1. Reason analysis:
The js code is not placed in the Ext.onReady function, and the deep-seated reason has not been understood. . .
2. Error code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gbk">

<link rel="stylesheet" type="text/css" href="../resources/css/ext-all.css" />
<script type="text/javascript" src="../ext-all.js"></script>
<script type="text/javascript" src="Chinese.js"></script>
<script type="text/javascript">
var form = new Ext.form.FormPanel({

defaultType : 'textfield',
buttonAlign : 'center',

buttons : [{

});
form.render("form");
</script>
