java ,action
public void print(String rs){
PrintWriter out;
try {
HttpServletResponse response = ServletActionContext.getResponse();
response.setContentType("text/plain");
response.setCharacterEncoding("UTF-8");
out = response.getWriter();
// 获取分类数据
out.print(rs);
out.flush();

print("[{"proCode":"10241101","sellerId":"1001"},{"proCode":"10241101","sellerId":"1002"},{"proCode":"10241102","sellerId":"1001"}];")
后台拼成json格式，通过ajax接收返回结果，
$.ajax({
url : "utilAction.action",
type : "GET",
data : "service=showProduct",
success : function(result) {
var products = eval(result);// 转换为json对象
var datatable = "<table>";
for ( var i in products) {
datatable = datatable + "<tr><td>" + products[i].proCode + "</td><td>"
+ products[i].sellerId+"</td></tr>";
}
datatable = datatable + "</table>";
$("#mainDIV").html(datatable);
}
});
