element el-select 支持拼音码和中文检索 检索的时候必须加属性 filterable

1.下载拼音码包导入进来

npm  install --save pinyin
import pinyin from 'pinyin'

2.修改element el-select 源码

import {
     
  escapeRegexpString    //这个方法是element el-select 检索方法 导入进来
} from 'element-ui/src/utils/util'

ElementUI.Option.methods.queryChange = function (query) {
     
  const reg = new RegExp(escapeRegexpString(query), 'i')
  const firstLetter = pinyin(this.currentLabel, {
     
    style: pinyin.STYLE_FIRST_LETTER
  }).join('')
  this.visible = reg.test(this.currentLabel) || reg.test(firstLetter) || this.created
  if (!this.visible) {
     
    this.select.filteredOptionsCount--
  }
}
Vue.use(ElementUI)
