Web AppBuilder Custom Widget - Use setTimeout() with publishData()

XuanKuai — Thu, 30 Jan 2020 14:52:24 GMT

The publishData() function won't work inside setTimeout() in my custom widget - returns error: this.publishData() is not a function. But this.publishData() works fine alone. How to get this.publishData() work inside setTimeout()?

Xuan,

Your issue is going to be a scope issue. The "this" object inside your setTimeout function is not scoped to the widget so this.publishData is not a function. You need to hitch your setTimeout function using lang.hitch.

setTimeout(lang.hitch(this, function(){
  this.publishData(yourdata);
}), 200);‍‍‍
