#NodesRef: invoke() method

Execute the UI method of the selected node.

Please note that the UI function is a function provided by the client, usually directly controlling UI functions, such as the play or stop of the player. invoke cannot be used to call a js function of a custom component.

#Syntax

invoke(options: Record<string, any>): SelectorQuery;

#Parameters

#options

The options parameter is a Record<string, any>, which contains the information needed for the execution of the UI method. Its key list is as follows:

• method

• A string, the name of the UI method to be called

• params (optional)

• A Record<string, any>, the parameters of the UI method to be called

• success (optional)

• A callback function that is called when the UI method is successfully executed, with the first parameter being the result returned by the UI method

• fail (optional)

• A callback function that is called when the UI method fails to execute, with the first parameter type being {code: number, data: any}, which contains the error code and error message returned by the UI method.

• If no fail callback function is provided, a red screen error will be generated when the UI method fails to execute.
