locbtran Posted January 18, 2013 Share Posted January 18, 2013 I have an array, called, "myArray". Inside this myArray are 4 more arrays, "m0, m1, m2, m3".How do I access all the elements in all the array? Here's my code, : <!DOCTYPE html><html><head> <title></title></head> <body><script>var m0 = [0, 1, 2, 3, 4];var m1 = [5, 6, 7, 8, 9];var m2 = [10, 11, 12, 13, 14];var m3 = [15, 16, 17, 18, 19]; var myArray = [m0, m1, m2, m3]; for (var i = 0; i < myArray.length; i++) { for (var j = 0; j < ("m"+i).length; j++) { document.writeln(myArray[i][j]); }}</script></body></html> This code only give me the first 2 elements in each array.But, I would like to get all the elements in all the arrays. tks Link to comment Share on other sites More sharing options...
Don E Posted January 18, 2013 Share Posted January 18, 2013 You were pretty close.. just add myArray.length; to the second for loop... instead of ("m"+i).length; <!DOCTYPE html><html><head> <title></title></head> <body><script>var m0 = [0, 1, 2, 3, 4];var m1 = [5, 6, 7, 8, 9];var m2 = [10, 11, 12, 13, 14];var m3 = [15, 16, 17, 18, 19]; var myArray = [m0, m1, m2, m3]; for (var i = 0; i < myArray.length; i++) { for (var j = 0; j < myArray[i].length; j++) { document.writeln(myArray[i][j]); }} </script></body></html> Link to comment Share on other sites More sharing options...
