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.

how to use ajax response data in another javascript

I am working with google map.My map data come from php using ajax response.
My ajax code:
<script type="text/javascript">
$.ajax({
type: "POST",
url: "mapajax.php",
dataType:'text',
success: function (result) {
console.log(result);
}
});
</script>
Now I have need to put my response data in my map var location
function initialize() {
var locations = [
//Now here I put my ajax response result
];
How can I do that?

You'll have to refactor your code a little. I'm assuming you call initialize from the success callback.
Pass the locations array as an argument to initialize.
function initialize(locations) { ... }
$.ajax({
type: "POST",
url: "mapajax.php",
dataType:'text',
success: function (result) {
initialize(result);
}
});
Then you can cut down even more and just do success: initialize, as long as initialize doesn't expect other parameters.

Here is a fiddle with an example using $.when but its for SYNTAX only not making the call
http://jsfiddle.net/2y6689mu/
// Returns a deferred object
function mapData(){ return $.ajax({
type: "POST",
url: "mapajax.php",
dataType:'text'
});
}
// This is the magic where it waits for the data to be resolved
$.when( mapData() ).then( initialize, errorHandler );
EDIT** function already returns a promise so you can just use
mapData().then()
per code-jaff comments

This is done using callbacks, http://recurial.com/programming/understanding-callback-functions-in-javascript/ , here's a link if you want to read up on those. Let's see your current code here:
<script type="text/javascript">
$.ajax({
type: "POST",
url: "mapajax.php",
dataType:'text',
success: function (result) {
console.log(result);
}
});
</script>
As you noticed, the 'result' data is accessible in the success function. So how do you get transport it to another function? You used console.log(result) to print the data to your console. And without realizing it, you almost solved the problem yourself.
Just call the initialize function inside the success function of the ajax call:
<script type="text/javascript">
$.ajax({
type: "POST",
url: "mapajax.php",
dataType:'text',
success: function (result) {
initialize(result);
}
});
</script>

Is expected dataType response from $.ajax() to mapajax.php call text ?
Try
$(function () {
function initialize(data) {
var locations = [
//Now here I put my ajax response result
];
// "put my ajax response result"
// utilizing `Array.prototype.push()`
locations.push(data);
// do stuff
// with `locations` data, e.g.,
return console.log(JSON.parse(locations));
};
$.ajax({
type: "POST",
url: "mapajax.php",
dataType: 'text',
success: function (result) {
initialize(result);
}
});
});

Making a AJAX request with jquery and parsing JSON

EDIT- I have figured out that the request is working correctly but I don't know what to do with the data once it has been retrieved from the server. I don't know how to access the JSON, how do I do this?
I am trying to do a jQuery AJAX request and parse the JSON which is hopefully received. Here is my code:
search.onsubmit = function() {
$.getJSON("http://www.geocodefarm.com/api/forward/json/d4abb1b19adb13e42eac5a7beac6f4dbeb4b4ba4/" + searchBox.value, function(data) {
var rawJSON = $.parseJSON(data);
alert(rawJSON.COORDINATES.latitude);
});
alert("test");
}
I known that the getJSON function is not working because the test alert appears. Why does it not work?

You can do it like so:
sendAjax: function (url, dataObj) {
$.ajax({
url: url,
type: "POST",
data: JSON.stringify(dataObj),
contentType: "application/json; charset=utf-8",
timeout: 30000,
success: function (result) {
//do shit..
}
,
error: function (result) {
}
});
}

Ajax function working in IE but not Firefox

I have an ajax function is called when a form is completed. It is suppose to redirect to a certain page if there is a success for a failure. When I run the form in IE, it works perfectly but in Firefox, the page does not redirect at all. It just refreshes the page. Here is the ajax code:
$.ajax({
url: "someURL",
type: "POST",
dataType: "xml",
data: params,
success: function () { window.location = 'success_page.htm' },
failure: function () { window.location = 'error_page.htm' }
});

Well, there's a minor mistake in your code: you are missing some semicolons:
$.ajax({
url: "someURL",
type: "POST",
dataType: "xml",
data: params,
success: function () { window.location = 'success_page.htm'; },
failure: function () { window.location = 'error_page.htm'; }
});
If this still doesn't resolve your problem, then I would guess there is something wrong with your params variable. Could you show us the whole code?

try
window.location = '/error_page.htm'
Sometimes working with IE I had the same problem, I use window.location.href instead of window.location

jQuery Ajax Call function

I want to be able to call a function from the "on success" region instead of having to place my code in that region. I'll be using the code twice so I'm trying to figure out how to place it outside of the jQuery.ajax() function.
Here is my current code:
$.ajax({
type: "GET",
url: "ws/getweather.ashx?zip=" + vZip,
dataType: "xml",
success: function (xml) {
$(xml).find('weather').each(function () {
// Load New Data
...
});
},
error: function (xml) {
alert("Unrecognized Region. Please try again.");
}
});
So instead of having...
function (xml) {
$(xml).find('weather').each(function () {
// Load New Data
...
});
I'd like to put the name of another function, and pass the xml to that function. That way I can have other events call the same set of code.
Thanks in advance!
UPDATE===================================================
Thanks to Mike Richards for his timely response. I'm including the exact syntax below because I had to add a few details to make it work...meaning, pass the XML to the other function.
$.ajax({
type: "GET",
url: "ws/getweather.ashx?zip=32751",
dataType: "xml",
success: function (xml){
weatherize(xml);
},
error: function (xml) {
alert("Unrecognized Region. Please try again.");
}
});
And then somwhere below, my other function
function weatherize(xml) {
$(xml).find('weather').each(function () {
// Load New Data
...
})
};

you can just pass in a function for that parameter :)
success : successFunction,
and then, somehwere else:
function successFunction(data) {
// Do Something
}
