Hello all,

I am new to JavaScript..

I have a ‘year’ field and below that is a ‘month’ drop down box

I want the user to 1st enter the year and then pull the drop down menu. If they try to pull the dropdown menu before they enter the year I want an ‘alert’ to pop up and ask the user to enter the year first.

It will be of great help if you guys can give me some suggestions

Thanking you all in advance

regards,
smitha

<i>
</i>&lt;HTML&gt;
&lt;HEAD&gt;
&lt;script&gt;
function foo() {
if(document.getElementById('year').value=='') {
alert ('Please type the year first');
document.getElementById('year').focus();
}
}
&lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;

&lt;form name="form1"&gt;
&lt;input type="text" value='' name='year'&gt;
&lt;select name="aaa" onfocus="foo()" onchange="foo()"&gt;
&lt;option&gt;Select something&lt;/option&gt;
&lt;option&gt;a&lt;/option&gt;
&lt;option&gt;b&lt;/option&gt;
&lt;/select&gt;
&lt;/body&gt;
&lt;/html&gt;
