官网的picker 不再介绍,今天主要介绍uni-app中对象数组的通过code取值;反显和设置

百度中有 mpvuePicker 的介绍,说是可以兼容安卓和ios,我使用的官网的picker也在安卓测试用也可以使用,APP 尚未发布,还不知道能不能使用,后续待补

先上代码
template中的代码

<view class="uni-common-mt bgWhite">
    <view class="uni-list">
        <view class="uni-list-cell">
            <view class="uni-list-cell-left">
                职业
            </view>
            <view class="uni-list-cell-db">
                <picker @change="pickerChange($event,'industry')" :value="data.industry" :range="industryList" range-key="value">
                    <view class="uni-input">{{industryList[data.industry].value}}</view>
                </picker>
            </view>
        </view>
        <view class="uni-list-cell">
            <view class="uni-list-cell-left">
                健康状况
            </view>
            <view class="uni-list-cell-db">
                <picker @change="pickerChange($event,'healthy')" :value="data.healthy" :range="healthyList" range-key="value">
                    <view class="uni-input">{{healthyList[data.healthy].value}}</view>
                </picker>
            </view>
        </view>
        </view>
</view>

javascript中的代码

<script>
    export default {
        components:{
            
        },
        data() {
            return {
                data:{
                    industry: 0,
                    healthy:0,
                },
                industryList: [
                    {name:"0",value:"国企"},
                    {name:"1",value:"私企"},
                    {name:"2",value:"合资"},
                ],
                healthyList: [
                    {name:"0",value:"没病"},
                    {name:"1",value:"有病"},
                ],
            }
        },
        computed:{
            
        },
        onLoad() {

        },
        methods: {
            tofamily(e) {
                console.log(e)  
                uni.navigateTo({
                    url: '../family/family',
                    success: res => {},
                    fail: () => {},
                    complete: () => {}
                });
            },
            pickerChange: function(e,val) {
                console.log('picker发送选择改变,携带值为', e.target.value)
                this.data[val]=e.target.value
            },
        }
    }
</script>

这段代码,多加一个当前model的参数,实现公共方法,可以使picker 通过数据中的code(name)来获取相对应的value,并显示的功能,而非必须使用外来组件 mpvuePicker 来完成官网应该完成的功能;
