I Have a requirement where i have 3 input fields namely
1.old password
2.new password
3.confirm password.
For which i need to apply rules as follows.
1.Old and new passwords should not match.
2.No field should be empty.
3.New password and confirm password inputs should be same.
If all these validations passes then only form should be submitted.
Here is the Html file for which i need to apply js
<form role="form" method="post">
<div class="box box-primary">
<div class="box-header">
<h2 class="page-header"><i class="fa fa-lock"></i> Change Password</h2>

Reset to default 2Please replace with your ids..
function checkForm()
{
var oldP=document.getElementById("oldP").value;
var newP=document.getElementById("newP").value;
var confirmP =document.getElementById("confirmP").value;
if(oldP!=""&&newP!=""&&confirmP!="")
{
if(oldP!=newP)
{
if(newP==confirmP)
{
return true;
}
else
{
alert("Confirm password is not same as you new password.");
return false;
}
}
else
{
alert(" This Is Your Old Password,Please Provide A New Password");
return false;
}
}
else
{
alert("All Fields Are Required");
return false;
}
}
An in thml you need to add
<form onsubmit="return checkForm();" ----- >
For reset you can create a function somting like this
function resetForm()
{
var oldP=document.getElementById("oldP").value="";
var newP=document.getElementById("newP").value="";
var confirmP =document.getElementById("confirmP").value="";
}
and call when you want form reset.
firstly you should catch the click avtion on submit button and check the fields
$([name=Submit]).on('click', function(e) {
if (($('#oldPassword').val() == "")||($('#newPassword').val() == "")||($('#confirmPassword').val() == "")) {//check 2
e.preventDefault();
}
if ($('#oldPassword').val() == $('#newPassword').val()) {//check 1
e.preventDefault();
}
if ($('#newPassword').val() != $('#confirmPassword').val()) {//check 3
e.preventDefault();
}
}
P.S. i wrote code in this style because i want to show all steps. shurely you can bine 'if's in one to clear your code. as example u can bine check 1 and check 3 and put it in else block of check 2
create a function and call on onClick of button
<button type="button" name="Submit" value="Save" class="btn btn-danger" onclick="Function();"><i class="livicon" data-n="pen" data-s="16" data-c="#fff" data-hc="0" "></i> Save</button>
Your javascript Function will be Like this
<script>
function Function() {
var oldpasswprd = document.getElementById('oldPassword').value;
var newpassword = document.getElementById('newPassword').value;
var confirmpassword = document.getElementById('confirmPassword').value;
if (oldPassword == "" || newpassword == "" || confirmpassword == "") {
alert('Please fill all the details');
}
else if (oldpasswprd == newpassword) {
alert("Old password and New Password cannot be same");
}
else if (newpassword != confirmpassword) {
alert("password mismatch");
}
}
</script>
