如何将fieldset标签中的input标签设为必填？

问题描述 投票：0回答：3

使用 html 和 javascript 我正在尝试制作一个注册页面，但我无法制作 html 代码中所需的输入标记。下面的代码不起作用： 

<input type="email" required name="email"  placeholder="Email"/>
这是我的 html、css 和 java 脚本代码：

//jQuery time
    var current_fs, next_fs, previous_fs; //fieldsets
    var left, opacity, scale; //fieldset properties which we will animate
    var animating; //flag to prevent quick multi-click glitches

    $(".next").click(function () {
        if (animating) return false;
        animating = true;

        current_fs = $(this).parent();
        next_fs = $(this).parent().next();

        //activate next step on progressbar using the index of next_fs
        $("#progressbar li").eq($("fieldset").index(next_fs)).addClass("active");

        //show the next fieldset
        next_fs.show();
        //hide the current fieldset with style
        current_fs.animate({opacity: 0}, {
            step: function (now, mx) {
                //as the opacity of current_fs reduces to 0 - stored in "now"
                //1. scale current_fs down to 80%
                scale = 1 - (1 - now) * 0.2;
                //2. bring next_fs from the right(50%)
                left = (now * 50) + "%";
                //3. increase opacity of next_fs to 1 as it moves in
                opacity = 1 - now;
                current_fs.css({
                    'transform': 'scale(' + scale + ')',
                    'position': 'absolute'
                });
                next_fs.css({'left': left, 'opacity': opacity});
            },
            duration: 800,
            complete: function () {
                current_fs.hide();
                animating = false;
            },
            //this comes from the custom easing plugin
            easing: 'easeInOutBack'
        });
    });

    $(".previous").click(function () {
        if (animating) return false;
        animating = true;

        current_fs = $(this).parent();
        previous_fs = $(this).parent().prev();

        //de-activate current step on progressbar
        $("#progressbar li").eq($("fieldset").index(current_fs)).removeClass("active");

        //show the previous fieldset
        previous_fs.show();
        //hide the current fieldset with style
        current_fs.animate({opacity: 0}, {
            step: function (now, mx) {
                //as the opacity of current_fs reduces to 0 - stored in "now"
                //1. scale previous_fs from 80% to 100%
                scale = 0.8 + (1 - now) * 0.2;
                //2. take current_fs to the right(50%) - from 0%
                left = ((1 - now) * 50) + "%";
                //3. increase opacity of previous_fs to 1 as it moves in
                opacity = 1 - now;
                current_fs.css({'left': left});
                previous_fs.css({'transform': 'scale(' + scale + ')', 'opacity': opacity});
            },
            duration: 800,
            complete: function () {
                current_fs.hide();
                animating = false;
            },
            //this comes from the custom easing plugin
            easing: 'easeInOutBack'
        });
    });

    $(".submit").click(function () {

我想创建电子邮件和密码，并确认密码所需的输入，以便用户在不填写此表单的情况下无法进入下一个字段集。 请帮助我并告诉我我的问题是什么以及为什么 required 和 type="email" 在 

<input type="email" required name="email"  placeholder="Email"/>
中不起作用？ 另外，很抱歉我的问题写错了。

据我搜索和理解，使归档成为必需的唯一方法是使用 javascript 获取值并检查它，如果它没有正确的格式，则让用户更改输入，否则提交用户输入。 了解更多信息： 使用 JavaScript 检查 Html 值

<input>
标签是一个自关闭标签，不应有 
/
来关闭。请参阅此处了解更多详情。

尝试这样：

<input type="email" required name="email"  placeholder="Email">

输入标签有一个名为“required”的属性。如果输入标签具有该属性，则必须在提交之前填写。
