How to pass custom argument via submit callback function in ExtJS

This is my callback function with custom parameter.

function successCallback(form, action, customParam){
    if(customParam == '1'){
        // do xxx
    }
    else if(customParam == '2'){
        // do yyy
    }
    else {开发者_运维技巧
        // do zzz
    }
}

Do you have any idea to pass custom value via ExtJS submit configuration ?

myForm.getForm().submit({
    url: 'http://mysite.com/target',
    method: 'POST',
    success: successCallback(9), // ??
});

Thank you.

For your case, just use this:

...
success : successCallback
...

The successCallback function will be called with all those parameters.

In future, use createDelegate for callback functions with parameters and scope.

...
success : function(){
    successCallback.createDelegate(param1, param2)();
}
...

in particular:

  ...
  success: function() { successCallback(1,2,3); } ,
