百思不得其答，为啥dojo未被引用进来

Question

我是一个前端开发小白，照书上抄了一段代码

<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<!--meta http-equiv="X-UA-Compatible" content="ie=edge"-->
<title>Account Preferences with Dijit</title>

<br> @import &quot;./dojoroot/dijit/themes/tundra/tundra.css&quot;;<br> @import &quot;./dojoroot/dojo/resources/dojo.css&quot;;<br>
data-dojo-config="async:true,parseOnLoad:true,isdebug:true" >

<script type="text/javascript" >

    dojo.require("dojo.parser");
    dojo.require("dijit.layout.ContentPane");
    dojo.require("dijit.layout.TabContainer");
    dojo.require("dijit.form.ValidationTextBox"); 
    dojo.require("dijit.form.DateTextBox");
    dojo.require("dijit.form.Button");

</script>

    明明引用了Dojo,为什么firebug 提示 dojo is not defined

Answer 1
