javascript Set as homepage Add to favorites JS code

We introduce a code for adding to favorites that is compatible with all browsers. The general principle is as follows: We judge the browser based on obtaining user navigator.userAgent.toLowerCase() information, and whether the browser supports adding to favorites js command, if it can be automatically collected, otherwise it will prompt ctrl D to collect it manually. 1 function addFavorite2() { 2 var url = window.location; 3 var title = document.title; 4 var ua = navigator.userAgent.toLowerCase(); 5 if (ua.indexOf("360se" ) > -1) { 6           alert("Due to 360 browser function limitations, please press Ctrl D to collect manually!"); 7     } 8   else if (ua.indexOf("msie 8") > -1) { 9 window.external.AddToFavoritesBar(url, title); //IE810 }11 else if (document.all) {12 try{13 window.external.addFavorite(url, title);14 }catch(e){15 alert(' Your browser does not support it, please press Ctrl D to bookmark it manually!');16 }17 }18 else if (window.sidebar) {19 window.sidebar.addPanel(title, url, "");20 }21 else { 22 alert('Your browser does not support it, please press Ctrl D to bookmark it manually!');23 }24 }

Copy the code of this page and save it as a js file, and then add it where you want to bookmark it Up
