Javascript数组的使用

<script type="text/javascript">


  var banana = "香蕉";


  var fruit = new Array(3);
   fruit[0] = "西瓜";
   fruit[1] = "苹果";
   fruit[2] = "橙子";
   fruit.push("apple");
   fruit.push("orange");
   fruit.push(banana);
  
  for(var i = 0 ;i < fruit.length ; i++)
  {
     document.writeln("fruit[" + i + "] = " + fruit[i] + "<br/>");
   }


  var number = new Array(12,22,32);
  
  for(var j = 0 ; j < number.length ; j++)
  {
     document.writeln("number[" + j + "] = " + number[j] + "<br/>");
   }
  
  var names = ["张三","李四","王五"];


  for(var k = 0 ; k < names.length ; k++)
  {
     document.writeln("name[" + k + "] = " + names[k] + "<br/>");
   }
