Question

我有java脚本代码来设置ajax控件的一些属性。

代码工作正常如果我把它放在asp.net页面但是当我使用内容页面并且在部分代码中发布代码时将无法正常工作，这会改变ajax控件属性的值。

我的页面有文本框，复选框，MaskedEditExtender和MaskedEditValidator。当用户选中该框时，掩码属性和其他一些属性应该改变。

代码正常但内容页面没有。

这是我在asp.net页面的代码：

Answer 1

如果在内容页面中使用任何Extender，$ find方法的参数应该访问Extender的BehaviorID。

将BehaviorID属性添加到MaskedEditExtender：

       <ajaxToolkit:MaskedEditExtender ID="MaskedEditExtender6" BehaviorID="MaskedEditExtender6" runat="server" Mask="999" 
            DisplayMoney="None" MaskType="number" TargetControlID="TextBox4" ClearMaskOnLostFocus="true" 
            InputDirection="RightToLeft" AutoComplete="False"> 
        </ajaxToolkit:MaskedEditExtender>

Answer 2

要更改MAskEditExtender的掩码值，必须使用

$find('ID of element').set_Mask("new value of mask");
$find('ID of element')._convertMask();

或

$find('ID of element')._MaskConv = "new value for mask";

javascript无法使用asp.net内容页面
