JS
復制代碼 代碼如下:
//窗口的高度
var windowHeight;
//窗口的寬度
var windowWidth;
//彈窗的高度
var popHeight;
//彈窗的寬度
var popWidth;
//滾動條滾動的高度
var scrollTop;
//滾動條滾動的寬度
var scrollleft;
//延時的時間
var timeout;
function init(){
//獲得窗口的高度
windowHeight=$(window).height();
//獲得窗口的寬度
windowWidth=$(window).width();
//獲得彈窗的高度
popHeight=$(".window").height();
//獲得彈窗的寬度
popWidht=$(".window").width();
//獲得滾動條的高度
scrollTop=$(window).scrollTop();
//獲得滾動條的寬度
scrollleft=$(window).scrollLeft();
}
//定義關閉窗口
function closeWindow(){
$(".title img").click(function (){
$(this).parent().parent().hide("slow");
});
}
//定義彈出窗口的方法
function popcenterWindow(){
//先清空上一次的延遲
clearTimeout(timeout);
timeout=setTimeout(function (){
init();
var popY=(windowHeight-popHeight)/2+scrollTop;
var popX=(windowWidth-popWidht)/2+scrollleft;
$("#center").animate({top:popY,left:popX},300).show("slow");},300);
closeWindow();
}
function popleftWindow(){
clearTimeout(timeout);
timeout=setTimeout(function (){
init();
var popY=windowHeight+scrollTop-popHeight-10;
var popX=scrollleft-5;

closeWindow();
}

var popX=windowWidth-popWidht+scrollleft-10;
