how can i call multiple ajax request after one request complete

created two functions i want to call the get_name_from_id when my first ajax function get successful but it is not working when i add alert in get_name_from_id function after jsonstring like alert("xyz") it shows but ajax part not exectue
function get_name_from_id(){
var team_name = ("sahil","krishna");
var jsonString = JSON.stringify(team_name);
$.ajax({
dataType:"json",
type:"POST",
url:"fetchidwithname.php",
data: {team_name : jsonString},
cache: false,
success:function(a)
{
alert(a);
}
});
}
$("#matchbet").click(function(){
var matchlist = $("#match_list option:selected").val();
var jsonString = JSON.stringify(matchlist);
$.ajax({
dataType:"json",
type:"POST",
url:"selectedmatch.php",
data: {matchlist : jsonString},
cache: false,
success:function(currentmatch)
{
var current_bettable = team1 + "_vs_"+ team2 + matchdate;
var bet_team= '<select id="betting_team"><option value='+ team1 +'>'+ currentmatch.team1 + '</option><option value='+ team2 +'>'+ currentmatch.team2 + '</option></select>';
$("#teamholder").html(bet_team);
$("#current_match_table").val(current_bettable);
get_name_from_id();
}
});
});

You can use complete method of ajax
Call your function get_name_from_id() in complete method instead of success

Using document.currentScript to append data to divs

I want to append data into divs by passing their id as attributes in a script tag. In this example the first-div should get get 'test1' appended to it, and the second-div should get the 'test2' appended to it.
However, the result it that both 'test1' and 'test2' are appended to second-div. first-div is empty. I'm guessing it has to do with how document.currentScript is functioning. Is there any way to get the result I am looking for?
<div id="first-div"></div>
<div id="second-div"></div>
<script attr1="name1" attr2="name2" to-div="first-div" type="text/javascript">
var this_script = document.currentScript;
var attr1 = this_script.getAttribute('attr1');
var attr2 = this_script.getAttribute('attr2');
var append_div = this_script.getAttribute('to-div');
$.ajax({
url: "/dir?attr1=" + attr1,
type: 'GET',
success: function(data) {
$('#' + append_div).append("test1");
});
</script>
<script attr1="name3" attr2="name4" to-div="second-div" type="text/javascript">
var this_script = document.currentScript;
var attr1 = this_script.getAttribute('attr1');
var attr2 = this_script.getAttribute('attr2');
var append_div = this_script.getAttribute('to-div');
$.ajax({
url: "/dir?attr1=" + attr1,
type: 'GET',
success: function(data) {
$('#' + append_div).append("test2");
});
</script>
Also, in the solution, the scripts cannot have id attributes, which is why I am trying to use document.currentScript.
The reason for this is that the code will be hosted on my servers. The code will append information into the divs the user wants, given parameters passed through attributes on the script tag. In the end the user should be able to use:
<script attr1="var1" attr2="var2" to-div="custom-div" src="http://www.myurl.com/assets/script.js" type="text/javascript"></script>
To insert data into their custom-div based on code I run on my servers dependend on the parameters attr1 and attr2 they provide.

Your problem is that var append_div is a global variable and each time a new script tag is encountered it gets overwritten with the new value.
Since ajax is asynchronous , by the time the responses return the other script tags will have been evaluated so append_div will have the value of the last script tag.
You could fix this by creating a function that wraps the ajax
function doAjax(elementId, attr1) {
$.ajax({
url: "/dir?attr1=" + attr1,
type: 'GET',
success: function (data) {
$('#' + elementId).append("test2");
}
});
}
doAjax(append_div, attr1);
An even better solution as pointed out by #Rhumborl is to use an IIFE
(function( elementId, attr1){
$.ajax({
url: "/dir?attr1=" + attr1,
type: 'GET',
success: function (data) {
$('#' + elementId).append("test2");
}
});
}(elementId, attr1);
Or wrap all of your code in an IIFE and no arguments would need to be passed in.
(function(){
var this_script = document.currentScript;
var attr1 = this_script.getAttribute('attr1');
var attr2 = this_script.getAttribute('attr2');
var append_div = this_script.getAttribute('to-div');
$.ajax({
url: "/dir?attr1=" + attr1,
type: 'GET',
success: function(data) {
$('#' + append_div).append("test2");
}
});
}();

ajax success event doesn't work after being called

After searching here on SO and google, didn't find an answer to my problem.
The animation doesn't seem to trigger, tried a simple alert, didn't work either.
The function works as it is supposed (almost) as it does what i need to, excluding the success part.
Why isn't the success event being called?
$(function() {
$(".seguinte").click(function() {
var fnome = $('.fnome').val();
var fmorada = $('.fmorada').val();
var flocalidade = $('.flocalidade').val();
var fcodigopostal = $('.fcodigopostal').val();
var ftelemovel = $('.ftelemovel').val();
var femail = $('.femail').val();
var fnif = $('.fnif').val();
var fempresa = $('.fempresa').val();
var dataString = 'fnome='+ fnome + '&fmorada=' + fmorada + '&flocalidade=' + flocalidade + '&fcodigopostal=' + fcodigopostal + '&ftelemovel=' + ftelemovel + '&femail=' + femail + '&fnif=' + fnif + '&fempresa=' + fempresa;
$.ajax({
type: "GET",
url: "/ajaxload/editclient.php",
data: dataString,
success: function() {
$('.primeirosector').animate({ "left": "+=768px" }, "fast" );
}
});
return false;
});
});

you are trying to pass query string in data it should be json data.
Does your method edit client has all the parameters you are passing?
A simple way to test this is doing the following:
change this line to be like this
url: "/ajaxload/editclient.php" + "?" + dataString;
and remove this line
data: dataString
The correct way of doing it should be, create a javascript object and send it in the data like so:
var sendData ={
fnome: $('.fnome').val(),
fmorada: $('.fmorada').val(),
flocalidade: $('.flocalidade').val(),
fcodigopostal: $('.fcodigopostal').val(),
ftelemovel: $('.ftelemovel').val(),
femail: $('.femail').val(),
fnif: $('.fnif').val(),
fempresa: $('.fempresa').val()
}
$.ajax({
url: "/ajaxload/editclient.php",
dataType: 'json',
data: sendData,
success: function() {
$('.primeirosector').animate({ "left": "+=768px" }, "fast" );
}
});
Another thing shouldn't this be a post request?
Hope it helps

How to ensure that a function is executed completely, before navigating to another page?

I'm removing certain records using a webservice. The jquery ajax request is written in the onclick of a hyperlink. When im executing the script, line by line using firebug, it's getting removed otherwise it's not. Does any one meet any situation like this before? Please help
Code sample:
$(".target").click(function() {
func(); //This function should be executed completely before navigating to another page
});
var func = function() {
var items = $("#flag").find('td input.itemClass');
id = items[0].value;
var status = items[1].value;
var type = items[2].value;
var params = '{' +
'ID:"' + id + '" ,Type:"' + type + '" ,Status:"' + status + '"}';
$.ajax({
type: "POST",
url: "WebMethodService.asmx/DeleteItem",
data: params,
//contentType: "plain/text",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
$("#deleteNotificationMessage").val("Item has been removed"); // keep a separate label to display this message
}
//Event that'll be fired on Success
});
}

jQuery ajax functions return deferred objects, thus we return $.ajax. Then you should use deferred.done to execute the callback when the AJAX is fully finished. When the AJAX is done, navigate away using JS instead:
var func = function() {
...
return $.ajax({...}); //return our ajax deferred
}
$(".target").click(function() {
var target = this; //preserve "this" since this in the callback may be different
func().done(function(){ //our done callback executed when ajax is done
window.location.href = target.href; //assuming .target is a link
});
return false; //prevent the natural click action
});

You can use the async: false on the ajax call that is wait there to complete the call.
var func = function() {
var items = $("#flag").find('td input.itemClass');
id = items[0].value;
var status = items[1].value;
var type = items[2].value;
var params = '{' +
'ID:"' + id + '" ,Type:"' + type + '" ,Status:"' + status + '"}';
$.ajax({
type: "POST",
async: false,
url: "WebMethodService.asmx/DeleteItem",
data: params,
//contentType: "plain/text",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
$("#deleteNotificationMessage").val("Item has been removed"); // keep a separate label to display this message
}
//Event that'll be fired on Success
});
}
Alternative you can make the submit after the request.
$(".target").click(function() {
func(); //This function should be executed completely before navigating to another page
return false;
});
var func = function() {
var items = $("#flag").find('td input.itemClass');
id = items[0].value;
var status = items[1].value;
var type = items[2].value;
var params = '{' +
'ID:"' + id + '" ,Type:"' + type + '" ,Status:"' + status + '"}';
$.ajax({
type: "POST",
async: true,
url: "WebMethodService.asmx/DeleteItem",
data: params,
//contentType: "plain/text",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
$("#deleteNotificationMessage").val("Item has been removed"); // keep a separate label to display this message
$("#YourFormID").submit();
}
//Event that'll be fired on Success
});
}

Simply move the Event to the "success" handler in your ajax request:
$.ajax({
type: "POST",
url: "WebMethodService.asmx/DeleteItem",
data: params,
//contentType: "plain/text",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
$("#deleteNotificationMessage").val("Item has been removed");
//Event that'll be fired on Success
}
});
Alternatively use jQuery ajax callback methods.

How Can I Do to my textbox autocomplete, works

I'm trying to do an autocomplete to my textbox, but it doesn't work. Follow my code.
$(function () {
var credenciada = '<%= credenciadaId %>';
xml_NomeCompleto = "";
var Nomes = "";
var retorno = '';
var count = 0;
var t = '';
$.ajax({
url: "../Xml/AcessoExterno.aspx?Credenciada=" + credenciada,
type: "get",
dataType: 'xml',
async: false,
success: function (data) {
$(data).find("REGISTRO").each(function () {
t = $(this).find("NOMECOMPLETOUSUARIO").text();
Nomes += ["\"" + t + "\","];
});
}
});
$("#ctl00_contentConteudo_txtNome").autocomplete({ source: Nomes });
});
The variable 't' receives all the names of my users, normally, but the autocomplete don't work.

Wait for ajax response to complete and then initialize the autocomplete because before you initialize the plugin data is not available. Also the way you are creating Nomes(source) is wrong. Declare it as an array and use push method to populate it.
Try this
var Nomes = [];
$.ajax({
url: "../Xml/AcessoExterno.aspx?Credenciada=" + credenciada,
type: "get",
dataType: 'xml',
async: false,
success: function (data) {
$(data).find("REGISTRO").each(function () {
Nomes.push($(this).find("NOMECOMPLETOUSUARIO").text());
});
$("#ctl00_contentConteudo_txtNome").autocomplete({ source: Nomes });
}
});
