如何在 vue.js 2 上使用两个值?
How to use two value on vue.js 2?
我这样尝试我的组件:
<script>
export default {
template: '\
<select class="form-control" v-on:change="search">\
<option v-for="option in options" v-bind:value="'+option.id+'|'+option.name+'">{{ option.name }}</option>\
</select>',
mounted() {
...
},
...
};
</script>
我用分隔符将它们分开|
所以,我将使用拆分来获取 ID 和名称
我这样试过,但存在错误:
Uncaught ReferenceError: option is not defined
我该如何解决?
这是你想要的:
new Vue({
el: '#demo',
data: {
selected: '',
options: [
{ text: 'One', value: 'A' },
{ text: 'Two', value: 'B' },
{ text: 'Three', value: 'C' }
]
}
})
<script src="https://vuejs.org/js/vue.min.js"></script>
<div id="demo">
<select v-model="selected">
<option v-for="option in options" v-bind:value="option.value+'|'+option.text">
{{ option.text }}
</option>
</select>
<span>Selected: {{ selected }}</span>
</div>
