js删除数组中指定的属性

export function removeByValue(arr, attr, value) {// 1数组 2属性 3属性值
  var index = 0;
  for (var i in arr) {
    if (arr[i][attr] == value) {
      index = i;
      break;
    }
  }
  arr.splice(index, 1);
}
export default removeByValue;

import removeByValue from "./common/removeByValue/index.js";
Vue.prototype.$removeByValue = removeByValue;
//给它的原型添加一个名为$removeByValue的属性

this.$removeByValue(指定的数组, "数组中要删除的属性", "数组中要删除的属性值");
this.$removeByValue(this.columns12, "title", "研究院名称");
