用正则表达式验证就行了,可以用^[\u4e00-\u9fa5]+$来匹配汉字,如:
<input type="text" onchange="javascript:if(!/^[\u4e00-\u9fa5]+$/gi.test(this.value))alert('含有非汉字字符');">
这是前台添加用户后台验证啊？？
后台加这么一句，通过request获取
try {
request.setCharacterEncoding("utf-8");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
前台加这么一句，设置语言
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8" %>
求各位欸大神给出具体代码
js代码如下：
function testChineseName(name)
{
if(/^[\u0391-\uFFE5]+$/.test(name))
{
alert("都是汉字");
}
else
{
alert("不是汉字");
}
}
