Storage APIs
removeStorage
Remove cached data by key from local storage.
Overview
my.removeStorage removes cached data from local storage. This is an asynchronous interface. Removing the webview embedded storage data will not remove the storage data of the Mini Program.
Sample Code
my.removeStorage({
key: 'currentCity',
success: function(){
my.alert({content: 'remove success'});
}
});
Parameters
| Property | Type | Required | Description |
|---|---|---|---|
key | String | Yes | Cache data key. |
success | Function | No | Callback function upon call success. |
fail | Function | No | Callback function upon call failure. |
complete | Function | No | Callback function upon call completion (to be executed upon either call success or failure). |
Usage Notes
- This is an asynchronous interface
- Storage is isolated between embedded webview and Mini Program
- Removing embedded webview storage does not affect Mini Program storage
- If the key does not exist, the operation will still succeed
