Introduction
Here I will explain how to set default home page in browser using JavaScript in asp.net.
Description
In many major websites we will see link like “Set as a home page” if we click on that home page link that will automatically change our browser default home page url to their particular page url. In IE browser we can easily set home page just by simple code but Mozilla we don’t have a chance to set home directly because of security concerns. If we want to set the home page in Mozilla first we need to set signed.applets.codebase_principal_support to true then run the below code to set home page initially that is in false mode.
To enable this property in Mozilla follow below steps
1. 1) First open Mozilla browser and type about:config in address bar and click enter
2. 2) Now it will show some warning message click ok and now search for signed.applets.codebase_principal_support right click on it and select Toggle now Value will change to true
3) Once that property set then run the below code and click on set as home page button it will automatically will set your url as the home page.
Write the below code in your page to set home page in your IE and Mozilla browsers
<html xmlns="http://www.w3.org/1999/xhtml"> <head id="Head1" runat="server"> <title>Add BookMark it Link to your website using JavaScript</title> <script language="javascript" type="text/javascript"> function setHomepage() { //Condition to set home page in IE if (document.all) { document.body.style.behavior = 'url(#default#homepage)'; document.body.setHomePage('http://www.aspdotnet-suresh.com'); } //Condition to set home page in Mozilla else if (window.sidebar) { if (window.netscape) { try { netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect"); } catch (e) { alert("this action was aviod by your browser，if you want to enable，please enter about:config in your address line,and change the value of signed.applets.codebase_principal_support to true"); } } var prefs = Components.classes['@mozilla.org/preferences-service;1'].getService(Components.interfaces.nsIPrefBranch); prefs.setCharPref('browser.startup.homepage', 'http://www.aspdotnet-suresh.com'); } } </script> </head> <body> <form id="form1" runat="server"> <input type="button" value="set home page" onclick="setHomepage();" /> </form> </body> </html> |
After add above code run your application and check your output it will work for you
