对 Flex 的 iframe Javascript 调用

Question

我有一个 flex 应用程序，顶部有一个 iframe。

我想从 iframe 调用以使用 javascript 进行 flex。

到目前为止，我已经尝试过：

这是包含嵌入在 ROOT 文档中的 swf 的 Object

    <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
        id="IPRS_Dispatcher" width="1400" height="1000"
        codebase="http://fpdownload.macromedia.com/get/flashplayer/current/swflash.cab">
        <param name="movie" value="DispatcherMain.swf" />
        <param name="quality" value="high" />
        <!-- <param name="bgcolor" value="${bgcolor}" /> -->
        <param name="allowScriptAccess" value="sameDomain" />
        <param name='flashVars' value='strLang=english&strIPRSSrvHost=&strGPSSrvHost=192.168.1.130&strGPSSrvSoapPort=8081&strGPSSrvFwdPort=26000&strLoginMode=simple&strSOSSrvHost=192.168.1.80&strSOSSrvSoapPort=8082&strSOSSrvFwdPort=26001&strSOSLoginMode=simple&strUserSIP=&strUserPswd=&nDelayForMapReadySecs=10&nGPSUpdatesRateSecs=120&nGPSSubscriptionsIntervalMinutes=10&nLat=35.0&nLng=32.5&nZoomLevel=5&strClientServiceVersion=2.1.36.19&nPathDotsSize=1&nPathWidth=5&bHideAnnounce=false&bHideEmergencyPan=true&strMapMarkerLabelMode=name&key=ABQIAAAAYbXZyR09wFj6QsiYucHpGxQEO34WZEWuIFq1A7yobGXPE-K5exQV9ZYR6NIkF8LCR8wsYvlhOIYsfA' />
        <embed id="IPRS_Dispatcher2" src="DispatcherMain.swf"
            flashVars='strLang=english&strIPRSSrvHost=&strGPSSrvHost=192.168.1.130&strGPSSrvSoapPort=8081&strGPSSrvFwdPort=26000&strLoginMode=simple&strSOSSrvHost=192.168.1.80&strSOSSrvSoapPort=8082&strSOSSrvFwdPort=26001&strSOSLoginMode=simple&strUserSIP=&strUserPswd=&nDelayForMapReadySecs=10&nGPSUpdatesRateSecs=120&nGPSSubscriptionsIntervalMinutes=10&nLat=35.0&nLng=32.5&nZoomLevel=5&strClientServiceVersion=2.1.36.19&nPathDotsSize=1&nPathWidth=5&bHideAnnounce=false&bHideEmergencyPan=true&strMapMarkerLabelMode=name&key=ABQIAAAAYbXZyR09wFj6QsiYucHpGxQEO34WZEWuIFq1A7yobGXPE-K5exQV9ZYR6NIkF8LCR8wsYvlhOIYsfA' 
            width="1400" height="1000" name="IPRS_Dispatcher" align="middle"
            play="true"
            loop="false"
            quality="high"
            allowScriptAccess="sameDomain"
            type="application/x-shockwave-flash"
            pluginspage="http://www.adobe.com/go/getflashplayer"> <!-- bgcolor="${bgcolor}" -->
        </embed>
</object>

我已经为我想要公开的函数添加了 addcallback

ExternalInterface.addCallback("sendToFlash", callFromJavaScript);

仅供参考

  public function callFromJavaScript(str):void
  {
  LogAddItem( 30, str);
  }

在我的 IFRAME 中我添加了该功能

function callToFlash(str) 
{
  var swf = parent.top.$("#IPRS_Dispatcher");
  var bool = swf.sendToFlash(str);
}

现在 chrome 出现错误 - Uncaught TypeError: Object [object Object] has no method 'sendToFlash'

25/06/2012 更新 - console.log(swf)

的输出

Answer 1

你能跑吗：

function sendToActionscript(str) 
{
  var swf = jQuery("#IPRS_Dispatcher", parent.document);
  console.log('step1');
  console.log(swf);
  console.log('step2');
  console.log.(swf.html());
  console.log('step3');

  swf.LogAddItem(30, str);
  console.log('step4');
}

好的，下一个调试步骤：运行这个：

function sendToActionscript(str) 
{
  var swf = parent.top.$(“#IPRS_Dispatcher”);
  console.log('step1');
  console.log($);
  console.log('step2');
  console.log.(jQuery);
  console.log('step3');
  console.log(parent.document);
  console.log('step4');
}

step4 

好的，现在就试试吧

function sendToActionscript(str) 
{
  var swf = parent.top.$(“#IPRS_Dispatcher”);
  swf.LogAddItem(30, str);
}

您的 flex 应用程序中存在错误

终于解决了

    // get flash movie object
var flashMovie;
function init() {
   if (document.getElementById) {
      flashMovie = parent.document.getElementById("IPRS_Dispatcher");
   }
}

// wait for the page to fully load before initializing
window.onload = init;

function callToFlash(str) 
{
  var bool = flashMovie.sendToFlash(str);
}

我认为在初始化之前等待页面完全加载是解决方法。

你也可以使用http://api.jquery.com/ready/

$(document).ready(init);

在 DOM 初始化后让它工作。
