推荐答案
尝试使用此代码:
try use this code:
<script language="javascript" type="text/javascript">
function Radio1_onclick() {
document.getElementById('<%= TextBox1.ClientID %>').disabled = false;
}
function Radio2_onclick() {
document.getElementById('<%= TextBox2.ClientID %>').disabled = false;
}
function Radio3_onclick() {
document.getElementById('<%= TextBox1.ClientID %>').disabled = false;
document.getElementById('<%= TextBox2.ClientID %>').disabled = false;
}
</script>
或此代码:
or this code:
<script language="javascript" type="text/javascript">
function Radio_onclick() {
if(document.getElementById('Radio1').checked){
document.getElementById('<%= TextBox1.ClientID %>').disabled = false;
}
else if(document.getElementById('Radio2').checked){
document.getElementById('<%= TextBox2.ClientID %>').disabled = false;
}
else if(document.getElementById('Radio3').checked){
document.getElementById('<%= TextBox1.ClientID %>').disabled = false;
document.getElementById('<%= TextBox2.ClientID %>').disabled = false;
}
</script>
调用Radio_onclick函数的所有单选按钮onclick事件.
call Radio_onclick function all radio button onclick event.
我想您有第三个文本框为"TextBox3"，并且如果选中了任何单选按钮，则希望启用所有三个文本框.
编写一个常见的Javascript函数"EnableTextboxes()"，并在单选按钮的onClick事件上调用它.
I guess you have Third text box as "TextBox3" and you want to enable all three textboxes if any radio button is checked.
Write one common Javascript function "EnableTextboxes()" and call it on onClick event of your Radio Buttons.
function EnableTextboxes()
{
if(document.getElementById(''<%= Radio1 %>'').checked || document.getElementById(''<%= Radio2 %>'').checked ||
document.getElementById(''<%= Radio3 %>'').checked)
{
document.getElementById(''<%= TextBox1.ClientID %>'').disabled = false;
document.getElementById(''<%= TextBox2.ClientID %>'').disabled = false;
document.getElementById(''<%= TextBox3.ClientID %>'').disabled = false;
|
}
<input id="Radio1" type="radio" value="rd1" name="val" önclick="return EnableTextboxes()" />
<input id="Radio2" type="radio" value="rd2" name="val" önclick="return EnableTextboxes()" />
<input id="Radio3" type="radio" value="rd3" name="val" önclick="return EnableTextboxes()" />
