如果不是Javascript：则应为'）'

Question

im newbie in javascript. Can you guys help me on this Dolby script implementation? Getting error on Microsoft Edge: expected ')' after if statement.

         this.analyzer = new Analyzer({
            if( Dolby.checkDDPlus() === true ){
            url: 'http://example.com/samples_Dolby.mp4',
            } else {
            url: 'http://example.com/samples_Dolby.mp3',
            }
            onPlay: function() {
                button.classList.add('pause');
                button.classList.remove('play');
            },
            onPause: function() {
                button.classList.remove('pause');
                button.classList.add('play');
            },
            onEnd: function() {
                button.classList.remove('pause');
                button.classList.add('play');
            }
        });

Thank you

A ternary operator ?: would help.

    this.analyzer = new Analyzer({
        url: Dolby.checkDDPlus() ? 
            'http://example.com/samples_Dolby.mp4' :
            'http://example.com/samples_Dolby.mp3',
        // ...
    });
