javascript - ACF Google map - 更改样式？

Question

我已经启动并运行了 WordPress 网站，并使用 ACF 插件创建了 Google map 字段。这一切都很棒，但我想更改默认的谷歌地图样式。我的站点地图需要一些更浅的灰度样式。我使用了 ACF 文档中的下面的代码，正如我所说，它工作得很好，但是当我尝试更改任何样式时，什么也没有发生。我必须指出，我不懂 javascript/jquery，所以请考虑到这一点。我确实浏览了整个谷歌地图 API 文档，但我就是无法做到其中任何一个。我尝试了很多东西，要么什么也没发生，要么我把谷歌地图搞砸了。那么有人可以给我指出正确的方向，或者给我一个示例代码并解释在哪里使用它。我是否应该删除部分现有代码，或者只是添加额外的代码和平等？预先感谢，祝一切顺利!

有很多样式选项您可以通过此尝试 google map documentation

我对样式选项做了一些更改，您可以尝试自己的颜色。

var args = {
    zoom: 15,
    center: new google.maps.LatLng(0, 0),
    mapTypeControl: false,
    panControl: false,
    scrollwheel: true,
    zoomControlOptions: {
        style: google.maps.ZoomControlStyle.SMALL,
        position: google.maps.ControlPosition.RIGHT_CENTER
    },
    styles: [{"featureType":"water","elementType":"all","stylers":[{"hue":"#e9ebed"},{"saturation":-78},{"lightness":67},{"visibility":"simplified"}]},{"featureType":"landscape","elementType":"all","stylers":[{"hue":"#ffffff"},{"saturation":-100},{"lightness":100},{"visibility":"simplified"}]},{"featureType":"road","elementType":"geometry","stylers":[{"hue":"#bbc0c4"},{"saturation":-93},{"lightness":31},{"visibility":"simplified"}]},{"featureType":"poi","elementType":"all","stylers":[{"hue":"#ffffff"},{"saturation":-100},{"lightness":100},{"visibility":"off"}]},{"featureType":"road.local","elementType":"geometry","stylers":[{"hue":"#e9ebed"},{"saturation":-90},{"lightness":-8},{"visibility":"simplified"}]},{"featureType":"transit","elementType":"all","stylers":[{"hue":"#e9ebed"},{"saturation":10},{"lightness":69},{"visibility":"on"}]},{"featureType":"administrative.locality","elementType":"all","stylers":[{"hue":"#2c2e33"},{"saturation":7},{"lightness":19},{"visibility":"on"}]},{"featureType":"road","elementType":"labels","stylers":[{"hue":"#bbc0c4"},{"saturation":-93},{"lightness":31},{"visibility":"on"}]},{"featureType":"road.arterial","elementType":"labels","stylers":[{"hue":"#bbc0c4"},{"saturation":-93},{"lightness":-2},{"visibility":"simplified"}]}]
};

使用此代码之前，请更新中心选项中的纬度和经度选项。
