vue.js如何生成S型拓扑图

    new Vue({
        el: '#app',
        data: {
        },
        mounted() {
            this.init()
        },
        methods: {
            init() {
                axios.get(site_url + "topo/").then(res => {
                    if (res.data.result){
                        $('#bktopo_demo .bktopo_box').bkTopology({
                            data: res.data.data, //配置数据源
                            lineType:[ //配置线条的类型
                                {type:'success',lineColor:'#46C37B'},
                                {type:'info',lineColor:'#4A9BFF'},
                                {type:'warning',lineColor:'#f0a63a'},

                            ]
                        });
                    }else{
                        this.$message.error('获取拓朴数据失败');
                    }
                },'json');
            }
        }
    })
