试图获得存在的cookie

我正在尝试使用以下代码获取存在cookie:

  function readCookie(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);
        console.log(c);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}

我有cookie名称,但我总是得到NULL。

我在开发者工具(https://developers.google.com/web/tools/chrome-devtools/manage-data/cookies

中看到了Cookie

document.cookie""

试试这个

function readCookie(name){
    var nameEQ = name+"=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        if (c.indexOf(nameEQ) !=-1) return c.substring(nameEQ.length,c.length);
    }
    return null;
}
document.cookie="name=sagar;expire=";
console.log(readCookie(`name`));
