我的任务
分享关于一个函数同时验证多个表单问题！
我有一个页面里，有多个FORM的TEXT框需要判断是否为数字，现在我知道怎么判断数字，但我做提交时出错了，我写出来吧
<script language="javascript">
function checkNum(str){
if(!/\D/.test(str))
form.submit(); //此句出错，因为必须指定一个具体的FORM名称，而我需要在不同时候提交不同的FORM，怎么办？
else
alert("请输入数字!");
}
</script>
<script language="javascript">
function checkNum(str){
if(!/\D/.test(str))
form.submit(); //此句出错，因为必须指定一个具体的FORM名称，而我需要在不同时候提交不同的FORM，怎么办？
else
alert("请输入数字!");
}
</script>

xuzuning(唠叨) 的方法，第一个添数字可以提交，但再在第二个框里添数字就会出现脚本错误！
请问那位高手可以解决啊！！！
