主要是選擇值問(wèn)題

上代碼：

<el-select v-model="selectCountry" placeholder="請(qǐng)選擇" @change="selectValue()">
                  <el-option
                    v-for="item in countryData"
                    :key="item.abbreviation"
                    :label="item.country"
                    :value="item.country">
                  </el-option>
                </el-select>

1.通過(guò)el-select的change事件會(huì)在選中值變化時(shí)觸發(fā)，而選擇的值存放在 v-model="selectCountry"中
2.在methods中，change的綁定事件進(jìn)行獲取

selectValue() {
      console.log(this.selectCountry)//打印輸出的是  :value="item.country"的值
    },

3.這是我的數(shù)據(jù)

countryData:[
        {"country":"Afghanistan","abbreviation":"AFG"},
        {"country":"Albania","abbreviation":"ALB"},
        {"country":"Algeria","abbreviation":"DZA"},
        {"country":"All Qatar","abbreviation":"QAT"},
        {"country":"angola","abbreviation":"AGO"},
    ]
