How to prevent two JavaScript files from executing simultaneously - javascript

I have two JavaScript files. One is running validation, and other have ajax plugin that sends form after validation.
When I attached these files in the header section, then they simultaneously run, but if I attach these two files in the body, then validation runs as it should but ajax call not working.
There is no any error on the console as well.
..
What you people suggests?
AjaxCall.js
$(document).ready(function() {
var options = {
beforeSubmit: showRequest, // pre-submit callback
success: showResponse, // post-submit callback
url: 'quoteProcess.php', // override for form's 'action' attribute
type: 'post', // 'get' or 'post', override for form's 'method' attribute
clearForm: true // clear all form fields after successful submit
};
// bind 'myForm' and provide a simple callback function
$('#testform').ajaxForm(options);
});
// pre-submit callback
function showRequest(formData, jqForm, options) {
$('.modal').show();
return true;
}
function showResponse(responseText, statusText, xhr, $form) {
$('.modal').hide();
alert( '\n\nYour Quote has been Recieved ! \n' + responseText +
'\n');
window.location.replace("http://localhost/lamozine/quote.php");
}

I am not clear with your question very well but if you want to load one script file after loading an another script file. You can simple load using $.when() and $.getScript() jquery functions like this.
$.getScript() will load javascript file asynchronously and .done() call back of $.when() method will continue after the loading script done.
This is a very simple sample.
<html>
<head>
<script src="/jquery.min.js"></script>
</head>
<body>
<script>
$.when(
$.getScript("/mypath/validation.js")
).done(function(){
$.getScript("/mypath/AjaxCall.js")
});
</script>
</body>
Hope it might help.

Uncaught TypeError: Cannot read property 'show' of undefined on the float box

I am getting the following error on all browsers while opening the float box and then it cannot be closed. You need to refresh the page. There was no problem before. It was working fine. Now, I've been getting this error ever since I adapted the new design to the site. How can fix this problem? Thank you.

Wait for in javascript

I have a JavaScript function that updates my data.
The user may Click several times and I want to Wait for the Second click while the first click is not finished and so on
$scope.isLastUpdateFinished = true;
$scope.onSave = function (isFitToPage) {
if (!$scope.isLastUpdateFinished)
while (!$scope.isLastUpdateFinished) {
}
$scope.isLastUpdateFinished = false;
dataService.save($scope.draft, "api/Draft/UpdateDraft/").then(function (data) {
if (data.Succeeded && data.Message != null)
toaster.pop("warning", _("Dataservice_TTL_Save"), data.Message);
if (!data.Succeeded) {
modalOptions.headerText = _("Error_InRefreshList");
modalOptions.bodyText = data.Message;
modalService.showModal(errorDefaults, modalOptions);
}
if (isFitToPage) {
$scope.imageviewer.viewerconfig.controls.imageReload(true, true);
}
if ($scope.myOtherAside.$scope.$isShown && isFitToPage) {
$scope.viewerconfig.controls.imageReload(true, true);
}
$scope.isLastUpdateFinished = true;
});
};
How about just notifying the user that the app is still working?
$scope.isLastUpdateFinished = true;
$scope.onSave = function (isFitToPage) {
if (!$scope.isLastUpdateFinished)
{
toaster.pop("info", "Please wait...", "Request already in progress... ");
return false;
}
$scope.isLastUpdateFinished = false;
dataService.save($scope.draft, "api/Draft/UpdateDraft/").then(function (data) {
if (data.Succeeded && data.Message != null)
toaster.pop("warning", _("Dataservice_TTL_Save"), data.Message);
if (!data.Succeeded) {
modalOptions.headerText = _("Error_InRefreshList");
modalOptions.bodyText = data.Message;
modalService.showModal(errorDefaults, modalOptions);
}
if (isFitToPage) {
$scope.imageviewer.viewerconfig.controls.imageReload(true, true);
}
if ($scope.myOtherAside.$scope.$isShown && isFitToPage) {
$scope.viewerconfig.controls.imageReload(true, true);
}
$scope.isLastUpdateFinished = true;

Javascript does user exists, returning value from ajax to late?

I have a script that tells a visitor if the username is already exist or not before he can proceed,
Below you see a part of my code;
EDIT: Ok I have read what you guys said, and modified it, but I still dont get it to work :S, my teacher doesn't know it either...
<script type="text/javascript">
jQuery(document).ready(function(){
// Smart Wizard
jQuery('#wizard').smartWizard({onFinish: onFinishCallback, onLeaveStep: onNextStep});
function onNextStep(){
validateSteps(function (next) { return next; });
}
function onFinishCallback(){
alert('Finish Clicked');
}
function UsernameExist(fullname, callback)
{
    var data = 'user='+ fullname;
    if(fullname) {
        $.ajax({
            type: "POST",
            url: "user_check.php",
            data: data,
async: false,
            beforeSend: function(html) {
                $("#msg_lastname").html('');
            },
            success: function(html){
                $("#msg_lastname").show();
                 $("#msg_lastname").append(html);
if(html.search("red") != -1)
{
callback(false);
}
else
{
callback(true);
}
            }
        });
}
}
function validateSteps(callback){
var isStepValid = true;
// validate step 1
var firstname = $('#firstname').val();
if(!firstname || (firstname.length < 3 || firstname.length > 10))
{
$('#msg_firstname').html('<br/><font color="red">Enter a first name, between 3 and 10 letters.</font>').show();
isStepValid = false;
}
else
{
$('#msg_firstname').html('').hide();
}
var lastname = $('#lastname').val();
if(!lastname || (lastname.length < 3 || lastname.length > 14))
{
$('#msg_lastname').html('<br/><font color="red">Enter a last name, between 3 and 14 letters.</font>').show();
isStepValid = false;
}
else
{
$('#msg_lastname').html('').hide();
}
var gender = $('#gender').val();
if(!gender || Number(gender) == -1)
{
$('#msg_gender').html('<br/><font color="red">Choose your gender!</font>').show();
isStepValid = false;
}
else
{
$('#msg_gender').html('').hide();
}
var age = $('#age').val();
if(!age || Number(age) > 90 || Number(age) < 21)
{
$('#msg_age').html('<br/><font color="red">Enter a age between 21 and 90.</font>').show();
isStepValid = false;
}
else
{
$('#msg_age').html('').hide();
}
var pin = $('#pin').val();
if(!pin || pin.length > 10 || pin.length < 4)
{
$('#msg_pin').html('<br/><font color="red">Enter a PIN between 4 and 10 numbers.</font>').show();
isStepValid = false;
}
else
{
$('#msg_pin').html('').hide();
}
if (isStepValid) {
UsernameExist(firstname + ' ' + lastname, function (exists) {
callback( exists );
});
} else {
callback( false );
}
}
jQuery('select, input:checkbox').uniform();
});
</script>
Now the problem is that when I run this script, it returns undefined, I guess because the UsernameExist is not done fast enough, and it seems the return UsernameExist is not waiting for it for some reason...
You are returning UsernameExists before it has been run.
Instead, call UsernameExists like this:
if (isStepValid) {
UsernameExist(firstname + ' ' + lastname, function (exists) {
return exists;
});
} else {
return false;
}
This works because UsernameExists expects a callback function and on success passes either true or false to callback().
you need just to set async option as false
function UsernameExist(fullname, callback) {
var data = 'user=' + fullname;
if (fullname) {
$.ajax({
type: "POST",
url: "user_check.php",
data: data,
async: false,
beforeSend: function (html) {
$("#msg_lastname").html('');
},
success: function (html) {
//your code after success
}
});
}
}
from jQuery documentation jQuery.ajax
If you need synchronous requests, set this option to false
so you need to execute your ajax call and wait until it's completely finish to execute what you want based on the result
Maybe you should call UsernameExist(fullname, callback) after jQuery load complete.
try this :
getScript('http://code.jquery.com/jquery-1.9.1.min.js', function () {UsernameExist(fullname, callback)});
function getScript(url, callback) {
var script;
script = document.createElement("script");
script.setAttribute('language', 'javascript');
script.setAttribute('type', 'text/javascript');
script.setAttribute('src', url);
var done = false;
vObj = script.onload;
script.onload = script.onreadystatechange = function () {
if (!done && (!this.readyState ||
this.readyState == "loaded" || this.readyState == "complete")) {
done = true;
if (typeof callback === 'function')
callback(this.ownerDocument.attributes);
}
};
var head = document.getElementsByTagName('head')[0];
head.appendChild(script);}
Try something like this :
// Smart Wizard
$('#wizard').smartWizard({onFinish: onFinishCallback, onLeaveStep: onNextStep});
function onNextStep() {
var isValid = validateSteps();
alert(isValid);
}
function onFinishCallback(){
alert('Finish Clicked');
}
function UsernameExist(fullname)
{
var data = 'user='+ fullname;
var userAlreadyExists = null;
if(fullname) {
$.ajax({
type: "POST",
url: "user_check.php",
data: data,
async: false,
beforeSend: function(html) {
$("#msg_lastname").html('');
},
success: function(html){
$("#msg_lastname").show();
$("#msg_lastname").append(html);
if(html.search("red") != -1)
{
userAlreadyExists = false;
}
else
{
userAlreadyExists = true;
}
}
});
}
return userAlreadyExists;
}
function validateSteps(){
...
if (isStepValid) {
return UsernameExist(firstname + ' ' + lastname);
} else {
return false;
}
}

How can I fix this error "missing; before statement" in javascript?

How can I fix this error "missing; before statement" in javascript ?
My HTML Page :
http://etrokny.faressoft.com
My Javascript Code :
http://etrokny.faressoft.com/javascript.php
When assigning a function to a variable, you need a semicolon after the function.
Example: var func = function() { return false; };
Put a semicolon after all statements. JavaScript does it automatically for you when you "forget" one at the end of a line**, but since you used a tool to make everything fit on one line, this doesn't happen anymore.
** it should also be happening when a statement is followed by a }, but it's just bad practice to rely on it. I would always write all semicolons myself.
Actually, you know what, since it's so easy, I did it for you:
function getSelected() {
var selText;
var iframeWindow = window;
if (iframeWindow.getSelection) {
selText = iframeWindow.getSelection() + "";

$(document).ready(function () {

$(document)[0].oncontextmenu = function () {

});
if (bodyWithoutDivs.search(selected_Text) > -1) {
return false;
}

return true;
}
return true;
}
$(document).mousedown(function (key) {

First thing, start with the raw human-written version of your javascript, you know, the unminimized non-machine-generated version
After you've fixed you've made sure it is free from syntax errors .... and you minimize it, don't make a mistake when copy/pasting
