使用JavaScript覆盖Google Map API中标记弹出窗口上的默认文本？

Question

我正在使用以下代码在网页上使用其 API 在 Google 地图上的一些标记之间购买路线图。您也可以在FIDDLE 上查看。

现在我的问题是我想在当前谷歌显示默认地址的每个标记标签上显示我自己想要的文本，如下图所示。

我尝试了很多东西并用谷歌搜索，但无法在我的代码中添加此功能。那么这可以在那里写我自己的文字吗...???

演示文本按照他们的纬度显示：

var locations = [
    ['Ahsanabad Chowrangi', 25.001807, 67.123459, 1],
    ['Allah Wali Chowrangi', 25.007006, 67.076991, 2],
    ['Shafique Mor', 24.957115, 67.076278, 3],
    ['Sohrab Goth Flyover', 24.945176, 67.084069, 4],
    ['Ancholi', 24.940619, 67.080735, 5],

    ['Lalo Kheet Daak Khana Chowrangi', 24.900226, 67.044931, 10],
    ['Teen Hatti Bridge', 24.892076, 67.043592, 11],
    ['Gurumandar', 24.880923, 67.039432, 12],
    ['Numaish Chowrangi', 24.872733, 67.035963, 13],
    ['Jama Cloth Market', 24.859631, 67.015729, 14],
    ['City Court', 24.854257, 67.006481, 15],
    ['Tower', 24.848813, 66.996748, 16],
    ['Nagina Center', 24.825830, 66.979450, 17],

Answer 1

要更改为每个标记显示的文本，请在调用路线渲染器之前修改路线响应中该腿的start_address 属性。要同时获取最后一点，还要将end_address 属性设置为下一段结束标记的值。

  for (var leg = 0; leg < response.routes[0].legs.length; leg++) {
    response.routes[0].legs[leg].start_address = markerText[instance * 9 + leg][0] + "<br>instance=" + instance;
  }

（上面的代码假定一个数组markerText 包含您希望为每个标记显示的文本）。
