update function for settings

It is only possible to update the complete object like: this.settings = {....}

It is not possible to update an single parameter like:

this.settings.noDataMessage = "No User found for ..."

Hello,

I have the same problem again. Normal it works, but updating it into an arrow function like API call or timeout does not work:

Example:

ngOnInit() {
    setTimeout(() => {
      console.log("Not work!!");
      this.changeSettings("not work!");
    }, 2000);
    
      console.log("Work!!");
      this.changeSettings();
  }

  changeSettings(name: string) {
    this.mySettings.noDataMessage =  name;
    this.settings = Object.assign({}, this.mySettings)
  }

You are right. You can only change the whole object. You can of course get around this by having a separate object for your settings which you can change and then assigning a copy of this object to this.settings. That’s at least what I do in my application.

Lets say you create a object mySettings: mySettings = {} // remember to add all the properties you need You can then do some changes to it: e.g. mySettings.data.actions.add = false; You then need to assign a copy of it to this.settings: this.settings = Object.assign({}, mySettings)
