有下一个示例代码:
https://jsfiddle.net/JLLMNCHR/09qtwbL6/96/
HTML:
<div id="app">
<button type="button" v-on:click="displayVal()">Button1</button>
<autocomplete v-model="nombre" :items="[ 'Apple', 'Banana', 'Orange', 'Mango', 'Pear', 'Peach', 'Grape', 'Tangerine', 'Pineapple']" />
<button type="button" v-on:click="displayVal()">Button2</button>
</div>
<script type="text/x-template" id="autocomplete">
<div class="autocomplete">
<input type="text" @input="onChange" v-model="search" @keyup.down="onArrowDown" @keyup.up="onArrowUp" @keyup.enter="onEnter" />
<ul id="autocomplete-results" v-show="isOpen" class="autocomplete-results">
<li class="loading" v-if="isLoading">
Loading results...
</li>
<li v-else v-for="(result, i) in results" :key="i" @click="setResult(result)" class="autocomplete-result" :class="{ 'is-active': i === arrowCounter }">
{{ result }}
</li>
</ul>
</div>
</script>
CSS:
#app {
font-family: "Avenir", Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
color: #2c3e50;
margin-top: 60px;
}
.autocomplete {
position: relative;
width: 130px;
}
.autocomplete-results {
padding: 0;
margin: 0;
border: 1px solid #eeeeee;
height: 120px;
overflow: auto;
width: 100%;
}
.autocomplete-result {
list-style: none;
text-align: left;
padding: 4px 2px;
cursor: pointer;
}
.autocomplete-result.is-active,
.autocomplete-result:hover {
background-color: #4aae9b;
color: white;
}
我想问你我必须做些什么才能实现 displayVal 在自动完成中显示选定的值,或者用户在字段中写入的值,以防它不在列表中。
另外应该怎样做才能让 Button2 也显示出来?
呼啦一阵风
