getSqlSession sqlSession=new getSqlSession();
SqlSession session1=sqlSession.getSession();
CommColorMapper colorMapper=session1.getMapper(CommColorMapper.class);
ArrayList colorList=colorMapper.selectByAll();
//HttpSession session=request.getSession();
//System.out.println(colorList.get(1).getColorName());
//session.setAttribute(“colorList”, colorList);
JSONArray jsonArray = JSONArray.fromObject(colorList);
response.getWriter().print(jsonArray.toString());
接收
$("#comm_submit").click(function(){
$.ajax({
url:"commServlet.do",
type:"POST",
data:{
},
success:function(data){
alert(data);
var jsonObj = JSON.parse(data);//转换为json对象
for(var i=0;i<jsonObj.length;i++){
alert(jsonObj);
alert(jsonObj[i].colorid); //取json中的值
$("#comm_color_select").html(jsonObj[i].colorid);
}
}
结果：
[{“colorName”:"",“colorid”:1,“specificationid”:0},{“colorName”:"",“colorid”:2,“specificationid”:0},{“colorName”:"",“colorid”:3,“specificationid”:0},{“colorName”:"",“colorid”:4,“specificationid”:0},{“colorName”:"",“colorid”:5,“specificationid”:0},{“colorName”:"",“colorid”:6,“specificationid”:0},{“colorName”:"",“colorid”:7,“specificationid”:0}]
[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
1 2 3 4 5 6 7
由此可以得出，使用JSON进行传值时，在SERVLET中进行序列化，在AJAX中进行反序列化，然后进行取值。
