I three arrays called matchingdata,boxes,paints array based on this three arrays, i am trying to filter the array.(nested v-for)

Now, I want to iterate the matchingdata array by comparing it with sname in boxes array. and Common value between matchingdata and boxes array is ""sname""

I tried above logic, and struck with computed property.

Expected Output:-

In List.vue component, i have {{ match.OverallStatus }} where that field, i want to show,(from the matchingdata array) when user clicked on checkbox.

Taking the ""sname"" the common value from the matchingdata array and the boxes array

Answer 1

As you're passing the sname property as a string via a prop to your List.vue component, you'll just need to use that string in your filter function.

matchingData() {
   return this.content.filter((a) => a.sname === this.sname)
},

I've tried this in your codesandbox link and it is giving some output - but I'm not clear enough on what you're trying to achieve to know if this is the intended outcome.

Just incase you're not aware the 'filter' function returns a new array. It's not going to return a 'true/false' which I feel you may be trying to do.
