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

Question

我正在使用下面的代码通过其网页上的API在Google Map上的某些标记之间购买路线图。您也可以在FIDDLE上查看它。

现在我的问题是，我想在每个标记标签上显示自己想要的文本，当前Google正在显示默认地址，如下图所示。

我尝试了很多事情并用谷歌搜索，但无法在我的代码中添加此功能。那有可能在这里写我自己的文字吗????

演示文本按其时时显示：

var locations = [
    ['Ahsanabad Chowrangi', 25.001807, 67.123459, 1],
    ['Allah Wali Chowrangi', 25.007006, 67.076991, 2],
    ['Shafique Mor', 24.957115, 67.076278, 3],

    ['City Court', 24.854257, 67.006481, 15],
    ['Tower', 24.848813, 66.996748, 16],

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，在路线响应中修改该腿的start_address属性。为了同样获得最后一点，还应将end_address属性设置为下一条腿的结束标记的值。

  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;
  }

（上面的代码假设一个数组markerText包含您希望为每个标记显示的文本）。
