Topic: Ideas and script requests / Tab key moves to text input fields only?

You can accidentally focus hidden fields this way. I think it's better to check for inputs of type text. XPath will do the job just fine:

//input[@type='text'][0]

Greasemonkey scripts can't read local files but they can create HTML that links to a local file.

I agree that a preview function would be useful. Is there a way to contribute to this site?

xpathExec

function xpathExec(xpath, func) {
	var result = document.evaluate(xpath, document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null);
	for (var i = 0; i < result.snapshotLength; i++) {
		if (result.snapshotLength == 1) return func(result.snapshotItem(i), arguments[2], arguments[3]);
		else func(result.snapshotItem(i), arguments[2], arguments[3]);
	}
}
// example
xpathExec("//td[@class='ebcPpl']", replaceInItem, "PayPal", "PP");

Or even shorter:

var totalgold = 0, tds = document.getElementByTagName("td");
for (var i = 40; i <= 160; i += 5) {
  totalgold += parseInt(tds[i].textContent.replace(/[^0-9]/ig, ""), 10);
}
alert(totalgold);
