datatable数据源不能被操作

用的datatable ajax获取数据源，行内的删除能执行成功 但是不管是delete还是update都不起作用，后台接口是通的，

```javascript
$(function () {

    return $('.datatable').DataTable({
        "language": {
            "decimal": "",
            "emptyTable": "表格无数据",
            "info": "本页显示 _START_ 到 _END_ 项 共 _TOTAL_ 项数据",
            "infoEmpty": "0 to 0 of 0",
            "infoFiltered": "(filtered from _MAX_ total entries)",
            "infoPostFix": "",
            "thousands": ",",
            "lengthMenu": "显示 _MENU_ 条/页",
            "loadingRecords": "加载中...",
            "processing": "请稍后",
            "search": "搜索:",
            "zeroRecords": "未找到相关记录",
            "paginate": {
                "first": "首页",
                "last": "尾页",
                "next": "下一页",
                "previous": "上一页"
            },
            "aria": {
                "sortAscending": ": 升序排列",
                "sortDescending": ": 降序排列"
            }
        },

        "ajax": {
            "url": "http://localhost:8080/SmartOA/user/getall",

            $("#switch").bootstrapSwitch({
                onText: "在线",      // 设置ON文本
                offText: "离线",    // 设置OFF文本
                onColor: "success",// 设置ON文本颜色(info/success/warning/danger/primary)

                        console.log("false");
                    }
                }
            });
        },
        "columnDefs": [{

这个你应该看下后台接口有没有真正删掉或者更新了这个数据

那你 刷新 页面后数据 是不是真的更新了 ？ 如果是 ，那就不是 后端的问题

• 关于该问题，我找了一篇非常好的博客，你可以看看是否有帮助，链接：常用的一些datatable使用操作

找到问题了，拿行数据加了引号，后面js 方法又加了引号，多加了一遍引号
