将位置坐标作为变量传递给Google地图 [英] Passing location coordinates to google maps as variable

问题描述

任何人都知道为什么这会起作用：

  var wickedLocation = new google.maps.LatLng（44.767778，-93.2775）; 
  

但这不会：

  var wickedCoords =44.767778，-93.2775; 
 var wickedLocation = new google.maps.LatLng（wickedCoords）; 
  

我尝试将经度和纬度作为单独的变量传递，并且也没有做到这一点。我怎样才能成功地将坐标作为变量传递？谢谢！

解决方案

在此示例中，您将两个不同的数值传递给构造函数，然后将新创建的对象分配给wickedLocation：

  var wickedLocation = new google.maps.LatLng（44.767778，-93.2775）; 
  

在此示例中，您将单个字符串值传递给构造函数，该构造函数需要两个不同的数字坐标：

  var wickedCoords =44.767778，-93.2775; 
 var wickedLocation = new google.maps.LatLng（wickedCoords）; 
  

数据类型完全不同。

<这就是说，如果你想将一个坐标表示为单个对象，你可以这样做：

  var myHome = {lat：44.767778，long：-93.2775}; 
 
 var yourHome = {lat：23,454545，long：-92.12121}; 
  

然后，当您需要从Google创建coords对象时，可以将数据作为单个参数派生自单个对象：

  var wickedLocation = new google.maps.LatLng（myHome.lat，myHome.long）; 
  

Anyone know why this will work:

var wickedLocation =  new google.maps.LatLng(44.767778, -93.2775);

But this won't:

var wickedCoords = "44.767778, -93.2775";
var wickedLocation =  new google.maps.LatLng(wickedCoords);

I tried passing the latitude and longitude as separate variables and that didn't do the trick either. How can I pass the coordinates successfully as a variable? Thanks!

解决方案

In this example, you are passing two distinct numerical values into a constructor and then assigning the newly created object to wickedLocation:

var wickedLocation =  new google.maps.LatLng(44.767778, -93.2775);

In this example, you're passing a single string value into a constructor that requires two distinct numerical coordinates:

var wickedCoords = "44.767778, -93.2775";
var wickedLocation =  new google.maps.LatLng(wickedCoords);

The data types are both completely different.

With that said, if you want to represent a coordinate as a single object, you can do so like this:

var myHome = { "lat" : "44.767778" , "long" : "-93.2775" };

var yourHome = { "lat" : "23,454545" , "long" : "-92.12121" };

Then when you need to create the coords object from Google, you can pass the data in as individual arguments derived from a single object:

var wickedLocation =  new google.maps.LatLng( myHome.lat, myHome.long );
