動態綁定title

原始碼如下：

            
        <div id="app-2">
            <span v-bind:title="message">
            Hover your mouse over me for a few seconds
            to see my dynamically bound title!
            </span>
        </div>
            
        

            
        var app2 = new Vue({
          el: '#app-2',
          data: {
            message: 'You loaded this page on ' + new Date().toLocaleString()
          }
        })
