How to stop execution in jquery for 1 sec

I want to submit form using ajax and hide button and show message.
I used "async:false" into ajax that's why button is not hiding. If I use "async:true" then it working.
$(document).ready(function (e) {
$("#submit_form").on('submit',(function(e) {
$('#btn1').css('display','none');
$("#show1").css('display','block');
e.preventDefault(e);
var chkArray = [];
var chkArray1 = [];
$('#loading').show();
var inps = document.getElementsByName('chk_url[]');
//sleep(1000);
for (var i = 0; i <inps.length; i++) {
var inp=inps[i];
if($(inp).is(':checked')){
var site_url=$('#site_urls').val(inp.value);
$.ajax({
url: $('#site_urls').val(),
type: "POST",
data: new FormData(this),
contentType: false,
cache: false,
processData:false,
async:false,
success: function(data)
{
if(data=='done'){
chkArray.push($('#site_urls').val());
}else{
chkArray1.push($('#site_urls').val());
}
}
});
}
}
}));
});
Is there another way to execute hide code before ajax execution??
I have used "delay(1000)" and "sleep(1000)".
I cannot use "setTimeout" function.

Don't use the ajax call in for loop, use outside the loop,
I have change your code, let i know it is helpful..
$(document).ready(function (e) {
$("#submit_form").on('submit',(function(e) {
$('#btn1').css('display','none');
$("#show1").css('display','block');
e.preventDefault(e);
var chkArray = [];
var chkArray1 = [];
$('#loading').show();
var inps = document.getElementsByName('chk_url[]');
//sleep(1000);
var fd = new FormData();
for (var i = 0; i <inps.length; i++) {
var inp=inps[i];
if($(inp).is(':checked')){
fd.append( 'site_urls', inp.value );
}
}
/*send call to server start here*/
$.ajax({
url: $('#site_urls').val(),
type: "POST",
data: fd,
contentType: false,
cache: false,
processData:false,
async:false,
success: function(data)
{
if(data=='done'){
chkArray.push($('#site_urls').val());
}else{
chkArray1.push($('#site_urls').val());
}
}
});
/*send call to server ens here*/
}));
});

jQuery clearinterval / stopinterval doesn't work

I have an autorefresh function that gets called if a checkbox is checked and a button clicked. I want to stop the autorefresh when the checkbox is unclicked:
var refreshId = null;
$("#disINFRAlive").click(function(infralivefun) {
event.preventDefault(infralivefun);
var category_id = {};
category_id['datumanf'] = $("#datumanf").datepicker().val();
category_id['datumend'] = $("#datumend").datepicker().val();
$.ajax({ //create an ajax request to display.php
type: "POST",
url: "infratestomc.php?id=" + Math.random(),
dataType: "html",
data: category_id,
success: function(response) {
$("#resulttabelle").show().html(response);
}
});
if ($('#autorefcheck').is(':checked')) {
var refreshId = setInterval(function() {
var category_id = {};
category_id['datumanf'] = $("#datumanf").datepicker().val();
category_id['datumend'] = $("#datumend").datepicker().val();
$.ajax({ //create an ajax request to display.php
type: "POST",
url: "infratestomc.php?id=" + Math.random(),
dataType: "html",
data: category_id,
success: function(response) {
$("#resulttabelle").show().html(response);
}
});
}, 5000);
}
});
The autorefresh works if the checkbox #autorefcheck is checked and the button #disINFRAlive is clicked. However, I can't make it stop by unchecking the checkbox:
function stopinterval(){
clearInterval(refreshId);
return false;
}
$('#autorefcheck').click(function() {
stopinterval();
});
I tried to use clearInterval in various ways and none worked so far.

Remove the var keyword from the initialization of refreshId.
if ($('#autorefcheck').is(':checked')) {
refreshId = setInterval(function() {
The way you have it, you are redeclaring the variable in a different scope. That way, you cannot access it from stopInterval().

loading div not working on jquery

my html:
<span id="loading"><img src="ajax-loader.gif" /> Please Wait</span>
#loading{display:none;}
my js:
var Progressajax = false;
$(function() {
$(".commentmoreview").click(function(){
if(Progressajax) return;
Progressajax = true;
var element = $(this);
var id = element.attr("id");
$('#loading').show();
var value = $('.pagecont'+id).val();
var info = 'id='+id+'&pagecont='+value;
$.ajax({
type: "POST",
url: "php-comments/php/loadmorecomments.php",
data: info,
success: function(data){
$('#loading').hide();
Progressajax = false;
value = parseInt(value)+parseInt(5);
$('.pagecont'+id).val(value);
$(data).hide().prependTo('#loadmorecomments'+id).fadeIn(1000);
//$('#loadmorecomments'+id).prepend(data);
}
});
});
});
what is wrong that loading span is not working?
thank you friends!

The best way to show loader image while making ajax calls is using Ajax Global Events
$(document).bind("ajaxSend", function(){
$("#loading").show();
}).bind("ajaxComplete", function(){
$("#loading").hide();
});

can you change
$('#loading').show();
to
$('#loading').attr("display","block");
and try to use it like this
$.ajax({
type: "POST",
url: "php-comments/php/loadmorecomments.php",
data: info,
beforeSend: function(){
$('#loading').attr("display","block");
},
success: function(data){
$('#loading').attr("display","none");
Progressajax = false;
value = parseInt(value)+parseInt(5);
$('.pagecont'+id).val(value);
$(data).hide().prependTo('#loadmorecomments'+id).fadeIn(1000);
//$('#loadmorecomments'+id).prepend(data);
}
});

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 });
}
});

Javascript when to show results

This is my Javascript below I want to show records on load and also show new records when added to the database
showrecords(); displays the records in the database where abouts can I put this in my code where it will work correctly.
$(document).ready(function()
{
//showrecords()
function showrecords()
{
$.ajax({
type: "POST",
url: "demo_show.php",
cache: false,
success: function(html){
$("#display").after(html);
document.getElementById('content').value='';
$("#flash").hide();
}
});
}
$(".comment_button").click(function() {
var element = $(this);
var test = $("#content").val();
var dataString = 'content='+ test;
if(test=='')
{
alert("Please Enter Some Text");
}
else
{
$("#flash").show();
$("#flash").fadeIn(400)
.html('<img src="http://tiggin.com/ajax-loader.gif" align="absmiddle"> <span class="loading">Loading Comment...</span>');
$.ajax({
type: "POST",
url: "demo_insert.php",
data: dataString,
cache: false,
success: function(html){
// $("#display").after(html);
document.getElementById('content').value='';
$("#flash").hide();
//Function for showing records
//showrecords();
}
});
}
return false;
});
});

Though polluting the global namespace is not recommended. Here is what I would recommend for your code. Move the showRecords() out of Document ready function and refactor the update ajax code to another function 'updateRecords()'. Have only the event bindings inside the document ready function.
You could return the entire comments as response to POST 'demo_insert.php' service and call 'showRecords()' in the update service success callback.

i've pasted below (untested) code that i think should get the job done. in order to call functions you've got to define them in an accessible area, whether in the "global" (can be called from anywhere) namespace as i've done below, or as part of an another object.
you also need to make sure your functions are defined before you try to call them, as everything works in a top down manner.
function showrecords() {
$.ajax({
type: "POST",
url: "demo_show.php",
cache: false,
success: function (html) {
$("#display").after(html);
$('content').val('');
$("#flash").hide();
}
});
}
function addComment() {
var test = $("#content").val();
var dataString = 'content=' + test;
if (test == '') {
alert("Please Enter Some Text");
}
else {
$("#flash").show();
$("#flash").fadeIn(400)
.html('<img src="http://tiggin.com/ajax-loader.gif" align="absmiddle"> <span class="loading">Loading Comment...</span>');
$.ajax({
type: "POST",
url: "demo_insert.php",
data: dataString,
cache: false,
success: function (html) {
//$("#display").after(html);
$('content').val('');
$("#flash").hide();
//Function for showing records
showrecords();
}
});
}
}
$(document).ready(function () {
showrecords()
$(".comment_button").click(function () {
addComment();
return false;
});
});
