解决jquery乱码问题...

jQuery ajax乱码问题解决 一、测试环境 jQuery:1.3.2 tomcat:5.5.17 二、测试方法 1.使用get方式 服务器端代码： String name = new String(request.getParameter("name").getBytes("iso8859-1"),"utf-8"); 客户端js代码： $.ajax({url: "2.jsp",type: "get",data: {name:"中文"},success: function(response){ alert(response); }}); 结果：正确显示 $.ajax({url: "2.jsp",type: "get",data: "name=中文",success: function(response){ alert(response); }}); 结果：乱码 $.get("2.jsp", { name: "中文" },function(response){ alert(response); }); 结果：正确显示 $.get("2.jsp", "name=中文",function(response){ alert(response); }); 结果：乱码 2.post方式 服务器端代码： request.setCharacterEncoding("UTF-8"); String name = request.getParameter("name"); 客户端js代码： $.ajax({url: "3.jsp",type: "post",data: "method=testAjaxPost&name=中文",success: function(response){ alert(response); }}); 结果：正确显示 $.ajax({url: "3.jsp",type: "post",data: {name:"中文"},success: function(response){ alert(response); }}); 结果：正确显示 $.post("3.jsp", { name: "中文" },function(response){ alert(response); }); 结果：正确显示 $.post("3.jsp", "name=中文",function(response){ alert(response); }); 结果：正确显示 三、使用filter public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { HttpServletRequest req = (HttpServletRequest) request; if (req.getHeader("X-Requested-With") != null && req.getHeader("X-Requested-With").equalsIgnoreCase("XMLHttpRequest")) { request.setCharacterEncoding("utf-8"); } else { request.setCharacterEncoding("gbk"); } chain.doFilter(request, response); } jQuery在使用ajax的时候会在header中加入X-Requested-With，值为：XMLHttpRequest，filter中判断是jQuery的ajax请求时就把字符编码设为utf8，这样可以解决post提交中的中文乱码问题，不需要在代码中设置request.setCharacterEncoding("UTF-8"); 对于get方式的中文乱码问题，建议不使用get方式提交中文，统统改为post ^-^ 为了和prototype.js处理中文的方式一致，可以使用如下的方式，自定义header中的属性RequestType $.ajax({ url: "3.jsp", type: "post", data: {name:"中文"}, beforeSend: function(XMLHttpRequest){ XMLHttpRequest.setRequestHeader("RequestType", "ajax"); alert("开始"); }, success: function(data, textStatus){ alert(data); }, error: function(XMLHttpRequest, textStatus, errorThrown){ alert("错误：" + textStatus); }, complete: function(XMLHttpRequest, textStatus){ alert("完成：" + textStatus); } }); filter代码如下： public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { HttpServletRequest req = (HttpServletRequest) request; if (req.getHeader("RequestType") != null && req.getHeader("RequestType").equalsIgnoreCase("ajax"))) { request.setCharacterEncoding("utf-8"); } else { request.setCharacterEncoding("gbk"); } chain.doFilter(request, response); }
