與as3中的print_r類似的函數

Question

在php中，我們有方法print_r（）。

在as3中有什麼與打印出對象/數組類似的東西嗎？

Answer 1

I found this：

public function analyze(_obj):void { 
    var item:Object; 
    switch (typeof(_obj)){ 
     case "object": 
      write("<object>"); 
      write(_obj.toString()); 
      for each (item in _obj){ 
       analyze(item); 
      }; 
      write("</object>"); 
     break; 
     case "xml": 
      write("<xml>"); 
      write(_obj); 
      write("</xml>"); 
     break; 
     default: 
      write(_obj + " (" + typeof(_obj) + ")"); 
     break; 
    }; 
} // analyze() 
public function write(_obj):void{ 
    trace(_obj); 
} // END write()

退房[ObjectUtil.toString]（http://livedocs.adobe.com/flex/3/langref/mx/utils/ObjectUtil.html#toString())

Answer 3

下面是另一個示例：

public function rTrace(obj:*, tab:Number=0):void { 
     if(tab > 10) return; 
     for(var key:String in obj) { 
      if(typeof(obj[key]) == "object" || obj[key] is Array) { 
       tr(doTab(tab)+key+"["+typeof(obj[key])+"]= {"); 
       rTrace(obj[key], tab+2); 
       tr(doTab(tab)+"}"); 
      } else 
       tr(doTab(tab)+key+"["+typeof(obj[key])+"]="+obj[key]);     
     } 
    } 
    private function doTab(n:Number):String { 
     var out:String = ""; 
     for(var i:Number=0; i<n; i++) 
      out += " "; 
     return out;   
    }  
    private function tr(msg:String):void { 
     trace(msg); 
    } 

實例：

var test:Object = {id:"asdf", count:17, 
        childs:[1,2,7,39], tasks:{task_1:"test", task_2:true}}; 
rTrace(test); 

給出輸出：

tasks[object]= { 
    task_2[boolean]=true 
    task_1[string]=test 
} 
count[number]=17 
childs[object]= { 
    0[number]=1 
    1[number]=2 
    2[number]=7 
    3[number]=39 
} 
id[string]=asdf
