| 2 | SWFUpload.SWFObject Plugin |
| 3 | |
| 4 | Summary: |
| 5 | This plugin uses SWFObject to embed SWFUpload dynamically in the page. SWFObject provides accurate Flash Player detection and DOM Ready loading. |
| 6 | This plugin replaces the Graceful Degradation plugin. |
| 7 | |
| 8 | Features: |
| 9 | * swfupload_load_failed_hander event |
| 10 | * swfupload_pre_load_handler event |
| 11 | * minimum_flash_version setting (default: "9.0.28") |
| 12 | * SWFUpload.onload event for early loading |
| 13 | |
| 14 | Usage: |
| 15 | Provide handlers and settings as needed. When using the SWFUpload.SWFObject plugin you should initialize SWFUploading |
| 16 | in SWFUpload.onload rather than in window.onload. When initialized this way SWFUpload can load earlier preventing the UI flicker |
| 17 | that was seen using the Graceful Degradation plugin. |
| 18 | |
| 19 | <script type="text/javascript"> |
| 20 | var swfu; |
| 21 | SWFUpload.onload = function () { |
| 22 | swfu = new SWFUpload({ |
| 23 | minimum_flash_version: "9.0.28", |
| 24 | swfupload_pre_load_handler: swfuploadPreLoad, |
| 25 | swfupload_load_failed_handler: swfuploadLoadFailed |
| 26 | }); |
| 27 | }; |
| 28 | </script> |
| 29 | |
| 30 | Notes: |
| 31 | You must provide set minimum_flash_version setting to "8" if you are using SWFUpload for Flash Player 8. |
| 32 | The swfuploadLoadFailed event is only fired if the minimum version of Flash Player is not met. Other issues such as missing SWF files, browser bugs |
| 33 | or corrupt Flash Player installations will not trigger this event. |
| 34 | The swfuploadPreLoad event is fired as soon as the minimum version of Flash Player is found. It does not wait for SWFUpload to load and can |
| 35 | be used to prepare the SWFUploadUI and hide alternate content. |
| 36 | swfobject's onDomReady event is cross-browser safe but will default to the window.onload event when DOMReady is not supported by the browser. |
| 37 | Early DOM Loading is supported in major modern browsers but cannot be guaranteed for every browser ever made. |
