Submit a form and get a JSON response with jQuery

this one helps. If you want to get the response in a callback, you can't post the form. Posting the form means that the response is loaded as a page. You have to get the form data from the fields in the form and make an AJAX request.
    $.post($(this).attr('action'), $(this).serialize(), function(json) {
    }, 'json');
    return false;

extjs - How to submit a form when the response is not json?

I hope this helps . Finally, it was impossible for me to get to work the form.submit() of ExtJs. I needed an implementation using Ext. And since this is a frequent pattern in my application, it is important to have a short an simple solution.
This is what I finally found (I have a modal window containing the form):
var values = me.up('form').getValues(),
panel = Ext.create('My.view.MyPanel', {
    xtype: 'panel',
    loader: {
        url: Paths.ajax + 'sav_vpc/douane.php',
        method: 'get',
        params: values,
        autoLoad: true
