ArcGIS Server Flex API 自定义缩放控件的级数[代码]

直接上代码，首先，在map控件中增加Load事件函数，代码如下：

<esri:Map >

对应的addLODs()函数定义如下：

private function addLODs():void
{
// make sure the resolution makes sense for tile schema of the base layer
// both resolution and scale are required fields
// About NaN: The lods are automatically sorted based on scale, so setting level isn't necessary.
    var lods:Array = myMap.lods; 
    // 下面注释代码为增加缩放级数               
/*
　　 lods.push(new LOD(NaN, 0.6, 3000));
    lods.push(new LOD(NaN, 0.3, 1500));
    lods.push(new LOD(NaN, 0.1, 500));
*/
　　 // 下面代码为删除缩放级数 
    lods.splice(0, 5);                    
    myMap.lods = lods;
}

 1 private function addLODs():void
 2             {
 3                 // make sure the resolution makes sense for tile schema of the base layer
 4                 // both resolution and scale are required fields
 5                 // About NaN: The lods are automatically sorted based on scale, so setting level isn't necessary.
 6                 var lods:Array = myMap.lods;                
 7                 /*lods.push(new LOD(NaN, 0.6, 3000));
 8                 lods.push(new LOD(NaN, 0.3, 1500));
 9                 lods.push(new LOD(NaN, 0.1, 500));
10                 lods.pop();
11                 lods.pop(); */
12                 lods.splice(0, 5);                    
13                 myMap.lods = lods;
14             }v的
