Javascript 设置cookies不需要'；I don’我没有按预期工作

我正在努力实现的目标：

按下href时，我调用

saveItem（）

函数。其名称如下：

---

就像你自己做的那样
是cookie中介于值、过期日期等之间的字段分隔符。您不能使用它来分隔值。
好的，所以问题出在分隔符和我的代码中-我检查ID是否已存在的方法是错误的，但下面的方法可行

saveItem（）

函数保存项（名称、值、天数）{
var=”；
如果（天）{
变量日期=新日期（）；
date.setTime（date.getTime（）+（天*24*60*60*1000））；
expires=“；expires=“+date.toutString（）；
}
var mNameList=getCookie（名称）；
如果（mNameList==“”）{
document.cookie=name+“=”+value+expires+“path=/”；
}否则{
var doesItemExists=false；
var partsOfStr=mNameList.split（'-'）；
对于（变量i=0；i”+mNameList+“|currentID->”+value）；
}
}
}

print_r($_COOKIE['savedList']);

function saveItem(name,value,days) {

    var expires = "";
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days*24*60*60*1000));
        expires = "; expires=" + date.toUTCString();
    }

    // Get Cookie
    var mNameList = getCookie(name);

    // If cookie is empty - doesn't exist then create it and put the value given
    if (mNameList == "") {
        document.cookie = name + "=" + value + expires + "; path=/";
    } else {

        // If cookie exists, check if it has already this value, if it doesn't then add oldvalue + new value to that cookie.
        if(mNameList !== value){
            var newValue = mNameList + ';' + value; // "185;65"
            document.cookie = name + "=" + newValue + expires + "; path=/"; 
            console.log("New Value Is : " + newValue);
            var mNameList = getCookie(name); // Το check current cookie get it again
            console.log(mNameList); // Show it - here it shows "185"
        }
        else{
            // Value already exists in cookie - don't add it
            console.log("Are same - mNameList->" + mNameList + "  |   currentID->" + value);
        }
    }
}

function getCookie(cname) {
        var name = cname + "=";
        var decodedCookie = decodeURIComponent(document.cookie);
        var ca = decodedCookie.split(';');

                c = c.substring(1);
            }
            if (c.indexOf(name) == 0) {
                return c.substring(name.length, c.length);
