Set position of draggable div

问题

I'm doing a little application using jQuery and JQuery ui.

I've defined a dragable div, and it works perfectly, but I want to set the position of the div when a click a button...

I read here in stackOverflow to do this:

element.position().top = topUserDefined;
element.position().left = leftUserDefined;

I did an alert of element.position().top before and after this assignment and the new value it's not assigned, it keeps the original one...

Any Idea??? Thanks!

回答1:

.position() gets the position. It doesn't set the position. It actually uses element.offsetLeft and element.offsetTop (compared to element.offsetParent position) those are read only.

Change inline CSS value to move your element:

element.css({'top': 10, 'left' : 20})
