function ke(t,e,n){var r=1,i=null,a=!1,s=0;function u() code example

Example: function l(){return window.performance

function l(){return window.performance&&window.performance.navigation&&window.performance.navigation.type};function m(a,b,c){return!a||!b&&p(a)?0:a.getBoundingClientRect?q(a,b,c,function(e){return e.getBoundingClientRect()}):1}function p(a){if("none"==a.style.display)return!0;if(document.defaultView&&document.defaultView.getComputedStyle){var b=a.getAttribute("data-deferred");b&&a.setAttribute("data-deferred",0);var c=document.defaultView.getComputedStyle(a);c=!!c&&("hidden"==c.visibility||"0px"==c.height&&"0px"==c.width);b&&a.setAttribute("data-deferred",b);return c}return!1}
function q(a,b,c,e){var d=e(a),f=d.left+window.pageXOffset,n=d.top+window.pageYOffset,h=d.width,k=d.height,g=0;if(!b&&0>=k&&0>=h)return g;0>n+k?g=2:n>=(window.innerHeight||document.documentElement.clientHeight)&&(g=4);if(0>f+h||f>=(window.innerWidth||document.documentElement.clientWidth))g|=8;else if(c){for(b=d.left;a&&a!=c;a=a.parentElement)b+=a.scrollLeft;c=e(c);if(b+h<c.left||b>=c.right)g|=8}return g||1};var r,t=["aft","hct","prt","pprt","sct"];function u(a){return(a=v.search.match(new RegExp("[?&]"+a+"=(\\d+)")))?Number(a[1]):-1}function w(a){r.removeEventListener("click",w);a.stopPropagation&&a.stopPropagation()}
