<body>

function txtWordChangeHandler(sender) {

var txtWord = document.getElementById("txtWord");

if (10 - sender.value.length < 0) {

txtWord.innerHTML = 0;

sender.value = sender.value.substring(0, 10);

}

else

{

txtWord.innerHTML = 10 - sender.value.length;

}

</script>

<div>

不能超过10个字，你还可以输入<span id="txtWord">10</span>个字<br />

<asp:TextBox ID="TextBox1" runat="server" Height="177px" TextMode="MultiLine"

Width="356px" onkeyup="txtWordChangeHandler(this)"></asp:TextBox>

</div>

<asp:Button ID="btnsubmit" runat="server" Text="提交" />

</form>

</body>

</html>

向AI问一下细节
