Question

I’ve a set of jquery and generally javascript function in a js. Now I want to avoid some of the functions to be available on some condition. For example:

function test () {
    alert("hi");
}

function avoid () {
   if(condition)  {
     //here avoid to call test
   }
}

Thanks

If you want to remove a function without errors (provided the caller of the function doesn’t expect a returned result), you might do

function avoid () {
   if(condition)  {
     test = function(){}; // does nothing
   }
}

Note that if your avoid function is in a different scope, you might have to adapt. For example if test is defined in the global scope, then you’d do window.test = function(){};
