SWFUpload.SWFObject Plugin
|
||
|
|
|
||
|
|
Summary:
|
||
|
|
This plugin uses SWFObject to embed SWFUpload dynamically in the page. SWFObject provides accurate Flash Player detection and DOM Ready loading.
|
||
|
|
This plugin replaces the Graceful Degradation plugin.
|
||
|
|
|
||
|
|
Features:
|
||
|
|
* swfupload_load_failed_hander event
|
||
|
|
* swfupload_pre_load_handler event
|
||
|
|
* minimum_flash_version setting (default: "9.0.28")
|
||
|
|
* SWFUpload.onload event for early loading
|
||
|
|
|
||
|
|
Usage:
|
||
|
|
Provide handlers and settings as needed. When using the SWFUpload.SWFObject plugin you should initialize SWFUploading
|
||
|
|
in SWFUpload.onload rather than in window.onload. When initialized this way SWFUpload can load earlier preventing the UI flicker
|
||
|
|
that was seen using the Graceful Degradation plugin.
|
||
|
|
|
||
|
|
<script type="text/javascript">
|
||
|
|
var swfu;
|
||
|
|
SWFUpload.onload = function () {
|
||
|
|
swfu = new SWFUpload({
|
||
|
|
minimum_flash_version: "9.0.28",
|
||
|
|
swfupload_pre_load_handler: swfuploadPreLoad,
|
||
|
|
swfupload_load_failed_handler: swfuploadLoadFailed
|
||
|
|
});
|
||
|
|
};
|
||
|
|
</script>
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
You must provide set minimum_flash_version setting to "8" if you are using SWFUpload for Flash Player 8.
|
||
|
|
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
|
||
|
|
or corrupt Flash Player installations will not trigger this event.
|
||
|
|
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
|
||
|
|
be used to prepare the SWFUploadUI and hide alternate content.
|
||
|
|
swfobject's onDomReady event is cross-browser safe but will default to the window.onload event when DOMReady is not supported by the browser.
|
||
|
|
Early DOM Loading is supported in major modern browsers but cannot be guaranteed for every browser ever made.
