检查Id元素的JavaScript

var jewels = new Array() 
var index 
var rand 

var scard = [a1, a2, a3, b1, b2, b3, c1, c2, c3] 

    function generateBoard() { 

     for (var i = 0; i <= 8; i++) { 
      jewels[i] = new Array(); 

      var index = Math.floor(Math.random() * scard.length) 
      jewels[i] = scard[index] 
      console.log("I:" + i + jewels[i]) 
      var yy = scard.indexOf(scard[index]); 
      scard.splice(yy, 1); 
     } 
    } 

    function drawBoard() { 

     generateBoard() 
     var html = '<div class=Game_Background>' 

     for (var i = 0; i < 9; i++) { 

      rand = Math.floor(Math.random() * jewels.length) 
      html += '<div class="' + jewels[rand] + '" id="ship' + i + '" style="top:' + ((i * 12) + 135) + 'px; left:245px;" ></div>' 
      jewels.splice(rand, 1); 
     } 
     var newarray = [a1, a2, a3, b1, b2, b3, c1, c2, c3] 
    }

这里A1，A2，A3，B1，B2，B3，C1，C2，C3是CSS class.I使用newarray因为我拼接所有的阵列items.Now假设SHIP2的元素id是b3，b3位于newarray [5]。我如何检查这个（id元素被定位在数组中的索引号）？检查Id元素的JavaScript

你想在数组中的相应类名的位置？ – 2013-05-13 09:29:11

在这个例子中，你没有显示出所有这些变量是什么类型（a1，a2，a3，b1，b2，b3，c1，c2，c3）并且问题太抽象了，添加更多代码来查看所有情况并尝试更加明确。 – micnic 2013-05-13 09:29:25

你到底在问什么？你想达到什么目的？请更清楚地解释你到底在做什么。 – Greg 2013-05-13 09:29:49

<script type="text/javascript"> 
var jewels = new Array() 
var index 
var rand 

var scard = ["a1", "a2", "a3", "b1", "b2", "b3", "c1", "c2", "c3"]; 
var newarray = ["a1", "a2", "a3", "b1", "b2", "b3", "c1", "c2", "c3"]; 

drawBoard(); 



function drawBoard() { 


    var html = '<div class=Game_Background>' 

    for (var i = 0; i < 9; i++) { 

     rand = Math.floor(Math.random() * scard.length); 
     html += '<div class="' + scard[rand] + '" id="ship' + i + '" style="top:' + ((i * 12) + 135) + 'px; left:245px;" ></div>' 
     alert(newarray.indexOf(scard[rand])); 
     scard.splice(rand, 1); 
    } 
} 

</script>
