在上面的下拉列表中，我想要隐藏科罗拉多州＆＃39;下拉选项如果满足下面提到的功能条件（参见下面的功能）：
// Below is the function and condtion :
<Function name="Hidedropdown">
<Code>
<![CDATA[
function Hidedropdown()
{
var formObj = [*form*];
var city1 = formObj.F("City").getValue();
alert(formObj.F("City").getValue());
if (city1 == "SWC")
{
formObj.F("StatePDF").show();
}
else
{
formObj.F("StatePDF").hide();
}
alert(formObj.F("City").getValue());
}
]]>
</Code>
</Function>
如果City1 ==＆＃34; SWC＆＃34;然后＆＃39;科罗拉多＆＃39;应显示上面下拉列表中的选项 它应该被隐藏。
我想隐藏并仅使用javascript而不是jquery显示colorado选项。 请告诉我简单的方法因为我已经尝试过使用动态下拉菜单 但它在我们的项目中并不支持。
Please help me. Thanks in advance.
