| 2 | SWFUpload Graceful Degradation Plug-in
|
|---|
| 3 |
|
|---|
| 4 | This plugin allows SWFUpload to display only if it is loaded successfully. Otherwise a default form is left displayed.
|
|---|
| 5 |
|
|---|
| 6 | Usage:
|
|---|
| 7 |
|
|---|
| 8 | To use this plugin create two HTML containers. Each should have an ID defined. One container should hold the SWFUpload UI. The other should hold the degraded UI.
|
|---|
| 9 |
|
|---|
| 10 | The SWFUpload container should have its CSS "display" property set to "none".
|
|---|
| 11 |
|
|---|
| 12 | If SWFUpload loads successfully the SWFUpload container will be displayed ("display" set to "block") and the
|
|---|
| 13 | degraded container will be hidden ("display" set to "none").
|
|---|
| 14 |
|
|---|
| 15 | Use the settings "swfupload_element_id" and "degraded_element_id" to indicate your container IDs. The default values are "swfupload_container" and "degraded_container".
