i want to pick highest value from an array so i use math.max function it is working well when i run this only with one array but as i have two different array to first of all i want to join them together so i use concat function but it is not working.
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script type="text/javascript">
var maX=[6,1]
var miN=[10,20]
alert(Math.max.apply(maX.concat(miN))
</script>
</head>
<body>
</body>
</html>
apply receives two arguments: the "this" and the argument list. Try
Math.max.apply(null, maX.concat(miN) )
or
Math.max.apply(Math, maX.concat(miN) )
alert. Its better in many ways.The first argument to apply is the value of this, not a parameter. Try
Math.max.apply(Math, maX.concat(miN))
The following code concatenates two arrays:
var alpha = ["a", "b", "c"];
var numeric = [1, 2, 3];
// creates array ["a", "b", "c", 1, 2, 3]; alpha and numeric are unchanged
var alphaNumeric = alpha.concat(numeric);
The following code concatenates three arrays:
var num1 = [1, 2, 3];
var num2 = [4, 5, 6];
var num3 = [7, 8, 9];
// creates array [1, 2, 3, 4, 5, 6, 7, 8, 9]; num1, num2, num3 are unchanged
var nums = num1.concat(num2, num3);
The following code concatenates three values to an array:
var alpha = ['a', 'b', 'c'];
// creates array ["a", "b", "c", 1, 2, 3], leaving alpha unchanged
var alphaNumeric = alpha.concat(1, [2, 3]);
to concat two arrays: var joinedarray = array1.concat(array2)
then do max on the joinedarray EDIT: to do the Math.max on the array refference this answer: JavaScript: min & max Array values?
