I wrote my first bookmarklet. It’s pretty cool, if I may say so.

I don't have much time to get into the details. I'll rewrite this later.

If you use Bank of America, you can use this on the page "Bill Pay & e-Bills" This bookmarklet navigates the DOM to find the "Outgoing Payments" table. It cycles through the table and adds a running (declining) total to the table. It's real simple, with now bells & whistles. I wrote it in about 2 hours. But, I always like to get out a calculator and subtract all my scheduled payments from my Available Funds ot see when I would run out of money if I didn't get any paychecks. (It's kind of morbid, but it makes me feel better.) I do this because When ever I am carrying a balance on a credit card, I like to spend nearly every penny each month. It's kind of nerve racking, but it's the best way to make sure those "bargins" that you just HAD to spend credit on remain bargins. (It's amazing how expensive things are when you add in the interest you pay!)

Update:
To use this bookmarklet, just drag this link --> Bank of America Burn Rate Calculator to your bookmark toolbar.

I also cleaned up the code a lot.

Here is the code:
[js]javascript:(
function(){
var getElementsByClassName=function(oElm,strTagName,strClassName){
var arrElements=(strTagName=='*'&&document.all)?document.all:oElm.getElementsByTagName(strTagName);
var arrReturnElements=new Array();
var oRegExp=new RegExp('(^|s)'+strClassName.replace(/-/g,'-')+'(s|$)');
for(var i=0;i if(oRegExp.test(arrElements[i].className)){
arrReturnElements.push(arrElements[i]);
}
}
return(arrReturnElements)
};
var funds=parseFloat(getElementsByClassName(document,'span','payfrommargin')[1].innerHTML.replace(/Avail. Funds $([0-9.,]+).*/,'$1').replace(/,/,''));
var table=getElementsByClassName(document,'table','mod1-bkgd2-hs')[1];
var cells=getElementsByClassName(table,'td','text1a');
for(x=1;x var bill=cells[x].innerHTML.replace(/$([0-9.,]+).*/,'$1').replace(/,/,'');
funds-=bill;
var fundsString=Math.ceil(funds*100).toString();
cells[x].innerHTML='$'+bill+'
$'+fundsString.substring(0,fundsString.length-2)+'.'+fundsString.substring(fundsString.length-2,fundsString.length);
}
}
)
();[/js]

Here it is on one line the way you have to enter in into Mozilla:
[js]javascript:(function(){var getElementsByClassName=function(oElm,strTagName,strClassName){var arrElements=(strTagName=='*'&&document.all)?document.all:oElm.getElementsByTagName(strTagName);var arrReturnElements=new Array();var oRegExp=new RegExp('(^|s)'+strClassName.replace(/-/g,'-')+'(s|$)');for(var i=0;i$'+fundsString.substring(0,fundsString.length-2)+'.'+fundsString.substring(fundsString.length-2,fundsString.length);}})();
