我一直在试图让JSON正与AS3有一段时间了,但无济于事。我不断收到以下错误,当我得到的JSON回来:
类型错误:错误#1034:类型强制失败:无法转换对象@ 26331c41到数组
。我试图改变变量jsonData对象,它修正了错误的数据类型,但我不完全知道我怎么能分析数据。

公共类DataGrab扩展Sprite {
公共职能DataGrab(){
}
公共职能的init(资源:字符串):无效{
VAR装载机:的URLLoader =新的URLLoader();
VAR要求:的URLRequest =新的URLRequest(资源);
loader.addEventListener(引发Event.COMPLETE,的onComplete);
loader.load(要求);
}
私有函数的onComplete(五:事件):无效{
VAR装载机:的URLLoader =的URLLoader(e.target);
VAR jsonData:阵列= JSON.de code(loader.data);
跟踪(jsonData);
}
}
}
解决方案
当你有 jsonData 变量作为
对象你是正确的
。遍历该变量,你可能只是做这样的事情的所有属性:
VAR jsonData:对象= JSON.de code(loader.data);
对于(VAR我:字符串中jsonData)
{
迹第(i +:+ jsonData [I]);
}
如果你想检查对象包含您可以使用类似的特定属性:
VAR hasFooProperty:布尔= jsonData.hasOwnProperty(fooProperty);
I've been trying to get JSON working with AS3 for a while now, but to no avail. I keep getting the following error when I get the JSON back:
TypeError: Error #1034: Type Coercion failed: cannot convert Object@26331c41 to Array.
I've tried changing the datatype of the variable "jsonData" to object, which fixes the error, but I'm not entirely sure how I can parse the data.

var loader:URLLoader = URLLoader(e.target);
var jsonData:Array = JSON.decode(loader.data);
trace(jsonData);
}
}
}
解决方案
You were correct when you had the jsonData
variable as an Object
. To iterate through all the properties of that variable you could just do something like this:
var jsonData:Object = JSON.decode(loader.data);
for (var i:String in jsonData)
{
trace(i + ": " + jsonData[i]);
}
If you wanted to check if the object contained a specific property you could use something like:
var hasFooProperty:Boolean = jsonData.hasOwnProperty("fooProperty");
