Hello, I am looking for a script that will automatically click a series of buttons(one after the other) when the web page is loaded/refreshed. For example:

1. Click buy
2. If cash > payment click confirm
3. If cash < payment click cancel

The process would need to loop until all "items" are purchased. I usually write in C++ and Java but I have been doing some research in an attempt to write the script myself but I am doing a terrible job at succeeding. I would appreciate any help you can offer.

This is what I have done so far...

var setBtn = document.getElementById("id-button-yes green_btn_big");
setBtn.click(this);

if (cash < cash-neg)
{
var setBtn = document.getElementById("id-button-close confirm-cancel");
setBtn.click(this);
}

if (cash > cash-neg)
{
var setBtn = document.getElementById("id-button-buy green Btn");
setBtn.click(this);
}
