Use a variable that represents a web address in OnChange?

[ryanc]

I have a form that has a SELECT object. I would like to go to a URL dependent on the choice the user makes.

Something like this:

<select size="1" name="D1" onchange="window.location='http://localhost/test.htm?Choice=this.value'">
<option value="red">red</option>
<option value="blue">blue</option>
</select>

What I would like to see is "http://localhost/test.htm?Choice=blue" sent to the browser.
My syntax is wrong, or something. Can someone help me?

Hi ryanc,

Have to run off to eat.

<select....onChange='doSel(this)'>

function doSel(selObj)
{
for (i=0; i< selObj.length; i++)
if (selObj.options[i].selected)
location.href='http://localhost/test.htm?choice=' + selObj.options[i].value;
}


See the 'Select & Go Menus' script/tutorial at my site for an explanation fo the doSel() function.

I ran a few test and with using your code I developed this, and it works.

<select size="1" name="D1" onchange="window.location=document.all.D1.value">
<option value="http://www.go.com">Go</option>
<option value="http://www.sitepoint.com">SitePoint</option>
</select>

Gentlemen,

Within your responses you have demonstrated the exact reason I prefer this forum to the News Groups. When asking a question in the News Groups, the answer is usually a few lines, but the people responding would rather go into a 10 page thesis as to why the person asking the question should have referred to the perldocs, FAQs, etc. The whole purpose of using a forum is to tap the exact people who know the answer to your question.

Both your solutions were exactly what I was looking for.

Thank you.

Hi ryanc,

You're welcome.
But...
You shouldn't be too hard on the newsgroup people (I spend time there occasionally After all, what they say about checking the faqs and searching are things everyone should attempt first. In forums, a lot of responses are of the "search the forum" and 'follow this link' type. I use those myself once I have enough responses on the forum.
Other good sources (for javascript newbies) are:
1) http://htmlgoodies.earthweb.com --> the javascript primer
2) a decent, but easy to understand, book --> SAM's Javascript in 24 hours.
