Question

I have a JavaScript function that looks like this:

function recalculateWhatIfCurrentRate(aEle, aChangedLabel, recordID, yearEndCurrentRate) {
    var rate = document.getElementById(aEle).value;
    document.getElementById(aChangedLabel).value = yearEndCurrentRate * (1 + rate);
}

aEle = ctl00_cpMain_tbCurrentRatePercentIncrease_131578
aChangedLabel = ctl00_cpMain_lblScrollCurrentRate_131578
recordId = 131578
yearEndCurrentRate = 100.65

I want to change the actual text of aChangedLabel.

Why doesn’t it change in the DOM?

Answer 1

Label tags don’t have a value attribute, you need to set innerHTML to change the text.
