Vue引入js变量，常量及文件

1，变量引用
外部js:

var s = "变量数据";
export default{
customData:function () {
return s;
}
}

vue实例文件

import SM from "../../static/js/networkRequest"
export default {
data () {
return{
newData:SM.customData()
}
}
} 

2，方法调用
外部js:

function test(){
console.log("tttttttttttttttttttt::::")
}
export {
test
}

vue实例文件

import { test} from "../../static/js/mathUtils"
created(){
this.test2();
}，
methods: {
test2(){
test()
}
}

3，变量引用
外部js:

const S="dd"
export {
accMul,
S
}

vue实例文件

import { accMul,S } from "../../static/js/mathUtils"
export default {
data () {
return{
str:S
}
}，
created(){
console.log("=====================::::" +accMul(2,4))
console.log("=====================::::" +this.str)
}
}
