我试图在我的选择输入中包含任何选项以设置为对象中的值。我试图为此目的使用v模型,但我不确定如何。到目前为止,我已经尝试过这样做。
<div class="select-wrapper">
<select required name="category" id="category" @change="(e) => $emit('input', e.target.value)">
<option value="" selected="selected">Category*</option>
<option value="attendee">Attendee</option>
<option value="distributor">Distributor</option>
<option value="sponsor">Sponsor</option>
<option value="media/analyst">Media/Analyst</option>
<option value="university">University</option>
<option value="other">Other</option>
</select>
</div>

需要一个道具来绑定选定的值,并将该道具传递给v-model
。例如
<template>
<div>
<pre>category = {{ category }}</pre>
<select required name="category" id="category" v-model="category">
<option value="">Category*</option>
<option value="attendee">Attendee</option>
<option value="distributor">Distributor</option>
<option value="sponsor">Sponsor</option>
<option value="media/analyst">Media/Analyst</option>
<option value="university">University</option>
<option value="nxp">NXP</option>
</select>
</div>
</template>
<script>
export default {
data() {
return {
category: null
};
}
};
</script>

您应该在组件中添加value
属性:
<div class="select-wrapper">
<select required name="category" id="category" @change="(e) => $emit('input', e.target.value)">
<option value="" selected="selected">Category*</option>
<option value="attendee">Attendee</option>
<option value="distributor">Distributor</option>
<option value="sponsor">Sponsor</option>
<option value="media/analyst">Media/Analyst</option>
<option value="university">University</option>
<option value="other">Other</option>
</select>
</div>
<script>
export default {
props:value
};
</script>
并将其用于父组件,如:
<my-select v-model="category"/>
...
<script>
export default {
data() {
return {
category: ''
};
}
};
</script>
