Arcgis Server for JavaScript API之自定义InfoWindow

各位看到这个标题不要嫌烦，因为本人最近一直在研究相关的问题，所以相关文章也只能是这些，同时希望看过我的文章的朋友，我的文章能够给你帮助。

在前面的两篇相关的文章里面，实现InfoWindow是通过div的东西实现的，本文要讲的是通过集成InfoWindowBase实现infowindow的。实现后InfoWindow主要修改了arcgis原来的样式，并加入了InfoWindow出界的处理。

源代码奉上：

myInfoWindow/InfoWindow.js

  return declare([InfoWindowBase, Evented],

  {

  constructor: function(parameters)

    {

      lang.mixin(this, parameters);
