JS Rank calculator

Well not to surprise everyone, but the "Rank" does not equal the row you're on, in the top list.
This annoyed me so much that I made a js script that adds the row number to the table.
Code: Select all
if(location.href.substr(-7) == 'top.php'){
alert("this could take up to 10 sec");
var tbody = document.getElementsByTagName('tbody')[document.getElementsByTagName('tbody').length-1].getElementsByTagName('tr');
for(var i=0;i<tbody.length;i++){
tbody[i].innerHTML += "<td>"+i+"</td>";
}
}
It would be a lot nicer, if the mods could build this into the system

I see your point, even though the rank on the challenges section wouldn't be your actual rank.
I think you could speed up your code by avoiding to trigger multiple repaints. Take a look at this:
Code: Select all
(function() {
if(location.href.substr(-7) !== "top.php"){
return;
}
// var date = Date.now();
var tbody = document.getElementsByTagName("tbody");
tbody = tbody[tbody.length - 1];
var clonedTable = tbody.cloneNode(true);
var tRows = clonedTable.getElementsByTagName("tr");
var header = tRows[0];
var row = document.createElement("th");
row.innerHTML = "Rank";
header.appendChild(row);
for (var i = 1, n = tRows.length; i < n; i += 1) {
row = document.createElement("td");
row.innerHTML = i;
tRows[i].appendChild(row);
}
var parent = tbody.parentNode;
parent.replaceChild(clonedTable, tbody);
// console.log(Date.now() - date);
}());
PS: try to encapsulate your code in Self-Invoked-Anonymous (SIA) functions in order to avoid polluting the global object ( window ).
