如何访问 vue.js 应用程序中的外部 json 文件对象

If your file looks like this:

[
{
"firstname": "toto",
"lastname": "titi"
},
{
"firstname": "toto2",
"lastname": "titi2"
},
]

You can do:

import json from './json/data.json';
// ....
json.forEach(x => { console.log(x.firstname, x.lastname); });

Just assign the import to a data property

<script>
import json from './json/data.json'
export default{
data(){
return{
myJson: json
}
}
}
</script>

then loop through the myJson property in your template using v-for

<template>
<div>
<div v-for="data in myJson">\{\{data}}</div>
</div>
</template>

NOTE

If the object you want to import is static i.e does not change then assigning it to a data property would make no sense as it does not need to be reactive.

Vue converts all the properties in the data option to getters/setters for the properties to be reactive. So it would be unnecessary and overhead for vue to setup getters/setters for data which is not going to change. See Reactivity in depth.

So you can create a custom option as follows:

<script>
import MY_JSON from './json/data.json'
export default{
//custom option named myJson
myJson: MY_JSON
}
</script>

then loop through the custom option in your template using $options:

<template>
<div>
<div v-for="data in $options.myJson">\{\{data}}</div>
</div>
</template>

Typescript projects (I have typescript in SFC vue components), need to set resolveJsonModule compiler option to true.

In tsconfig.json:

{
"compilerOptions": {
...
"resolveJsonModule": true,
...
},
...
}

Happy coding :)

I have recently started working on a project using Vue JS, JSON Schema. I am trying to access nested JSON Objects from a JSON Schema file in the Vue app. I tried the below code and now I can load different JSON objects inside different Vue template tags. In the script tag add the below code

import  {JsonObject1name, JsonObject2name} from 'your Json file path';

Now you can access JsonObject1,2 names in data section of export default part as below:

data: () => ({
  

schema: JsonObject1name,
schema1: JsonObject2name,
  

model: {}
}),

Now you can load the schema, schema1 data inside Vue template according to your requirement. See below code for example :

      <SchemaForm id="unique name representing your Json object1" class="form"  v-model="model" :schema="schema" :components="components">
</SchemaForm>


<SchemaForm id="unique name representing your Json object2" class="form" v-model="model" :schema="schema1" :components="components">
</SchemaForm>

SchemaForm is the local variable name for @formSchema/native library. I have implemented the data of different JSON objects through forms in different CSS tabs.

I hope this answer helps someone. I can help if there are any questions.
