问题描述 在组件中的Taro.chooseImage回调中自定义事件this.props.onUpdate(),父组件没有响应 复现步骤 子组件 Demo
chooseImage(){ let vm = this let {images, maxNum,name} = this.props Taro.chooseImage({ count: maxNum - images.length, sizeType: ['original', 'compressed'], sourceType: ['album', 'camera'], success: function (res) { vm.props.onUpdate({name:vm.props.name,value:res.tempFilePaths}) } }) }
父组件
updateForm(e){ console.log(e) } render(){ let {form} = this.state return ( <Demo maxNum={2} images={form.certImage} name='certImage' onUpdate={this.updateForm}></Demo> ) }
如果我在子组件回调中换一种写法,在父组件就可以正常调用并获得数据
test(images){ this.props.onUpdate({name:this.props.name,value:images}) } chooseImage(){ let vm = this let {images, maxNum,name} = this.props Taro.chooseImage({ count: maxNum - images.length, sizeType: ['original', 'compressed'], sourceType: ['album', 'camera'], success: function (res) { vm.test(res.tempFilePaths) } }) }
期望行为 当子组件选择完图片后父组件应该执行this.updateForm并返回参数
