Component({
properties: {}
methods: {
onTap: function(){
var myEventDetail = {} // detail
var myEventOption = {} //
this.triggerEvent("myevent", myEventDetail, myEventOption)
}
}
})this is a custom event given in the official document, which is triggered by triggerEvent, so if I want to pass a custom component parameter to this" myevent", I don"t seem to see the method.
