Question

嗨，我是谷歌地图api和javascript的新手我在google chrome js控制台得到一些说“未捕获的SyntaxError：意外的标识符”可以帮助它。 downloadxml.js来自geocodezip.com/scripts/downloadxml.js 和我的xml文件的例子是;

<marker lat="37.887793" long="32.500402" name="Necmeddin Erbakan Üniversitesi Rektörlüğü" cat="Üniversite" desc="<a href="http://www.konya.edu.tr"target="_blank">Necmeddin Erbakan Üniversitesi</a><br><img src="resimler/konyau.jpg" width="150" height="100" >" ico_wsize="20" ico_hsize="20" ico_wssize="20" ico_hssize="20" ico_icon="icons/university.png"/>

HTML;

这是错误：

      var point[i] = google.maps.LatLng(lat, lng);
      var names[i] = markers[i].getAttribute("name");
      var cat[i] = markers[i].getAttribute("cat");
      var desc[i] = markers[i].getAttribute("desc");

您正在将某些内容直接分配给数组项。你必须这样做，例如：

var point = google.maps.LatLng(lat, lng);

然后将该值推送到某个数组（如果必须收集这些点，名称......）
