Console undefined issue in IE8 [duplicate]

Answer 1

Just check if the console exists

window.console && console.log('foo');

Answer 2

You need to check what the type of console is, and also what the type of console.log is. You might want to check this link:

Answer 4

Try using a condition like this instead, as if console is not supported it will throw undefined not false;

if(typeof console !== "undefined") {
console.log('removing child');
}

However to prevent having to wrap all your console log statemnts I would just put this snippet in your code. This will stop IE throwing any error

if(typeof console === "undefined") {
    console = {
        log: function() { },
        debug: function() { },
        ...
    };
}

Answer 5

You could set console.log to an empty function

if(typeof console === "undefined") {
    console = {
        log : function () {}
    }
}

This way you have to bother only once.l

Answer 6

You could add the following to the if clause:

if (console && console.log) {
    console.log('removing child');
}

Or write a log wrapper around the console.log function like this.

window.log = function () {
    if (this.console && this.console.log) {
        this.console.log(Array.prototype.slice.call(arguments));
    }
}

Use it like this:

log("This method is bulletproof", window, arguments");
