Chrome: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.Chrome Android: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.Firefox: The behavior of element.getElementsByTagNameNS changed between Firefox 3.5 and Firefox 3.6. In Firefox 3.5 and before, this function would automatically case-fold any queries so that a search for "foo" would match "Foo" or "foo". In Firefox 3.6 and later this function is now case-sensitive so that a query for "foo" will only match "foo" and not "Foo". For more background on this, please see the comment from Henri Sivonen about the change. You can also look at the relevant part of the standard, which states which parts of the API are case-sensitive and which parts aren't.Firefox: Before Firefox 19, this method was returning a NodeList; it was then changed to reflects the spec change.Firefox for Android: Before Firefox 19, this method was returning a NodeList; it was then changed to reflects the spec change.Quest Browser: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.Opera: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.Opera Android: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.Safari: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.Safari on iOS: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.Samsung Internet: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.WebView Android: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.WebView on iOS: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.

This can mean either the content is too short to require a scrollbar or that the element has a CSS style overflow value of visible (non-scrollable).Internet Explorer: In Internet Explorer 5 through 7, if padding is set, the value of scrollHeight is equal to the sum of the top and bottom padding.

Internet Explorer: On Internet Explorer 6 through 8, the event model is different. Event listeners are attached with the non-standard EventTarget.attachEvent method. In this model, there is no equivalent to event.currentTarget and this is the global object. One solution to emulate the event.currentTarget feature is to wrap your handler in a function calling the handler using Function.prototype.call with the element as a first argument. This way, this will be the expected value.
