I am working with a 2D array that is structured as follows:
var numbers=[[1,2,3,4,5],[6,2,3,5,5],[9,8,3,4,9]]
Is there a way to determine the index value of elements in this two dimensional array?
I am working with a 2D array that is structured as follows:
var numbers=[[1,2,3,4,5],[6,2,3,5,5],[9,8,3,4,9]]
Is there a way to determine the index value of elements in this two dimensional array?
Here is a useful alternative:
let key = 5;
array.forEach(function(item, index){
item.forEach(function(subItem, subIndex){
if(subItem === key){
console.log("Index of parent item: " + index);
console.log("Index of child item: " + subIndex);
}
})
});
function searchArray(arr, element) {
var occurrences = [];
for(var i = 0; i < arr.length; i++)
for(var j = 0; j < arr[i].length; j++)
if(arr[i][j] == element)
occurrences.push(i+"*"+j);
return occurrences;
}
Testing the function with numbers array:
var numbers = [[1,2,3,4,5],[6,2,3,5,5],[9,8,3,4,9]];
var results = searchArray(numbers, 4);
console.log("found " + results.length + " occurrences: " + results);
found 2 occurrences: 0*3,2*3
