Remove Json object from json array element

Question

var jsonArray = ["test", "test1", "test2"];
var matchedValue = "test1";

I want to remove remove and (matchedValue) from the JsonArray. How can i delete and return rest of the string

Expected output : ["test", "test2"];

What I am doing :

var setValue = JSON.parse(fetchMethodJsonArray);
dataRemoved = setValue.filter(function(el) {
              return el != fetchValue;
          });

It is not working

Please tell me the solution Thanks in advance.

Answer 1

 // Assuming this is your fetched data const fetchMethodJsonArray = [{ "val": "One" }, { "val": "Two" }, { "val": "Three" }]; var setValue = fetchMethodJsonArray; const dataRemoved = setValue.filter((el) => { return el.val !== "One"; }); console.log(dataRemoved);

Answer 2

Answer from what i got..

jsonArray.splice(jsonArray.indexOf('string_to_search'));

It will delete the found item and return remaining array.

You can use this:

const deleteObj = (data, column, search) => {
    let result = data.filter(m => m[column] !== search);

    return result;
}

When you want to remove an object from JSON array element use this method:

 const deleteObj = (data, column, search) => { let result = data.filter(m => m[column] !== search); return result; } const arr = [ { name: 'test', surname: 'test1' }, { name: 'test23', surname: 'newsname' }, { name: 'test23', surname: 'newsname' } ] const deleted = deleteObj(arr, 'name', 'test'); console.log(deleted);

In this sample, you will use filter method. Mozilla says about filter:

The filter() method creates a new array with all elements that pass the test implemented by the provided function.

If you are using NodeJs, You can use 'modernarray' which is an small and simple npm package.

https://www.npmjs.com/package/modernarray

Install it by npm install modernarray

let modernarray = require('modernarray');
let myarray = [{
  "val": "One"
}, {
  "val": "Two"
}, {
  "val": "Three"
}];
let outputArray2 = modernarray.popByValue(myarray,{val:"One"})
console.log(outputArray2)
