Javascript to Populate ASP Form Fields based on Dropdown Selection

in select box write Onchange event to call javascript function and in js function find the equivalent age and grade value from array based on selected name field value
Note your array should be accessible from jS

see this example

You description is accurate but I don't see that the example shows what I need.

I am looking for a code example of how to create a javascript array after doing a SQL select.  The onchange on the dropdown would populate text boxes from the array, not another dropdown box.  If your example could be modified to show that solution maybe it will work but as I mention I am new to JavaScript.

Thanks

Example for creating JS array from sql query

http://aspdotnetcodebook.blogspot.in/2008/03/how-to-fill-javascript-array-from.html

use indexOf function to find the equivalent value in age array and grade array
and fill values using

document.getElementById(age).value='equivalent value from array'

I am using Classic ASP not ASP.NET.  I should have been more clear about that.

Thanks

I'm glad you figured it out.  Just remember the client side code (javascript) loads on the page last.  Your asp/vb code gets processed before the page loads, then html and js gets written to the page and finally the js code gets processed.

With this in mind, if you want to end up with generated code like below

<script>
var mycars = new Array();
mycars[0] = "Saab";
mycars[1] = "Volvo";
mycars[2] = "BMW";
</script>

but the data is in your database, you can generate it with your serverside code like

jsCode="<script>"
jsCode=jsCode&"var mycars = new Array();"
jsCode=jsCode&"mycars[0] = ""Saab"";"
jsCode=jsCode&"mycars[1] = ""Volvo"";"
jsCode=jsCode&"mycars[2] = ""BMW"";"
jsCode=jsCode&"</script>"
response.write jsCode
