Filtering Large Select Lists


For best results, download the example HTML file and use it as a template.
  1. In the HEAD section of your HTML file, load the javascript code:
    <SCRIPT TYPE="text/javascript" SRC="filterlist.js"></SCRIPT> 
  2. In the body of your HTML file, set up your FORM and your SELECT list just like you normally would. Be sure to give both your FORM and your SELECT elements a NAME attribute:
    <FORM NAME="myform" ACTION="">
    <SELECT NAME="myselect">
     <OPTION>Keanu Reeves
     <OPTION>Laurence Fishburne
  3. After the SELECT list, initialize a filterlist object. Use the names that you gave your FORM and your SELECT list.
    <SCRIPT TYPE="text/javascript">
    var myfilter = new filterlist(document.myform.myselect);
  4. To filter the select list, use the set method:
    <A HREF="javascript:myfilter.set('keanu')">keanu</A>
    <A HREF="javascript:myfilter.set('fish.*')">fishburn</A>

    To reset the select list, use the reset method:

    <A HREF="javascript:myfilter.reset()">reset</A>

    To change the case-sensitive flag, use the set_ignore_case method:

    <A HREF="javascript:myfilter.set_ignore_case(false)">case-sensitive</A>
    <A HREF="javascript:myfilter.set_ignore_case(true)">ignore case</A>
