创建网格的JavaScript公式

Question

我想用JavaScript.I平铺一个对象网格，我已经忘记了这个公式，似乎在任何地方都找不到它：

            var width = 113;
            var height = 113;
            var col = 10;
            var row = 10;

            for ( j = 0; j < col; j ++ ) {
                 var object = new object();
                 object.position.x = 0 + width * j
                 // do i nee another loop here?
                 //add object to....
             }

这将返回按宽度间隔的10个对象的行，但我也希望列类似于10x10网格，就在JavaScript中的公式之后。

Answer 1

您可以嵌套两个for循环，如下所示：

var width = 113;
var height = 113;
var col = 10;
var row = 10;

var space = ...;

// Rows loop
for ( j = 0; j < row; j ++ ) {
     // For each column in the row
     for ( i = 0; i < col; i ++ ) {
         // j is the row index and i is the column index..
         var object = new object();
         object.position.x = (width + space) * i;
         object.position.y = (height + space) * j;
         // Add object to...
     }
 }
