Asp.NET控制輸入數字和字母的函數
通過對輸入的數字和字母進行控制判斷，通過JavaScript的函數進行距離說明，
首先再aspx中增加二個label和對應的textbox空間
然後再<head></head>中輸入
<script language="javascript" type="text/javascript">
function judgeNumber(code)
{
if(code>=48 & code<=57)
{
return true;
}
else
{
return false;
}
}
function judgeChar(code)
{
if((code>=65 & code<=90)||(code>=97 & code<=122))
{
return true;
}
else
{
return false;
}
}
</script>
對應的textbox的onkeypress的事件如下：
<div>
數字：<asp:TextBox ID="TextBox4" runat="server" onkeypress="return judgeNumber(event.keyCode);"></asp:TextBox>
字母：<asp:TextBox ID="TextBox5" runat="server" onkeypress="return judgeChar(event.keyCode);"></asp:TextBox>
</div>
