问题 I'm working on a rich text editor for iOS and have most of it working but running into endless problems ensuring that the cursor is visible in the viewport when the user starts typing. I came up with a novel approach: insert a span at the cursor position, scroll to the span, and then remove it. (I haven't gotten to only scrolling if the span is on-screen.) Here's what I wrote: document.addEventListener('keypress', function(e) { jumpToID(); }, false); function jumpToID() { var id =
