我有一个包含以下数据的组件,它是一个简单的数组:
data() {
return {
permissions: [
{ id: '1' , name: 'create'},
{ id: '2' , name: 'edit'},
{ id: '3' , name: 'delete'}
]
}
}
此外,我还创建了以下使用此数组的计算属性,并返回对象数组:
computed: {
getFormPermissionId(){
var permission = this.permissions
for(let i = 0;i < permission.length; i++ ) {
return permission[i].id
}
}
}
我想要没有v-for的模板中的此输出,如下所示:
1
2
3
我不知道如何在模板中应用。这是我的代码https://codepen.io/thon0209/pen/vPybWw
谢谢:)
var app = new Vue({
el: '#app',
data() {
return{
permissions: [
{
id:1,
name:'create'
},
{
id:2,
name:'edit'
},
{
id:3,
name:'delete'
}
]
}
},
computed: {
getFormPermissionId(){
var permission = this.permissions
for(let i = 0;i < permission.length; i++ ) {
return permission[i].id
}
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
{{getFormPermissionId}}
</div>

您正在使用.navbar {
position: fixed;
top: 0;
left: 0;
right: 0;
height: 30px;
background: rgba(255, 255, 255, 0.8);
}
,它将停止功能的进一步执行。您可以创建一个变量,并在内部循环中将值连接到该变量,最后return
将其连接。
return
var app = new Vue({el: '#app',data() {return
{permissions: [
{id:1,name:'create'},
{id:2,name:'edit'},
{id:3,name:'delete'}]
}
},
computed: {
getFormPermissionId(){
var permission = this.permissions
let result = '';
for(let i = 0;i < permission.length; i++ ) {
result += permission[i] + '<br>'
}
return result;
}
}
})

您可以创建字符串并且可以执行相同的操作
Eval
完整示例
IsTerm/Eval
var app = new Vue({
el: '#app',
data() {
return {
permissions: [{
id: 1,
name: 'create'
},
{
id: 2,
name: 'edit'
},
{
id: 3,
name: 'delete'
}
]
}
},
computed: {
getFormPermissionId() {
var permission = this.permissions;
//Creating String
str = "";
for (let i = 0; i < permission.length; i++) {
str += permission[i].id + "\n";
}
return str;
}
}
})

这是您可以做的:
<div id="app">
<div v-for="(item, index) in permissions" :key="index">
{{item.id}}
<br/>
</div>
</div>
您只需删除计算出的值即可。
