How do I set cookies for the domain?

I'd like to make this script set cookies for the domain. Right now if it sets cookies for, let's say, www.mysite.com/page_1/something.html those cookies are going to be useless for www.mysite.com/page_2/something.html

Is there a way to to make this script simply set cookies for www.mysite.com regardless of what goes after the / forward?

<script type="text/javascript">

  function setCookie(c_name,value,expiredays) {
        var exdate=new Date()
        exdate.setDate(exdate.getDate()+expiredays)
        document.cookie=c_name+ "=" +escape(value)+((expiredays==100) ? "" : ";expires="+exdate)
    }

    function getCookie(c_name) {
        if (document.cookie.length>0) {
            c_start=document.cookie.indexOf(c_name + "=")
            if (c_start!=-1) { 
                c_start=c_start + c_name.length+1 
                c_end=document.cookie.indexOf(";",c_start)
                if (c_end==-1) c_end=document.cookie.length
                    return unescape(document.cookie.substring(c_start,c_end))
            } 
        }
        return null
    }
onload=function(){
document.getElementById('myCheck').checked = getCookie('myCheck')==1? true : false;
}

</script>

<input type="checkbox" value="1" id="myCheck" onclick="set_check();">

Got it solved using this instead:

     function setCookie(name,value,days) {
    if (days) {
    var date = new Date();
    date.setTime(date.getTime()+(days*24*60*60*1000));
    var expires = "; expires="+date.toGMTString();
    }
    else var expires = "";
    document.cookie = name+"="+value+expires+"; path=/; domain=mysite.com"
    }

    function getCookie(name) {
    var nameEQ = name + "=";
    var 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;
    }

Here, try mine:

var Cookies = {
	'delete' : function(name, path, domain) {
		this.get(name) && this.set(name, '', 0, path, domain);
	}, // Cookies.delete
	
	get : function(name) {
		return name && (name = d.cookie.match(
			new RegExp('(^|;)\\s*' + name + '\\s*=\\s*([^;]*)')
		) ? unescape(name[2]) : null);
	}, // Cookies.get

	set : function(name, value, time, path, domain, secure) {
		if (
			'undefined' == typeof time ||
			time === false
		) time = 34158171600000; // 6 June 3052, 10:00AM EST
		if (Number.isInteger(time)) time = new Date(time);
		if (time instanceof Date) time = time.toGMTString();
		d.cookie = name + '=' + escape(value) +
			'; expires=' + time +
			(path ? '; path=' + path : '') +
			(domain ? '; domain=' + domain : '') +
			(secure ? '; secure' : '');
	}, // Cookies.set

	setAfter : function(name, value, time, path, domain, secure) {
		this.set(name, value, time ? new Date().getTime() + time : false, path, domain, secure);
	} // Cookies.setAfter
	
} // Cookies

With set I pass the time in MS or as an instance of Date... OR as text. If you omit the date it assumes you want to set it "forever" (well, or at least until Wobbly day)

I also pass all the other parameters you can set.

My cookie "get" routine might be of interest to you though, it's a lot cleaner/smaller/simpler. One simple regex, no looping needed.

Laugh is this REALLY is the type of thing that should be built into JavaScript but mysteriously has never even made it past the proposal stage with the ECMA. You even suggest it and the standards body goes "Well why would you need that?!?" -- even as they add endless crap to the "Math" object to account for some people being too lazy to type "1 -"

 

Oops, forgot to edit in, where it says "d." it should be "document." -- but I figured you could handle that.
