在dom中移动时，Javascript会失去与flash的通信 [英] Javascript loses communication with flash when moved inside dom

问题描述

  var methodName4：String =startupload; 
 var instance4：Object = null; 
 var method4：Function = startupload; 
 var wasSuccessful4：Boolean = ExternalInterface.addCallback（methodName4，instance4，method4）; 
函数startupload（current_uploading_id）{
 
 / *如果还有更多照片要上传，则继续下一个* / 
 if（（max_photo_number  -  session_photos））
 {
 uploadthis（selected_photos，currently_uploading_id）; 
 
 
 code $ 
 
 $ b $ p 
 
 
 < div id =e_uploadclass =hidden> 
< div id =upload_container> 
  
 
 
  
 
 
 
 
 
 
 
  
 
 
 < / div> 
< / div> 
  
 Javascript：
当加载dom时：
  var cached_flash = $（'＃e_upload'）。html（）; 
 $（'＃e_upload'）。html（''）; 
 
通过javascript生成html时：
 $（cached_flash）.appendTo（full_ad.find（'＃e_upload_wrapper'））。show（）; 
  
就是这样。当我试图上传事端时，flash里面的startupload函数不再工作。
 
 
 
以这种方式调用Actionscript：
 
 
  / *发送回Flash * / 
 function thisMovie（movieName）{
 
 if（window.document [movieName]）{
 return window.document [movieName]; 
 
 if（navigator.appName.indexOf（Microsoft Internet）== -1）{
 if（document.embeds&& document.embeds [movieName]）
 return document.embeds [movieName]; 
 
 else if（navigator.appName.indexOf（Microsoft Internet）！=  -  1）
 {
 return document.getElementById（movieName）; 
} 
 
} 
 
 thisMovie（'fileref'）。startupload（currently_uploading_array_slot）; 
  
 Actionscript从内部调用javascript函数，但javascript不行。 
 $ b 
有什么问题？如何重新绑定startupload函数？
解决方案
你访问文档正文，但你的swf更深，所以直接访问：
 
 
 
所以不是 document.getElementById（movieName）但是 document.getElementById（e_upload）.getElementById（movieName ） 
 
Code inside Actionscript:
var methodName4:String = "startupload";
var instance4:Object = null;
var method4:Function = startupload;
var wasSuccessful4:Boolean = ExternalInterface.addCallback(methodName4, instance4, method4);
function startupload(currently_uploading_id) {

    /* If there is still more photos to upload, then proceed to next one */
    if((max_photo_number - session_photos))
    {
        uploadthis(selected_photos,currently_uploading_id);
    }
}
Html:
<div id="e_upload" class="hidden">
    <div id="upload_container">








    </div>
</div>
Javascript:
when dom is loaded:
var cached_flash = $('#e_upload').html();
$('#e_upload').html('');

When generating html via javascript:
$(cached_flash).appendTo(full_ad.find('#e_upload_wrapper')).show();
That's it. When i'm trying to upload somethin, startupload function inside flash is not working anymore.

Calling Actionscript this way:
/* Sending back to Flash */
function thisMovie(movieName) {

    if (window.document[movieName]) {
        return window.document[movieName];
    }
    if (navigator.appName.indexOf("Microsoft Internet") == -1) {
        if (document.embeds && document.embeds[movieName])
            return document.embeds[movieName];
    }
    else // if (navigator.appName.indexOf("Microsoft Internet")!=-1)
    {
        return document.getElementById(movieName);
    }

}

thisMovie('fileref').startupload(currently_uploading_array_slot);
Actionscript is calling javascript functions from inside just fine, but javascript is not.

What is the problem? How to rebind startupload function?
解决方案
you accessing document body, but your swf is deeper, so access it directly:

so not document.getElementById(movieName) but document.getElementById(e_upload).getElementById(movieName)
