效果

<uni-forms-item label="任务类型" label-width="80px" name="height">
	<uni-data-picker :localdata="cateList" v-model="form.listCategory" :map=" {text:'catName',value:'catName'}"popup-title="请选择任务类别" @change="onchange" @nodeclick="onnodeclick">
	</uni-data-picker>
</uni-forms-item>

数据绑定：localdata
转换为组件格式数据：:map="{text:'catName',value:'catName'}"  这块根据你自己后端获取到的数据格式绑定

onnodeclick(e) {
	console.log(e);
},


onchange(e) {
	console.log('onchange:', e);
}
