the ajax script OK and it's echoing all the right stuff, but it's just not getting back to calling ajax routine.
I've read that an ajax routine can only call a script that resides on the same domain that it runs on. Is this correct and, if so, does anyone know of a work around, because I really need to be able to store the ajax script on domain1 and run it on domain2?If not, then can anyone suggest why I'm getting an HTTP status of 0, when all the individual components are working fine?

To make cross domain calls when json is required (JSONP) is easy
Code:
$.ajax({
url:"testserver.php",
dataType: 'JSONP',
success:function(json){
[Code]....
I see the XML comming in as a string argument of 'myCallback', but ist never called. Also 'success' is never called!

On hitting the button one new window is getting opened with response URL from 3rd party(in this case Google Checkout).
