八、picker用法 下拉框选择效果

<view class="uni-form-item">
	<view class="title">检测结果</view>
	<view class="input_box">
		<picker @change="examinationType" :range="examinationTypeArray" v-model="form.status">
			<label class="" style="color: gray;">{{ examinationTypeArrayType }}</label>
		</picker>
	</view>
</view>

export default {
	data() {
			return {
				form: {
					status: '',
					// 这里的status入参是选项数组列表012 （非选项文字）
				},
				// 检测结果 可选文本
				examinationTypeArray:['阴性','阳性','无效结果'],
				examinationTypeIndex:'',
				examinationTypeArrayType:'请输入',
			}
		},
	methods: {
		examinationType(e) {
			 this.examinationTypeIndex = e.target.value;
			 this.form.status=e.target.value;
			 this.examinationTypeArrayType=this.examinationTypeArray[this.examinationTypeIndex];
			 console.log(e);
			},
	}
}
