<script type = text/javascript>

</script>

 

创建数组:

var myarr = new Array();

myarr[0] = 1;

myarr[1] = 2;

 

也可以:

var myarr = new Array(1,2);

 

还可以:

var myarr = [1,2];

 

语句，与java差不多:

if(myarr[0] ==1){} else{};    switch() case1:  break;   ||||||| 

for(); while();  do----while();   continue;

 

函数：

function add(){};

function add(x,y);
