2、window-center.js
//定义一些量变
//获得窗口的高度
var windowHeight;
//获得窗口的宽度
var windowWidth;
//获得弹窗的高度
var popHeight;
//获得弹窗的宽度
var popWidth;
//获取滚动条滚动的宽度
var scrollTop;
//获取滚动条滚动的宽度
var scrollLeft;
//延迟时间
var time;
function init(){
windowHeight=$(window).height();
windowWidth=$(window).width();
popHeight=$(".window").height();
popWidth=$(".window").width();
scrollTop=$(window).scrollTop();
scrollLeft=$(window).scrollLeft();
}
//关闭窗口
function closeWindow(){
//找到X的图片，家单击事件，并且关闭窗口
$(".title img").click(function(){
$(this).parent().parent().hide("slow");
});
}
//定义弹出注重窗口的方法
function popCenterWindow(){
clearTimeout(time);
time=setTimeout(function(){
init();
//计算弹出窗口的左上角Y的偏移量
var popY=(windowHeight-popHeight)/2+scrollTop;
var popX=(windowWidth-popWidth)/2+scrollLeft;
//关闭窗口
closeWindow();
//设定窗口的位置
//$("#center").css("top",popY).css("left",popX).show("slow");
$("#center").animate({top:popY,left:popX},500).show();
},80);
}
