Is there a simple way to get the current URL from an iframe?

The viewer would going through multiple sites. I\'m guessing I would be using something in javascript.<

If you're inside an iframe that don't have cross domain src, or src is empty:

Then:

function getOriginUrl() {
    var href = document.location.href;
    var referrer = document.referrer;
    // Check if window.frameElement not null
    if(window.frameElement) {
        href = window.frameElement.ownerDocument.location.href;
        // This one will be origin
        if(window.frameElement.ownerDocument.referrer != "") {
            referrer = window.frameElement.ownerDocument.referrer;
        }
    }
    // Compare if href not equal to referrer
    if(href != referrer) {
        // Take referrer as origin
        return referrer;
    } else {
        // Take href
        return href
    }
}

If you're inside an iframe with cross domain src:

Then:

function getOriginUrl() {
    var href = document.location.href;
    var referrer = document.referrer;
    // Detect if you're inside an iframe
    if(window.parent != window) {
        // Take referrer as origin
        return referrer;
    } else {
        // Take href
        return href;
    }
}
