vue-cli定义全局过滤器

// 获取“-”之前的字符串过滤器
let getHGbeforeStr = value =>{
  if(!value) return ''
  if(value.search("-") !== -1){
    return value.split("-").shift()
  } else {
    return ''
  }
}
// 获取“-”之后的字符串过滤器，数据示例 xxx-xxx
let getHGlaterStr = value =>{
  if(!value) return ''
  if(value.search("-") !== -1){
    return value.split("-").pop()
  } else {
    return value
  }
}
export {
  getHGbeforeStr,
  getHGlaterStr
}

main.js引入

import * as filters from '@/assets/js/filter'
Object.keys(filters).forEach(key => {
  Vue.filter(key, filters[key])
})
