呵呵，有三处错误！！！
1、2处双引号匹配错误，
2、不是，document.msgblk.document.write而是：document.getElementById('msgblk').innerHTML =
帮你做好了，看效果吧，谢谢哦，多给点分数吧，^_*

追问

没有效果！你这个没有该对！

追答

悲剧啊，我再 Firefox 下面测试了。难道你是IE，？我修正一下

var speed = 20;
var cycledelay = 1000;
var maxsize = 48;
var thismsg2 = new initArray(
"从小到大... ...还会从大到小... ...", 
" 可以加粗加斜加链接... ...", 
"还可以加图片:)", 
"嘿嘿... ...酷吧！");
var x = 0;
var y = 0;
var thismsg,
size;
var esize = "";
function initArray() {
    this.length = initArray.arguments.length;
    for (var i = 0; i ');
function big() {
    thismsg = thismsg2[y];
    if (x ';

        document.getElementById('msgblk').innerHTML = size + "" + thismsg + "" + esize;
        document.getElementById('msgblk').style.fontSize = x + 'px';

}
function small() {
    if (x > 1) {
        x--;
        setTimeout("small()", speed);

    }
    else {
        setTimeout("big()", cycledelay);
        y++;
        if (y > thismsg2.length - 1) y = 0;

    }

    msgblk.innerHTML = "" + thismsg + "";
    msgblk.style.fontSize = x + 'px';

}
setTimeout("big()", speed);

var getPositionLite = function(el) {
    var x = 0,
    y = 0;
    while (el) {
        x += el.offsetLeft || 0;
        y += el.offsetTop || 0;
        el = el.offsetParent
    }
    return {
        x: x,
        y: y
    }
};

是 IE 兼容性问题。楼上已经弄好了，但是伐不出去代码了，他让我帮忙发一下，你把分数给他就可以了。
看代码，兼容 IE,FIREFOX 。
