Uncaught TypeError: Illegal invocation in javascript


The console's log function expects this to refer to the console (internally). Consider this code which replicates your problem:

var x = {};x.func = function(){    if(this !== x){        throw new TypeError('Illegal invocation');    }    console.log('Hi!');};// Works!x.func();var y = x.func;// Throws errory();

Here is a (silly) example that will work, since it binds this to console in your make function:

var make = function(callback,params){    callback.call(console, params);}make(console.log,'it will be accepted!');

This will also work

var make = function(callback,params){    callback(params);}make(console.log.bind(console),'it will be accepted!');


You can wrap the function which need 'this' to a new lambda function, and then use it for your callback function.

function make(callback, params) {  callback(params);}make(function(str){ console.log(str); }, 'it will be accepted!');
