javascript - 有没有办法从 javascript 中调用 Gmaps4rails.geocode(address) ？

Question

我想在javascript中做这样的事情：

var latLngMatches = Gmaps4rails.geocode(address);
...

这在嵌入式 javascript 中不起作用。事实上，如果我进入 Chrome 控制台并键入Gmaps4Rails，则 javascript 中的对象没有函数geocode（请参见下文）。

问题：有没有办法Gmaps4rails.geocode(address) 从 javascript 中调用？

JAVASCRIPT 控制台输出：

function Gmaps4Rails() {
      this.map = null;
      this.visibleInfoWindow = null;
      this.userLocation = null;
      this.geolocationFailure = function() {
        return false;

      this.callback = function() {
        return false;
      };
      this.customClusterer = function() {
        return false;
      };
