Call a function specified in variable in javascript

Question

I have a input hidden type which specifies the function that needs to be called. How can I do it using Javascript/Jquery

<input type="hidden" name="extrafunction" id="extrafunction" value="edit_data_provider/DataProviderChange1" />

and in Javascript file

        var fullfunctionName = $('#extrafunction').val();
        var control_name    = fullfunctionName.split('/')[0];
        var function_name   = fullfunctionName.split('/')[1];
        if(control_name == client_control_name)
        {
            //The function call which is in function_name var should come here

        }

Answer 1

You can use :

window[functionName](arguments);

Hope this helps.
