试图学习ASP.net MVC的基础知识,并且不能理解为什么我的客户端验证不起作用.

我在我的web.config文件中都有这个(1是全局1在views文件夹中)

<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />

我在_layout.cshtmlfile中有这个

@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/Scripts/jquery.validate.unobtrusive.min.js")
@Scripts.Render("~/Scripts/jquery.validate.min.js")

这是我的测试注册的视图模型:

public class RegisterVM
    {
        [Required(ErrorMessage="Username Required")]
        public string username { get; set; }

        [RegularExpression(@"((?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{6,20})")]
        [Required(ErrorMessage="Password Required")]
        public string password { get; set; }

        [Compare("password", ErrorMessage="Passwords do not match")]
        public string passwordConfirm { get; set; }
    }

这是我的HTML

@using(@Html.BeginForm()){

    @Html.LabelFor( model => model.username)
    @Html.EditorFor( model => model.username)
    @Html.ValidationMessageFor( model => model.username)<br />

    @Html.LabelFor( model => model.password)
    @Html.PasswordFor( model => model.password)
    @Html.ValidationMessageFor( model => model.password)<br /> …

我试图通过为标签指定一个类'brtop'来轻推电子邮件标签并输入一点.

.brtop 只是增加了一个上边距.

似乎没有做任何事情,我做错了什么？

var mdflag;
var count = 0;

document.addEventListener("mousedown",mdown,false);
    document.addEventListener("mouseup",mup,false);
}


function mdown()
{
    mdflag=true;
    while(mdflag)
    document.getElementById("testdiv").innerHTML = count++;

}
function mup()
{
    mdflag = false;
}

我想要在鼠标停止时运行代码,我无法找到任何建议我可以做的同时(mousedown)所以我尝试为mousedown制作一个标志,这是在鼠标上重置然而我相信while循环是什么导致我陷入无限循环.

有什么建议可以帮助我实现的目标吗？

当我这样做时,我正试图让我的画布适合页面:

ctx.canvas.width = window.innerWidth;
ctx.canvas.height = window.innerHeight;

它只是水平和垂直,这是添加滚动条.它过去的大小是关于滚动条的大小在它们偶然出现之前被考虑(只是一个猜测)这是什么发生的,我将如何让它适合没有滚动条的页面.
