If you have an HTML Page with a form, the user fills up the form and clicks the submit button, sometimes the response from the server end is slow or the internet bandwidth of the user is slow, so the user may click the button, again and again, causing the form to be submitted more then once. This causes unwanted duplicate requests to the server thus cause a lot of trouble and unwanted bandwidth utilization. Thus one must handle this issue at the Client end so that no invalid or redundant requests are sent to the server.
There are various ways you can prevent this issue, one of the easiest and the best way is to disable the button once being clicked using jQuery attr function.
//to disable a button
$('#buttonId').attr("disabled", true);
//to enable a button
$('#buttonId').attr("disabled", false);
File : disableButton.html
<html>
<head>
<title>Disable/Enable button using jQuery</title>

<body>
<form id="form" action="welcome.php" method="get">First Name :
<input type="text" id="fname" />

<br/>Last Name :

<br/>Email :
<input type="text" id="email" />
<br/>
<br/>Username :
<input type="text" id="uname" />
<br/>
<br/>Password :
<input type="password" id="uname" />
<br/>
<br/>
<input type="button" id="button" value="Submit" onclick="validateForm()" />
</form>
<script>
function validateForm() {
$('#button').attr("disabled", true);
$("#form").submit();
}
</script>
</body>
