Remove javascript function override

Question

I have a java script function override that occurs when certain condition is met. How can I reset these functions to its original state if I don't need it anymore.

function setProductFields() {

  if (shouldShow == 'true') {

      selectField = function() {
        //override
      }
  } else {
     selectField() <--- //return to its original state
  }
}

I've override the selectField() successfully. But I dont need it if shouldShow is false so I want it to revert to original — stuckoverflow24

Save a reference to the old selectField in a variable, prior to changing it:

var oldSelectField = selectField;

// ... other code ...

function setProductFields() {
  if (shouldShow == 'true') {
      selectField = function() {
        //override
      }
  } else {
     selectField = oldSelectField;
  }
}

Thanks. But it is still calling the selectField() inside the setProductFIelds() I've added an alert there

Oops all good now. I made a mistake calling the backup inside the setProductFields()
