服务端servlet代码片段:
/** * 处理请求 * @throws IOException */ private void requestManage(HttpServletRequest req,HttpServletResponse res) throws IOException{ //配置编码类型 res.setContentType("text/html;charset=UTF-8;pageEncoding=UTF-8"); //控制浏览器的编码行为 res.setCharacterEncoding("UTF-8");//目的是用于response.getWriter()输出的字符流的乱码问题,如果是response.getOutputStream()是不需要此种解决方案的;因为这句话的意思是为了将response对象中的数据以UTF-8解码后发向浏览器; res.setHeader("content-type","text/html;charset=UTF-8"); req.setCharacterEncoding("UTF-8"); String jason="{\"currentNumber\":10,\"pageNo\":1,\"pageSize\":10,\"rows\":[{\"email\":\"zhubj1@gmail.com\",\"firstname\":\"fname1\",\"id\":3,\"lastname\":\"lname1\",\"phone\":\"(000)000-0000\",\"valid\":true},{\"email\":\"name2@gmail.com\",\"firstname\":\"fname2\",\"id\":4,\"lastname\":\"lname2\",{\"email\":\"name3@gmail.com\",\"firstname\":\"fname3\",\"id\":5,\"lastname\":\"lname3\",{\"email\":\"name4@gmail.com\",\"firstname\":\"fname4\",\"id\":7,\"lastname\":\"lname4\",{\"email\":\"name5@gmail.com\",\"firstname\":\"fname5\",\"id\":8,\"lastname\":\"lname5\",{\"email\":\"name6@gmail.com\",\"firstname\":\"fname6\",\"id\":9,\"lastname\":\"lname6\",{\"email\":\"name7@gmail.com\",\"firstname\":\"fname7\",\"id\":10,\"lastname\":\"lname7\",{\"email\":\"name8@gmail.com\",\"firstname\":\"fname8\",\"id\":11,\"lastname\":\"lname8\",{\"email\":\"name9@gmail.com\",\"firstname\":\"fname9\",\"id\":12,\"lastname\":\"lname9\",{\"email\":\"name10@gmail.com\",\"firstname\":\"fname10\",\"id\":13,\"lastname\":\"lname10\",\"valid\":true}],\"total\":11,\"totalPages\":2}"; String callback=req.getParameter("callback");//得到回调函数名 System.out.println(callback); res.getWriter().write(callback+"("+jason+")");//封装成 回调函数名(data)形式 }
前端:
url="http://localhost:8888/study/test" 为跨域调用
<table id="dg1" title="用户管理" class="easyui-datagrid" style="width:100%;height:100%px" url="http://localhost:8888/study/test" toolbar="#toolbar" pagination="true" rownumbers="true" fitColumns="true" singleSelect="true"> <thead> <tr> <th field="firstname" width="50">姓</th> <th field="lastname" width="50">名</th> <th field="phone" width="50">电话</th> <th field="email" width="50">Email</th> <th field="classno" width="50">班级</th> </tr> </thead> </table>
js代码片段:
在jquery.easyui.min.js中增加一个跨域调用的js函数
$.ajax({type:opts.method,url:opts.url,data:_7ff,dataType:"jsonp",success:function(data){
