|
||
这意味着<code>v-el:my-element</code> 将写成这样：<code>ref="myElement"</code>，<code>v-ref:my-component</code>将写成 <code>ref="myComponent"</code>。</p> <h2 id="v-for"><a href="#v-for" class="header-anchor">#</a> <code>v-for</code></h2> <p>Vue1.x遍历对象的参数顺序是 <code>(key, value)</code>，Vue2.x更新成<code>(value, key)</code>，跟常见的对象迭代器 (例如 lodash) 保持一致。<br>
|
||
Vue1.x使用v-for时，在迭代项中可以使用参数顺序<code>$index</code>，而且默认使用<code>track-by="$index"</code>。Vue2.x中<code>v-for</code>移除了隐式的<code>$index</code>，在循环的子项加上<code>:key="index"</code>。</p></div> <footer class="page-edit"><!----> <div class="last-updated"><span class="prefix">上次编辑时间:</span> <span class="time">11/27/2020, 3:38:53 AM</span></div></footer> <!----> </main></div><div class="global-ui"><!----></div></div>
