文本字段有点像这样:
<v-text-field v-model="input" placeholder="(0 - 200)">
</v-text-field>
Vue.js
data
包含:export default {
data () {
return {
input: '',
proposed: 0
}
}
}
我希望占位符显示如下内容:
placeholder="Proposed quantity: 2 (0 - 200)"
尝试通过以下方式设置
proposed
变量:a) placeholder="Proposed quantity: {proposed} (0 - 200)"
b) placeholder="Proposed quantity: `${proposed}` (0 - 200)"
c) placeholder="Proposed quantity: " + proposed + " (0 - 200)"
都没有。
还有其他想法和建议吗?
最佳答案
您必须使用placeholder
或:
将v-bind:placeholder ...
绑定(bind)到数据对象,例如:
:placeholder="'Proposed quantity: '+proposed+ ' (0 - 200)'"
要么
v-bind:placeholder="'Proposed quantity: '+proposed+ ' (0 - 200)'"
