Alter form data using the beforesubmit event

[semiaddict]

According to the documentation of the event beforesubmit in Ext.form.Panel , I should be able to modify the values submitted, but I can't figure out how.

Implementations may adjust submitted form values or options prior to execution.

I've tried modifying the variable values, but this has no effect.

Any help is highly appreciated.

Note: I'm basically trying to send a JSON string, so I need to encode the values using JSON.stringify.

This looks like a bug. Thanks for the report.

This is working for me, using the following block of code:

var form = Ext.Viewport.add({
    xtype: 'formpanel',
    items: [
        {
            xtype: 'textfield',
            label: 'one',
            name: 'name',
            value: 'go'
        },
        {
            docked: 'bottom',
            xtype: 'toolbar',
            items: [
                {
                    xtype: 'button',
                    text: 'submit',
                    handler: function() {
                        form.submit({
                            method: 'POST',
                            url: 'test'
                        });
                    }
                }
            ]
        }
    ],
    listeners: {
        beforesubmit: function(form, values, options) {
            values.test = "hello";
        }
    }
});

This will post: 'name=go&test=hello'

This does not seem to work in ST 2.3.1!

Any updates about this?

I'm trying to add/change/format the values of the submit just like rdougan said, but is not working.

Please help!

I'm running into the same issue. The server expects a timestamp, but the form is sending something like:
Tue Jan 01 1980 00:00:00 GMT+0100 (CET)

I'm trying:

onBeforeSubmit: function (form, values, opts, evt, eOpts) {
    var timestamp = Ext.Date.format(values.dateOfBirth, 'U');
    values.dateOfBirth = window.parseInt(timestamp, 10);
} 

to no avail. Using ST 2.3.1
Is there a workaround/override?
