Question

I need to check if array contains at least one empty elements. If any of the one element is empty then it will return false.

Example:

var my_arr = new Array(); 
my_arr[0] = ""; 
my_arr[1] = " hi ";
my_arr[2] = "";

The 0th and 2nd array elements are “empty”.

Answer 1

You have to check in through loop.

function checkArray(my_arr){
   for(var i=0;i<my_arr.length;i++){
       if(my_arr[i] === "")   
          return false;
   }
   return true;
}
