在flex中取得本地路径名

采用flex与js之间的交互

找到html—template文件下的index.template.html插入

//关键代码
        
        
            function openBrowser() 
            { 
                document.getElementById("fileInput").click(); 
            } 
            
            
            function OnFileChange()
            {
            //getPath(document.getElementById("fileInput"));
            
            //alert("hello");
            //    alert(thisMovie("jzbdtc"));
                thisMovie("Jdgt").OnFileChange1(getPath(document.getElementById("fileInput"))); 
            //thisMovie("upload").OnFileChange(document.getElementById("fileInput").value);
                    
            }
            function getPath(obj)  //参数obj为input file对象
            {      
                if (window.navigator.userAgent.indexOf("MSIE")>=1)  
                 {  
                     obj.select();  
                   return document.selection.createRange().text;  
                  }  
                else if(window.navigator.userAgent.indexOf("Firefox")>=1)  
                {  
                   if(obj.files)  
                   {  
                     return obj.files.item(0).getAsDataURL();  
                    }  
                  return obj.value;  
                 }  
            }
          function thisMovie(movieName) 
          {
              if (navigator.appName.indexOf("Microsoft") != -1) {
                  return window[movieName];
              } else {
                  return document[movieName];
              }
          } 

<!--fileInput控件-->
        <input type="file" id="fileInput" style="0px;height:0px;" onchange="OnFileChange()" />  

再到你所要用mxml中插入

    private function init():void{     
                
                //注册JS回调,js调用flex
                ExternalInterface.addCallback("OnFileChange1" ,getSourcePathHandler);        
            }    
            private function openSocure():void{
                
                //flex调用JS中Browser函数
                
                ExternalInterface.call("openBrowser");
                
            }
            private function getSourcePathHandler(path:String):void{
                Alert。show(path);                
            }
