RuoYi前后端不分离版选中导出Excel(前端)

RuoYi前后端不分离版选中导出Excel，封装公用方法

1、在ry-ui.js文件中添加下面的方法

exportSelectedIds: function (selectedIds) {
                table.set();
                var rows = $.common.isEmpty(table.options.uniqueId) ? $.table.selectFirstColumns() : $.table.selectColumns(table.options.uniqueId);
                console.log(rows, 'rows')
                if (rows.length == 0) {
                    $.modal.alertWarning("请至少选择一条记录");
                    return;
                }
                $.modal.confirm("确认要导出选中的" + rows.length + "条" + table.options.modalName + "吗？", function () {
                    var dataParam = { "ids": rows.join() }; // 选中的 ID
                    $.modal.loading("正在导出数据，请稍后...");
                    $.post(table.options.exportUrlIds, dataParam, function (result) {
                        if (result.code === web_status.SUCCESS) {
                            window.location.href = ctx + "common/download?fileName=" + encodeURI(result.msg) + "&delete=" + true;
                        } else if (result.code === web_status.WARNING) {
                            $.modal.alertWarning(result.msg);
                        } else {
                            $.modal.alertError(result.msg);
                        }
                        $.modal.closeLoading();
                    });
                });
            },

2、在需要导出的位置添加导出按钮html中

<a class="btn btn-warning" onclick="$.table.exportSelectedIds()" shiro:hasPermission="archive:info:export">
    <i class="fa fa-download"></i> 导出选中
</a>

var options = {
    exportUrl: prefix + "/export",
    exportUrlIds: prefix + "/export/selected",//选中导出接口路径
}
