问题 This question already has answers here : ipad safari: disable scrolling, and bounce effect? (16 answers) Closed 2 years ago .

问题 Here's the site: http://joshnh.com/ Basically, I have a few elements that are super wide so that they look as though they are coming out from the right hand side of the screen.

问题 C#3.0,.net framework 3.5 I am drawing ( using the draw method in the graphics class) a lot of solid rectangles on a windows form vertically.

问题 I'm trying to have a scrolling MapView inside of a RecyclerView, therefore I'm setting requestDisallowInterceptTouchEvent() before and after the TouchEvent. The odd thing is: this does work if I set it in the dispatchTouchEvent() method, but it doesn't work if I do the same in the onTouchEvent() method. Can somebody explain why I cannot set this in onTouchEvent() ? Working: public class WorkingScrollableListItemMapView extends MapView { // constructors @Override public boolean

问题 I'm making a portfolio website that contains a simple dropdownlist and one big GIF image in a div (10659px × 6850px). As I intended, when you make selections from the list, you jump to certain anchor points on the page using a simple javascript that's being activated onChange. The html: <div id="background"> <img src="img/background.gif" width="10659" /></div> <select id="dropdownlist" onChange="jumpScroll(this.value);"> <option alt="selected works" value="0">Selected works:</option> <option
