Question

我是JavaScript的新手，我坚持使用我创建的代码来显示cookie用户名和命中数。问题是使用setCookies（）函数时cookie值不是更新，但是一次又一次地输出相同的值。请帮我解决。

＆＃13;

function setCookie(cname, cvalue, exdays, visits) {
    var d = new Date();
    d.setTime(d.getTime() + (exdays*24*60*60*1000));
    var expires = "expires="+d.toUTCString();
	var visit = visits.toString()
    document.cookie = cname + "=" + cvalue + "; " + expires + "; visits=" + visit;
}

function getCookie(cname) {
    var name = cname + "=";
    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);
        if (c.indexOf(name) == 0) return c.substring(name.length, c.length);
    }
    return "";
}

function checkCookie() {
    var user = getCookie("username");
	var visitCount = getCookie("visits");
	var visitCountConverted = Number(visitCount);
	if (visitCountConverted == "") {
	visitCountConverted = 1;
	}
	else if (visitCountConverted >= 1){
	visitCountConverted += 1;
	}
    if (user != "") {
        alert("Cookie: " + user + "\n" + "Visits: " + visitCountConverted);
		setCookie("username", user, 365, visitCountConverted);
    } else {
        user = "TheName"; alert("Cookie: " + user + "\n" + "Visits: " + visitCountConverted); setCookie("username", user, 365, visitCountConverted);
    }
}

非常感谢。

function setCookie(cname, cvalue, exdays) {
    var d = new Date();
    d.setTime(d.getTime() + (exdays*24*60*60*1000));
    var expires = "expires="+d.toUTCString();
    document.cookie = cname + "=" + cvalue + "; " + expires ;
}

function getCookie(cname) {
    var name = cname + "=";
    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);
        if (c.indexOf(name) == 0) return c.substring(name.length, c.length);
    }
    return "";
}

function checkCookie() {
    var user = getCookie("username");
    var visitCount = getCookie("visits");
    var visitCountConverted = Number(visitCount);
    if (visitCountConverted == "") {
        visitCountConverted = 1;

    }
    else if (visitCountConverted >= 1){
        visitCountConverted += 1;
    }
    if (user == "") {
        user = "TheName";
        setCookie("username", user, 365);

    }
    alert("Cookie: " + user + "\n" + "Visits: " + visitCountConverted);

    setCookie("visits", visitCountConverted, 365);
}
checkCookie();//make sure to call this method so that cookies get set

你没有设置访问计数器cookie我已经重构了你的代码所以请你去试试

我的cookie值没有更新/更改
