var html = '<div class=Game_Background>'

html += '<div class="' + jewels[rand] + '" id="ship' + i + '" style="top:' + ((i * 12) + 135) + 'px; left:245px;" ></div>'

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

这里a1,a2,a3,b1,b2,b3,c1,c2,c3是css类。我使用newarray是因为我拼接了所有的数组项。现在假设ship2 id的元素是b3,b3定位在newarray[ 5]。我如何检查这个(id 元素位于数组中的哪个索引数中)?
