我的页面上有两个表单，并且有一个按钮可以淡出当前表单并带来另一个。基本上，这两种形式分别是登录和注册。单击按钮时会在两者之间切换。这是发生的事情：

  1. 登录表单是默认的当前表单，我单击按钮将表单更改为注册表单。
  2. 然后我点击重新加载页面的注册表单的提交按钮。
  3. 然后像往常一样出现登录表单。

问题来了，我希望最后是当前表单的表单即使在页面重新加载后也是当前表单。

HTML：

<section id="content">
    <div id="logo" style="margin-left: 0;"></div>
    <div id="container">
        <form id="sign_up" action="login.php" method="post">
            <table style="margin: 0px auto;">
                <tr>
                    <td align="center"> <span style="font-weight: bold;font-size: 2em; color: Gray;">Sign Up</span>

                    </td>
                    <tr>

最简单的事情是使用localStorage或sessionStorage保存表单的状态。如果您想做更多这样的事情，您可能需要考虑寻找一个处理页面状态的框架。

gollowing在每个事件处理程序中设置lastFormin的值。定义处理程序后，如果等于localStorage，它会更改当前形式。localStorage.lastFormsign_up

jQuery(function ($) {

    var $sUp = $("#sign_up"),
        $sIn = $("#sign_in");

    $("#content").on('click', "#sign_up_btn", function () {

        $sIn.stop().fadeOut(800, function () {
            $sUp.fadeIn(800);
        });
        $(this).stop().fadeOut(800, function () {
            $(this).attr({
                value: "Already have an account?",
                id: "sign_in_btn"
            }).fadeIn(800);
        });
        localStorage.lastForm = 'sign_up';
    }).on('click', "#sign_in_btn", function () {

        $sUp.stop().fadeOut(800, function () {
            $sIn.fadeIn(800);
        });
        $(this).stop().fadeOut(800, function () {
            $(this).attr({
                value: "Create An Account",
                id: "sign_up_btn"
            }).fadeIn(800);
        });
        localStorage.lastForm = 'sign_in';
    });

    if (localStorage.lastForm == 'sign_up') {
        $sIn.fadeOut(0);
        $sUp.fadeIn(0);
    }
});
