firefox控制台中显示一个框架文档的字符编码未声明。该文档可能与非框架时的显示效果不同，怎么修改呢
程序代码："http://www.var myImages ={length:4,0:'style/style.css',1:'style/basic.css',2:'image/navbar.png',3:'image/slideshow.gif'};
var qtool = {};
function loadImages(){
var isIE=/*@cc_on!@*/0,
//isFF = !!document.getBoxObjectFor || 'mozInnerScreenX' in window,
isOP = !!window.opera && !!window.opera.toString().indexOf('Opera'),
res = Array.prototype.slice.call(myImages);
if(isIE||isOP)
{
qtool.preload = (function(){
window["preimgs"] = {};
var seri=1;
return function(){
var res=Array.prototype.slice.call(myImages),
i=res.length;
while(i--)
{
var img = window["preimgs"][i] = new Image();
img.onload = img.onerror = function() {window["preimgs"][this.serial]=null;delete window["preimgs"][this.serial];};
img.src = res[i];
img.serial = seri++;
}
};
})();
}
/*else if(isFF)
{
}*/
else
{
qtool.preload = function()
{
var res = Array.prototype.slice.call(myImages),
i=res.length;
if(document&&document.body)
{
while(i--)
{
var obj = document.createElement('object');
obj.data = res[i];
obj.width = obj.height = 0;
obj.onload = function() {obj.style.display="none";};
obj.onerror = function() {obj.style.display="none";};
document.body.appendChild(obj);
}
}
}
}
//TODO 支持HTML草案的Link Prefetch
//http://www.
qtool.preload.apply(qtool,res);
}
