Question

我正在尝试使用php或jquery将纬度和经度值加载到下面的Google Maps链接中，但是找不到做到这一点的方法。

https://maps.google.com/maps?q= 31.1033 ， 77.1722 ＆hl = es; z = 14＆output = embed

我在下面的 demo 中以引导程序模式创建了一个静态的google map iframe加载器。但我正在寻找的是动态地将纬度和经度添加到 q = 31.1033,77.1722 中。我在数据库中创建了2个列，我想将这些值添加到 q = $ lat，$ lon 中，但是如果有人有任何想法，将不胜感激。

	 $('#myModalmap').on('shown.bs.modal', (function() {
      var mapIsAdded = false;
    
      return function() {
        if (!mapIsAdded) {
            
          $('.modal-body').html('<iframe src="https://maps.google.com/maps?q=31.1033,77.1722&hl=es;z=14&amp;output=embed" width="100%" height="400" frameborder="0" style="border:0"></iframe>');
    
          mapIsAdded = true;
        }    
      };
    })());

要动态声明纬度或经度，您可以将查询数据存储到数组中：

var latlong = [{lat: 31.1033, long:77.1722},{lat: 38.1033, long: 74.1722}];

您可以根据选择更改值来进行操作：

var i=1;
$('.modal-body').html('<iframe src="https://maps.google.com/maps?q='+latlong[i].lat+','+latlong[i].long+'&hl=es;z=14&amp;output=embed" width="100%" height="400" frameborder="0" style="border:0"></iframe>');

示例：

var latlong = [{lat: 31.1033, long:77.1722},{lat: 38.1033, long: 74.1722}];
var i=$('select#coordinatechoice').val();

$("select#coordinatechoice").change(function(){
  i=$('select#coordinatechoice').val();
  init();
});

function init(){
$('#myModalmap').on('shown.bs.modal', (function() {
      var mapIsAdded = false;
    
      return function() {
        if (!mapIsAdded) {
            
          $('.modal-body').html('<iframe src="https://maps.google.com/maps?q='+latlong[i].lat+','+latlong[i].long+'&hl=es;z=14&amp;output=embed" width="100%" height="400" frameborder="0" style="border:0"></iframe>');
    
          mapIsAdded = true;
        }    
      };
    })());
}
init();
