Insert input as raw javascript




a string to be interpreted as javascript code


An object of class "json"


As much as possible, the jaysire package has been designed to allow the user to write a behavioural experiment from R that runs through the browser using the jsPsych javascript library, with no need to write any javascript code. However, in some cases this will not be possible and the user may need to pass raw javascript code to the experiment (e.g., when specifying an "on_finish" callback function). To do so, the javascript should be specified as a string that is passed to insert_javascript(). What this does is assign the string to the S3 class "json", which in turn means that it will be written to the "experiment.js" file as is.
