problem description
these are the values I defined in iframe. How can I call these values in the parent component
the environmental background of the problems and what methods you have tried
at present, it is normal for vue and iframe to pass values to each other through postMessage. I would like to ask whether the parent component can get the value through ref, but not through postMessage. It means that if iframe does not trigger the value, the object value of iframe can be obtained in the parent component.
I hope the boss can take a look at it for me
