Startup parameters

Last Updated: Sep 18, 2021

The appearance and action of the HTML5 container during running are controlled by a group of parameters. The startup parameters can be specified when you start a new instance or call pushWindow, for example:

  1. alipays://platformapi/startapp?appId=20000067&

In addition, the first URL of a new instance can carry a magic parameter webview_options. The content will be fetched by the container and transferred to the container.

  1. ?webview_options=showOptionMenu%3DNO&startMultApp%3DYES
  2. // urlencode('showOptionMenu=NO&startMultApp=YES') => showOptionMenu%3DNO&startMultApp%3DYES

The startup parameters passed through by the client can be obtained by the frontend through AlipayJSBridge.startupParams or jsapi:getStartupParams.
