question:

[
{
"project_id": 1,
"project_name": "CDP",
"role": "PL"
},
{
"project_id": 2,
"project_name": "Admincer",
"role": "PM"
},

I want to use some method to add the "project_id" attribute among the above three attributes to another array.

My thoughts are: 1. First, if I could copy the "project_id" attribute of this array to the second nested JSON array, that would be fine.

What I found:

const obj = {
"project_id": 1,
"project_name": "CDP",
"role": "PL"
};;
const objCopy = {
"start_time": "09:00:00",
"end_time": "18:00:00",
"rest_time": "01:00:00",
"worked_time": "08:00:00",
"is_wfh": true,
"id": 1, 1,
"work_day_id": 45,
"time_cards": [
{
... obj
}
]
};;
console.log (objCopy);

I found I could replicate it like this. I tried the above code in Chrome console. The array is copied, but the entire object is copied. I just want to copy the attribute of project_id.

I want to create a new property called "prj_name" in this array and display only that property in Vuetify.

async fetchWorkerTimeCard() {
  try {
    this.worker_data = [] 
    await this.$axios.$get('/worker_time_card', {
      params: {
        work_date: this.calendarVal
      }
    }).then(data => {
      this.worker_data = data
    })
    var projects = await this.fetch_worker_projects()
    console.log(projects)
  } catch (error) {
    console.log(error)
    this.worker_data = []
  }
},
