setting the input text w/ AJAX

[shaunwo]

I'm an AJAX / DOM Novice (at best) and trying to figure out how to write the value to a couple input fields. I don't remember exactly where I got the ajax.js file I'm using from (went to the website that I see in the comments, but no luck there), but what I already have works GREAT to populate the options in a select box. Now I'm trying to take that same code and get it to write the value to a couple input boxes.

Here's a link to my ajax javascript file:
http://www.leadingedgeroofing.com/manage/j/ajax.js

On the file that IS WORKING (get_material_containers.php) and writing the option tags, my code looks like this:

$container_r = @mysql_query($container_q) OR die ($container_q.'<br /><br />'.mysql_error());
if (mysql_num_rows($container_r) > 0) {
    echo 'obj.options[obj.options.length] = new Option(\' - select - \',\'\');'."\n";
    while ($container = mysql_fetch_array($container_r)) {
        echo 'obj.options[obj.options.length] = new Option(\''.addslashes(htmlentities($container['material_container'])).'\');'."\n";
    }
} else {
    echo 'obj.options[obj.options.length] = new Option(\' - select - \',\'\');'."\n";
}
 

And then here's what's NOT working to try and write to the text fields, from the get_manufacturer_warranty.php file:

if (mysql_num_rows($warranty_r) > 0) {
    echo 'obj.input = \''.mysql_result($warranty_r,0,'manf_warranty_cost').'\'; // set the value for the hidden input box
obj2.input = \''.mysql_result($warranty_r,0,'manf_warranty_cost').'\'; // set the value for the disabled input box';
}
 

And lastly, here's the code I have to call each file:

var ajax = new Array();
 
function getContainerList(materialSel,materialType,containerSel) {
    var material = materialSel.options[materialSel.selectedIndex].value;
    document.getElementById(containerSel).options.length = 0; // Empty the select box
    if(material.length>0){
        var index = ajax.length;
        ajax[index] = new sack();
 
        ajax[index].requestFile = 'http://www.leadingedgeroofing.com/manage/inc/get_material_containers.php?material_type='+materialType+'&manf_id='+material;    // Specifying which file to get
        ajax[index].onCompletion = function(){ createContainers(index,containerSel) };    // Specify function that will be executed after file has been found
        ajax[index].runAJAX();        // Execute AJAX function
    }
}
 
function createContainers(index,containerSel) {
    var obj = document.getElementById(containerSel);
    eval(ajax[index].response);    // Executing the response from Ajax as Javascript code    
}
 
function getWarrantyCost(materialSel,warrantyCost) {
    var material = materialSel.options[materialSel.selectedIndex].value;
    document.getElementById(warrantyCost).value = ''; // Empty the hidden input box
    document.getElementById(warrantyCost + '-disabled').value = ''; // Empty the 'disabled' input box
    if(material.length>0){
        var index = ajax.length;
        ajax[index] = new sack();
 
        ajax[index].requestFile = 'http://www.leadingedgeroofing.com/manage/inc/get_manufacterer_warranty.php?manf_id='+material;    // Specifying which file to get
        ajax[index].onCompletion = function(){ createWarrantyCost(index,warrantyCost) };    // Specify function that will be executed after file has been found
        ajax[index].runAJAX();        // Execute AJAX function
    }
}
 
function createWarrantyCost(index,warrantyCost) {
    var obj = document.getElementById(warrantyCost);
    var obj2 = document.getElementById(warrantyCost + '-disabled');
    eval(ajax[index].response); // Executing the response from Ajax as Javascript code
}
 

I'm hoping someone who's more familiar w/ DOM and AJAX will be able to see what I'm doing wrong fairly easily and be able to give me some pointers.

And then here's what's NOT working to try and write to the text fields, from the get_manufacturer_warranty.php file:

if (mysql_num_rows($warranty_r) > 0) {
    echo 'obj.input = \''.mysql_result($warranty_r,0,'manf_warranty_cost').'\'; // set the value for the hidden input box
obj2.input = \''.mysql_result($warranty_r,0,'manf_warranty_cost').'\'; // set the value for the disabled input box';
}
 

'obj.input' should be 'obj.value'.
