jquery 设置页面标签水平垂直居中显示

$(function(){
    $(window).resize();
});
$(window).resize(function(){
    $(".center-in-center").css({
        position: "absolute",
        left: ($(window).width() - $(".center-in-center").outerWidth())/2,
        top: ($(window).height() - $(".center-in-center").outerHeight())/2

});

//标签要有一个初始的尺寸。

2.打开新窗口居中显示

  var openUrl = ;//弹出窗口的url  
var name = "";
      var iWidth=400; //弹出窗口的宽度;  
      var iHeight=400; //弹出窗口的高度;  
      var iTop = (window.screen.availHeight-30-iHeight)/2; //获得窗口的垂直位置;  
      var iLeft = (window.screen.availWidth-10-iWidth)/2; //获得窗口的水平位置;  
   window.open(openUrl,name,"height="+iHeight+ ",width=" +iWidth+ ",top= " +iTop+ ",left="+iLeft+ ",toolbar=no,menubar=no,scrollbars=no, resizable=no,location=no, status=no");
