js/vue如何实现函数(方法)当做参数传递

       //测试方法
       demo(){
          alert('我是测试')
       },
       haha(event){
        this.clickEnter(event,this.demo) //this.demo是方法,但是这里当做参数传递
     }  

//接收
        Vue.prototype.clickEnter = function(e,method){//e对应传递的第一个参数 ,method是你传递的方法
            let key = e.keyCode;
            if(key == 13){
                method()
            }
            
        }

apiName：'接口名称', 
params：'调取接口传的参数', 
refreshList：'点击确定按钮需要调取的列表方法刷新页面', 
isElse:'接口返回错误提示时是否需要调取列表方法刷新页面',
type：'notify通知框的类型', 
that

// 出库按钮  确认提示框
function popConfirm(apiName, params, refreshList, isElse, type, that) {
    console.log(that, 'reMethods')
    that.$confirm(
        window.vm.$i18n.t("tips.excutOp"),
        window.vm.$i18n.t("tips.tip"),
        {
            confirmButtonText: window.vm.$i18n.t("backTips.confirm"),
            cancelButtonText: window.vm.$i18n.t("backTips.cancel"),
            type: "warning",
        }
    ).then(() => {
        apiName(params).then((res) => {
            // 有返回状态值
            if (res.code == 0 && res.msg) {
                that.$notify({
                    title: res.msg,
                    type: 'success'
                });
                if (refreshList) {
                    refreshList()
                }
            } else if (res.code == 0 && res.msg == '') {
                that.$notify({
                    title: window.vm.$i18n.t("tips.issue"),
                    type: 'success'
                });
                if (refreshList) {
                    refreshList()
                } else {
                    if (isElse == true) {
                        refreshList()
                    }
                    that.$notify({
                        title: res.msg,
                        type: type
                    });
                }
            }

        }).catch((error) => {
            that.$notify({
                title: error.response.data.message,
                type: type
            });
            refreshList()
        });
    })
