<title>让一个文本框只能输入汉字的方法</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
</head>
<body>
<input onkeyup="value=value.replace(/[^\u4E00-\u9FA5]/g,'')" onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\u4E00-\u9FA5]/g,''))">试着在文本框里分别输入汉字和英文字符试试？
