Just use window.scrollTo(x, y).

where i have to use this statement : window.scrollTo(x, y).


thanks

That only tells the window to scroll.

Since you already have drag and drop capabilities, then you must have access to the mouse coordinates. If the mouse Y coordinate is about to go off the screen, tell the window to scroll up about 50 pixels.

hey thanks for reply, i used like this window.scrollTo(0,5); it always move to top of the page. If i want to move in between the page how can i set the coordinates.

thanks ...

The two numbers are the X and Y coordinates of the page. Just specify the coordinates to which you want to scroll.

[Hint: usually relative to some "current" position....]

Y coordinate every time will changed. i want to move the scroll bar based on the mouse like we scroll the mouse up and down. Like that when i drag the selected element with mouse it should move scrollbar with the mouse.

thanks..

Not in JavaScript. It is always from the top of the page. The offset is always controlled by scrolling offset methods.

So why not just track the mouse coordinates and then set the scrollTo accordingly?

The parameter to ScrollTo() is always absolute...no disagreement...

HOW those parameters are CALCULATED is usually based on a combintation of the current position and the desired amount of movement (A "relative" value).
