页面刷新后Reset Button 不能清空form 的TextBox中的内容!

[yslhust]

初次进入页面在TextBox 中输入内容可用Reset Button 清空,当执行PostBack刷新页面后Reset Button 就不起作用了,哪位有遇到同样问题吗?

<INPUT id="Reset1" type="reset" value="Reset" name="Reset1" >
改为在服务器端运行也不起作用.后又加了 CausesValidation="False" 也不行.

reset button only set the controls to their default values, to clear them, try


client side:

<script language="javascript">
function ClearTextBox()
{
var inputs = document.all.tags("INPUT");
for(var i=0; i < inputs.length; i++)
if (inputs[i].type == "text")
inputs[i].value = "";

var inputs = document.all.tags("TEXTAREA");
for(var i=0; i < inputs.length; i++)
inputs[i].value = "";
}
</script>


server side:

void ClearTextBox(Control c)
{
if (c is TextBox)
((TextBox)c).Text = "";

foreach (Control cc in c.Controls)
ClearTextBox(cc);
}

ClearTextBox(Page);

也不行啊，思归大哥，到底这两个函数怎么放才行咧？

我的办法是:
<INPUT class="input1" type="button" value="取 消" onclick="window.location.href='url';">
但是需要当页刷新，有点麻烦的。

1. client side solution:

<script language="javascript">
function ClearTextBox()
{
var inputs = document.all.tags("INPUT");
for(var i=0; i < inputs.length; i++)
if (inputs[i].type == "text")
inputs[i].value = "";

var inputs = document.all.tags("TEXTAREA");
for(var i=0; i < inputs.length; i++)
inputs[i].value = "";
}
</script>


<input type="button" value="clear" onclick="javascript:ClearTextBox()">

or

2. server side solution:

<form runat="server">
...
<asp:Button id="btn" runat="server" Text="Clear" OnClick="ClearText" />
</form>

<script language="C#" runat="server">
void ClearTextBox(Control c)
{
if (c is TextBox)
((TextBox)c).Text = "";

foreach (Control cc in c.Controls)
ClearTextBox(cc);
}


void ClearText(Object sender, EventArgs e)
{
ClearTextBox(this);
}
</script>
