Vue 中全局过滤器的使用

import filter from './filter/filter'

// 全局过滤器
Object.keys(filter).forEach(key => {
  Vue.filter(key, filter[key]);
});

let optionKV = (list, key) => {
  if (!list || !key) {
    return "";
  } else {
    let result = "";
    for (let i = 0; i < list.length; i++) {
      if (key === list[i]["key"]) {
        result = list[i]["value"];
      }
    }
    return result;
  }
};

export default {
  optionKV
}

<td>{{CHARGE | optionKV("C")}}</td>

CHARGE = [
  {key: "C", value: "收费"},
  {key: "F", value: "免费"}
];
