从单击的div中心将弹出窗口缩放到中心屏幕

Question

I am new for jQuery and all, forgive me If I am wrong anywhere.

I have a requirement, that there are multiple click-able boxes, as soon as you click on any box it will open like pop-up but in such a manner It will look like it is coming out from that particular clicked box, and if you will close the opened pop-up, it will shrink to the clicked box(look like it is going inside the clicked box)

Answer 1

This is a bit of a complex question for a jQuery novice, but here is a solution.

Caveat: In a rush and don't have time just now to calculate the correct coords to position the pop-up box dead center of screen - this example puts the top/left corner of the box dead center of screen. I leave it to you to work out the coordinates to put center of box in center of screen -- and I would appreciate it if you would leave a comment with link to revised jsFiddle with your solution.

jsFiddle Demo

  var xx, yy, mPos = { x: -1, y: -1 }; //mouse position $(document).mousemove(function(event) { mPos.x = event.pageX; mPos.y = event.pageY; }); $('.dd').click(function(){ xx = mPos.x; yy = mPos.y; $('#msg').css({top:mPos.y+'px',left:mPos.x+'px'}).animate({ height: '400px', width: '500px', left: $(window).width() / 2, top: $(window).height() / 2 },500,function(){ //use a callback to show overlay ONLY when animation finished $('#overlay').show(); }); }); $('#msg').click(function(){ $('#overlay').hide(); $('#msg').animate({ height: '0px', width: '0px', left: xx+'px', top: yy+'px' },500); }); 

 #overlay{position:absolute;top:0;left:0;height:100%;width:100%;background:black;opacity:0.7;z-index:1;display:none;} #msg{position:absolute;height:0;left:0;background:wheat;overflow:hidden;z-index:2;} .dd{height:30px;width:100px;margin:30px;padding-top:25px;border:1px solid orange;} .clickable{cursor:pointer;}
