Prototype - toArray() 方法

此方法别名到克隆，避免默认的迭代行为。

语法

array.toArray();

返回的值

返回一个新的克隆数组。

示例

<html>
   <head>
      <title>Prototype examples</title>
      <script type = "text/javascript" src = "/javascript/prototype.js"></script>
      
      <script>
         function showResult() {
            var arr = [3, 5, 6, 1, 20];
            var newArr = arr.toArray();
            alert("New Array : "  + newArr.toArray().inspect());
         }
      </script>
   </head>

   <body>
      <p>Click the button to see the result.</p>
