my.setStorage

2021-07-21 11:23

Store the data with a specified key in the local cache. This will overlaps\ the original data using the same key.

This is an asynchronous interface.

Support the isolation of webview-embedded storage and the Mini Program storage. Specifying key storage data in embedded webview does not overlap the data corresponding to the same key of the Mini Program itself.

Sample Code

copy

my.setStorage({
  key: 'currentCity',
  data: {
    cityName: 'London',
    adCode: '330100',
    spell: ' London',
  },
  success: function() {
    my.alert({content: 'Set Success'});
  }
});

Parameters

Property	Type	Required	Description
key	String	Yes	Cache data key.
data	Object/String	Yes	Data to be cached.
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).

Note: When a single data is converted into a string, the string length is maximum 200*1024. For the same user, the cache of one Mini Program has an upper limit 10MB.
