A little script to show the running balance on the chase cc page because they decided it's not important to keep a running balance...
Raw
chase-credit-card-page-has-no-balance.js
(function(){
var amounts = document.querySelectorAll('#Posted tbody .amount');
var balance = Number(document.querySelector('#AccountDetailTable .card-accountdetailcol tbody tr td:nth-child(2)').innerText.substr(1).replace(',',''));
var iii=0;
var amount = '';
var element = null;
var elementsArray = [];
for(iii=0; iii < amounts.length; iii++) {
element = amounts[iii];
amount = element.innerText;
if(amount.substr(0,1) === '-'){
amount = amount.substr(2, amount.length-3);
amount = amount.replace(',','');
amount = amount * -1;
} else {
amount = amount.substr(1, amount.length-2);
amount = amount.replace(',','');
}
elementsArray.push({
'element':element,
'amount':Number(amount),
'order':iii
});
}
elementsArray.map(function(el){
el.element.style.whiteSpace = 'pre';
balance = Number(balance) - Number(el.amount);
el.element.innerHTML = '$'+el.amount.toFixed(2).toString()+' : $'+balance.toFixed(2).toString();
});
})();

This is awesome! Thanks Jeffrey!

All you have to do is open your credit card account activity page and run this script in the js console.

Don't work for me :) I also hate that they don't show running balance. I am switching to BOA for just this reason.

When I run the script, here is an error:
Uncaught TypeError: Cannot read property 'innerText' of null at :3:116 at :31:3

Fixed "Uncaught TypeError: Cannot read property 'innerText' of null at :3:116 at :31:3" with updated selectors:

var amounts = document.querySelectorAll("#activityTableslideInActivity > tbody > tr > td.sm-aligned-right.amount.BODY > span");
var balance = Number(document.querySelector('#activityContainerslideInActivity > div.overview-activity-container.util.print-hide.print-border-none > div > div > div.col-xs-12.recon-header-container > div.current-balance-section > dl > dd:nth-child(2)').innerText.substr(1).replace(',',''));
