如何在需要的字段集标签中制作输入标签？
How to make input tag in fieldset tag required?
使用 html 和 java 脚本我正在尝试创建一个注册页面，但我无法在 html 代码中创建所需的输入标签。下面的代码不起作用：
<input type="email" required name="email" placeholder="Email"/>
这是我的 html 和 css 以及 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;
})

我想创建电子邮件和密码并确认密码要求输入，这样用户就无法在不填写此表单的情况下转到下一个字段集。
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
<input> 标签是一个自关闭标签，不应有 / 来关闭。有关详细信息，请参阅 here。
这样试试：
<input type="email" required name="email" placeholder="Email">
根据我的搜索和了解，唯一需要提交的方法是使用 javascript 获取值并检查它，如果格式不正确，请用户更改输入，否则提交用户输入。
