I really think that is your best approach. The time it takes JS to loop over an array is nothing compared to a page request to the server. Just make sure you jsstringformat() any values going into the array.

I think a good question to ask yourself is, do you really need to hit the database for this, or will you know all the possible options right up front. I don't know your exact application here, but I assume you have some sort of display value and identifier you want to save based on the selection in the drop down box. If possible, I would populate the drop down with a query which also contains the other values you would need for each row should it be chosen. (As long as that can be determined up front). Now, you can do a couple different things. You can build a JavaScript array when the page loads which stores the options. Onchange of the drop down go to that array index to find what values you need to copy into the text box and hidden fields. Also, I am not sure about other browsers, but IE will let you make up attributes to HTML tags and reference them as element.attribute_name For instance: <select name="test_select" id="test_select " onChange="do_something(this);"> <option value="val1" other_value_i_need_for_later="foo">me</option> <option value="val2" other_value_i_need_for_later="bar">you</option> </select> Now let's say you choose the second option in the drop down Function do_something(el) { var that_other_value_i_needed = el.options[el.selectedIndex]. other_value_i_need_for_later; document.getElementById('text_field_id').value = that_other_value_i_needed; } I don't know if this is anywhere close to what you want, but it is my two cents :) It sounds like there are probably lots of ways to do what you want, just remember-- why go back to the database, if you can get it to begin with. ~Brad I have a text field and a hidden field that I want to populate based on a dropdown. Here's the trick, once the value of the dropdown is passed, I want the Hidden field and the text field to be based on queried values. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:229106 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
