推荐答案

只需将此函数添加到您的常用脚本函数中并在加载时运行

Just add this function to your common script functions and run on load

$(document).ready(function(){
     setRequired();  
 });

 function setRequired() {
    var $form = $('form');
    $('form').find("[data-val-required]").each(function (index) {
        var $input = $(this); 
        var requiredAsterisk = "<span class=\"required\">*</span>";
        var id = $input.attr('id');
        var $label = $form.find("label[for='" + id + "']");
        if ($label.length > 0) {
            var html = $label.html() + "";
            if (html.indexOf(requiredAsterisk) <= 0) $label.html(html + requiredAsterisk);
        }
    });
};

这是做什么的，它将星号添加到必填字段的标签中.您可以轻松地对其进行更改，以将其添加到输入字段旁边.

What this does it , it adds asterisk to labels of required fields. You can easily change it to add it right next to input fields.

要注意的另一件事是我使用css class = required，因此请记住为此CSS类添加color:red.

Another thing to note is I use css class = required, so remember to add the color:red for this css class.
