Asp.net Mvc 表单验证(气泡提示)

将ASP.NET MVC或ASP.NET Core MVC的表单验证改成气泡提示:

//新建一个js文件(如:jquery.validate.Bubble.js),在所有要验证的页面引用
(function ($) {
    
    $("form  .field-validation-valid,form .field-validation-error")
    .each(function () {
        var tip = $(this);
        var fname = tip.attr("data-valmsg-for");
        var input = $("#" + fname);
        var vgName = "vg" + fname;
        $("<span class='vg' id='" + vgName + "'></div>").insertBefore(input);
        input.appendTo("#" + vgName);
        tip.appendTo("#" + vgName);
        
    });

})(jQuery);

.control-label {display: block; text-align:left;}
@media (min- 768px) {
    .control-label {
        display:inline-block;min-width:75px; text-align:right;        
    }
}

.vg { display: block; position: relative; overflow: visible; }
.vg .form-control{display:block;max-width:inherit;}
@media (min- 768px) {
    .vg { display: inline-block; }
}

 .vg .field-validation-error {
        position: absolute; bottom: 101%; min-height: 30px; z-index: 999; right: 0px;
        background: #ff0000; color: #FFFFFF; padding: 0px; border: 7px solid #ff0000;
        border-radius: 0.7em; font-size: 9pt; font-family: "Helvetica Neue", Helvetica,微软雅黑, Arial, sans-serif;
        max-height: 3.7em; overflow: visible; text-overflow: ellipsis; line-height: 1.3em; opacity: 0.7;
    }

.vg .field-validation-error::after {
            content: " "; position: absolute; width: 1px; height: 1px; border: 14px solid blue; border-color: transparent;
            border-top-color: #ff0000; display: block; overflow: visible; top: 100%; right: 0px;
}

//新建一个css文件(如:jquery.validate.Bubble.css),在所有要验证的页面引用

然后您的表单不用做任何修改就可以正常显示了(control-label 相关的样式可以不要(1-6行)).
