Add a Filter to the Observer (__ob__) in Typescript

I am trying to implement a filter using
this.Grid.option("dataSource").filter(x => x.Placeholder != null)

however, it doesn't seem to be working

when I run

console.log(this.Grid.option("dataSource"));

I receive

(72) [{…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, ob: Observer] 0: {ob: Observer} 1: Placeholder : (...) PlaceholderDescr : (...) RecordID : (...) ob : Observer {value: {…}, dep: Dep, vmCount: 0} get Placeholder : ƒ reactiveGetter() set Placeholder : ƒ reactiveSetter(newVal) get PlaceholderDescr : ƒ reactiveGetter() set PlaceholderDescr : ƒ reactiveSetter(newVal) get RecordID : ƒ reactiveGetter() set RecordID : ƒ reactiveSetter(newVal) proto : Object 2 : {ob: Observer}

Answer №1

Retrieve the DataSource instance by using ds = this.Grid.getDataSource() (official documentation)

Once you have the DataSource instance, you can apply filtering using the ds.filter(expr) method. For more detailed information, refer to the section on filtering data
