contentscript.js
Pages initially load at fully opacity, and fade out to their appropriate level when the traceroute has completed.
// make xhr request to traceroute counting script; return hop count converted to a float
// thanks to Jonas for ajax syntactic sugar
function getTraceRouteCount(callback) {
var currentUrl = window.location.host;
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function(data) {
if (xhr.readyState == 4) {
if (xhr.status == 200) {
var data = xhr.responseText;
callback(data);
} else {
callback(null);
}
}
}
var url = "http://pzwart3.wdka.hro.nl/~egreenhalgh/cgi-bin/hopsToPercent2.py?url="+ currentUrl;
xhr.open('GET', url, true);
xhr.send();
};
// begin to fade out the page
waitUntilExists(document,function(){
$("body").fadeTo(9000, 0.7);
});
// when xhr request returns data, stop page fade and set to appropriate opacity
function opacityFade(data) {

//console.log(data);
}
}
