var tipTemplate = {
          template: '<transition name="fade">\
                        <p v-if="tip" class="vertical-horizontal-center">\
                            <img src="../image/no-log.png">\
                            <h2>暂无记录</h2>\
                            <p class="aui-btn aui-btn-info">重新加载</p>\
                        </p>\
                    </transition>',
           props: ['tip']
        }
<my-tip tip="tip"></my-tip>

建议再看一下文档,组件的作用域那一块

过去多啦不再A梦

props: ['tip']应该写在var tipTemplate={}中,而不是写在 new Vue({})中,组件的作用域弄错了

楼上的解答有问题,组件要动态属性绑定:

<my-tip :tip="tip"></my-tip>

整体如下:

    <body>
        <p id="app">
            <button v-on:click="tip = !tip">Toggle</button>
            <my-tip :tip="tip"></my-tip>
        </p>
    </body>
    <script type="text/javascript" src="../script/vue.js"></script>
    <script type="text/javascript">
        Vue.component('simple-counter', {
          template: '<transition name="fade">\
                        <p v-if="tip" class="vertical-horizontal-center">\
                            <img src="../image/no-log.png">\
                            <h2>暂无记录</h2>\
                            <p class="aui-btn aui-btn-info">重新加载</p>\
                        </p>\
                    </transition>',
          props: ['tip']
        })
        
        new Vue({
          el: '#app',
          data: {
              tip: false
          },
          created: function() {}
        })
    </script>

在子组件上加一个v-if="tip"
