javascript - 如何通过点击谷歌地图中的标记来显示图像

Question

我有以下带有三个标记的代码，如何单击其中一个标记来加载图像？

我会尝试输入 <div>但它不起作用。

有什么想法吗？

  <script type = "text/javascript">
  // Define your locations: HTML content for the info window, latitude, longitude
  var locations = [
  ['<h4>Tj</h4>Lat:32.509604, Lon:-117.020600', 32.509604, -117.020600, "<div><img width='254' height='355' src='http://descubretijuana.com/sites/default/files/mainrotatorpanoramica.jpg'</div>"],
  ['<h4>Rm</h4>Lat:32.565038, Lon:-116.021757', 32.565038, -116.021757, "<div> <img width='254' height = '355' src='https://upload.wikimedia.org/wikipedia/commons/thumb/2/2f/LaRumorosa.jpg/220px-LaRumorosa.jpg'</div>"], 
  ['<h4>Mxl</h4>Lat:32.624473, Lon: -115.452642', 32.624473, -115.452642, "<div> <img width='254' height='355' src='https://upload.wikimedia.org/wikipedia/commons/thumb/4/43/MexicaliMetroNight.jpg/275px-MexicaliMetroNight.jpg'</div>"]

  // Setup the different icons and shadows

Answer 1

此行仅从索引 0 添加 html。您的 HTML 图像代码位于索引 3 处。

infowindow.setContent(locations[i][0]);

所以用

更新该行

infowindow.setContent(locations[i][0] + locations[i][3]);

// Define your locations: HTML content for the info window, latitude, longitude
  var locations = [
  ['<h4>Tj</h4>Lat:32.509604, Lon:-117.020600', 32.509604, -117.020600, "<div><img width='254' height='355' src='http://descubretijuana.com/sites/default/files/mainrotatorpanoramica.jpg'</div>"],
