“表格中没有数据”VueJS

我正在构建一个实时的Web应用程序。服务器在Node.js上运行,客户端在VueJS中编写。我编写了一个API来获取玩家信息。当我点击REST端点时,数据以表格的形式显示。虽然数据显示正确,但第一行显示“表中没有可用数据”。

这是我的代码

import urlMixin from "./../mixins/url.js";

export default {

    data() {
        return {
            playerData: "",
            errors:[]
        }
    },

    created: function(){
        this.getAllPlayers();
    },

    mixins: [urlMixin],

    methods: {
        getAllPlayers: function(){
            axios.get(`${this.url}/players`)
            .then(response =>{
                console.log(response.data.results);

                this.playerData = response.data.results;

                for(let i=0; i<this.playerData.length;i++){
                    this.playerData[i].image = 
                        "data:image/jpeg;base64," +
                        btoa(
                            new Uint8Array(this.playerData[i].image.data).reduce(
                                (data, byte) => data + String.fromCharCode(byte),
                                ""
                        )
                    );
                }

            })
            .catch(e => {
                this.errors.push(e);
            });
        }
    },

    mounted() {

        $(function() {
            $('#player-table').DataTable({
                dom: '<"ui center aligned"f><"ui segment"t><"right-aligned-panel"p>',
                language: {
                    info: "",
                    paginate: {
                        first: "first",
                        previous: "<i class='fa fa-chevron-left'></i>",
                        next: "<i class='fa fa-chevron-right'></i>",
                        last: "last"
                    }
                }
            });

        });

    }
}

我做错了什么?如何确保不显示“表格中没有数据”的文字?

您一直在使用jQuery,DataTables和Vue。虽然可以这样做,但这些库的生命周期功能必然会产生干扰。

vue社区有几个表库,例如https://github.com/matfish2/vue-tables-2

您正在使用this更改getAllPlayers方法中function的上下文。相反,使用es6箭头符号,如下所示:

getAllPlayers: () => {
    ....
        this.playerData = response.data.results;
    ....
}
