You could do something like this in javascript
var data = [
[1, 2],
[3, 4],
[5, 6]
];
var getPos = function(elem, data) {
var result="";
data.forEach(function(value, index) {
value.forEach(function(v, i) {
if (v == elem) result += (index + 1) + '-' + (i + 1);
});
});
return result;
}
console.log(getPos(5, data));
solved how to get the position of a number in matrix?
