后台:
controller:
@RequestMapping(value = "/getProductByName", method= RequestMethod.POST) public void getProductByName(HttpServletRequest request, HttpServletResponse response) { String pName = request.getParameter("pName"); Product product = new Product(); product.setPName(pName); List<Product> list = productService.getProductByName(product); Object json = JSONArray.toJSON(list); String productInfo = json.toString(); try { DealResponse.dealResponse(response,productInfo); } catch (IOException e) { e.printStackTrace(); } }
DealResponse.dealResponse:
public static void dealResponse(HttpServletResponse response,String info) throws IOException { response.setContentType("application/x-www-form-urlencoded;charset=UTF-8"); PrintWriter out = response.getWriter(); out.println(info); }
前端js代码:
pro_name: function (val) { if( val == '' || val == null) { this.isActive = true; } else { this.isActive = false; let that = this; syn_request({ method: 'POST', url: '/getProductByName', headers: { 'Content-Type':'application/x-www-form-urlencoded' }, data: Qs.stringify({ pName: val }) }).then(response => { that.search_result = response.data; }).catch(err => { alert(err); }) } }
html页面:
<ul class="layui-nav search_result" @mouseleave="leave" :class="{result:isActive}" v-cloak > <li class="layui-nav-item" lay-unselect="" style="line-height:40px;width:100%" v-for="(index,item) in search_result" @click="getId(item.pId)"> <a >{{item.pName}}.{{index}}</a> </li> </ul>
后台响应的数据:
[{picPath: "C:\Users\yunsuowu\Desktop\2.jpg", pName: "测试1", planQuantity: 30, price: 13.3, parameter: "参数1:颜色||参数2:内存组合", …},
{picPath: "C:\Users\yunsuowu\Desktop\2.jpg", pName: "测试2", planQuantity: 41, price: 23.6, parameter: "参数1:颜色||参数2:内存组合", …}]
前端显示的数据.picPath: "C:\Users\yunsuowu\Desktop\2.jpg", pName: "测1", planQuantity: 30, price: 13.3, parameter: "参数1:颜色||参数2:内存组合", …
前端html页面在使用v-for遍历search_result时,无法通过item.pName获取pName的值,但是显示出来的是(.picPath: "C:\Users\yunsuowu\Desktop\2.jpg", pName: "测1", planQuantity: 30, price: 13.3, parameter: "参数1:颜色||参数2:内存组合", …),search_result定义成一个数组(search_result: []),因为时间原因只学了vue初级,想请教大佬这个问题怎么解决
讲了一大串 但是没明白您要问什么
函数的返回值用map,要返回map对象,不用response对象返回了
