<!--html-->
<form class="layui-form layui-form-pane form-save" action=""><div class="layui-col-xs3 layui-col-sm3 layui-col-md3" style=""><textarea name="provider_order_id" class="layui-input"></textarea></div><button class="layui-btn layui-btn-primary layui-btn-md" lay-submit="search" lay-filter="search" id="search" data-type="search">查询</button><button class="layui-btn layui-btn-danger layui-btn-md" lay-submit="export" lay-filter="export" id="export" data-type="export">导出</button>
</form>

// 表单提交
form.on('submit(export)', function(data){var parames = new Array();parames.push({ name: 'data', value: JSON.stringify(data.field)});Post("<?php echo Url::toRoute('url');?>", parames);return false;
});// 跳转后端接口
function Post(URL, PARAMTERS) {//创建form表单var temp_form = document.createElement("form");temp_form.action = URL;//如需打开新窗口，form的target属性要设置为'_blank'temp_form.target = "_blank";temp_form.method = "post";temp_form.style.display = "none";//添加参数for (var item in PARAMTERS) {var opt = document.createElement("textarea");opt.name = PARAMTERS[item].name;opt.value = PARAMTERS[item].value;temp_form.appendChild(opt);}document.body.appendChild(temp_form);//提交数据temp_form.submit();
}

/*** 接受查询条件和查询* */
public function actionExport(){if (Yii::$app->request->isPost){$post = Yii::$app->request->post('data');$post = json_decode($post,true);$data1 = $this->getdata($post);foreach ($data1['data'] as $k => $d){$data[$k]['provider_order_id'] = $d['provider_order_id'];// ..}$this->xlsWriteExcel('orderNum,value','订单号,订单价格',$data);}
}/*** 插件导出* */function xlsWriteExcel($field,$header,$data,$fileName='自定义导出'){require_once Yii::getAlias('@vendor') .
