Exploring nested objects within an instance

I'm facing an issue with accessing a variable object within my main object. I am able to access 'start', 'end', and 'category' without any problem, but I am unsure how to access the variable Object in my Angular web app development project (not AngularJS).

The object is retrieved from...

<form #f="ngForm" (ngSubmit)="onSubmit(f)" novalidate>
<md-slider
    ngModel
    required
    #k="ngModel"
    [name]="k"
    [disabled]="false"
    [invert]="invert"
    [max]="10"
    [min]="3"
    [step]="1"
    [thumb-label]="true"
    [ngModel]="value"
    [vertical]="vertical">
</md-slider>
</form>

and k is initialized in ngInit, but my challenge lies in accessing this 'object'.

Object {start: "2011-01-01", end: "2017-06-27", [object Object]: 5, category: ""}

Thank you!!!

RE-EDIT I am trying to access my JSON data in this function.

getBestSeller(filter: JSON) {
    const k = filter['k'];
    console.log("object -> ", filter['object']) //ERROR, 'object' undefined
    //...
}

Answer №1

If you want to iterate over the properties of an object in JavaScript, you can use the for..in loop.

var obj =  {start: "2011-01-01", end: "2017-06-27", [object Object]: 5, category: ""}

for (var prop in obj) { 

      console.log(prop==='[object Object]' && obj[prop]); //will give [object object] value
 }

Answer №2

For those seeking a helpful tool, I suggest checking out the Underscore.js library. By utilizing functions like _.find(), you can easily access various JavaScript options familiar from other programming languages.
