Question

我有一个我用jQuery设计的索引页面动画，它不一致地表现相同（所有部分都应该以逻辑方式居中）。可以在http://cspsolutions.ca/Maxxim查看。如果你刷新它几次，你会发现它并不是始终在谷歌浏览器的同一位置结束，但在所有其他浏览器中都能正常工作。要在Chrome中查看此问题，页面需要刷新几次。任何帮助将不胜感激，代码列在.js文件下面。

// JavaScript Document

$(document).ready(function() {

$(".intro-no-js").css("visibility","hidden");
$(".intro-javascript").css("visibility","visible");

//defines how max should be animated
jQuery.fn.maxanimate = function () { 
this.css("position","absolute"); 

    var t = (($(window).height() - this.outerHeight()) / 2) + $(window).scrollTop(); 

    var l = (($(window).width() - this.outerWidth()) / 2) + $(window).scrollLeft(); 

    $(this).animate({
        top: t,
        left: l-79.5
    }, 1000);

    return this; 
} 


//defines how xim should be animated
jQuery.fn.ximanimate = function () { 
this.css("position","absolute"); 

    var t = (($(window).height() - this.outerHeight()) / 2) + $(window).scrollTop(); 

    var r = (($(window).width() - this.outerWidth()) / 2) + $(window).scrollLeft(); 

    $(this).animate({
        top: t,
        left: r+78.5
    }, 1000);

//defines how top arrows should be animated

    var t = (($(window).height() - this.outerHeight()) / 2) + $(window).scrollTop(); 
    var l = (($(window).width() - this.outerWidth()) / 2) + $(window).scrollLeft(); 

    $(this).animate({
        top: t-25,

//defines how bottom section should be animated
jQuery.fn.animatebottom = function () { 
this.css("position","absolute"); 

    var b = (($(window).height() - this.outerHeight()) / 2) + $(window).scrollTop(); 
    var l = (($(window).width() - this.outerWidth()) / 2) + $(window).scrollLeft(); 

    $(this).animate({
        bottom: b-27,

//max starting co-ordinates
var maxl = $(window).width() - 157; 
var maxt =  ($(window).height() - $("#intro-max").outerHeight()) / 2; 

//xim starting co-ordinates
var ximr = $(window).width() - 159; 
var ximt = ($(window).height() - $("#intro-xim").outerHeight()) / 2; 

//arrows starting co-ordinates
var al = (($(window).width() -  $("#intro-xim").outerWidth()) / 2) + $(window).scrollLeft()+ 35; 
var at = 0; 

//bottom of logo starting co-ordinates
var bl = (($(window).width() -  $("#intro-xim").outerWidth()) / 2) + $(window).scrollLeft()-90;
var bt = 0;

//set initial co-ordinates for all divs
$("#intro-arrows").css({position: "absolute",top: at,left: al});

$("#intro-xim").css({position: "absolute",top: ximt,left: ximr});

//lets bring it all to life!
$("#intro-max").maxanimate();

//refresh window if resized
$(window).bind('resize',function(){

}); 


$("#design").click(function() { 
    window.location.href = "main.html?page=2&sel=1";  
    return false;//Just in case if it is a link prevent default behavior 
}); 


});

问题是元素虽然在最初运行javascript时确实存在于DOM中，但实际上并没有在浏览器中呈现，因此还没有实际的宽度或高度。展示位置已关闭，因为您使用的outerWidth和outerHeight在页面加载时错误地返回0。

解决此问题的一种简单方法是不在$(document).ready上调用初始动画，而是在$(window).load上调用元素渲染和下载图像后触发。{/ p>

动画与结果Jquery不一致
