Question

我正在开发一个使用Firebase作为我的后端的网站，用户已登录但登录后我无法转到下一页我需要它来取用户，它只是刷新登录页面。我有点教这个JavaScript，所以任何帮助都会很棒。

提前致谢。

登录页面：

<div class="container">
        <div class="row">
            <div class="col-md-3"></div>

            <div class="col-md-6">


                <p>Enter an email and password below and either sign in to an existing account or sign up</p>

                <input class="mdl-textfield__input" style="display: inline; width: auto;" type="text" id="email" name="email" placeholder="Email" />
                &nbsp;&nbsp;&nbsp;
                <input class="mdl-textfield__input" style="display: inline; width: auto;" type="password" id="password" name="password" placeholder="Password" />
                <br />
                <br />

为什么不呢。 document.location.href =＆＃39; ＆＃39;而是在widows.location上。＆＃34;警报（＆＃34;欢迎＆＃34）; window.location =＆＃39; ../ UserPages / UserIndex.aspx＆＃39 ;;

            }  "

登录后，页面刷新而不是转到下一页
