How to present an Alert after being redirected from an Ajax success

In my success event I want to redirect to a new page. No problem, got that. However, after being redirected to the new page I want to present a alert. I thought I could do it by using document.referrer function however this is not working for me. One problem could be that the refering page has an id at the end of the url, hence why I put the star there. But I have tried it without the star as well. What am I doing wrong ? What is the best way of achieving this ? TKS !
The sending page has this Ajax call. This works great.
$.ajax({
headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content') },
type: "POST",
url: 'save_edit/'+$id,
data: formData,
success:function(){
location.href = "http://mysite/open_quotes"
},
error:function(){
alert('there has been a system level error - please contact support')
}
});
The Receiving page has this little script at the bottom. This doesn't work:
function referedPage() {
var x = document.referrer;
if (x =="http://mysite/quote_edit/*"){
alert('Success');
}
}

You can try setting some data in local storage
localStorage['alert'] = 'true';
location.href = "http://mysite/open_quotes"
if (localStorage['alert'] == 'true'){
localStorage.removeItem('alert')
alert('Success');
}

perhaps you should do something like this:
url: 'save_edit/'+$id+'?back='+document.location,
add a back variable through an url parameter, so you can assure from where you call.

Why is my jquery ajax not working on my page and page is also refreshing

I am new in the area of jQuery/Ajax and my little test function doesn't work. And my page is also refreshingcan any one help me
<script type="text/javascript" >
$(document).ready(function() {
$("#ser_itm").change(function() {
var id=$(this).val();
var dataString = 'id='+ id;
alert(dataString);
$.ajax({
type: "POST",
url: "bar_pull.php",
data: dataString,
cache: false,
success: function(html) {
$("#tbl").html(html);
}
});
});
});

Pass the function, not the result of the function call:
$('.linkDetails').on('click', getDetailsFromServer);
Apply the same to your AJAX success callback:
success: postToPage
Also, the getDetailsFromServer() function needs to be defined before you bind it to an event. Move the function declaration before your .on('click', ...) call.

So I'm going to try and explain these points more clearly:
You cannot access C:\Users\yah\Desktop\text.txt. This is a server side path, your javascript runs on the client side. So this needs to be a path you can browse to in your browser, something like /pathinURL/text.txt. How you do this is dependant on your hosting technology, etc.
Your call backs are also wrong,
$('.linkDetails').on('click', getDetailsFromServer());
&
success: postToPage()
these will execute the function when they are hit, (well it actually binds the function result) not when the event happens. To make these work you need to remove the braces:
$('.linkDetails').on('click', getDetailsFromServer);
&
success: postToPage
this then hooks up the actual functions as function pointers and thus the actual functions will be fired when you want them to be.
so your final code will look like:
$('.linkDetails').on('click', getDetailsFromServer);
function getDetailsFromServer() {
$.ajax({
type: 'GET',
url: '/someURL/text.txt',
success: postToPage
});
}
function postToPage(data) {
$('.textDetails').text(data);
console.log(data);
}

what Arun P Johny said is right! but your code has another probloem
$('.linkDetails').on('click', getDetailsFromServer);
try above

The same origin policy implemented by browsers prevents local file system urls... if the page and the files are in same folders it might work.
See SOP for file URI for FF

Calling a javascript function from a link generated from a ajax call

I have a javascript function.
I'm making a AJAX call, and in that recieved content there is a link that I want to call the javascript function with.
MyJavascriptFunction(bla){
alert (bla);
}
Result from ajax = "Click
Do I have to do anything special with the result from AJAX to get this to work or should it just work.
I have tried it like this but with no success with clicking the link.
The AJAX call:
function doSearch() {
var form = $('form');
$.ajax({
url: "doSearch.php",
type: "GET",
data: form.serialize(),
success: function(result){
document.getElementById("result").innerHTML=result;
}
});
}
In the php I'm printing out
Click

First of all, try it. But yes you have to do something with the AJAX result. It has to be put somewhere in the DOM or the user won't be able to click on it.
Plus, make sure that the javascript function is a top level. I would suggest you use event handlers instead though.

Change your <a> tag to:
Click

You are mixing jQuery and DOM. that is not pretty
try this - assuming you do not have more than one link in the html
success: function(result){
$("#result").html(result).find("a").on("click",function() {
MyJavascriptFunction(bla);
return false;
};
}

ajax - Output not coming in a shorthand ajax code

I have made a simple code for ajax to call a page but it does not seem to be working. can anyone tell me the error?
function toggledisp(val)
{
$.ajax({
url: 'ads/xyz.php?a=' + val + '&b=2' ,
});
}
Also if we want to output the response text then how do we do so by using this method??

I would highly recommened and invite you to take a look at basic ajax tutorial using jQuery
jQuery AJAX Tutorial, Example: Simplify Ajax development with jQuery
Also if we want to output the response text then how do we do so by
using this method??
You would use success or complete handler:
$.ajax({
url:'url here',
data: {foo:'foo', bar:'bar'}, // example of data you want to send
success: function(response) {
alert(response);
}
});
For more info, see above tutorial first.

function toggledisp(val)
{
$.ajax({
url: '/ads/xyz.php' ,
data:{a:val,b:2},
success:function(output){ alert(output); }
});
}

Unexpected JavaScript Actions reported by my Users

My users keep complaining that a link does not show up for them. For me, I have tested this on several browsers and it works for me.
What should happen is that a process is started via AJAX using JQuery and once that is done I keep checking with the server via AJAX how much of the process has been done and once the process is complete I show them a link. But a lot of users tell me that it shows them the link and it quickly disappears back to showing 100.0%!
I can't see how I can fix this and I was hoping you guys could help me write something fool proof so that the link is always shown!
Here is the code concerned (its been shortened).
var startTime;
var continueTime;
var done = false;
function convertNow(validURL){
startTime = setTimeout('getStatus();', 6000);
$.ajax({
type: "GET",
url: "main.php",
data: 'url=' + validURL + '&filename=' + fileNameTxt,
success: function(msg){
done = true;
$("#loading").hide("slow");
$("#done").html("LINK SHOWN HERE");
}//function
});//ajax
}//function convertNow
function getStatus()
{
if(done==false){
$.ajax({
type: "POST",
url: "fileReader.php",
data: 'textFile=' + fileNameTxt,
success: function(respomse){
textFileResponse = respomse.split(" ");
$("#done").html("PROGRESS SHOWN HERE IN PERCENTAGES");
}
});//ajax
continueTime = setTimeout('getStatus();', 3000);
}
}
Thanks all
P.S. I have this question before and was given an idea of using a conditional in the function but that didn't work when it should have!!
UPDATE
I have some of my users what OS and browsers they are using and they usually say a Mac Os and firefox or safari. Not sure if that help with the solution.

The behaviour described by the users suggests that the success callback of your getStatus function is called after the one in convertNow. You should test done variable in this callback
function getStatus(){
if(done==false){
$.ajax({
type: "POST",
url: "fileReader.php",
data: 'textFile=' + fileNameTxt,
success: function(respomse){
// FIX : Already done, just ignore this callback
if (done) return;
textFileResponse = respomse.split(" ");
$("#done").html("PROGRESS SHOWN HERE IN PERCENTAGES");
// BONUS : call getStatus only when previous ajax call is finished
continueTime = setTimeout('getStatus();', 3000);
}
});//ajax
}
}
EDIT : This solution should prevent the bug from appearing most of the time, but there is still a chance. The only way to be sure is to remove the callback from convertNow and let the one in getStatus set the link when the processing is done (don't forget to allow only one call to getStatus at a time, see "BONUS" modification above).

If done is never set back to false then the reported behavior would be expected upon the second call to convertNow.
Since the ajax call in convertNow uses GET instead of POST, it is possible that a browser is returning a cached result whenever parameters are identical to a previous call.
