AS3：创建用于存储JSON数据的对象数组

Posted 2021-02-26

Notes to self: re-use this for other projects

private var _myObjArr:Array = new Array(); // array of objects
private var _stringAuthor:String;
private var _stringDate:String;
private var _stringText:String;
 
		/**
		 * Success handler after requesting JSON data from server
		 * 
		 * @param event Event 
		 * @return void
		 */
		private function onSuccess(event:Event):void
		{
			var loader:URLLoader = event.target as URLLoader;
			var data:Object = null;
 
			try { // get the raw JSON data 				
				data = JSON.decode(loader.data);
 
			} catch(e:Error) {
				trace("Error requesting document");
			}
 
			loader.close();
			loader = null;
 
			if (data !=null)
			{
 
				if (data.error)
				{
					trace(data.error);
 
				} else {
	            	// loop thru data	            
			for (var key:Object in data) {
 
			            _stringAuthor = '<p><span class="author">' + data[key].author + '</span></p>';
 
			            _stringDate = '<span class="date">' + data[key].date + '</span></p>';
 
			            _stringText = '<p><span class="text"> "' + data[key].text + '"</span></p>';			            
 
 
			             // save Author, Date, Text to an object array _myObjArr
			             var obj:Object = new Object();
			             obj.Author = _stringAuthor;
			             obj.Date = _stringDate;
			             obj.Text = _stringText;
			             _myObjArr.push(obj);
 
			}
 
				}
			}
 
		} // end onSuccess
 
// now that we got all our info saved, we can retrieve it later in other functions like:
 
			for(var i:uint = 0; i < _myObjArr.length; i++) {							
				_blogPost[i] = addBlogPosts();
				addChild(_blogPost[i]);
			}
 
// does this snippet help anyone?
