'var'为 null 或不是对象

该代码在 Firefox 中运行良好，但在 IE8 中不行。我收到错误：“地址”为空或不是对象。

已经用谷歌搜索好几天了，无法得到关于如何修复/调试这个问题的明确答案。希望 stackoverflow.com 能够提供帮助。

var latlng = [
      {
address: new GLatLng(-6.1364941,106.8000411),
marker0: myIcon0
},
      {
address: new GLatLng(-6.1364941,106.8000411),
marker0: myIcon0
},
      {
address: new GLatLng(1.3520831,103.8198361),
marker0: myIcon0
},
      {
address: new GLatLng(14.06666671,121.33333331),
marker0: myIcon
},
    ];
  var markers = []; 
  for ( var i = 0; i < latlng.length; i++ )
    {
      var marker = new GMarker( latlng[ i ].address, latlng[ i ].marker0 );
      map.addOverlay( marker );
      markers[i] = marker;
    }
    $(markers).each(function(i,marker){ 
      GEvent.addListener(marker,"click", function(){ 
        // map.panTo(marker.getLatLng());
        map.setCenter(marker.getLatLng(), 10);
        marker.openInfoWindowHtml($('.view-display-id-attachment_1 .views-row-'+(i+1)).html(), {maxWidth:200});
      });
      $("<li />") 
        .html($('.view-display-id-attachment_1 .views-row-'+(i+1)).html()) 
        .click(function(){ 
          map.setCenter(marker.getLatLng(), 10);
          marker.openInfoWindowHtml($('.view-display-id-attachment_1 .views-row-'+(i+1)).html(), {maxWidth:200}); // custom balloon text
          // alert($('.view-display-id-attachment_1 .views-row-'+(i+1)).html()); // VIEWS ROW COUNT DEBUG
        }) 
        .appendTo("#wtb-list");
    });

The code works fine in Firefox, but not in IE8. I'm getting an error: 'address' is null or not an object.

Have been googling for days and couldn't get a clear answer on how to fix/debug this. Hope stackoverflow.com can help.

var latlng = [
      {
address: new GLatLng(-6.1364941,106.8000411),
marker0: myIcon0
},
      {
address: new GLatLng(-6.1364941,106.8000411),
marker0: myIcon0
},
      {
address: new GLatLng(1.3520831,103.8198361),
marker0: myIcon0
},
      {
address: new GLatLng(14.06666671,121.33333331),
marker0: myIcon
},
    ];
  var markers = []; 
  for ( var i = 0; i < latlng.length; i++ )
    {
      var marker = new GMarker( latlng[ i ].address, latlng[ i ].marker0 );
      map.addOverlay( marker );
      markers[i] = marker;
    }
    $(markers).each(function(i,marker){ 
      GEvent.addListener(marker,"click", function(){ 
        // map.panTo(marker.getLatLng());
        map.setCenter(marker.getLatLng(), 10);
        marker.openInfoWindowHtml($('.view-display-id-attachment_1 .views-row-'+(i+1)).html(), {maxWidth:200});
      });
      $("<li />") 
        .html($('.view-display-id-attachment_1 .views-row-'+(i+1)).html()) 
        .click(function(){ 
          map.setCenter(marker.getLatLng(), 10);
          marker.openInfoWindowHtml($('.view-display-id-attachment_1 .views-row-'+(i+1)).html(), {maxWidth:200}); // custom balloon text
          // alert($('.view-display-id-attachment_1 .views-row-'+(i+1)).html()); // VIEWS ROW COUNT DEBUG
        }) 
        .appendTo("#wtb-list");
    });

问题就在这里：

marker0: myIcon
},  //<-- here!
    ];

数组声明末尾的尾随逗号会给 IE8 带来问题，请将其删除:)其他浏览器...“忽略？”在大多数情况下，IE 总是会出错。

The issue is here:

marker0: myIcon
},  //<-- here!
    ];

that trailing comma at the end of your array declaration will give IE8 issues, remove it :) Other browsers..."overlook?" this in most cases, IE will always error on them.
