Simple 2 Dimensional Array
var grades = [[89, 77, 78],[76, 82, 81],[91, 94, 89]]; print(grades[2][2]);
Method 1
var numeric = [
['input1','input2'],
['input3','input4']
];
numeric[0][0] == 'input1';
numeric[0][1] == 'input2';
numeric[1][0] == 'input3';
numeric[1][1] == 'input4';
Method 2
var obj = {
'row1' : {
'key1' : 'input1',
'key2' : 'inpu2'
},
'row2' : {
'key3' : 'input3',
'key4' : 'input4'
}
};
obj.row1.key1 == 'input1';
obj.row1.key2 == 'input2';
obj.row2.key1 == 'input3';
obj.row2.key2 == 'input4';
Method 3
var mixed = {
'row1' : ['input1', 'inpu2'],
'row2' : ['input3', 'input4']
};
obj.row1[0] == 'input1';
obj.row1[1] == 'input2';
obj.row2[0] == 'input3';
obj.row2[1] == 'input4';
Creating a Multidimensional Array on Fly
var row= 20;
var column= 10;
var f = new Array();
for (i=0;i<row;i++) {
f[i]=new Array();
for (j=0;j<column;j++) {
f[i][j]=0;
}
}
Method to create a Javascript Multidimensional Array
Array.matrix = function(numrows, numcols, initial) {
var arr = [];
for (var i = 0; i < numrows; ++i) {
var columns = [];
for (var j = 0; j < numcols; ++j) {
columns[j] = initial;
}
arr[i] = columns;
}
return arr;
}
Sample Test Values
var nums = Array.matrix(5,5,0); print(nums[1][1]); // displays 0 var names = Array.matrix(3,3,""); names[1][2] = "Joe"; print(names[1][2]); // display "Joe"
