如何将VueJS数据密钥与空格配合使用 [英] How to use VueJS data key with space
问题描述
我正在使用每个表列都包含空格的现有数据库.作为VueJS api的结果,我得到了带有空格的数据密钥,如下所示:
I am working with existed Database which every table columns are containing white space. As result as VueJS api, I got the data key with white-space as below:
data = {
Course Trained:"82",
Course trained 2:null,
Delivery Channel:"IA2DC1",
End Date:"2017-05-06",
Full Name:"9",
ID:"1",
Intervention:"IA2",
Number of sessions:"5",
Start Date:"2017-05-02",
Training Orginisation:"2",
}
我的问题是,当我尝试使用'v-model'=>'Course Trained'时,整个页面都编译了一个错误.
My problem is when I tried to use 'v-model' => 'Course Trained', the whole page compiled an error.
如何在VueJS中处理带空格的内容?
How can I deal with this with-space in VueJS?
PS.我无法删除用于更改表列名称的空间.因为它与许多关系和第三方应用程序相关联.
PS. I cannot remove space to change the table column name. because it linked to many relationship and 3rd party application.
推荐答案
我认为使用带空格的数据变量不是一个好主意.它将使您的生活变得复杂.
I don't think it is a good idea using data variable with spaces. It will make you life complicated.
但是无论如何,您可以使用yourdata[key_name]
对其进行访问/v建模,如下所示:
But anyway, you can access/v-model it using yourdata[key_name]
like below:
app = new Vue({
el: "#app",
data: {
test: { //if not root
'test name': "Cat in Boots"
},
'test 1': 'Snow White' // if root
}
})
<script src="https://unpkg.com/vue@2.5.16/dist/vue.js"></script>
<div id="app">
<h2>{{test['test name']}}</h2>
<input v-model="test['test name']">
<h2>{{$data['test 1']}}</h2>
<input v-model="$data['test 1']">
</div>
Vue的作者说过:此将根据您所使用的功能范围在已编译的模板中进行更改.
As the author of Vue said: this will be changed in the compiled template depending on the function scope you are in.
因此请勿在模板中使用 this ,尤其是v-model
.
So don't use this in the template, especially v-model
.
app = new Vue({
el: "#app",
data: {
'test 1': 'Cat in Boots'
}
})
a {
color:red;
font-weight:bold;
}
<script src="https://unpkg.com/vue@2.5.16/dist/vue.js"></script>
<div id="app">
<h2>{{this['test 1']}}</h2>
<input v-model="this['test 1']"> <a>If using `this`, you will find v-model not working as expected</a>
</div>
