function watch_ini(){ // 初始
for(var i=0; i<arguments.length; i++){
var oOption=new Option(arguments[i],arguments[i]);

}
}
function watch_add(f){ // 增加
var oOption=new Option(f.word.value,f.word.value);

用一个字符串创建一个数组方法:
复制代码 代码如下:
<script language="javascript">
</body>
</html>
<script>
functionspli(){
datastr="2,2,3,5,6,6";
varstr=newArray();
str=datastr.split(",");
for(i=0;i<str.length ;i++ ) {
document.write(str[i]+"<br/>");
} } spli();
</script>
