<script type="text/javascript">
window.onload = function () {
var myp = document.getElementById("myp");
var contentArr = "秋天来临了天空像一块覆盖大地的蓝宝石。村外那个小池塘睁着碧澄澄的眼睛，凝望着这美好的天色。一对小白鹅侧着脑袋欣赏自己映在水里的影子。山谷里枫树的叶子，不知是否喝了过量的酒，红的像一团火似的。村前村后的稻子，低着头弯着腰，在秋风中默默地等待着人们去收割，半空中，排着“人”字形的雁群，高兴的唱着歌，告别人们，向天边慢慢飞去……".split("");
var content = "";
var index = 0;
var ID = setInterval(function () {
content += contentArr[index];
myp.innerHTML = content + "_";
index++;
if(index === contentArr.length){
myp.innerHTML = content ;
clearInterval(ID);
console.log("结束了");
}
