javascript在firefox中工作,但在ie中不工作-

当ie允许您引用 document.getElementById("authnav") 作为authnav,然后当你给它分配一个字符串时会感到不安。可能显式声明一个局部变量 var authnav 它会起作用还是打算成为一个全局变量?

function add_auth_nav() {
    name = get_cookie("name");
    candidate = get_cookie("candidate");
    if (name) {
        authnav = '<li class="last"><a href="auth/logout">logout</a></li>';
        if (candidate) {
            authnav = authnav + '<li><a href="edit/candidate/' + candidate + '">edit profile</a></li><li><a href="profile/' + candidate + '">view profile</a></li>'
        }
        authnav = authnav + "<li>" + name.replace(/\+/g, " ") + "</li>"
    } else {
        authnav = '<li class="last"><a href="auth/login">login</a></li><li><a href="auth/create_account">create account</a></li>'
    }
    document.getElementById("authnav").innerHTML = authnav
}

结果重现。你能用原始文件替换ie_scripts.min.js文件并检查它是否仍然失败…
