CodeIgniter + ExtJS 2.2 ? Tutorial?

[eluser]Fielder[/eluser]
Mirage, do you know how to pass a parameter into the extjs js script from the CI controller?

For instance, I'm loading a grid using

Code:

var dataProxy = new Ext.data.HttpProxy({
        url: '../../index.php/reports/listMultistores/' + conid + '/',
        method: 'POST'
    });

but I need to be able to specify the 3rd segment of the URI to run a specific database query.

Any ideas?

I was putting

Code:

Ext.onReady(function() {

    var conid = "<?= $ext_id; ?>;"
    .
    .
    .
    var dataProxy = new Ext.data.HttpProxy({
        url: '../../index.php/reports/listMultistores/' + conid + '/',
        method: 'POST'
    .
    .
    .
    });

in my js file but it's not interpreting the $ext_id param.
