scrollbar

问题 I have a text area in web page which has no scrollbar initially. But when i exceeds the character by 1000, scrollbar is displayed in the textarea. I have to verify the same whether scrollbar is present or not in the textarea when i click or edit the same textarea. 回答1: The client width or height will decrease if a scrollbar is added. So one way would be to check the size before and after. Here's an example (Java) : Long height_before = Long.parseLong(element.getAttribute("clientHeight"));

Each time a message is added, the conversation auto-scrolls to the last item. I am facing a few "strange" issues : When a user writes a rather long message (say, 10 lines), it can then take up almost the whole screen (meaning the space allocated to the ListView ) which is normal of course but then the scrolling is somewhat broken .
