Question

我正在尝试在我的html页面手动输入的两个点之间找到路线，但我得到ZERO_RESULTS返回值。

用户输入两个位置src_address =“Tel Aviv”和dst_address =“Haifa”。

通过为每个地址调用geocoder.geocode两次来获取它们的几何位置。然后设置： src_latlng = results [0] .geometry.location; dst_latlng = results [0] .geometry.location;

然而，当要求路由器我得到ZERO_RESULTS：

这是代码：

Answer 1

Google还没有针对以色列的Maps API覆盖范围，因此从directionsService.route函数调用返回了ZERO_RESULTS状态。

请参阅Google支持的地区here的地图覆盖范围详情工作表。电子表格的直接链接是here。

Answer 2

您可以使用此代码获取源和目的地之间的路线

function setRoute()
{
      var fromAddress=document.getElementById("txtfromAddress").value;
      var toAddress=document.getElementById("txttoAddress").value; 
      if(fromAddress!="" && toAddress!="")
      {
       if(!fromAddress && !toAddress)
       {
       alert('ROute not found');
       }
       GDir1.load("from: " + fromAddress + " to: " + toAddress);        


      }
      else
      {
        alert('Route Directions Required');
      }
}
