测试在网页上<script>在各个地方的执行顺序. 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>无标题页</title>
    <script type = "text/javascript">
        alert("head部分的script");
    </script>
</head>
    <script type = "text/javascript">
        alert("body与head之间的script");
    
    </script>
<body onload = "alert('body的onload上的script')">
    <script type = "text/javascript">
        alert("body内的script");
    </script>
</body>
    <script type = "text/javascript">
        alert("body下的script");
    </script>
</html>

　　以上执行顺序结果是:head->body&head之间->body内->body外->body的onload ..
