Remote Scripting with Javascript, IFrames and PHP Page 5

This code also includes a Javascript function called “buildQueryString” to,
obviously, build a query string, but since I only needed to pass a single
search term I omitted that function, and changed this line:

var URL = ‘server.html’ + buildQueryString(theFormName);

…to this line:

var URL = ‘./server.php?s=’+term;

I also added the “term” parameter to the callToServer() function.

Now, each time a user makes a keystroke in the “nameSearch” textbox, the
doSearch() Javascript function is called. That function looks like this:

<?php
function doSearch(theForm) 
{
    var searchTerm = theForm.elements['nameSearch'].value;
    if(searchTerm.length < 2) 
    {
        return;
    }
    var s="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ -.";
    if(s.indexOf(searchTerm.charAt(searchTerm.length-1)) == -1) 
    {
        return;
    }
    callToServer(searchTerm);  
}
?>
