How do you pass data to a previous view?

[reedrichards]

If you want to pass data on a navController.pop, the solution proposed by @aaronksaunders works very well

[SOLVED] Ionic navController pop with params

pass in a callback when transitioning // callback... myCallbackFunction = function(_params) { return new Promise((resolve, reject) => { resolve(); }); } // push page... this.navController.push(OtherPageComponent, { callback: myCallbackFunction }); in the OtherPageComponent this.callback = this.navParams.get("callback") this.callback(param).then(()=>{ this.navController.pop(); });
