举个栗子:

<a v-on:click="Delete(item.JD_WarehousePriceID)">删除</a>

<script>
        var table1Vue = new Vue({
            el: '#table1',
            data: {
                items: []
            }, methods: {
                 Delete: function (id) {
                    if (confirm("确定删除,ID: " + id + " 的数据?") == true) {
                        if (id) {
                            $.ajax({
                                url: "/JD_ReturnFee/DELETE",
                                type: "post",
                                data: { "ID": id },
                                dataType: "json",
                                success: function (data) {
                                    alert(data.message);
                                    if (data.code == 200) {
                                      table1Vue.Bind();//在methods里面调用函数
                                    }
                                }
                            });
                        }
                    }
                }, Bind: function () {
                    var index = 1;//页码
                    var size = 500;//每页条数
                    var Tag = $("#selTag").val();
                    var Project = $("#selProject").val();
                    $.ajax({
                        data: {
                            "Tag": Tag,
                            "Project": Project,
                            "pageIndex": index,
                            "pageSize": size,
                        },
                        url: "/JD_ReturnFee/DataTablePage",
                        dataType: "json",
                        success: function (request) {
                            table1Vue.items = request.data;
                            PagerMaker(request.total, request.allPage, pageIndex, size);
                        },
                    });
                }
            }, mounted: function () {
                this.$options.methods.Bind();//看这里,在mounted里调用methods里的函数Bind
            },
        });
    </script>

关键是这个:

this.$options.methods.Bind();                                                                                                        

在其他地方调用mounted里的函数:

①把new出来的Vue,挂载给一个对象, 如: var table1Vue = new Vue ... , 挂载给 table1Vue

②在其他的 Vue里面调用函数,如: table1Vue.Bind();//在methods里面调用函数
