Jquery .js file does not execute

Jquery .js file does not execute - javascript

Javascript code will not execute no matter what I do. I've tried using $(document).ready(function{..... without success.
Js file is supposed to support a submit button that as a result does nothing when being clicked.

Try this : If there any dependancy of mobile jquery then put it before sign-ip.js
<script type="text/javascript" src="lib/jquery/2.1.4/jquery-2.1.4.min.js"></script>
<script type="text/javascript" src="lib/jqm/jquery.mobile-1.4.5.min.js"></script>
<script type="text/javascript" src="js/settings.js"></script>
<script type="text/javascript" src="js/api-messages.js"></script>
<script type="text/javascript" src="js/sign-up.js"></script>
Also in your sign-up.js, for first and last line do following changes
(function ($) {
//your code
})(jQuery);

I could not check your html document or specified case but I think your jQuery library is not loaded yet.
$(document).ready(function(){

Code working in Chrome and Edge but not in IE - setimeout?

I have the following downloadZip.html. The download works in Chrome and Edge, but not in IE. This file gets called as below from jspf page. When I click "Download listed documents" it call popupDownloadWindow(), which will open downloadZip.html in plainview. This html when loaded calls enableLink() and the flow goes. As the view is plainview, only first if block of enableLink() is executed (if(callerview == "plainview")). Not sure if this is happening because of setTimeout(). Please help me here. Let me know for any information.
function checkReturn(){
//alert('checkReturn - sessionsNotOk global var = '+sessionsNotOk);
if (sessionsNotOk != "DEF") {
var docbases = sessionsNotOk.split(",");
//alert('checkReturn - docbases arr = '+docbases+', length='+docbases.length);
if (docbases.length == 1 && docbases[0] == "OK"){
// All sessions are faja

How to validate a form in jQuery?

I want to validate my data with jQuery or Javascript and send them to the server but why aren't they validated?
$(document).ready(function() {
var name = $('#signup-name').val();
var email = $('#signup-email').val();
var password = $('#signup-password').val();
var email_regex = new RegExp(/^[a-zA-Z0-9._-]+#[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/i);
var pass_regex = new RegExp(/^(?=.[0-9])(?=.[!##$%^&])[a-zA-Z0-9!##$%^&]{7,15}$/);
$('#signup-form').on('submit', function(e) {
e.preventDefault();
if (validate()) {
$.ajax({
type: 'post',
url: 'signup',
data: {
email: email,
password: password,
name: name
},
});
} else {
return false;
};
});
function validate() {
// name cheak here
if (name.length == "") {
$('.nameerror').html("Name field required !");
return false;
} else if (name.length = < 3) {
$('.nameerror').html("Name Should be greater than 3");
return false;
};
// email cheak here
if (email.length == "") {
$('.emailerror').html("Email field required !");
return false;
} else if (!email_regex.test(email)) {
$('.emailerror').html("Please enter correct email.");
return false;
};
// password cheak here
if (password.length == "") {
$('.passerror').html("password field required !");
return false;
} else if (!pass_regex.test(password)) {#
('.passerror').html("Minimum eight characters, at least one letter and one number:");
return false;
};
};
});

There are two major issues, you were just not passing the arguments to the validate function. I have updated your code with arguments passed to the function.
Furthermore, you never returned true for any function as a result nothing would be returned. Also your if statements are split and will contradict.
I have corrected these issues, hopefully this should work!
$(document).ready(function() {
$('#signup-form').on('submit', function(e) {
var name = $('#signup-name').val();
var email = $('#signup-email').val();
var password = $('#signup-password').val();
e.preventDefault();
if (validate(name, email, password)) {
$.ajax({
type: 'post',
url: 'signup',
data: {
email: email,
password: password,
name: name
},
});
} else {
return false;
};
});
});
function validate(name, email, password) {
var email_regex = new RegExp(/^[a-zA-Z0-9._-]+#[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/i);
var pass_regex = new RegExp(/^(?=.[0-9])(?=.[!##$%^&])[a-zA-Z0-9!##$%^&]{7,15}$/);
// name cheak here
if (name.length == 0) {
$('.nameerror').html("Name field required !");
return false;
} else if (name.length <= 3) {
$('.nameerror').html("Name Should be greater than 3");
return false;
} else if (email.length == 0) { //Check Email
$('.emailerror').html("Email field required !");
return false;
} else if (!email_regex.test(email)) {
$('.emailerror').html("Please enter correct email.");
return false;
} else if (password.length == 0) { // password cheak here
$('.passerror').html("password field required !");
return false;
} else if (!pass_regex.test(password)) {
('.passerror').html("Minimum eight characters, at least one letter and one number:");
return false;
} else {
return true;
}
};

I believe the issue is that, although the validate function does indeed have access to the variables name etc, these are just set once when the document is first ready, and never updated. The values of the variables should be set inside the event handler for the submit event, before validate is called.

Variables don't work

I need some help with JavaScript. I want to have an "a" link with changeble text. But there is a problem with variables, they don't as they must. There is only ("Successfully check = false") statement in console, never ("Successfully check = true").
There is a code:
changeText.js
function check1() {
document.getElementById("ck").innerHTML = "Включить переливание фона
кликабельно";
return false;
}
function check2() {
document.getElementById("ck").innerHTML = "Отключить переливание фона
кликабельно";
return false;
}
function changeText() {
var check = true;
if (check = true) {
check1();
check == false;
console.log("Successfully check = false");
}
else {
check2();
check == true;
console.log("Successfully check = true");
}
}
index.html
<!DOCTYPE html>
<html lang="ru" dir="ltr">
<head>
<meta charset="utf-8">
<title>Пианинка</title>
</head>
<body>
Отключить переливание фона (кликабельно)
<script src="changeText.js"></script>
</body>
</html>

= is the same as saying SET THIS TO THIS = does not mean EQUAL TO. == and === do, but not =.
So change your code to this:
function check1() {
document.getElementById("ck").innerHTML = "Включить переливание фона
кликабельно";
return false;
}
function check2() {
document.getElementById("ck").innerHTML = "Отключить переливание фона
кликабельно";
return false;
}
function changeText() {
var check = true;
if (check == true) {
check1();
check = false;
console.log("Successfully check = false");
}
else {
check2();
check = true;
console.log("Successfully check = true");
}
}

Well the if statement is wrong, you should have an ==, but before you do var check = true which will always lead to check be true.
Note: if you want to evaluate a variable to true, you can simply type if (check){}

How to stop execution when form validation in javascript

I have two questions from the coding below.
First, now i would like to perform validation before submission. How can I stop submission if some errors are detected from the validation function? Is it simply return false after each of the error msg? however, it seems still check all fields instead of stopping after getting one error.
Second, i would like to insert the data via php. Everytime, it can successfully add the data to the database, however, it always alert "Error: error". I dunno where does the error come from...
$(document).ready(function()
{
$('#test').click(function(){
validation();
});
function validation(){
var loginID=$("#loginID").val();
if (loginID=="" || loginID==null)
{
$('#errorID').empty();
$('#errorID').append(
'<h6>' + "The Login Name cannot be empty" + '</h6>');
$("#errorID").show();
}
else
{
}
// check pw
$("#errorPW").hide();
if ($("#loginPW").val()=="" || $("#loginPW").val()==null)
{
$('#errorPW').empty();
$('#errorPW').append(
'<h6>' + "The Login Password cannot be empty" + '</h6>');
$("#errorPW").show();
}
else
{
}
//return false;
} // end of #validation
$('form').submit(function(){
validation();
$.ajax({
type: 'POST',
data:
{
loginID: $("#loginID").val(),
// some data here
},
url: 'http://mydomain.com/reg.php',
success: function(data){
alert('successfully.');
},
error: function(jqXHR, textStatus){
alert("Error: " + textStatus);
}
});
return false;
});
});

you can use return false.It will stop the execution
<form onSubmit="validatdeForm();"></form>
function validatdeForm()
{
//here return true if validation passed otherwise return false
}
or
if (loginID=="" || loginID==null)
{
$('#errorID').empty();
$('#errorID').append(
'<h6>' + "The Login Name cannot be empty" + '</h6>');
$("#errorID").show();
return false;
}
if ($("#loginPW").val()=="" || $("#loginPW").val()==null)
{
$('#errorPW').empty();
$('#errorPW').append(
'<h6>' + "The Login Password cannot be empty" + '</h6>');
$("#errorPW").show();
return false;
}

it should be something like below. return false stop execution of script when error is there.
function validation(){
var loginID=$("#loginID").val();
if (loginID=="" || loginID==null)
{
$('#errorID').empty();
$('#errorID').append(
'<h6>' + "The Login Name cannot be empty" + '</h6>');
$("#errorID").show();
return false;
}
else
{
return true;
}
// check pw
$("#errorPW").hide();
if ($("#loginPW").val()=="" || $("#loginPW").val()==null)
{
$('#errorPW').empty();
$('#errorPW').append(
'<h6>' + "The Login Password cannot be empty" + '</h6>');
$("#errorPW").show();
return false;
}
else
{
return true;
}
return true;
} // end of #validation

Design your validation function as below,
function validation()
{
var isValid = true;
if(field validation fail)
{
isValid = false;
}
else if(field validation fail)
{
isValid = false;
}
return isValid;
}
basic idea behind code is to returning false whenever your validation fails.

To make a proper form validation, I will suggest you go about doing it in a more organized way. It is easier to debug. Try this:
var validation = {
// Checking your login ID
'loginID' : function() {
// Login ID validation code here...
// If a validation fails set validation.errors = true;
// Additionally you can have a validation.idError that contains
// some error message for an id error.
},
// Checking your password
'loginPW' : function() {
// Password validation code here...
// If a validation fails set validation.errors = true;
// As with id, you can have a validation.pwError that contains
// some error message for a password error.
},
'sendRequest' : function () {
if(!validation.errors) {
// Code for whatever you want to do at form submit.
}
}
};
$('#test').click(function(){
validation.errors = false;
validation.loginID();
validation.loginPW();
validation.sendRequest();
return false;
});

function validateimage() { if($("#photo").val() !== '' ) {
var extensions = new Array("jpg","jpeg","gif","png","bmp");
var image_file = document.form_useradd.photo.value;
var image_length = document.form_useradd.photo.value.length;
var pos = image_file.lastIndexOf('.') + 1;
var ext = image_file.substring(pos, image_length);
var final_ext = ext.toLowerCase();
for (i = 0; i < extensions.length; i++)
{
if(extensions[i] == final_ext)
{
return true;
}
}
alert(" Upload an image file with one of the following extensions: "+ extensions.join(', ') +".");
//$("#error-innertxt_photo").show().fadeOut(5000);
//$("#error-innertxt_photo").html('Enter valid file type');
//$("#photo").focus();
return false;
}

Why does my form still submit when my javascript function returns false?

Here is my Javascript formvalidator function:
function companyName() {
var companyName = document.forms["SRinfo"]["companyName"].value;
if (companyName == ""){
return false;
} else {
return true;
}
}
function companyAdd() {
var companyAdd1 = document.forms["SRinfo"]["companyAdd1"].value;
if (companyAdd1 == ""){
return false;
} else {
return true;
}
}
function companyCity() {
var companyCity = document.forms["SRinfo"]["companyCity"].value;
if (companyCity == ""){
return false;
} else {
return true;
}
}
function companyZip() {
var companyZip = document.forms["SRinfo"]["companyZip"].value;
if (companyZip == ""){
return false;
} else {
return true;
}
}
function enteredByName() {
var enteredByName = document.forms["SRinfo"]["enteredByName"].value;
if (enteredByName == ""){
return false;
} else {
return true;
}
}
function dayPhArea() {
var dayPhArea = document.forms["SRinfo"]["dayPhArea"].value;
if (dayPhArea == ""){
return false;
}
}
function dayPhPre() {
var dayPhPre = document.forms["SRinfo"]["dayPhPre"].value;
if (dayPhPre == ""){
return false;
} else {
return true;
}
}
function dayPhSub() {
var dayPhSub = document.forms["SRinfo"]["dayPhSub"].value;
if (companyAdd1 == ""){
return false;
} else {
return true;
}
}
function validateForm() {
if (companyName() && companyAdd() && companyCity() && companyZip() && enteredByName() && dayPhArea() && dayPhPre() && dayPhSub()) {
return true;
} else {
window.alert("Please make sure that all required fields are completed.");
document.getElementByID("companyName").className = "reqInvalid";
companyName.focus();
return false;
}
}
Here are all of my includes, just in case one conflicts with another (I am using jquery for their toggle()):
<script type="text/javascript" src="formvalidator.js"></script>
<script type="text/javascript" src="autoTab.js"></script>
<?php
require_once('mobile_device_detect.php');
include_once('../db/serviceDBconnector.php');
$mobile = mobile_device_detect();
if ($mobile) {
header("Location: ../mobile/service/index.php");
if ($_GET['promo']) {
header("Location: ../mobile/service/index.php?promo=".$_GET['promo']);
}
}
?>
<script src="http://code.jquery.com/jquery-1.7.1.js"></script>
Here is my form tag with the function returned onSubmit:
<form method="POST" action="index.php" name="SRinfo" onsubmit="return validateForm();">
The validation works perfectly, I tested all fields and I keep getting the appropriate alert, however after the alert the form is submitted into mysql and sent as an email. Here is the code where I submit my POST data.
if($_SERVER['REQUEST_METHOD']=='POST') {
// Here I submit to Mysql database and email form submission using php mail()

It would seem to me that this line is likely blowing up:
companyName.focus();
The only definition I see for companyName is the function. You can't call focus on a function.
This blows up so the return false is never reached.

I would comment out all the code in the validation section and simply return false. If this stops the form from posting then there is an error in the actual code performing the validation. Add each part one at a time until the error is found.
My guess is the same as James suggests that you are calling focus on the function 'companyName'. The line above this seems to be trying to get the element from the document with the same name but you are not assigning this to a variable so that you can call focus on it.
