## scrollTo scrollBy
```html
#c {
	width:100px;
	height:50px;
	background:#eaf;
	position:fixed;
	right:0px;
	top:100px;
}
<div style="width:200px;margin:0 auto;height:auto;background:-moz-linear-gradient( top,#add,#eef); ">
    除了您已经在线性渐变中看到的起始位置，方向，和颜色，径向梯度允许你指定渐变的形状........我们主要通过不同的示例来对比CSS3径向渐变的具体用法
</div>
<div id="c">点击滚动</div>
<script type="text/javascript">
// 滚动到指定的位置  x  y
window.scrollTo(200, 400);

//按照指定的步进来滚动
c.onclick = function() {
    window.scrollBy(10,10);
    //启动定时器
    setInterval(function(){
    	window.scrollBy(0,1);
    }, 30);
}
</script>
```

### 事件1: onresize

<script type="text/javascript">
    window.onresize = function(){
        console.log('222');

</body>
<script type="text/javascript">
    var div = document.getElementTagName('div')[0];
    window.onscroll = function(){
        // 获取当前窗口的滚动距离 
        var sT = document.documentElement.scrollTop;

  Nam liber tempor cum soluta nobis eleifend option congue nihil imperdiet doming id quod mazim placerat facer possim assum. Typi non habent claritatem insitam; est usus legentis in iis qui facit eorum claritatem. Investigationes demonstraverunt lectores legere me lius quod ii legunt saepius. Claritas est etiam processus dynamicus, qui sequitur mutationem consuetudium lectorum. Mirum est notare quam littera gothica, quam nunc putamus parum claram, anteposuerit litterarum formas humanitatis per seacula quarta decima et quinta decima. Eodem modo typi, qui nunc nobis videntur parum clari, fiant sollemnes in futurum.
