如何在html / javascript中实现登录弹出窗口

Basically, I want to create a login popup like the one that a lot of routers have to get access to the setup page: 如何在html / javascript中实现登录弹出窗口

基本上,我想创建一个登录弹出窗口,就像许多路由器必须访问设置页面一样:

is it possible to implement this on an html file at all or is it only for server based access?

是否可以在html文件上实现这一点,还是仅用于基于服务器的访问?

You should probably read this:

你应该读这个:

http://en.wikipedia.org/wiki/Basic_access_authentication

and this:

http://www.php.net/manual/en/features.http-auth.php

In short words:

简而言之:

1 You can invoke this popup using special headers.

1您可以使用特殊标题调用此弹出窗口。

2 You can invoke this popup only before page starts loading.

2您只能在页面开始加载之前调用此弹出窗口。

3 You can't do this using html+js only.

3您不能仅使用html + js执行此操作。

4 You can't invoke prompt windows with password-like inputs with pure js.

4您无法使用纯js调用类似密码的输入的提示窗口。

UPD: That question was answered, having the following comment from author to main post in mind:

UPD:这个问题得到了回答,从作者到主要帖子的评论如下:

Is there a way to get the exact popup in the picture? i.e its a browser based popup not styled?

有没有办法在图片中获得确切的弹出窗口?即它的浏览器弹出窗口没有样式?

I never stated, that one can not create SIMILAR styled popup with js+html. The answer was about invoking the exact popup.

我从来没有说过,不能用js + html创建SIMILAR样式的弹出窗口。答案是关于调用确切的弹出窗口。

Actually, you CAN do it with HTML + JavaScript on client-side at "any moment" without refreshing the page...

实际上,您可以在“任何时刻”在客户端使用HTML + JavaScript执行此操作而无需刷新页面...

if(showhide == "show"){
    document.getElementById('popupbox').style.visibility="visible";
}else if(showhide == "hide"){
    document.getElementById('popupbox').style.visibility="hidden"; 
}
}
</script>
</head>
<body>

<div id="popupbox"> 
<form name="login" action="" method="post">
<center>Username:</center>
<center><input name="username" size="14" /></center>
<center>Password:</center>
<center><input name="password" type="password" size="14" /></center>
<center><input type="submit" name="submit" value="login" /></center>
</form>
<br />
<center><a href="javascript:login('hide');">close</a></center> 
</div> 

<p>
Some text
</p>
<p>
Some more text
</p>
<p><a href="javascript:login('show');">login</a></p>
</body>
</html>

I also solved the issue about sending vars from JavaScript to PHP without refreshing, and it's working just fine so far, loading an entire SQL query-based website with virtually no pages refresh (which allowed me to have a heavier header animation, fonts and other stuff, once it's loaded just one time).

我还解决了将vars从JavaScript发送到PHP而不刷新的问题,到目前为止工作得很好,加载整个基于SQL查询的网站几乎没有页面刷新(这使得我有更重的标题动画,字体和其他东西,一旦加载一次)。

What you need is a form based authentication defined in your HTML. Something like this:

您需要的是HTML中定义的基于表单的身份验证。像这样的东西:

<form method="post" action="/login">
  <input type="text" name="username">
  <input type="password" name="password">
  <input type="submit" value="Log In">
</form>

and you would need a server to handle the POST action, and perform authentication.

并且您需要服务器来处理POST操作,并执行身份验证。
