创作背景

个人在日常开发中，遇到了一个需求页面，页面交互较多，用到的事件也很丰富，特此记录，方便后续查找也方便有需要的开发者采用，本文涉及项目所用架构为开源的若依架构。

themleaf页面事件

onblur

离焦事件，页面输入框输入手机号离焦后触发ajax请求后台自动获取官网用户名并赋值在页面上，页面如图
在这里插入图片描述
页面代码

<div class="form-group">  <label class="col-sm-3 control-label"><span style="color: red;">*  </span>学员手机号：</label><div class="col-sm-8"><input id="phone" name="phone" class="form-control" type="text" onblur="getGwUserName();" placeholder="员工填写,必填"></div></div>

离焦事件触发方法getGwUserName()获取后台数据并返回重写在页面，getGwUserName()方法详情

//获取官网用户名function getGwUserName() {var phone = $("#phone").val().trim();if (checkNull(phone)) {$.ajax({type: "POST",url: prefix + "/getGwUserName",dataType: 'json',data: {phone: phone},success: function (result) {if (result.code == web_status.SUCCESS) {var data = result.data;$("#gwUserName").val(data.userName);//放置memberId用户后面从元数据获取官网订单信息$("#memberId").val(data.memberId);}else {$.modal.alertWarning("未获取到官网用户名，请手动输入");}}});}}

onclick

页面点击事件，这里点击添加在当前容器后拼接新的输入框内容
在这里插入图片描述
页面代码

<h3 style="float: left;padding-right: 100px;">官网抵扣商品信息</h3><button type="button" class="btn btn-w-m btn-primary" onclick="addgw();">添加</button><hr><div id="container"></div><h3>天猫成单信息</h3><hr>

点击事件触发方法addgw()往容器追加代码，可以多次点击添加内容，因此需要记录点击号clicknum用于动态化id，方便后续处理业务逻辑；addgw()方法内容

//点击添加按钮var clicknum = 0;function addgw() {var memberId = $("#memberId").val();if (checkNull(memberId)) {var html = '<div class="gwdetail">';html += '<div class="form-group"><label class="col-sm-3 control-label">订单号：</label><div class="col-sm-8"><input type="text" name="orderNo" id="orderNo'+clicknum+'" class="form-control" readonly onclick="getMetaOrders('+clicknum+');"/><input type="hidden" name="metaOrderId" id="metaOrderId'+clicknum+'"/></div></div>';html += '<div class="form-group"><label class="col-sm-3 control-label">抵扣商品：</label><div class="col-sm-8"><select name="deductionGoodsIds" class="form-control select2-multiple" multiple><option value="">请选择</option></select><button type="button" class="btn btn-w-m btn-primary" onclick="judgeRefund('+clicknum+');">关课/退款</button></div></div>';html += '<div class="form-group"><label class="col-sm-3 control-label">支付金额：</label><div class="col-sm-8"><input name="gwPaymentAmount" class="form-control" type="text"></div></div>\n';html += '<div class="form-group"><label class="col-sm-3 control-label">商品是否关课：</label><div class="col-sm-8"><select name="closeClass" class="form-control"><option value="">请选择</option><option value="0">否</option><option value="1">是</option></select></div></div>';html += '<div class="form-group"><label class="col-sm-3 control-label">抵扣商品是否有退款：</label><div class="col-sm-8"><select name="gwDrawback" class="form-control"><option value="">请选择</option><option value="0">否</option><option value="1">是</option></select></div></div>';html += '<div class="form-group"><label class="col-sm-3 control-label">抵扣金额：</label><div class="col-sm-8"><input name="deductionAmount" class="form-control" type="text"></div></div><div>---------------------------------------------------------------------</div></div>';$("#container").append(html);$("select[name='deductionGoodsIds']").select2();clicknum ++;}else {$.modal.alertWarning("请先填写学员手机号");}}

在addgw()添加页面属性中onclick方法getMetaOrders(‘+clicknum+’)主要是负责跳转到弹层列表页，选择相应的订单号点击确定之后再返回当前弹层页面;

//分页获取当前memberId下订单信息function getMetaOrders(num) {var memberId = $("#memberId").val();//var memberId = 34763975;$.modal.open("订单号", prefix + "/getMetaOrders?memberId="+memberId+"&clicknum="+num);}//官网抵扣商品是否关课/退款function judgeRefund(num) {var $1 = $('#orderNo'+num+'');var parent = $1.parent().parent().parent();var orderNo = $1.val();var goodsIds = parent.find("select[name='deductionGoodsIds']").val().toString();//console.log("orderno:"+orderNo);//console.log("goodsIds:"+goodsIds);if (checkNull(orderNo) && checkNull(goodsIds)) {$.ajax({type: "POST",url: prefix + "/checkOpenClassAndRefundStatus",dataType: 'json',data: {orderNo:orderNo,goodsIds: goodsIds},success: function (result) {if (result.code == web_status.SUCCESS) {var data = result.data;//console.log(data)//判断开关课状态var find = parent.find("select[name='closeClass']");//console.log(find);find.empty();var html = '<option value="">请选择</option>';if (data.openclass == 1) {//全部关课html += '<option value="0">否</option><option value="1" selected>是</option>';}else {//没有全关html += '<option value="0" selected>否</option><option value="1">是</option>';}find.append(html);var find2 = parent.find("select[name='gwDrawback']");find2.empty();var html2 = '<option value="">请选择</option>';if (data.refund == 1) {//全退html2 += '<option value="0">否</option><option value="1" selected>是</option>';}else {//没有全退html2 += '<option value="0" selected>否</option><option value="1">是</option>';}find2.append(html2);}}});}}

页面效果就是点击订单号弹层列表页，然后选中订单号点击确定

点击订单号弹层列表页，分页查询

弹层页面点击确定回传至父页面值的方法在弹层页面提交方法中

function submitHandler() {var id = $.table.selectColumns($.table._option.columns[1].field);if (id.length == 0) {$.modal.alertWarning("请至少选择一条记录");return;}var orderNo = $.table.selectColumns($.table._option.columns[2].field);$.modal.close();// 父页面的方法// activeWindow().selectUsers();// 父页面的变量var clicknum = $("#clicknum").val();console.log(id);console.log(orderNo);//console.log('#metaOrderId'+clicknum+'');activeWindow().$('#metaOrderId'+clicknum+'').val(id);activeWindow().$('#orderNo'+clicknum+'').val(orderNo);activeWindow().getMetaItem(clicknum);}

页面主要内容相关的就这些，其他的onclick或者onblur事件相似处理即可；
另外编辑页面在应对addgw()方法添加内容回显时采用了ajax返回html页面的处理方式

$(function () {getGwInfos();});//初始化加载官网抵扣商品信息function getGwInfos() {var recordId = $("#id").val();var memberId = $("#memberId").val();$.ajax({type: "POST",url: prefix + "/getGwInfos",dataType: 'html',data: {recordId: recordId,memberId:memberId},success: function (html) {$("#container").append(html);var array = $("#container").find("select[name='deductionGoodsIds']");array.each(function (i,item) {//console.log(item)$(item).select2();})//$(".gwdetail").find(".deductionGoodsIds").select2();}});}

具体的回显html页面代码如下

<div class="gwdetail" th:each="gw : ${gwInfos}"><input type="hidden" name="gwId" id="gwId" th:value="${gw.id}"/><div class="form-group"><label class="col-sm-3 control-label">订单号：</label><div class="col-sm-8"><input type="hidden" name="metaOrderId" th:id="metaOrderId+${gwStat.index}" th:value="${gw.metaOrderId}"/><input type="text" name="orderNo" th:id="orderNo+${gwStat.index}"  class="form-control" readonlyth:value="${gw.orderNo}" th:onclick="getMetaOrders([[${gwStat.index}]])"/></div></div><div class="form-group"><label class="col-sm-3 control-label">抵扣商品：</label><div class="col-sm-8"><select name="deductionGoodsIds" class="form-control select2-multiple" multiple><option value="">请选择</option><option th:each="item:${gw.items}" th:value="${item.goodsId}"th:selected="${gw.deductionGoodsIds?.contains(item.goodsId)}" th:text="${item.goodsName}"></option></select><button type="button" class="btn btn-w-m btn-primary" th:onclick="judgeRefund([[${gwStat.index}]])">关课/退款</button></div></div><div class="form-group"><label class="col-sm-3 control-label">支付金额：</label><div class="col-sm-8"><input id="gwPaymentAmount" name="gwPaymentAmount" class="form-control" type="text"th:value="${gw.paymentAmount}"></div></div><div class="form-group"><label class="col-sm-3 control-label">商品是否关课：</label><div class="col-sm-8"><select id="closeClass" name="closeClass" class="form-control"><option value="">请选择</option><option value="0" th:selected="${gw.closeClass == 0}">否</option><option value="1" th:selected="${gw.closeClass == 1}">是</option></select></div></div><div class="form-group"><label class="col-sm-3 control-label">抵扣商品是否有退款：</label><div class="col-sm-8"><select id="gwDrawback" name="gwDrawback" class="form-control"><option value="">请选择</option><option value="0" th:selected="${gw.drawback == 0}">否</option><option value="1" th:selected="${gw.drawback == 1}">是</option></select></div></div><div class="form-group"><label class="col-sm-3 control-label">抵扣金额：</label><div class="col-sm-8"><input id="deductionAmount" name="deductionAmount" class="form-control" type="text" th:value="${gw.deductionAmount}"></div></div><div>---------------------------------------------------------------------</div></div>

这里需要注意的是themleaf页面拼接动态id时的操作
在这里插入图片描述
这样的话涉及到themleaf复杂页面事件添加，各种事件交互的操作就完成了，重复的没有多写。

页面参数提交

由于addgw()方法会添加重复的属性名称，因此在提交时需要特殊处理，以list方式添加进提交参数json中提交，页面提交方法代码

function submitHandler() {var data = $.common.formToJSON('form-tmUpgradeOrderRecord-add');//var data = $('#form-tmUpgradeOrderRecord-add').serializeArray();var list= new Array();$("div[class='gwdetail']").each(function(i,item){var metaOrderId = $(item).find("input[name='metaOrderId']").val();var orderNo = $(item).find("input[name='orderNo']").val();var deductionGoodsIds = $(item).find("select[name='deductionGoodsIds']").val().toString();var gwPaymentAmount = $(item).find("input[name='gwPaymentAmount']").val();var closeClass = $(item).find("select[name='closeClass']").val();var gwDrawback = $(item).find("select[name='gwDrawback']").val();var deductionAmount = $(item).find("input[name='deductionAmount']").val();var detail = {"metaOrderId":metaOrderId,"orderNo":orderNo,"deductionGoodsIds":deductionGoodsIds,"paymentAmount":gwPaymentAmount,"closeClass":closeClass,"drawback":gwDrawback,"deductionAmount":deductionAmount};list.push(detail);});//data.push({"name":"gwlist","value":list});data["gwlist"]=list;data = JSON.stringify(data);//console.log(data);if ($.validate.form()) {$.operate.save2(prefix + "/add", data);}}// 获取form下所有的字段并转换为json对象formToJSON: function(formId) {var json = {};$.each($("#" + formId).serializeArray(), function(i, field) {json[field.name] = field.value;});return json;}

其中提交方法中调用的save2()ajax方法需要指定contentType: “application/json; charset=utf-8”，ajax默认的提交方式不支持json格式数据

后端接收参数方法中传参需要加入注解@RequestBody

这样整个过程就完整了，后续如果有需要但是博文没看明白的欢迎留言，一起进步。
