Javascript Cookie problems IE
been bagging my head over some Javascript, please help, I cant see why it simply wont find my cookie in IE 7 or 8
I am setting the cookie true through another event, but I just want to see IE pick up the cookie which I initially set. Works in firefox too, thanks in advance.
var t=setTimeout("doAlert()",8000);
var doAlertVar = true;
document.cookie = "closed=0;expires=0;path=";
function readCookie(name) {
var nameEQ = name + "=";开发者_如何学运维
var ca = document.cookie;
alert(ca);
ca = ca.replace(/^\s*|\s*$/g,'');
ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
function doAlert(){
if(readCookie('closed')==1){
doAlertVar = false;
}
if(readCookie('closed')==0){
alert("unlicensed demo version\nbuy online at");
}
t=setTimeout("doAlert()",5000);
}
Where to begin..
setTimeout("doAlert()",8000);
// do not use strings as an argument to setTimeout, that runs eval under the hood.
// use
setTimeout(doAlert,8000);
// instead
document.cookie = "closed=0;expires=0;path=";
// this is wrong, expires should follow the format Fri, 14 May 2010 17:22:33 GMT (new Date().toUTCString())
// path should be path=/
You can also do this with a regex:
function readCookie(name, defaultValue) {
var value = defaultValue;
document.cookie.replace(new RegExp("\\b" + name + "=([^;]*)"), function(_, v) {
value = v;
});
return value;
}
