Here you go:

arr.deleteElem = function ( val ) {
    for ( var i = 0; i < this.length; i++ ) {
        if ( this[i] === val ) {
            this.splice( i, 1 );
            return i;
        }
    }
};

The deleteElem method returns the index of the removed element.

var idx = arr.deleteElem( 'red' ); // idx is 1
