1.后端代碼

２.前端html代碼

３.前端js代碼

$("#form-house-info").submit(function (e) {e.preventDefault();// 處理表單數據var data = {};$("#form-house-info").serializeArray().map(function(x) { data[x.name]=x.value });// 收集設置id信息var facility = [];$(":checked[name=facility]").each(function(index, x){facility[index] = $(x).val()});data.facility = facility;// 向后端發送請求$.ajax({url: "/api/v1.0/houses/info",type: "post",contentType: "application/json",data: JSON.stringify(data),dataType: "json",headers: {"X-CSRFToken": getCookie("csrf_token")},success: function (resp) {if (resp.errno == "4101") {// 用戶未登錄location.href = "/login.html";} else if (resp.errno == "0") {// 隱藏基本信息表單$("#form-house-info").hide();// 顯示圖片表單$("#form-house-image").show();// 設置圖片表單中的house_id$("#house-id").val(resp.data.house_id);} else {alert(resp.errmsg);}}})}); 創作挑戰賽新人創作獎勵來咯，堅持創作打卡瓜分現金大獎
