使用Lodash _.find根据属性从数组获取对象

Question

I have an array of objects, say memberToChange.checkboxes: ICheckbox[] like this:

Now, I have a variable, say internalNumber: string which has the value "3419". I want to get the object from the array of objects where the internalNumber matches the label property. Ultimately, I want to set the value attribute of that object to true.

My code is:

let checkboxes = _.find(scope.selectedMembers, (member: IMember) => member.member.uuid === memberId).checkboxes;     //gives me array of checkboxes.  
let checkboxToChange = _.find(memberToChange.checkboxes, function(checkbox: ICheckbox){
  return (checkbox.label === internalNumber);
}); //gives me null, moreover, even a console.log inside the second find doesn't print. I'm thinking the two consecutive _.find statements are messing something up, not sure what.

For reference, this is my ICheckbox interface:

export interface ICheckbox {
    label: string;
    sublabel?: string;
    value: boolean;
    numberUuid: string;
}

I would expect that for internalNumber 3419, it should return me the second object from the array. But it returns undefined. I'm not sure what's going on here. If there is a better way to find and set the value to true in one go only, I'd be happy to know that as well. Any help is appreciated. Thank you.

Update:

After someone suggested using filter method of javascript, I tried this: (my scope is assigned to this)

scope.selectedMembers.filter(function(member) {
    if (member.member.uuid === memberId) {
      scope.memberCheckboxes = [];
      console.log('found member'); //prints 
      scope.memberCheckboxes = member.checkboxes;
      console.log(scope.memberCheckboxes); // print correctly, with checkboxes of the member
      scope.memberCheckboxes.filter(function(checkbox) {
        console.log('inside checkbox function'); //control doesnt even come here
        if (checkbox.label === intNum) {
          console.log('found checkbox'); // control doesnt come here 
        }
      });
    }
  });

Here, I don't understand why the first console.log inside scope.memberCheckboxes.filter doesn't print? Am I missing something obvious here?

Answer 1

By some reason your memberToChange.checkboxes (or member.checkboxes in your updated question) have no elements.

It is the only explanation why it does not work since your code is otherwise correct. The fact that console.log('inside checkbox function') does not print confirms that.
