为什么不显示文字？
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>使用数组</title>
<script style="text/javascript">
var myarr=new Array();
myarr[0]="小红";
myarr[2]="小亮";
myarr[3]="小川";
document.write("第二人的姓名是:"+myarr[1]="小" );
</script>
</head>
<body>
</body>
</html>
