选项
eleId 分页容器，仅支持ID，默认为： 'gbpaging' total: 总记录数 paramName: 分页参数名 || 'p' curPage: 当前页码 size: 每页记录数 || 10 prevText: 上一页文案 || '上一页'，值为 false 不显示 nextText: '下一页文案 || '下一页' 值为 false 不显示 pageInfo: 分页信息，{{currentPage}}当前页码，{{totalPages}}总页数 || 当前第{{currentPage}}页/共{{totalPages}}页，值为 false 不显示 eventType: 事件方式，'click' || 'link' goUrl： 链接URL，'?type=1&name=2&{{n}}' || ''，{{n}}为分页参数名+值，如：'p=1'
