从单击的div中心将弹出窗口缩放到中心屏幕 [英] Zoom pop-up to center screen from center of clicked div

问题描述

对于jQuery和其他所有应用程序我都是新手，如果我在任何地方都做错了，请原谅我.

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

我有一个要求，即有多个可点击的框，当您单击任何框时，它会像弹出窗口一样打开，但是以这种方式看起来好像是从那个特定的被单击框出来的，并且如果您要关闭打开的弹出窗口，它将缩小到被单击的框(看起来就像在被单击的框内一样)

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)

推荐答案

对于jQuery新手来说，这是一个复杂的问题，但这是一个解决方案.

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

注意:匆匆忙忙，暂时没有时间来计算正确的坐标，以将弹出框的死点定位在屏幕上-此示例放置了框的死点的上/左角屏幕上.我留给您算出将框的中心放在屏幕中心的坐标-，如果您在解决方案中留下评论，并附带指向修订的jsFiddle的链接，我将不胜感激.

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演示

 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;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div id="overlay"></div>
<div id="msg">Click on me to minimize again</div>

<div id="d1" class="dd clickable">Div One</div>
<div id="d2" class="dd clickable">Div Two</div>
<div id="d3" class="dd clickable">Div Three</div>
<div id="d4" class="dd clickable">Div Four</div>
