I am trying to create a validation for a simple form in html using javascript. The problem is occurring in the if statement. The if is getting true when any one condition is getting true even if I have placed && in the statement. I html along with the js is given below:

I believe you are trying to check if all of the conditions in your statement is/are true. the best operator to use is the OR || operator. so it checks if each individual statement is true or false.
Below is your code with the fix.

<script type="text/javascript">
function validate()
{
if (document.myForm.name.value="") {
alert("should be fill");
document.myForm.name.focus();
return false;
}
return(true);

you are using assignment operator in if (document.myForm.name.value = "")
Try with this code
function validate() {
if (document.forms["myForm"]["name"].value == "") {
alert("should be fill");
document.myForm.name.focus();
return false;
}
return (true);
}
You have missed equals to == in your comparison. For comparison is should be == double equals. Change it and it should work.
if (document.myForm.name.value == "") {
...
}
It seems that you haven't added the js file in the html file. Add the js file just above ending the body tag.
<script type="text/javascript" src="location to the file"><script>
Moreover in update the js code with:
function validate(e) {
e.preventDefault();
console.log(document.myForm.name.value);
if (document.myForm.name.value == "") {
alert("should be fill");
document.myForm.name.focus();
}
}
You also need to modify the form element.
<form method="post" name="myForm" onsubmit="validate(event);" data-toggle="validator">
I am trying to send values from HTML form to javascript file but I saw that the values for email subject and message were sent as undefined in alert window or console, while the name was correctly fetched from input and transferred to js,I am quite new to javascript so this question might be very silly but I am unable to figure out the reason why undefined is sent and also I don't understand that when in what order the javascript and HTML code is executed, I Sometimes see the javascript is being executed first before the button is clicked

Javascript Jquery Experts,
I need a little help here.
This is my code, when i click on login button without putting any value in user-name & password it show message "All fields are required" but instantly as showen this message it dissapear and display unexpected message like you see when click on login button.
Now what i want ? i want when it display "All fields are required" then this message should be stable not redirect to the other unexpected message.
check also in jsfiddle: https://jsfiddle.net/m1aaaqo9/14/
1: when you click on login button checking in jsfiddle it redirect to this message: {"error":"key missing: title"}
2: I also put the same coding in my page: https://testjsvascripts.blogspot.com/p/javascript-test.html
Now when you click on login on my given page, it will redirect to display this message "Method not allowed error 405" and also add # after .html in url which i dont want.
3: same when you click on run snippet here and click on login without putting any value in user-name & password fields it will show this message "The custom error module does not recognize this error."
So my question is that: i want to display only this message " All fields are required " thats is..there should be no further redirections....So how to fix it in my code. ?
jQuery(document).ready(function($){
$("#submit").click(function(){
var name= $("#name").val();
var pass = $("#pass").val();
if(name == '' || pass == ''){
$("#Required").html("All Fields Are Required").css("color","red");
}else if(name == "admin" && pass == "123"){
$("#form").html('<h4>User Login Successfully</h4>Back').css('color','green');
}else{
$("#error").html("User Are Not Valid");
}
});
});

I am trying to validate a form and display the validation result just under the text fields on submission of form as below.
But i am not able to validate the input field on submit , but i am able to validate onBlur, i tried both ways, see belo the codes for onSubmit and onBlur respectively.
My codes for this is:
formSumbit.html
<!DOCTYPE html>
<html lang="en" ng-app="testapp">
<head>
<meta charset="utf-8"/>
<title>BoilerPlate</title>
<link rel="stylesheet" type="text/css" href="/reset.css"></link>
<link rel="stylesheet" type="text/css" href="/lib/bootstrap/css/bootstrap.css"></link>
<script src="/lib/angular/angular.js" ></script>
<script src="/lib/angular/angular-route.js" ></script>
<script src="/jquery.min.js" ></script>
<script src="/lib/bootstrap/js/bootstrap.js" ></script>
<script>
var app=angular.module('testapp', ['ngRoute']);
app.controller('signupController', ['$scope', function($scope) {
$scope.submitted = false;
$scope.signupForm = function() {
console.log("hi");
if ($scope.signup_form.$valid) {
// Submit as normal
} else {
$scope.signup_form.submitted = true;
}
}
}]);
</script>
<style type="text/css">
.error{color:red}
</style>
</head>
<body>
<div>
<form name="signup_form" ng-submit="signupForm()" novalidate >
<div class="form-group">
<label for="name">Name</label>
<input type="text" name="name" ng-model="testform.name" required class="form-control" id="name" placeholder="Name"/>
<div class="error" ng-show="signup_form.name.$dirty && signup_form.name.$error.required && signup_form.submitted">
<small class="error">
Your name is required.
</small>
</div>
</div>
<div class="form-group">
<label for="email">Email address</label>
<input type="email" name="email" ng-model="testform.email" class="form-control" id="email" placeholder="Enter email"/>
<div class="error" ng-show="signup_form.email.$dirty && signup_form.email.$invalid && signup_form.submitted">
<small class="error" ng-show="signup_form.email.$error.email">
Your email not valid
</small>
</div>
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
</div>
</body>
</html>
But i am able to do the validation in on Blur event. see the code below which is working on onBlur.
<!DOCTYPE html>
<html lang="en" ng-app="testapp">
<head>
<meta charset="utf-8"/>
<title>BoilerPlate</title>
<link rel="stylesheet" type="text/css" href="/reset.css"></link>
<link rel="stylesheet" type="text/css" href="/lib/bootstrap/css/bootstrap.css"></link>
<script src="/lib/angular/angular.js" ></script>
<script src="/lib/angular/angular-route.js" ></script>
<script src="/jquery.min.js" ></script>
<script src="/lib/bootstrap/js/bootstrap.js" ></script>
<script>
var app=angular.module('testapp', ['ngRoute']);
app.controller('signupController', ['$scope', function($scope) {
}]);
</script>
<style type="text/css">
.error{color:red}
</style>
</head>
<body>
<div>
<form name="signup_form" novalidate >
<div class="form-group">
<label for="name">Name</label>
<input type="text" name="name" ng-model="testform.name" required class="form-control" id="name" placeholder="Name"/>
<div class="error" ng-show="signup_form.name.$dirty && signup_form.name.$error.required">
<small class="error">
Your name is required.
</small>
</div>
</div>
<div class="form-group">
<label for="email">Email address</label>
<input type="email" name="email" ng-model="testform.email" class="form-control" id="email" placeholder="Enter email"/>
<div class="error" ng-show="signup_form.email.$dirty && signup_form.email.$invalid">
<small class="error" ng-show="signup_form.email.$error.email">
Your email not valid
</small>
</div>
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
</div>
</body>
</html>
Try this:
Example
<form name="form" ng-app>
<div class="control-group" ng-class="{true: 'error'}[submitted && form.email.$invalid]">
<label class="control-label" for="email">Your email address</label>
<div class="controls">
<input type="email" name="email" ng-model="email" required />
<span class="help-inline" ng-show="submitted && form.email.$error.required">Required</span>
<span class="help-inline" ng-show="submitted && form.email.$error.email">Invalid email</span>
</div>
</div>
<button type="submit" class="btn btn-primary btn-large" ng-click="submitted=true">Submit</button>
</form>
Try to set the controller on the container div
<div ng-controller="signupController">
