Below, there are four Numbers of PC, arrangement and up and down or so can only choose one, only the selected can drag and drop to place inside, if you don't choose the drag and drop, the present I blind seven or eight also out;
There is a problem, that is, switching arrangement of time, I hope around the PC can return to the initial position, how to do this?
Every time and drag up, dragging the finish will send instructions, send a string: such as "1234", on behalf of the left and right sides, in turn, is 1, 2, 3, 4, no place can send 0
In addition, I hope each time into the page, can remember the location of the PC by drag and drop, back to the value of the background, will tell you that it is around or up and down, and will be back before the string of hair!!
Well, I don't know, why every time I do the project, there is always a difficult problem!
(Vue project!!!!!! )
Help you bosses!!!!!!
