listbox selection to autopopulate fields?

[Dave]

Hi folks,

I'm in the middle of adding some validation functionality to an inventory
tracking form.

What I would like to do is have one dropdown menu/Listbox(Part Number) and
another text field (Product Description).

When the user selects an item from the drop down (IE 12S0FB) it will
autopopulate the text field with a description of the product. At the
moment I will hard code the values in. Can anyone help me out here?

Thanks,
Dave

Let's say you've created an array of description strings named descs, your
form is called form1 and it contains a textarea named descText.

<select onchange="docum ent.form1.descT ext.value=descs[this.selectedIn dex]">

Use an object (not an array) to map part numbers to descriptions:

var p_desc = {
'IE 12S0FB' : 'Giant Veeblefetzer' ,
'IE 76S0GB' : 'Tiny Veeblefetzer' ,
.........
'IE 22340x' : 'Blue Klarn'
}

Then...

<select...oncha nge="product_de scription.value =(p_desc[this.options[this.selectedIn dex].value]||'')">
<option value="">choose </option>
<option value="IE 12S0FB">IE 12S0FB</option>
.........
</select>
<textarea name="product_d escription"></textarea>
