问题描述

我是Google Maps API的新手.

I am a newbie in Google Maps API.

我有一个包含以下内容的XML文件:

I have a XML file that contains the following:

              <?xml version="1.0"?>
              -<Customers>-
              <Marker category="Production">
              <title lang="en">Invensys</title>
              <site_location>Neponset Avenue 22, Foxborough, Foxboro, MA, United States</site_location> 

              <cordinantes>42.066817,-71.24814</cordinantes>
              <site_status>Normal</site_status>
     </Marker>
          <Marker category="Production"><title lang="en">Yokogawa Japan</title> 
             <site_location>Shinjuku, Tokyo,Japan</site_location>
             <cordinantes>36.543915,136.629281</cordinantes>             
             <site_status>Critical</site_status>
             </Marker>
             </Customers>

这是JS文件,其中包含读取XML文件并将数据输入到数组的函数,该文件称为func.js.

And this is the JS file containing the function that reads the XML file and enters the data into an array, file is called func.js.

<script src="jquery.xml2json.js" type="text/javascript" language="javascript"></script>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>


    var markers = [];

  $.get('Customers.xml', function(xml) {
  var jsonObj = $.xml2json(xml);
    $.each(jsonObj.Marker, function(){
        var stat = this.site_status == "Critical" ? "redgoogle.png" : "green_marker.png";
        var latlng = new google.maps.LatLng (this.cordinantes);
             var mark = {
                    title:  this.title,
                    location: this.site_location,
                    cord: latlng,
                    icon: stat
                    }
            markers.push(mark);
    });
debugger;
}); 

此HTML文件包含地图&应该根据标记"数组的内容生成两个标记.

And this HTML file that contains the map & should generate two markers according to the content of the "markers" array.

 <!DOCTYPE html>
 <html>
  <head>
  <title>Simple Map</title>
   <meta name="viewport" content="initial-scale=1.0, user-scalable=no">
   <meta charset="utf-8">
   <style>
     html, body, #map-canvas {
     height: 100%;
     margin: 0px;
     padding: 0px
   }
   </style>
<script src="jquery.xml2json.js" type="text/javascript" language="javascript"></script>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script type='text/javascript' src='func.js'></script>
<script>
 markers;   
  var map;
 function initialize() {
  var mapOptions = {
   zoom: 3,
    center: new google.maps.LatLng(32.637929,-16.934395),
   mapTypeId: google.maps.MapTypeId.ROADMAP
 };
  map = new google.maps.Map(document.getElementById('map-canvas'),
    mapOptions);
}
       google.maps.event.addDomListener(window, 'load', initialize);
</script>
 </head>
 <body>
   <div id="map-canvas"></div>
   </body>
 </html>

在使用标记"数组中的数据来生成市场时,我需要帮助. 我该如何使用markers数组来做到这一点?

I need assistance in using the data inside the "markers" array in order to generate markets. How can I use the markers array in order to do that ?

谢谢.

推荐答案

Initialize函数中执行此操作(如果您确定此时标记已加载):

In the Initialize function do this (if your sure the markers have been loaded at this point):

for(var i=0; i< markers.length; i++){
    var marker = new google.maps.Marker({ position: markers[i].cord, map:map });
}

如果尚未加载标记,请创建如下函数:

If the markers have not been loaded create a function like this:

function AddMarkers(){
    for(var i=0; i< markers.length; i++){
        var marker = new google.maps.Marker({ position: markers[i].cord, map:map });
    }
}

并在$.get的回调中调用此函数,如下所示:

And call this function in the callback of your $.get like this:

 $.get('Customers.xml', function(xml) {
  var jsonObj = $.xml2json(xml);
    $.each(jsonObj.Marker, function(){
        var stat = this.site_status == "Critical" ? "redgoogle.png" : "green_marker.png";
        var latlng = new google.maps.LatLng (this.cordinantes);
             var mark = {
                    title:  this.title,
                    location: this.site_location,
                    cord: latlng,
                    icon: stat
                    }
            markers.push(mark);
    });

    AddMarkers();
    debugger;
}); 

这将添加您的标记,有关如何生成自定义图标的信息,请参见

That will add your markers, for information on how to generate a custom icon refers to

  1. GoogleMaps API参考

GoogleMaps图标

您可以完成功能AddMarkers来生成图标,等等

You can complete the function AddMarkers to generate the icons and so on
