  This article mainly introduces sample code that determines whether a client browser supports cookies. Need friends can come to the reference, I hope to help you.

1.   Code as follows: function check () {  if (window.navigator.cookieEnabled)      return true;   else{      alert ("Browser configuration error, cookies not available!") ");      return false;  }     2.   Code as follows: Setcookie (' cookie_test ', ' 1 ');   var cookie_test = GetCookie (' cookie_test ');   if (' 1 '!= cookie_test)   {   alert (' unsupported ');  }else   {   alert (' support ');   }     function Setcookie (name,value)//two parameters, one is the name of the cookie, one is the value    {     var days = 30; /This cookie will be saved for 30 days       var exp = new Date (); New Date ("December 31, 9998");       exp.settime (exp.gettime () + days*24*60*60*1000);      document.cookie = name + "=" + Escape (value) + "expires=" + exp.togmtstring ();  }   function GetCookie (name)/Fetch cookies function       {     var arr = Document.cookie. Match (New RegExp ("(^|)" +name+ "= ([^;] *)(;|$)"));      IF (arr!= null) return unescape (arr[2)); return null;    }   function Delcookie (name)//delete cookie    {     var exp = new Date ();      exp.settime (Exp.gettime ()-1);      var Cval=getcookie (name);      if (cval!=null) document.cookie= name + "=" +cval+ "; expires=" +exp.togmtstring ();  }     3.   Code as follows: Var cookieenabled= (navigator.cookieenabled)? True:false  //Judge whether the cookie is open     //If the browser is not ie4+ or ns6+    if (typeof navigator.cookieenabled = = "undefined" &&!cookieenabled) {   document.cookie= "TestCookie"   cookieenabled= ( document.cookie== "TestCookie")? True:false   document.cookie= ""//erase Dummy Value   }
