how could I write the following Code that it is supported in all browsers? Because it seems that the forEach-Function is not supported in IE8...

    digits.forEach( function( value, index ) {
    // create a span with initial conditions
    var span = $( '<span>', {
        'class': 'digit0',
        'data': {
            'current': 0,
            'goal' : value
        }
    } );
    // append span to the div#number
    span.appendTo( $( 'div#number' ) );
    // call countUp after interval multiplied by the index of this span
    setTimeout( function() { countUp.call( span ); }, index * interval );
} );

See the full Code here: / (it´s not working with all browsers) Thanks in advance.

• Internet Explorer doesn't support "for each" loops. You will need to change the code to use regular for loops: – Rinku Commented Feb 12, 2013 at 7:20
• You can use pure javascript for loop for this, and jQuery are ending support of old browsers like IE8 – Taron Mehrabyan Commented Feb 12, 2013 at 7:21
• 4 Since you already use jQuery, use $.each(). – JJJ Commented Feb 12, 2013 at 7:21

The MDN documentation for forEach includes two implementations of the method for use in browsers that implement earlier versions of JS.

I'll reproduce the quick one (see the link for the plete one) here:

if ( !Array.prototype.forEach ) {
  Array.prototype.forEach = function(fn, scope) {
    for(var i = 0, len = this.length; i < len; ++i) {
      fn.call(scope, this[i], i, this);
    }
  }
}
