How does PHP set the image hot zone? Hot Zone position not fixed
Title, it's a tricky question.
Need to add the hot zone on the uploaded image, the location is not fixed, the hot zone content can be modified ...
Achieve the same effect as
Hot Zone location can be dragged with the mouse, hot zone content can be modified ...
Do you have any good ideas?
------Solution--------------------
This should be JS things ... You're supposed to be a floating div.
------Solution--------------------
This and PHP do not matter, is not what hot, is the front-end thing.
Basically create a floating layer, plus the JS effect.
Can be sent to the JS area to ask.
------Solution--------------------
The problem is that the JS area will be killed by seconds.
JS is mainly MouseDown MouseMove and MouseUp events
MouseDown the original position when the mouse clicks
MouseMove change the position of the box when the mouse moves
MouseUp a request to the server to record a new location when the mouse is released
