我创建了这样一个if语句:
if (lehrling == null)
{
ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('Bitte überprüfen Sie Ihren URL Key');", true);
//Blur Website
//Disable Website
}
如果语句为真，则显示警告。我还想模糊网站，不让它可点击…所以你不能访问网站的任何内容。当我点击警告信息时，网站应该关闭....
我怎么能做到这一点?有什么好的js方法来做到这一点吗?也许jquery ?
禁止访问用户的注意事项
如果你想让网站不被某些用户打开，如果他们被拒绝访问，那么模糊网站并不是一个最佳实践，因为用户将能够看到网页源代码或通过开发工具删除模糊。为此，您应该将用户重定向到服务器端拒绝访问的页面。在PHP中，你可以这样做
if($denied == true) { header("Location: /access-denied.html"); }
或
if($denied == true) { die('You cannot access this page because...'); }
或甚至显示您想要的警告框并关闭窗口，而不显示页面，因为，正如我所说的，将源代码提供给您不想访问该页面的用户是一种不好的做法。
然而，模糊网站(一般示例)
在阅读了我的笔记之后，如果你仍然想这样做，我已经创建了，在开始的时候，一个一般情况下的例子，以便能够看到演示(你的特别代码，修改，可以在答案的底部找到)。在演示模式下窗口没有关闭
$("#blur").click(function() {
$('body').addClass('blur_site');
alert("Good bye!");
window.close();
});.blur_site {
filter: blur(1px);
-webkit-filter: blur(1px);
-o-filter: blur(2px);
-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
pointer-events: none;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button id="blur">Blur</button>

</b>模糊网站(修改原始代码)
if (lehrling == null)
{
$('body').addClass('blur_site');
ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('Bitte überprüfen Sie Ihren URL Key');", true);
window.close();
}
并添加到你的CSS:
.blur_site {
filter: blur(1px);
-webkit-filter: blur(1px);
-o-filter: blur(2px);
-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
pointer-events: none;
}
注意这段代码使用的是JQuery
一个可能的直接解决方案。
var dialog = $("div.Curtain");
function showDialog(content) {
$("div#DialogContent", dialog).html(content);
dialog.show();
}
$("div.Dialog").on("click", "a.Button", function(e) {
e.preventDefault();
var button = $(this);
if (button.attr("id") == "CancelButton")
dialog.hide();
else
alert("redirect somewhere or do other staff");
});html, body {
width: 100%;
height: 100%;
}
div.Curtain {
z-index: 1;
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
background: rgba(0, 0, 0, .3);
display: none;
}
div.Dialog {
position: fixed;
z-index: 2;
width: 300px;
background: white;
padding: 40px;
}
div.Dialog a.Button {
display: block;
width: 200px;
height: 40px;
line-height: 40px;
text-align: cente;
margin: 10px;
background: blue;
color: white;
text-decoration: none;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
This is the content of the website.
<a href="javascript:showDialog('dialog content');">show the dialog</a>
</div>
<div class="Curtain">
<div class="Dialog">
<!--A way can be to put the content of the dialog in a hidden div and showing it in front of a curtain when done.-->
<div id="DialogContent"></div>
<a class="Button" href="#" id="OkButton">Ok</a>
<a class="Button" href="#" id="CancelButton">Cancel (redirect)</a>
</div>
</div>你可以使用JQuery或Bootstrap这样的框架来使用它们的模态窗口来实现这一点。与Javascript结合使用，你也可以关闭当前的浏览器窗口。
- 引导模式示例:http://www.w3schools.com/bootstrap/bootstrap_modal.asp
- Jquery模式示例:https://jqueryui.com/dialog/#modal-message
- Javascript关闭浏览器:window.close();
这就是你需要的所有信息。成功!
