Javascript dropdown menu link
Posted on 2001-06-05
I am using the following javascript but I need to be able to have multiple dropdown lists on the same page.
<script language="JavaScript">
function pulldown_menu()
{
// Create a variable url to contain the value of the
// selected option from the the form named pulldown and variable selectname
var url = document.pulldown.selectna
// Re-direct the browser to the url value
window.location.href = url
}
</script>
<script language="JavaScript">
function pulldown_menu()
{
// Create a variable url to contain the value of the
// selected option from the the form named pulldown and variable selectname
var url = document.pulldown.selectna
// Re-direct the browser to the url value
window.location.href = url
}
</script>

Okay you have a form named pulldown and the select is named selectname
And I assume that you are triggering the function with the onchange event of the select.
with: onChange="pulldown_menu()"
All you have to do is elimnate the hard coded names with
onChange="pulldown_menu(th
And change the function to:
function pulldown_menu(EL)
{
var url = EL.options[EL.selectedInde
// Re-direct the browser to the url value
window.location.href = url
}
Then you can add additional selects in the same format the the present form, or add a new form with additional selects.

Two problems one minor and one major
name="selectname" -- you want to make that name unique to each select to avoid problems maintaining it.
onChange="pulldown_menu(4)
Shoud be onChange="pulldown_menu(th
This is a JavaScript operator that returns the current object so in this context it is the same as:
document.pulldown.selectna
which is why you want a unique name for each select. It then allows the function to be applied to any select where you call it.

That worked great. Thanks.
One more question. How can I direct the page that each dropdown goes to a specific frame target called "main"

Never mind. I figured this last part out.
I put in:
// Re-direct the browser to the url value
parenet.main.href = url
}
I put in:
// Re-direct the browser to the url value
parenet.main.href = url
}
Glad I could help. You help a lot in the process, because you respond back with a good description of how you are. Sometimes we have to ques and it make it tougher.
Thanks for the A. :^)

COBOLdinosaur,
One follow up question and I'll post it as a new question and give you points if you know the answer.
On the above Javascript is there a way to make it so that after a link is selected from one of the dropdown menus it refreshes the page so that all the dropdown menus go back to there original state, where the term "Select Option" is showing?
Thanks.
