Javascript 无法在Wordpress页面上加载google地图API

我正试图在我的wordpress网站上显示我用谷歌地图API制作的地图。地图似乎有一半的时间都在加载。当它没有加载时，我会收到一条消息，提示在声明initMap（）函数之前调用了它。在一个类似的话题上有一些问题被问到，但我一直没能让它对我起作用

  <title>Salt City Map</title>

  <div id="map"></div>
  <style type="text/css">
  /* Always set the map height explicitly to define the size of the div
 * element that contains the map. */

#map {
  height: 650px;
  width: 100%;
}


/* Optional: Makes the sample page fill the window. */

html,
body {
  height: 100%;
  width: 100%;
  margin: 0;
  padding: 0;
}

  </style>
  <!-- Replace the value of the key parameter with your own API key. -->

谢谢。

试着这样声明initMap

function initMap(){
   var syr = {
      lat: 43.0466145,
      lng: -76.1555968
   };
.....
....



...
}

在之后访问的地点的循环中缺少分号

var place = visitedPlaces[i]

应该是

var place = visitedPlaces[i];

检查fi web控制台中是否有错误。这是我最初声明函数的方式，在阅读了另一篇stackoverflow文章后，我切换到window.initMap方法，希望它能改变在加载页面时声明函数的顺序。@Jesse try。。让我知道。。如果工作顺利的话。。否则。我们再看一看。。。但请检查web控制台错误提示。。可能你有…谢谢。有件事我不太明白。为什么有时贴图加载100%良好，没有错误。有时我会遇到两个“捕获语法错误：输入意外结束”错误和“initMap不是函数”错误。这更像是一种竞争条件，页面每次加载都不同，而不是语法问题。谢谢你的帮助！我可以看到您已经对函数进行了更改，并且去掉了initMap不是一个函数错误，但是我仍然得到了相同的错误，意外的标记var，因为您仍然缺少var place=visitedPlaces[I]之后的分号，所以您的脚本不会执行任何其他操作。

var place = visitedPlaces[i];
