HAP——使用工具类导出Excel

这里我还只是能导出数据库中全部的数据，没有能够按条件查询数据然后导出，如果有需要可以参考导出EX

前端：

按钮：

     <div class="pull-left" id="toolbar-btn2" style="padding-bottom:10px;">
                    <span class="btn btn-primary" style="margin:0 2px;float: left; width: 70px"
                          data-bind="click:queryGrid" type="submit"><@spring.message "hap.query"/></span>
                    <span class="btn btn-default" style="margin:0 2px;float: left; width: 70px" data-bind="click:resetForm" type="button"><@spring.message "hap.reset"/></span>
                    <span class="btn btn-success" style="float:left;margin-right:5px;"
                          onclick="exportExcelFunction()" ><i class="fa fa-file-excel-o" style="margin-right:3px;"></i><@spring.message "导出Excel"/></span>
                </div>
                <script>kendo.bind($('#toolbar-btn2'), viewModel);</script>

js:

我用多条件没有能够成功，这里可以不用传参数，使用的时候可以去掉

function exportExcelFunction() {
        //1）执行exportMethod方法传递参数param
        var companyId=viewModel.model.get("companyId");
        var customerId=viewModel.model.get("customerId");
        var orderNumber=viewModel.model.get("orderNumber");
        var inventoryItemId=viewModel.model.get("inventoryItemId");
        var orderStatus =viewModel.model.get("orderStatus");
        // var inputParam = [
        //     {name:"companyId",value:companyId},
        //     {name:"customerId",value:"customerId"},
        //     {name:"orderNumber",value:"orderNumber"},
        //     {name:"inventoryItemId",value:"inventoryItemId"},
        //     {name:"orderStatus",value:"orderStatus"}
        //     ];
        var url = '${base.contextPath}/hap/om/order/headers/exportExcel?${_csrf.parameterName}=${_csrf.token}&companyId='+companyId+'&customerId='+customerId+'&orderNumber='+orderNumber+'&inventoryItemId'+inventoryItemId+'&orderStatus'+orderStatus;
        // $.ajax({
        //     type:'POST',
        //     data:JSON.stringify(inputParam),
        //     contentType :'application/json',
        //     dataType:'json',
        //     url :url,
        //     success :function(data) {
                window.location.href = url;
        // },
        //     error :function(e) {
        //         alert("error");
        //     }})
    }
