//1.jquery ajax
<script type="text/javascript"> $(function(){ var basePath = $("#basePath").val(); //上架操作 $("#upAll").click(function(){ var chk_value =""; $('input[name="ckID"]:checked').each(function(){ chk_value += $(this).val()+","; }); if(chk_value == ""){ alert("请选择需要上架的项!!"); return; }else{ if(!confirm("确定上架吗?")){ return; } } var addNetworkId = $("#addNetworkId").val(); //alert("chk_value:" + chk_value); var dataString = {"actionName" : "up","addNetworkId" : addNetworkId, "chk_value" : chk_value}; var encoded = $.toJSON( dataString ); //alert("encoded:"+encoded); $.ajax({ type: "POST", url: basePath+"partsInfoKuAjaxAction", data: encoded, dateType:"json", success: function(data) { if(data.success == 1){ alert("商品上架成功!"); location.reload(true); //刷新,重新加载 }else if(data.success == 0){ alert("商品上架失败!"); } }, error: function(xhr) { //中间发生异常,具体查看xhr.responseText alert("error:" + xhr.responseText); } }); }); }); </script>
2.servlet处理,doPost方法
/**输入*/ String json = JsonUtils.readJSONString(request); log.info("删除Supply ID Json串: "+json); Map map = GsonUtils.parseData(json); String actionName = (String) map.get("actionName"); String chk_value = (String) map.get("chk_value"); String addNetworkId = (String) map.get("addNetworkId"); if(actionName.equals("up")){ String strUp[] = chk_value.split(","); boolean flag = false; Map mapPara; for (int i = 0; i < strUp.length; i++) { Integer id = Integer.parseInt(strUp[i]); mapPara = new HashMap(); mapPara.put("networkInfoId", Integer.valueOf(addNetworkId)); mapPara.put("updown", 0); mapPara.put("partsInfoId", id); flag = partnerMgrService.updateNetWorkInfoPartsInfo(mapPara); } String strJson; if(flag){ strJson = "{\"success\":\"1\"}"; }else{ strJson = "{\"success\":\"0\"}"; } /**输出*/ JsonUtils.writeJSONString(response, strJson); }
3.JsonUtils类
@Repository public class JsonUtils { public static String readJSONString(HttpServletRequest request) { StringBuffer json = new StringBuffer(); String line = null; try { BufferedReader reader = request.getReader(); while ((line = reader.readLine()) != null) { json.append(line); } } catch (Exception e) { //ln(e.toString()); } return json.toString(); } public static void writeJSONString(HttpServletResponse response,String strJson) throws IOException{ //String strJson = "{\"success\":\"1\"}"; response.setContentType("application/json; charset=utf-8"); PrintWriter out = response.getWriter(); out.print(strJson); out.flush(); out.close(); } }
4.form表单提交方式,post提交
String addNetworkId = request.getParameter("addNetworkId"); String actionName = request.getParameter("actionName"); if(actionName.equals("addOp")){ String[] checked = request.getParameterValues("ckID"); String chkValue; String retailPrice; Map map; if(checked != null){ for(int j=0; j<checked.length; j++){ chkValue = checked[j]; retailPrice = request.getParameter("retailPrice"+chkValue); map = new HashMap(); map.put("partsInfoId", chkValue); map.put("retailPrice", retailPrice); map.put("networkInfoId", Integer.valueOf(addNetworkId)); list.add(map); //添加到集合中来。 } } boolean flag = partnerMgrService.addNetWorkInfoPartsInfo(list); response.setContentType("text/html; charset=utf-8"); PrintWriter out = response.getWriter(); if (flag) { log.info("添加商品成功"); out.print("<script>" + "alert('添加商品成功');" + "window.location.href='" + Constants.ROOT + "/partner/network/partskumgr.jsp';" + "</script>"); } else { log.info("添加商品失败"); out.print("<script>alert('添加商品失败');" + "window.location.href='" + Constants.ROOT + "/partner/network/addpartsku.jsp';" + "</script>"); } }
