我试图通过在字符串中使用 \n 在作为 Vuetify 对话框文本的字符串中插入一个新行。但它不起作用。
这是调用 Vuetify 对话框的函数的代码
handleDialog()
{
this.dialogHeading = "Clearing all component data"
this.dialogText = "Do you really want to clear all the component data?\nThis will clear the components except the pressure and composition basis!"
this.dialogBtn1 = "Cancel"
this.dialogBtn2 = "Yes"
this.isDialog = true

这是显示 Vuetify 对话框的代码
<v-layout row wrap >
<v-flex class="text-xs-center">
<v-dialog v-model="isDialog" persistent max-width=400>
<v-card>
<v-card-title class=" error title white--text
darken-2 font-weight-bold">{{dialogHeading}}
</v-card- title>
<v-card-text>{{dialogText}}</v-card-text>
<v-card-text v-if="dialogText2">{{dialogText2}}
</v-card-text>
<v-card-actions >
<v-btn v-if="dialogBtn1" flat class=

我试过使用 '\n' 。
我需要下一行的第二句话
任何帮助,将不胜感激。先感谢您
您应该使用<br/>tag 而不是\n为了转到下一行并使用v-html指令来呈现该字符串:
this.dialogText = "Do you really want to clear all the component data?<br/>This will clear the components except the pressure and composition basis!"

实现此目的的一种方法是将每一行包装在块级元素中,例如<div>模板内的a 。原始字符串可以在换行符上拆分并相应地迭代:
new Vue({
el: '#app',
vuetify: new Vuetify(),
data () {
return {
dialogText: 'First line\nSecond line'
}
}

这保留了使用v-html.
