Answer 2

 没仔细看，是这个吗？
       resize: function() {            this.wh = this.oc.clientWidth;
            this.ht = this.oc.clientHeight;
            //                this.ws = this.scrollbar.offsetWidth;
            this.calc();
            this.run(true);
        },

Answer 3

你的图片什么情况下变大变小？可能是这段
/* ==== right arrow右滚动按钮事件 ==== */ 
        this.arR.onclick = this.arR.ondblclick = function() { 
            if (this.parent.view < this.parent.NF - 1) 
                this.parent.calc(1); 
        } 
        /* ==== Left arrow左滚动按钮事件 ==== */ 
        this.arL.onclick = this.arL.ondblclick = function() { 
            if (this.parent.view > 0) 
                this.parent.calc(-1); 
            //                if(this.parent.view <= 0) 
            //                    this.parent.calc(5); 
        } 

Answer 4

    if (Math.abs(sx) > 2 || Math.abs(sw) > 2 || res) { 
                    /* ---- paint only when moving ---- */ 
                    this.x0 += sx * .1; 
                    this.w0 += sw * .1; 
搞定了！原来是这段！！！！！
