jQuery - use variable as function name

Question

In Jquery i\'d like to disable any plugin I want by changing a variable name. However the following code doesnt work

function disablePlugin(functionName) {
          


        

Answer 1

To invoke the function passed in as a string, you could do

function disablePlugin(functionName) {
    $('#divID')[functionName]('disable')
}

disablePlugin('sortable');

Answer 2

This is how you would do that:

function disablePlugin(functionName) {
  $('#divID')[functionName]('disable')
}

disablePlugin('sortable');

This works because someObject.foo is the same thing as someObject['foo']
