用仿ActionScript的语法来编写html5——第九篇，仿URLLoader读取文件

function readFile(){urlloader = new LURLLoader();urlloader.addEventListener(LEvent.COMPLETE,readFileOk);urlloader.load("../file/test.txt","text");}function readFileOk(){mytxt.text = urlloader.data;}

if(!file_exists($_POST["file"])){echo "";exit;}$file = fopen($_POST["file"],"r");$filemsg = "";while (!feof($file)) {$line = fgets($file);$filemsg = $line;}fclose($file);echo $filemsg;

function LURLLoader(){var self = this;self.objectindex = ++LGlobal.objectIndex;self.type="LURLLoader";self.loadtype = "";self.content = null;self.oncomplete = null;self.event = {};}LURLLoader.prototype = {addEventListener:function(type,listener){var self = this;if(type == LEvent.COMPLETE){self.oncomplete = listener;}},load:function (path,loadtype){var self = this;self.loadtype = loadtype;if(self.loadtype == "text"){$.post(LEGEND_FILE_PHP, {flg:"read",file:path},function(data){if(self.oncomplete){self.event.currentTarget = data;self.data = data;self.oncomplete(self.event);}});}}}
