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 username = getCookie("user");
    if (username != "") {
        $(".dropdown").append("<div id='uname' style='font-style: bold;'>" + username+ "</div>");
        console.log(username);
    } else {
        window.location.replace("../index.php");
    }
}

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 + ";path=/";
}

setCookie("user", "EricF", 1);
checkCookie();

美好的一天，通过cookie设置用户名的过程，我想在导航栏中显示用户名（使用Bootstrap）。我将此代码放入导航栏：

            <ul class="nav navbar-nav navbar-right">
              <li><a href="#">Ver. 1.0.0 - Dated: 2017-01-30 </a></li>
                <li class="dropdown">
                  <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">
                     <div id="uname" style="font-style: bold;"></div>
                  <span class="caret"></span></a>
                  <ul class="dropdown-menu">
                    <li><a data-toggle="tab" href="frames/help.html">Help</a></li>
                    <li><a data-toggle="tab" href="frames/about.html">About</a></li>
                    <li><a data-toggle="tab" href="#logout">Logout</a></li>
                  </ul>
              </li>
            </ul>

在Javascript（jQuery）中，我有这个：

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 username = getCookie("user");
    if (username != "") {
        $("#uname").text(username);
        console.log(username);
    } else {
       // Redirect to login
        window.location.replace("../index.php");
    }
}

checkCookie();

我尝试在空<div id="uname" style="font-style: bold;"></div>之间插入用户名，但它没有显示......而且，是的，控制台为我提供了用户名！有人可以帮忙吗？在此先感谢：）

用jQuery和Bootstrap填充空div
