好像今天是愚人节

在某博客发现一段模糊JS,果断拿下，哈哈

<script src="//cdn.bootcss.com/jquery/2.2.1/jquery.min.js"></script>

$(document).ready(function(){  
  if(document.cookie.indexOf("lu=") == -1 ){  
    // 延时2秒  
    setTimeout("jQuery.mxblur.interID = setInterval('jQuery.mxblur.begin()', 5)", 1500);  
  }  
});  
  
$.mxblur = {  
    interID : null,  
    num: 0.01,  
    begin : function() {  
        jQuery.mxblur.blur( jQuery.mxblur.num );  
        if(jQuery.mxblur.num > 3) {  
            jQuery.mxblur.num = 0;  
          if(confirm("少年！是不是代码写多了？眼睛模糊了？")) {  
             alert("太累啦，就该歇歇啦，愚人节快乐:)");  
             clearInterval(jQuery.mxblur.interID );  
             jQuery.mxblur.blur(0);  
             document.cookie = "lu=lu";  
          }  
        }  
        jQuery.mxblur.num = jQuery.mxblur.num  + 1 /100;  
    },  
    blur : function() {  
        $("body").css("-webkit-filter","blur("+$.mxblur.num+"px)");
