Flex in Visual force page

Flex in Visual force page: 

   This example is the combination of different languages such as Flex, Visual Force, Apex class and JavaScript. We are fetching the all documents and displaying in tree format. For this we need Flex SWF file we can download on this link http://wiki.apexdevnet.com/images/f/fd/TreeSample.swf

After download this SWF file upload in Static resource and used in VF page. We have written controller to get all parent and child documents and set in Visual force page.

Following are the code for this application.

VF page:

<apex:page controller="DocumentController" id="myPage">

<script>

var jsFolders = [];

var flexApp;

var docId, sfolderId, dfolderId, btnMove;

function getMyApp(appName) {

  if (navigator.appName.indexOf("Microsoft") != -1) {

    return window[appName];

  } else {

    return document[appName];

  }

}

function flexIsReadys() {

  flexApp = getMyApp("FlexFiles");

  flexApp.initApp(jsFolders);

}

function moveDocument(moveData) {

  docId.value = moveData.docId;

  sfolderId.value = moveData.sfolderId;

  dfolderId.value = moveData.dfolderId;

  btnMove.click();

}

</script>
