Class Ext.form.Action

Failure type returned when client side validation of the Form fails thus aborting a submit action. Client side validation is performed unless clientValidation is explicitly set to false.

Failure type returned when a communication error happens when attempting to send a request to the remote server. The response may be examined to provide further information.

Failure type returned when the response's success property is set to false, or no field values are returned in the response's data property.

Failure type returned when server side processing fails and the result's success property is set to false.

In the case of a form submission, field-specific error messages may be returned in the result's errors property.

The type of failure detected will be one of these: CLIENT_INVALID, SERVER_INVALID, CONNECT_FAILURE, or LOAD_FAILURE. Usage:

var fp = new Ext.form.FormPanel({
...
buttons: [{
    text: 'Save',
    formBind: true,
    handler: function(){
        if(fp.getForm().isValid()){
            fp.getForm().submit({
                url: 'form-submit.php',
                waitMsg: 'Submitting your data...',
                success: function(form, action){
                    // server responded with success = true

                    var result = action.result;
                },
                failure: function(form, action){
                    if (action.failureType === Ext.form.Action.CONNECT_FAILURE) {
                        Ext.Msg.alert('Error',
                            'Status:'+action.response.status+': '+
                            action.response.statusText);
                    }
                    if (action.failureType === Ext.form.Action.SERVER_INVALID){
                        // server responded with success = false

                        Ext.Msg.alert('Invalid', action.result.errormsg);
                    }
                }
            });
        }
    }
},{
    text: 'Reset',
    handler: function(){
        fp.getForm().reset();
    }
}]
