搜索2D阵列最干净的方法？

Question

我能想到的最简单的方法是for循环:

var arr=[["hey","oh"],["scar","tissue"],["other","side"]];
var query="scar";
for(var z=0;z<arr.length;z++){
   if(arr[z].indexOf(query) !== -1){
      //Found
      break;
   }
}

有没有其他方法可以在2D数组中搜索字符串？

Answer 1

var arr = [["hey","oh"],["scar","tissue"],["other","side"]];
var flat = [].concat.apply([], arr);
var col = flat.indexOf(query);
var row = -1;
if (col != -1) // found, now need to extract the row
  while (arr[++row].length <= col) // not this row
    col -= arr[row].length; // so adjust and try again
