标签： javascript html css input fieldset

我正在使用html和javascript创建一个注册页面，但是我无法在html代码中添加必需的输入标签。下面的代码不起作用：  <input type="email" required name="email" placeholder="Email"/> 这是我的HTML和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 () {
        return false;

我想输入电子邮件和密码，并确认需要输入密码，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，告诉我我的问题是什么，为什么<input type="email" required name="email" placeholder="Email"/>中的必填项和type =“ email”无法使用？ 此外，很抱歉在我的问题中写错了。

<input>标签是自动关闭标签，不应关闭/。有关更多详细信息，请参见here。

像这样尝试：
<input type="email" required name="email" placeholder="Email">

答案 1 :(得分：0)

当我搜索并了解使需要归档的唯一方法时，就是使用javascript获取值并进行检查，如果它的格式不正确，请让用户更改输入，否则提交用户输入。 了解更多信息： Check Html Values With JavaScript
