How to create an autocomplete select box by nmath
Posted: 5 Feb 04 (Edited 23 Apr 04)

I wanted to create a text box that allowed a user to start typing a word and if it was in the select box it would auto-complete.  This is the code that I used to solve the problem.  There is a text box that as the user inputs characters it searches the select box for matches, also if the user selects a value from the select box the text box is auto filled.


<script language="javascript">
function fillin()
var mytext = Mainform.mytext.value;
sellength = Mainform.wholetext.length;
var i;

for(i = 0; i<sellength; i++)
   if (Mainform.wholetext.options[i].text.toLowerCase().indexOf(mytext.toLowerCase(),0) == 0)
     {Mainform.wholetext.options[i].selected = true;


function filltext()
var selectedItem = Mainform.wholetext.selectedIndex;
var selectedText = Mainform.wholetext.options[selectedItem].text;

Mainform.mytext.value = selectedText;

Here is the HTML section:
<form name = "Mainform">
<input type = "text" name = &quot;mytext&quot; onkeyup = "fillin()">

<select name = "wholetext" onclick = "filltext()">
 <option>Red Flowers</option>
