Javascript get JSON value from URL error

im using the function below to get image names. I also use the json code to get data of a different url, but somehow it isnt working at this. (im new to javascript. Just writing php normally.
function getImgname(name) {
$.getJSON("http://url.com/info.php?name="+name, function(json321) {
return json321.js_skininfo;
});
}

Try this:
function getImgname(myName) {
$.ajax({
url: 'http://url.com/info.php',
data: {
name: myName
},
type: 'POST',
dataType: 'json',
success: function(data) {
// do what you want with your data
return data.js_skininfo;
}
});
}

I tried this now:
function getImgname(myName) {
$.ajax({
url: "http://url.com/ninfo.php",
type: 'POST',
dataType: 'json',
success: function (data) {
return data.js_skininfo;
},
error: function () {
}
});
}
This isnt working (undefinied), but if i alert the data.js_skininfo it shows me the correct value.

not able to pass value using ajax in php file

I am not able to pass value using ajax in php file.
Corrected Code
<script>
$("body").on('change', '#area', function () {
//get the selected value
var selectedValue = $(this).val();
//make the ajax call
$.ajax({
url: 'box.php',
type: 'POST',
data: {option: selectedValue},
success: function () {
console.log("Data sent!");
}
});
});
</script>
here the php code
<?php $val=$_POST['option'];echo $val; ?>

There are a few problems here:
It should be url, not rl. Also, you have type: POST' with it ending in a ', but no starting '.
It should be type: 'POST'.
It should then look like this:
$("body").on('change', '#area', function() {
var selectedValue = this.value;
$.ajax({
url: 'box.php',
type: 'POST',
data: {
option : selectedValue
},
success: function() {
console.log("Data sent!");
}
});
});
If you want to view your data on the same page after (as on box.php, you are echo'ing the value.), you can do this:
success: function(data) {
console.log(data);
}
This will then write in the console what option is, which is the value of #area.

Try the following code
$("body").on('change',function(){
$.ajax({
URL:<you absolute url>,
TYPE:POST,
Data:"variable="+$("#area").val(),
Success:function(msg){
<do something>
}
});
});
Hope this will help you in solving your problem.

Your just miss ajax method parameter spelling of 'url' and single quote before value of type i.e. 'POST'. It should be like
$.ajax({
url: 'box.php',
type: 'POST',
data: {option : selectedValue},
success: function() { console.log("Data sent!");}
});

Calling Ajax request function in href

I have an href in an html page and i have an AJAX request in a method in a javascript file.
When clicking on href i want to call the JS function and I am treating the response to add it to the second html page which will appear
function miniReport(){
alert('TEST');
var client_account_number = localStorage.getItem("numb");
var request = $.ajax({
url: server_url + '/ws_report',
timeout:30000,
type: "POST",
data: {client_language: client_language, PIN_code:pin,client_phone:number}
});
request.done(function(msg) {
//alert(JSON.stringify(msg));
});
if (msg.ws_resultat.result_ok==true)
{
alert('success!');
window.open("account_details.html");
}
request.error(function(jqXHR, textStatus)
{
//MESSAGE
});
}
I tried with , and also to write the function with $('#idOfHref').click(function(){}); not working.
All I can see is the alert TEST and then nothing happens. I checked several posts here but nothing works for me.

Function can be corrected as,
function miniReport(){
alert('TEST');
var client_account_number = localStorage.getItem("numb");
$.ajax({
url: server_url + '/ws_report',
timeout:30000,
type: "POST",
data: {"client_language": client_language, "PIN_code":pin,"client_phone":number},
success : function(msg) {
//alert(JSON.stringify(msg));
if (msg.ws_resultat.result_ok == true)
{
alert('success!');
window.open("account_details.html");
}
},
error: function(jqXHR, textStatus)
{
alert('Error Occured'); //MESSAGE
}
}
});
1. No need to assign ajax call to a variable,
2. Your further work should be in Success part of AJAX request, as shown above.

It's a bad practice use an onclick() so the proper way to do this is:
Fiddle
$(document).ready(function(){
$('#mylink').on('click', function(){
alert('onclick is working.');
miniReport(); //Your function
});
});
function miniReport(){
var client_account_number = localStorage.getItem('numb');
$.ajax({
url: server_url + '/ws_report',
timeout:30000,
type: "POST",
data: {
'client_language': client_language,
'PIN_code': pin,
'client_phone': number
},
success: function(msg){
if (msg.ws_resultat.result_ok==true)
{
alert('success!');
window.open("account_details.html");
}
},
error: function(jqXHR, textStatus)
{
//Manage your error.
}
});
}
Also you have some mistakes in your ajax request. So I hope it's helps.

Rectified version of your code with document .ready
$(document).ready(function(){
$("#hrefid").click(function(){ // your anchor tag id if not assign any id
var client_account_number = localStorage.getItem("numb");
$.ajax({
url: server_url + '/ws_report',
timeout:30000,
type: "POST",
data:{"client_language":client_language,"PIN_code":pin,"client_phone":number},
success : function(msg) {
if (msg.ws_resultat.result_ok == true)
{
window.open("account_details.html");
}
else
{
alert('some thing went wrong, plz try again');
}
}
}
});
});

Uncaught SyntaxError: Unexpected token :

i have an unexpected token :
but i dont know why this is.
the code where it is happening.
<script type="text/javascript">
$('.delete-btn').click(function() {
$.ajax(function() {
type: 'POST',
url: 'ajax.php',
data: { filename: filename },
success: function(return) {
if(return == 'SUCCESS') {
$this = $(this).closest('tr');
$this.remove();
}
}
});
});
</script>
I hope someone can find why i get the unexpeded token : at the url: 'ajax.php', rule.

The syntax error is in your success callback. You've named the argument return, which is a reserved word. Call it something else.
Niet here, merging my answer into this one to complete the picture:
Change:
$.ajax(function() {
To:
$.ajax({
Pay closer attention to what you're writing :p

return is a reserved word in JavaScript. Use any other name other than return. I have used data instead of return. Also there is type is an error in ajax function you have written. updated the same. Use the below code
<script type="text/javascript">
$('.delete-btn').click(function() {
$.ajax({
type: 'POST',
url: 'ajax.php',
data: { filename: filename },
success: function(data) {
if(data == 'SUCCESS') {
$this = $(this).closest('tr');
$this.remove();
}
}
});
});
</script>

return is a keyword at javascript dont use it as a variable name
<script type="text/javascript">
$('.delete-btn').click(function() {
$.ajax(function() {
type: 'POST',
url: 'ajax.php',
data: { filename: filename },
success: function(data) {
if(data== 'SUCCESS') {
$this = $(this).closest('tr');
$this.remove();
}
}
});
});
</script>

Variable not working in simple Ajax post

Can't seem to get the variable getID to work. I'm trying to change the html of the div. I know that the variable has the right value.
$('.cardid').change(function() {
var getID = $(this).attr('value');
$.ajax({
type: "POST",
url: "inc/change_thumbnail.php",
data: "id="+getID,
cache: false,
success: function(data) {
$("#"+getID).html(data);
alert("success");
},
error: function (err) {
alert("error");
}
});
});

Write data in $.ajax as data: {id : getID}, instead of data: "id="+getID,

Use val to get the value of an input :
var getID = $(this).val();
As you're making a POST request, you should also use the data argument to let jQuery properly send the value :
$.ajax({
type: "POST",
url: "inc/change_thumbnail.php",
data: {id:getID},
cache: false,
success: function(data) {
$("#"+getID).html(data);
alert("success");
},
error: function (err) {
alert("error");
}
});

You can try this:
$('[id="'+getID+'"]').html(data);
and yes you should pass it this way:
data:{id:getID}
