Retrieve the index of a specific element in an array and then cut the array at that index (increment by 1 if you want to remove that element):
const elements = ['-p', 'player', '1', '--name', 'player1', 'name'];
var targetIndex = elements.indexOf("--name");
elements.slice(++targetIndex) // or simply targetIndex if you want to keep "--name"
function findNextElements(array, target) {
let result = [];
for (let index = 0; index < array.length; index++) {
if (array[index] === target) {
for (let nextIndex = index + 1; nextIndex < array.length; nextIndex++) {
result.push(array[nextIndex])
}
}
}
return result;
}
let array = ['-p', 'player', '1', '--name', 'player1', 'name']
console.log(findNextElements(array, '--name')) //Result: [ 'player1', 'name' ]
console.log(findNextElements(array, '-p')) //Result: [ 'player', '1', '--name', 'player1', 'name' ]Here, the script uses nested For loops to find the elements after a specified target in the array.
