Allow only numeric (0-9) Or Numeric With Decimal in HTML inputbox using jQuery


How to allow only numeric (0-9) Or Numeric With Decimal in HTML inputbox using jQuery?


I am creating a web page where I have an input text field in which I want to allow only numeric characters like (0,1,2,3,4,5...9) 0-9.


<script>
$(document).ready(function () {
//Allow Number Only in Textbox
$(".allownumber").on("keypress keyup blur", function (event) {
$(this).val($(this).val().replace(/[^\d].+/, ""));
if ((event.which < 48 || event.which > 57)) {
event.preventDefault();
}
});
//Allow Number Only in Textbox

//Allow Number With decimal Only in Textbox
$(".allownumberwithdecimal").on("keypress keyup blur", function (event) {
//this.value = this.value.replace(/[^0-9\.]/g,'');
$(this).val($(this).val().replace(/[^0-9\.]/g, ''));
if ((event.which != 46 || $(this).val().indexOf('.') != -1) && (event.which < 48 || event.which > 57)) {
event.preventDefault();
}
});
//Allow Number With decimal Only in Textbox
});
</script>



<span>Float</span>
<input type="text" name="numeric" class='allownumberwithdecimal'>
<div>Numeric values only allowed (With Decimal Point) </div>
<br/> <br/> <br/>
<span>Int</span>
<input type="text" name="numeric" class='allownumber'>
<div>Numeric values only allowed (Without Decimal Point) </div>

Disable Browser Back Button after LogOut in ASP.Net using JavaScript


How to disable Back button in Browser after Logout using JavaScript.

Browser Back button cannot be disabled and hence in order to prevent User navigating to previous page, the User is redirected back to the Current page forcefully using JavaScript.

Disable Browser Back Button Script
The following JavaScript code snippet must be placed in the HEAD section of the Page where the User must be prevented from going back.
<script type = "text/javascript" >
   function preventBack(){window.history.forward();}
    setTimeout("preventBack()", 0);
    window.onunload=function(){null};
</script>

Home Page

The HTML Markup of Home page consists of an HTML Anchor link to the Logout page.
The Disable Browser Back Button Script is placed in the HEAD section so that User cannot access the Home page using Browser Back button from Logout page.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="Test" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Home</title>
<script type="text/javascript">
function preventBack() { window.history.forward(); }
setTimeout("preventBack()", 0);
window.onunload = function () { null };
</script>
</head>
<body>
<h3>Home</h3>
<hr />
<a href="Logout.aspx">Logout</a>
</body>
</html>


Logout Page
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="logout.aspx.cs" Inherits="Test" %>
