<body>
    <div id="app">
        <template>
            <span v-for="(item,index) in nameData">
                {{ index == nameData.length-1 && item.name || (item.name + ',') }}
            </span>
        </template>
    </div>

    <script>
        var Main = {
            data() {
                return {
                    nameData: [
                        {
                            name: '张三'
                        },
                        {
                            name: '李四'
                        },
                        {
                            name: '王五'
                        },
                        {
                            name: '赵六'
                        }
                    ]
                };
            }
        }
        var Ctor = Vue.extend(Main)
        new Ctor().$mount('#app')
    </script>
</body>

</html>

 方法二：

<span v-for="(item, index) in nameData" :key="index">
    {{ item.name }}
    <template v-if="index < nameData.length - 1">、/template>
</span>
