Post Raw Json via .submit()

Question

How can I post username/password as Raw JSON via form.submit().

loginForm.submit({  
    url: 'localhost/login',
    method: 'post',
    jsonData: loginForm.getValues()
...
    success: ...

even with Ext.JSON.encode(loginForm.getValues()) server is receiving as username=test&password=test which I need to be {"username":"test","password":"test"}

You should probably try something like

Ext.Ajax.request({
    method: 'POST',
    url: 'submit.php',
    params  : {
        data: Ext.encode(loginForm.getValues())
    },
    success: function() {
    },
    failure: function() {
    }
});
