HTTP get requests in ajax

I am pretty new to javascript where I am trying with ajax to make an get request. I am trying to get the password from the response.
Javascript code:
$(document).ready(function () {
$("#LoginUser").click(function () {
$.ajax({
url: 'http://website/api/user/Mikkel1337',
dataType: 'json',
type: 'GET',
contentType: 'application/json',
error: function () {
alert("An error had occurred");
},
success: function (data) {
var jsonStr = JSON.stringify(data);
alert(jsonStr['password']);
}
});
});
})
The response JSON code looks like this:
{"userId":16,"firstName":"mojn","lastName":"mojn","email":"mojn#mojn.dk","accountName":"Mikkel1337","password":"123","userRoleId":1,"active":false,"userRole":null,"competetion":[],"judge":[],"team":[]}
When im running this I only get the error function. Any suggestions or solution is appreciated :)

Basically you are converting the JSON to string and trying to access the string as object. Please don't stringify the data, and for JSON why using long code, your code should be:
$(document).ready(function () {
$("#LoginUser").click(function () {
$.getJSON( "http://website/api/user/Mikkel1337", function( data ) {
// do something on success
alert(data.password);
});
});
});
Cheers !!!

dont need to JSON.stringify of data simple use
$(document).ready(function () {
$("#LoginUser").click(function () {
$.ajax({
url: 'http://website/api/user/Mikkel1337',
dataType: 'json',
type: 'GET',
contentType: 'application/json',
error: function () {
alert("An error had occurred");
},
success: function (data) {
alert(data.password);
}
});
});
})

You should pass two argument for error:function(jqXHR, exception) as below.
And check once your API Url using proper way, may be your API is not show you proper result and you not get any of data from that API so that may be a reason you get error message.
$(document).ready(function () {
$("#LoginUser").click(function () {
$.ajax({
url: 'http://website/api/user/Mikkel1337',
dataType: 'json',
type: 'GET',
contentType: 'application/json',
success: function (data) {
var jsonStr = JSON.stringify(data);
//also try this way to get JSON data:
// var jsonStr =JSON.parse(data);
alert(jsonStr['password']);
},
error: function (jqXHR, exception) {
alert("An error had occurred");
},
});
});
});

how to execute a javascript function returned from ajax response

I have a function which i want to execute when ajax makes a successful request but it doesn't execute here my jquery part
$.ajax({
type: "POST",
url: "https://www.example.com/create_chat.php",
data: dataString,
beforeSend: function()
{
$("#loading_indicator").show();
},
success: function(response)
{
$(".example").html(response);
}
});
here is the response from php file
<script>start_chat(); alert("testing");</script>
i tried adding this also
$(".example").find("script").each(function(i) {
eval($(this).text());
});
but nothing works

Your response from create_chat could indicate which function will be used. For example
$.ajax({
type: "POST",
url: "https://www.example.com/create_chat.php",
data: {
dataString: dataString
},
beforeSend: function()
{
$("#loading_indicator").show();
},
success: function(response) // response could be 1,2,3,4.. etc
{
if(response==1) {
start_chat();
}
if(response==2) {
stop_chat();
}
if(response==3) {
change_chat_room();
}
...
$(".example").html(response);
}
});

While there are work arounds, you should never be executing the response of an Ajax call directly.
"Scripts in the resulting document tree will not be executed,
resources referenced will not be loaded and no associated XSLT will be
applied."
http://www.w3.org/TR/XMLHttpRequest/#document-response-entity-body
Best practice is to respond with data, typically in the form of JSON, JSONP or HTML.

Try This,
$.ajax({
type: "POST",
data: {
'dataString': dataString
},
url: 'https://www.example.com/create_chat.php',
success: function(data) {
start_chat();
alert('Success');
},
error: function(data) {
alert('failed');
}
});

Ajax request not working when a function is added to the success option

I am having trouble getting an ajax GET request (or any request for that matter) to retrieve the response. I am simply trying to return the response in an alert event:
<script>
$(document).ready(function() {
$('#test').click(function() {
$.ajax ({
type: 'Get',
url: 'https://crm.zoho.com/crm/private/json/Potentials/searchRecords?authtoken=XXX&scope=crmapi&criteria=(((Potential Email:test#email.com))&selectColumns=Potentials(Potential Name)&fromIndex=1&toIndex=1',
dataType: 'json',
success: function(data) {
alert(data);
}
});
});
});
</script>
I can get this and other similar post requests to work by taking away the function in the success option and editing the code like this:
<script>
$(document).ready(function() {
$('#test').click(function() {
$.ajax ({
type: 'Get',
url: 'https://crm.zoho.com/crm/private/json/Potentials/searchRecords?authtoken=XXXX&scope=crmapi&criteria=(((Potential Email:test#email.com))&selectColumns=Potentials(Potential Name)&fromIndex=1&toIndex=1',
dataType: 'json',
success: alert('success')
});
});
});
</script>
Why is this? And more importantly, how can I retrieve the response data and transfer it to an alert message? Any help is appreciated!
** Update:
Upon reading the first two users' responses on this question, this is what I have:
<script>
$(document).ready(function() {
$('#test').click(function() {
$.ajax ({
type: 'GET',
url: 'https://crm.zoho.com/crm/private/json/Potentials/searchRecords?authtoken=418431ea64141079860d96c85ee41916&scope=crmapi&criteria=(((Potential%20Email:test#email.com))&selectColumns=Potentials(Potential%20Name)&fromIndex=1&toIndex=1',
dataType: 'json',
success: function(data) {
alert(JSON.stringify(data));
},
error: function(data) {
alert(JSON.stringify(data));
}
});
});
});
</script>
I am able to get the error response, so I can confirm there is some kind of error. I also want to point out that I am making the request from a different domain (not crm.zoho.com) so should I be using jsonp? If so, how would I alter the code?

When you have
success: alert('success')
you do NOT have a successful request, you are actually executing this function at the start of AJAX method. The success parameter requires a pointer to a function, and when you use alert('success') you are executing a function instead of providing a pointer to it.
First thing that you need to try is to update type to GET instead of Get:
$.ajax ({
type: 'GET',

Try using the .done() function as follows:
<script>
$(document).ready(function() {
$('#test').click(function() {
$.ajax ({
type: 'Get',
url: 'yourUrl',
dataType: 'json',
}
}).done(function(result) {alert(data);}) //try adding:
.error(function(jqXHR, textStatus, errorThrown) {
console.log(textStatus, errorThrown);})
});
});
the error function will also give you some information in your console as to the status of your request.

Ajax Get Request with JQuery Error

I'm trying to call a php script with a get request and using the data theaddress however the results are showing me the source of the page im calling.
The page im calling is here
Here is my ajax function that will get this page
$( document ).ready(function() {
var address = document.getElementById("address");
$.ajax({
url: '/r10database/checkSystem/ManorWPG.php',
type: 'GET',
data: 'theaddress='+address.value,
cache: false,
success: function(output)
{
alert('success, server says '+output);
}, error: function()
{
alert('Something went wrong, saving system failed');
}
});
});

$( document ).ready(function() {
var address = document.getElementById("address");
$.ajax({
url: '/r10database/checkSystem/ManorWPG.php',
type: 'GET',
data: 'theaddress='+address.value,
cache: false,
success: function(output)
{
alert('success, server says '+output);
}, error: function(error)
{
alert (error); // this is the change from the question
}
});
});

Put the dataType as json with a curly brace
data: {theaddress:address.value},
dataType:'json',
success: function(output)
{
alert('success, server says '+output);
}, error: function(xhr)
{
alert (xhr.status);
}
and get the data in ManorWPG.php as $_GET['theaddress']
** share the xhr.status if failed.

Calling a PHP script using ajax

hi i am calling a php file using ajax after an interval of time. In my php file i simply echo a text line. But it didnt show me any output after time interval..
here is my ajax code form where i am calling my php file..
<script>
$(document).ready(function() {
setTimeout(function() {
$.ajax({
url: 'process.php',
type: 'post',
data: {"token": "your_token"}, });
}, 5000);
});
</script>
code inside the process.php file
<?php
echo "hello testing";
?>

You aren't handling the response from php script. You need to get it by success parameter in ajax. Try this:
$(document).ready(function() {
setTimeout(function() {
$.ajax({
url: 'process.php',
type: 'post',
data: 'x=1&y=2', // data here! use query strings like this or;
// data: { x: '1', y: '2' }
success: function(response) { alert(response); } // alert the response text
// returns 'hello testing'
error: function(){ alert('error while posting data'); }
});
}, 5000);
});

User the success and error function of ajax. for eg
$.ajax ({
url: 'process.php',
type:'post'
data:data1,
success: function (response) {
//alert response here you will get the value hello testing
alert (response);
},
error {
alert ('error');
}
});

You should modify your code to use the response.
<script>
$(document).ready(function() {
setTimeout(function() {
$.ajax({
url: 'process.php',
type: 'post',
data: {"token": "your_token"},
success:function(str){
$("#YOUR_ELEMENT").html(str);
}
});
}, 5000);
});

Just change your JQuery script to show the response after successful request it can be done with done() or success functions.
<script>
$(document).ready(function() {
setTimeout(function() {
$.ajax({
url: 'process.php',
type: 'post',
data: { token: "your_token"}}).done(function(msg){
$("#response").append(msg);
};
}, 5000);
});
This will append reponses to #response every 5s when ajax request is successful.

the success block, which handles the data returned from remote script is present in your code. you may need to add something like this .
JS CODE:
$(document).ready(function() {
setTimeout(function() {
$.ajax({
url: 'process.php',
type: 'post',
data: {"token": "your_token"},
}).done(function( data) {
//data received from remote script
});
}, 5000);
});
Happy Coding :)

Timeout is not the culprit here.
We need to make sure that you have a server where process.php resides and its running fine.
Make sure the path for the file process.php is right. You can use browser's developer tools. When the request is made you will see a new entry under "Network" tab of the developer tools. Exploring it you can get the url at which it the file should be available.
I would suggest using Google Chrome's "postman" extension to test the ajax call before implementing it in your code.
Also you need to have a callback that will run in case of request success or failure. Once you get the string in success response, you can do whatever you intend to do with it.
<script>
$(document).ready(function() {
setTimeout(function() {
$.ajax({
url: 'process.php',
type: 'post',
data: {"token": "your_token"} //removed the comma from last argument
}).done(function(serverResponse) {
alert( "Success: " + serverResponse ); //Will show success alert with concatenated text string if the request is successful
}).fail(function(serverResponse) {
alert( "Error: " + serverResponse.message); //Will show error alert with concatenated error message
});
}, 5000);
});
</script>

the php page sends the string "hello testing", and you have to manage it.
take a look here for an example: click me
