I have three functions that called as shown below (Functions not included):
Code:
$("#btnSubmit").click(function() {
var data = JSON.stringify(getAllSourcepData());
console.log(data);
$.ajax({
url: 'closures.aspx/SaveSourceData',
type: 'POST',
contentType: 'application/json; charset=utf-8',
data: JSON.stringify({
'empdata': data
}),
success: function() {
alert("Data Added Successfully");
},
error: function() {
alert("Error while inserting data");
}
});
});
$("#btnSubmit").click(function() {
var data = JSON.stringify(getAllSpouseData());
console.log(data);
$.ajax({
url: 'closures.aspx/SaveSpousData',
type: 'POST',
contentType: 'application/json; charset=utf-8',
data: JSON.stringify({
'empdata': data
}),
success: function() {
alert("Data Added Successfully");
},
error: function() {
alert("Error while inserting data");
}
});
});
$("#btnSubmit").click(function() {
var data = JSON.stringify(getAllDividentData());
console.log(data);
$.ajax({
url: 'closures.aspx/SaveDividentData',
type: 'POST',
contentType: 'application/json; charset=utf-8',
data: JSON.stringify({
'empdata': data
}),
success: function() {
alert("Data Added Successfully");
},
error: function() {
alert("Error while inserting data");
}
});
});
When data is submitted successfully, three alert boxes popup, each with same message: "Data Added Successfully".
This forces user to have to close three popup boxes.
Is there a way to disable the success alert boxes leaving just one? Or even all three be disabled allowing me to come up with a custom Success message?
You could also simplified your code by using Promise.all:
$("#btnSubmit").click(function() {
var allSourcepData = JSON.stringify(getAllSourcepData());
var allSpouseData = JSON.stringify(getAllSpouseData());
var allDividentData = JSON.stringify(getAllDividentData());
Promise.all([
getData('closures.aspx/SaveSourceData', allSourcepData),
getData('closures.aspx/SaveSpousData', allSpouseData),
getData('closures.aspx/SaveDividentData', allDividentData)
])
.then( alert )
.catch( alert )
});
function getData(url, data)
{
return new Promise((resolve, reject){
$.ajax({
url: url,
type: 'POST',
contentType: 'application/json; charset=utf-8',
data: JSON.stringify({
'empdata': data
}),
success: () => { resolve("Data Added Successfully") },
error: () => { reject("Error while inserting data"); }
});
})
}
You need to wait until all ajax requests are complete, like in this answer
So in your case you need to create functions for all $.ajax calls like this:
function ajax1() {
var data = JSON.stringify(getAllSourcepData());
$.ajax({
url: 'closures.aspx/SaveSourceData',
type: 'POST',
contentType: 'application/json; charset=utf-8',
data: JSON.stringify({
'empdata': data
}),
success: function() {
alert("Data Added Successfully");
},
error: function() {
alert("Error while inserting data");
}
});
}
// add ajax2() and ajax3() ...
And then use only one click handler like this:
$("#btnSubmit").click(function() {
$.when(ajax1(), ajax2(), ajax3()).then(function(a1, a2, a3){
// success, display message
}, function(){
// exception
});
});
You can reorder a little your code to use the deferred method to jQuery 1.5+ otherwise you can implement as this answer:
jQuery callback for multiple ajax calls
Why you want to call 3 times for button click?
Why not put them all together?
Any how you can use variable as isAlertToBeShown= false and after pushing data make it has true. finally check the variable is true or false.

I have a text area with id "text" and I am toggling the text area to appear on the screen with a click event on some div and I have 30 such divs.
Initially , I'm assigning the textarea.value with result of ajax call to my fetch api which fetches the data from the mongo on the server side based on an unique id.
Sometimes , when I'm making the ajax call to my update api in my backend , the textarea.value I'm sending as data to this ajax call is not the same as the updated text of the text area.
//client side
// called when any of the divs is clicked
$(".radius").on("click", function(event) {
//extracting the id from the class and using this id as the id of my data for my mongo
var st=event.target.classList[1].substring(0,7);
var num=parseInt(event.target.classList[1].substring(7));
var toadd="close-button"+num;
//console.log(num+"modal")
closeButton.classList.add(toadd);
$.ajax({type: "POST",
url: "/fetch",
async: true,
data: JSON.stringify({
id: num,
}),
dataType: 'json',
contentType: 'application/json; charset=utf-8',
success:function(result) {
input.value=result.text;
},
error:function(result) {
console.log("error")
}
});
modal.classList.toggle("show-modal");
});
// called when textarea is closed
function toggleModal1(event) {
var s1=closeButton.classList[closeButton.classList.length-1];
var st=s1.substring(12);
closeButton.classList.remove(s1);
var num=parseInt(st);
// event.preventDefault();
console.log(input.value)
$.ajax({type: "POST",
url: "/update",
data: JSON.stringify({
id:num,
text:input.value,
//input is my textarea
}),
dataType: 'json',
contentType: 'application/json; charset=utf-8',
success:function(result) {
},
error:function(result) {
console.log("error")
}
});
modal.classList.toggle("show-modal");
}
//server side
app.post("/fetch",function(req,res)
{
//console.log(req.body);
// var id1=req.body.id;
const findInDB= Fruit.findOne({id:req.body.id},function (err, docs) {
console.log(docs);
res.send({text:docs.text});
});
});
app.post("/update",function(req,res)
{
Fruit.updateOne({id:req.body.id},
{text:req.body.text}, function (err, docs) {
if (err){
console.log(err)
}
else{
console.log("Updated Docs : ", docs);
}
});
I have created a save(id) function that will submit ajax post request. When calling a save(id). How to get value/data from save(id) before going to next step. How to solve this?
For example:
function save(id) {
$.ajax({
type: "POST",
url: "/post/",
dataType: "json",
contentType: 'application/json',
data: JSON.stringify({
id: id,
}),
success: function (data) {
return data;
},
error: function (error) {
return data;
}
});
}
Usage:
$('.btn-create').click(function () {
var id = 123;
data = saveArea(id); //get data from ajax request or error data?
if (data) {
window.location = "/post/" + data.something
}
}
You have two options, either run the AJAX call synchronously (not recommended). Or asynchronously using callbacks
Synchronous
As #Drew_Kennedy mentions, this will freeze the page until it's finished, degrading the user experience.
function save(id) {
return $.ajax({
type: "POST",
url: "/post/",
dataType: "json",
contentType: 'application/json',
async: false,
data: JSON.stringify({
id: id,
})
}).responseText;
}
$('.btn-create').click(function () {
var id = 123;
// now this will work
data = save(id);
if (data) {
window.location = "/post/" + data.something
}
}
Asynchronous (recommended)
This will run in the background, and allow for normal user interaction on the page.
function save(id, cb, err) {
$.ajax({
type: "POST",
url: "/post/",
dataType: "json",
contentType: 'application/json',
data: JSON.stringify({
id: id,
}),
success: function (data) {
cb(data);
},
error: err // you can do the same for success/cb: "success: cb"
});
}
$('.btn-create').click(function () {
var id = 123;
save(id,
// what to do on success
function(data) {
// data is available here in the callback
if (data) {
window.location = "/post/" + data.something
}
},
// what to do on failure
function(data) {
alert(data);
}
});
}
Just make things a bit simpler.
For starters just add window.location = "/post/" + data.something to the success callback.
Like this:
function save(id) {
return $.ajax({
type: "POST",
url: "/post/",
dataType: "json",
contentType: 'application/json',
data: JSON.stringify({
id: id,
}),
success:function(data){
window.location = "/post/" + data.something
}
}).responseText;
}
Or by adding all your Ajax code within the click event.
$('.btn-create').click(function () {
var id = "123";
$.ajax({
type: "POST",
url: "/post/",
dataType: "json",
contentType: 'application/json',
data: JSON.stringify({
id: id,
}),
success: function (data) {
window.location = "/post/" + data.something
},
error: function (error) {
console.log(error)
}
});
}
I am trying to make a comment form which adds a comment in array of blog schema
but when I am using ajax it is giving undefined below the places where I have console log and when I am using simple post request it is working fine.
I am using mongoose, nodejs , express, jquery ajax
my script is as follows
var frm = $('#commentForm');
frm.submit(function (e) {
e.preventDefault();
console.log('clicked');
$.ajax({
type: 'POST',
url: "/blog/addComment",
contentType: "application/json; charset=utf-8",
dataType: 'json'
})
.done(function(data) {
addNewComment(data);
})
.fail(function() {
console.log("Ajax failed to fetch data");
});
});
function addNewComment(data){
console.log(data);
}
my routes is as follows
//add comments
router.post('/addComment',function(req,res,next){
console.log(req.body.comment+" "+ req.body.userId+" "+req.body.postId);
var newComment = {
'text': req.body.comment,
'author': req.body.userId
}
Post.addComment(req.body.postId, newComment, function(err,comment){
if(err) throw err;
console.log(comment);
res.send(comment);
});
});
and my mongoose schema is
//add comments
module.exports.addComment = function( postId, newComment, callback){
var query = { '_id': postId};
console.log('postid: '+postId+" newcomment: "+newComment.text+ " "+newComment.author);
Post.findOneAndUpdate( query, { $push:{'comments': newComment} }, {new:true} , callback);
}
That's because data is not defined in ajax call ,
use following provide the frm is the actallu form or use
use data : form name.serialize()
var frm = $('#commentForm');
frm.submit(function (e) {
e.preventDefault();
console.log('clicked');
$.ajax({
data : $(this).serialize(),
type: 'POST',
url: "/blog/addComment",
contentType: "application/json; charset=utf-8",
dataType: 'json'
})
.done(function(data) {
addNewComment(data);
})
.fail(function() {
console.log("Ajax failed to fetch data");
});
});
I have following code in my send.js:
function send_upload_file(){
var FD = new FormData();
FD.append( $this.name, $this.value);
$.ajax({
url: 'upload',
type: 'POST',
processData: false,
contentType: false,
cache: false,
data: FD,
success: function (data) {
console.log('ok');
},
error: function () {
alert("ERROR in upload");
}
});
}
Can I put two links inside url:? (e.g url: 'upload, send')
No. If you wanna send two AJAX requests, you need to do it twice. But the shorthand for this would be:
var success = function () {
console.log("OK");
};
$.post("upload", FD, success);
$.post("send", FD, success);
The above works asynchronously. If you want to do it synchronously, you need to do:
$.post("upload", FD, function () {
console.log("OK");
$.post("send", FD, function () {
console.log("Sent");
});
});
No you can't but try ajax after the first one success
$.ajax({
url: 'upload',
success: function (data) {
$.ajax({
url: 'send',
});
},
error: function () {
alert("ERROR in upload");
}
});
var ajaxRequest = new enyo.Ajax({
cacheBust: false,
contentType: 'application/json;charset=utf-8',
method: 'POST',
timeout: 8000,
async: false,
handleAs: 'json',
data: JSON.stringify({
// Data to connect to the external service.
url: url
method: 'GET',
contenttype: 'application/json;charset=utf-8',
content: 'username=l&pwd=p' + searchParams
}),
success: function (inSender, inResponse) {
},
fail: function (inSender, inResponse) {
}
ajaxRequest.go(ajaxRequest.data).response('success').error('fail');
};
lets say ,call to the webservice taking 5 to 6 seconds time or if there is slow internet connection ,How to redirect to fail block
what about manually call to fail-callback-func, something like:
var getDataFail = true;
function getData() {
setTimeOut(fileCallbackFunc, 6000);
$.ajax({
url: yourURL,
success: doneCallbck,
error: doneCallbck,
//other ajax params
});
}
function fileCallbck() {
if (getDataFail) {
//your fail logic...
console.error('get data fail');
}
}
function doneCallbck() {
getDataFail = false;
console.error('get data done');
}
