Can't access array in nested immutable object

Question

Do that

render() {
        var elems = this.props.items.course_list;
        console.log(elems);
        return (
          <div>

          </div>
        )
      }

Result:

Try access to course_list by this:

render() {
        var elems = this.props.items.course_list;
        console.log(elems.course_list;);
        return (
          <div>

          </div>
        )
      }

Get undefined.

Have object course_list that include array course_list, I can't access to this array

This screen for

var elems = this.props.items; console.log(elems);

The ; within the console.log() is not valid, is it a typo? — Alex K.

To access course_list from elems, it should be declared as elems = this.props.items — emerson.marini

You may need to convert the immutable object to a javascript object ot access the inner elements. In that case use getIn(). I hope it helps

var mystore = state.getIn(['incomeProfileList'])['course_list']; 
var copy = Object.assign({}, mystore); 
console.log(copy.course_list);

import Immutable from 'immutable'

Егор Кротенко Over a year ago

const mapStateToProps = function(state) {   var mystore = state.toArray(); //  console.log(mystore[6]);   return {      items: mystore[6]         };  }

this is how I get data

I have seen this, I am just thinking. maybe you can try state.toJS() and then see how you return item

Егор Кротенко Over a year ago

what console.log must be to state?

Shubham Khatri Over a year ago

so I said try var mystore = state.toJS() and then; try to get item from mystore. console.log(mystore) and share me the result.
