有两个选项卡分别命名为“第一个选项卡”和“第二个选项卡”。在第一个选项卡中，“名字”是必填字段，在第二个选项卡中，“电子邮件”是必填字段。当用户尝试单击第二个选项卡时选项卡而不是在第一个选项卡中填写必填字段，应显示警报消息，并且不应允许进入第二个选项卡，除非他在第一个选项卡中填写了所需的信息，第二个选项卡类似。

这是代码

<script type="text/javascript">
    $(document).ready(function() {
        validate();
        $('#first_name, #last_name').change(validate);
    });

    function validate() {
        if ($('#first_name').val().length > 0 &&
            $('#last_name').val().length > 0) {
            $("#second").prop("disabled", false);
            $("#li_second_tab").prop("disabled", false);
        } else {
            $("#second").prop("disabled", true);
            $("#li_second_tab").prop("disabled", true);
        }
