俗话说：爱美之心，人皆有之。是的，没错，即使我只是一个做地图的，我也希望自己的地图看起来好看一点。在本文，给大家讲讲在Arcgis for javascript下如何自定义鼠标样式。
首先，说几个状态。1、鼠标在地图上面移动；2、按住鼠标左键拖拽鼠标；3、拉框放大地图；4、拉框缩小地图。
鼠标在地图上面时为
按住鼠标拖拽地图时为
拉框放大地图时为
拉框缩小地图时为
接下来，说说我的实现思路。
第一种状态，在地图加载完成时出现，代码：
map.on("load",function(){map.setMapCursor("url(cursor/default.cur),auto");});map.on("mouse-drag-start",function(){map.setMapCursor("url(cursor/pointer.cur),auto");
});
map.on("mouse-drag-end",function(){map.setMapCursor("url(cursor/default.cur),auto");
});var navToolbar = new esri.toolbars.Navigation(map); on(dom.byId("zoom_in"), "click", function(event){//拉框放大map.setMapCursor("url(cursor/zoom-in.cur),auto");map.on("mouse-drag-start",function(){map.setMapCursor("url(cursor/zoom-in.cur),auto");});navToolbar.activate(esri.toolbars.Navigation.ZOOM_IN);});on(dom.byId("zoom_out"), "click", function(event){//拉框缩小map.setMapCursor("url(cursor/zoom-out.cur),auto");map.on("mouse-drag-start",function(){map.setMapCursor("url(cursor/zoom-out.cur),auto");});navToolbar.activate(esri.toolbars.Navigation.ZOOM_OUT);});最后，操作结束后一切回归原始状态，代码如下：
navToolbar.on("extent-history-change", function(){navToolbar.deactivate();map.on("mouse-drag-start",function(){map.setMapCursor("url(cursor/pointer.cur),auto");});});<!DOCTYPE html>
