Unknown error using AJAX to stay in the same page

Following this previous link, I tried a new AJAX code, but still getting the same result (Data is inserted correctly, but can't stay in the same page).
$(function(){
$("#form1").on("submit", function(e){
$.ajax({
url: 'insert.php',
type: 'post',
data: $('#form1').serialize(),
dataType: 'json',
success: function(data) {
alert($('#form1').serialize());
});
e.preventDefault();
});
});
The form has an id="form1" and submit button inside this form is id="insert".
Any help is appreciated, need to fix this today.

The success function should be closed before closing AJAX function. You forgot to add a closing }:
$(function(){
$("#form1").on("submit", function(e){
$.ajax({
url: 'insert.php',
type: 'post',
data: $('#form1').serialize(),
dataType: 'json',
success: function(data) {
alert($('#form1').serialize() + "&insert=yes"); // add this
} //<--------------------------------------- You missed this
});
e.preventDefault();
});
});
You are sending the insert key as a parameter to post, but it doesn't work because you are not adding it while sending to AJAX. So add that and it works.

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 redirect on error

I'm calling php file through ajax call and if it returns nothing i want to redirect user to another page (It's for error reports, if it doesn't return anything it means that user logged in). Tried to add error section but it doesn't work. Any suggestions will help. Thanks! Btw, I have small jQuery function at the top of the ajax function, why it breaks my whole ajax call?
ajax.js
function loginAjax() {
//$("#email_errors").empty(); //This function doesnt work and kills whole ajax call. Here is loginAjax function call line - <button type = "submit" id = "push_button" onclick = "loginAjax(); return false">PushMe</button>
$.ajax({
url: "Classes/call_methods_login.php",
type: "POST",
dataType: "json",
data: {
login_email: $("#login_email").val(),
login_password: $("#login_password").val(),
},
success: function(data) {
$("#login_error").html(data.login_message);
}
});
}

$.ajax({
url: "Classes/call_methods_login.php",
type: "POST",
dataType: "json",
data: {
login_email: $("#login_email").val(),
login_password: $("#login_password").val(),
},
success: function(data) {
$("#login_error").html(data.login_message);
},
error: function(){
window.location.replace("http://stackoverflow.com");
}
});
}

To redirect using javascript all you need to do is override the location.href attribute.
function loginAjax() {
$.ajax({
url: "Classes/call_methods_login.php",
type: "POST",
dataType: "json",
data: {
login_email: $("#login_email").val(),
login_password: $("#login_password").val(),
},
// the success method is deprecated in favor of done.
done: function(data) {
$("#login_error").html(data.login_message);
},
fail: function(data) {
location.href="path/to/error/page";
}
});
}

Display loading while retrieving data using Ajax method

I am using ajax, sometimes it takes time to load all the data from my database therefore I need to find a way to display (Loading...) While the data is not yet complete. Below is my sample code, and I am looking for some event while the data is still in process.
$.ajax({
type: "POST",
url: "some.php",
data: "name=John&location=Boston",
success: function(data){
$('#para').html(data);
}
});

It is very simple..
before you call the ajax start your loading image..& after the success hide the image
for eg :
$.fancybox.showLoading();
$.ajax({
type: "POST",
url: "some.php",
data: "name=John&location=Boston",
success: function(data){
$.fancybox.hideLoading();
$('#para').html(data);
}
});
here
$.fancybox.showLoading()
is my function in which I have the property of displaying the loader,

This will be internally called whenever an ajax call is made.
$.ajaxStart(function() {
$("img#loading").show();
});
$.ajaxComplete(function() {
$("img#loading").hide();
});
HTML
<img src="../images/loading.gif" alt="wait" id="loading"/>

<div id="loading">LOADING...</div>
var loading = $("#loading");
loading.hide();
function doAjax() {
loading.show();
$.ajax({
url: "/js/beautifier.js",
success: function (data) {
loading.hide();
}
});
}
doAjax();

Loading gif image while jQuery ajax is running

I am trying to show a loading image while my ajax call is running, however using the beforeSend attribute is not changing my result area.
$.ajax({
url: "/answer_checker.php",
global: false, type: "POST",
data: ({...clipped...}),
cache: false,
beforeSend: function() {
$('#response').text('Loading...');
},
success: function(html) {
$('#response').html(html);
}
}
Thanks in advance.

I had a similar problem. To resolve my issue, I replaced the .text, in the beforeSend section, with .html and created a html tag to insert into the element that holds my status. The success function did not replaced the content created by the .text() function but it did replace content created by the .html() function.
$.ajax({
url: "/answer_checker.php",
global: false, type: "POST",
data: ({...clipped...}),
cache: false,
beforeSend: function() {
$('#response').html("<img src='/images/loading.gif' />");
},
success: function(html) {
$('#response').html(html);
}
}

I have a solution, it may not be the best way to do it but it has worked in this case.
$('input').keyup(function () {
$('#response').text('loading...');
$.ajax({
url: "/answer_checker.php",
global: false, type: "POST",
data: ({...clipped...}),
cache: false,
success: function(html) {
$('#response').html(html);
}
});
});
By setting the resonce content before calling the ajax function it remains showing the loading text until the ajax call updates the same content.
Thanks to everyone who took the time to answer.

You are were missing a comma after cache: false

You can also use the following:
$('#tblLoading').ajaxStart(function() { $(this).show(); });
$('#tblLoading').ajaxComplete(function() { $(this).hide(); });
