jQuery Validate Registration Form Before Submit on Button Click

Oct 4, 2013
Introduction

Here I will explain how to validate user registration form using jQuery on submit or jQuery validate form before submit on button click.
 
Description:


To implement this we need to write the code like as shown below


<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1">
<title>jQuery Registration Form Validation</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.js"></script>
<script language="javascript" type="text/javascript">
$(function() {
$('#btnvalidate').click(function() {
var summary = "";
summary += isvaliduser();
summary += isvalidFirstname();
summary += isvalidLocation();
if (summary != "") {
alert(summary);
return false;
}
else {
return true;
}
})
})
function isvaliduser() {
var temp = $("#txtuser").val();
if (temp == "") {
return ("Please Enter UserName" + "\n");
}
else {
return "";
}
}
function isvalidFirstname() {
var temp = $("#txtfname").val();
if (temp == "") {
return ("Please Enter firstname" + "\n");
}
else {
return "";
}
}
function isvalidLocation() {
var temp = $("#txtlocation").val();
if (temp == "") {
return ("Please Enter Location" + "\n");
}
else {
return "";
}
}
</script>
</head>
<body>
<form id="form1">
<table align="center">
<tr>
<td>UserName</td>
<td>
<input type="text" id="txtuser" />
</td>
</tr>
<tr>
<td>First Name</td>
<td>
<input type="text" id="txtfname" />
</td>
</tr>
<tr>
<td>Location</td>
<td>
<input type="text" id="txtlocation" />
</td>
</tr>
<tr>
<td></td>
<td>
<input type="button" value="Validate" id="btnvalidate" />
</td>
</tr>
</table>
</form>
</body>
</html>
Live Demo

To check for live demo try to click on below button
UserName
First Name
Location

Note: if you want to use for asp.net controls replace $("#txtlocation").val(); you’re your asp.net control id like this $("#<%=txtlocation.ClientID %>").val()
