方法:
var character = new Array("A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","X","Y","Z")
for(var i=0i<25i++)
{
alert(character[i])
}
可以。
是要只能输入数字?那就这个:onkeyup="value=value.replace(/[^\d]/g,'') "onbeforepaste= "clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"
