这应该算简单的算法题，我没深入学习过算法，所以只有用第一反应得到的方法来解答啦
思路：写一个判断数字是否是素数的函数，然后在循环中调用它，将所得的结果push到数组中，解法如下：

var prime=[];

for(var i=0;i<10000;i++){
	isPrime(i)?prime.push(i):null;
}

function isPrime(num){

这道题有两种思路：
1.第一种是获得所有的LI元素，然后从中取出含有test类的元素设置背景为黄色：
//通用做法
var liArray=document.getElementsByTagName("li");
for(var i=0,l=liArray.length;i<l;i++){
	var pattern=/\btest\b/,
		self=liArray[i];
	//考正则的话考点就在这里，考察对正则的几个常用方法的掌握，还可以使用：
	//liArray[i].className.search!=-1?self.style.background="yellow":null;
	//pattern.test(liArray[i].className)?self.style.background="yellow":null;
