之后我们就要模拟一个点击事件了

    // 背景音乐的

    var audio = document.getElementById('bgMusic');
    var dianMusic =document.getElementById('dianMusic');
    var iconMusic = document.getElementsByClassName('icon-music')[0];
    var iconForbidMusic = document.getElementsByClassName('icon-forbidMusic')[0];
    function audioAutoPlay(audio) {
        document.addEventListener("WeixinJSBridgeReady", function () {
            audio.play();
        }, true);
        document.addEventListener('YixinJSBridgeReady', function () {
            audio.play();
        }, false);
    }
    audioAutoPlay(audio);

这样就ok了
