Hi


你必须使用形式JavaScript。

要通过JavaScript隐藏元素，您可以使用以下代码：

Hi
You must use form JavaScript.
For hide a element by JavaScript you can use from bellow code:

<script type="text/javascript">
    function YourFunctionName() {
        document.getElementById('YourTextBoxID').style.visibility = 'hidden';
        return true;
    }
</script>

对于showa元素的JavaScript，您可以使用以下代码：

For showa element by JavaScript you can use from bellow code:

<script type="text/javascript">
    function YourFunctionName() {
        document.getElementById('YourTextBoxID').style.visibility = 'visible';
        return true;
    }
</script>

如需拨打此功能，您可以使用以下代码：

For call this function you can use from bellow code:

Radio1<input type="radio" id="TestRadio1" name="RadioName1" value="RadioButton1"  önclick="return YourFunctionName();" />
