如何将参数传递给mapStateToProps()? 例如: const mapStateToProps = (state, dimenType: string) = { var jsonVariable = {} for(var i=1; i = 3; i++) { jsonVariable[dimenType + i] = dimenType + i } console.log(jsonVariable) return {
例如:
const mapStateToProps = (state, dimenType: string) => { var jsonVariable = {} for(var i=1; i <= 3; i++) { jsonVariable[dimenType + i] = dimenType + i } console.log(jsonVariable) return { width1: state.get('width').get('width1').toString(), width2: state.get('width').get('width2').toString(), width3: state.get('width').get('width3').toString() } }
这是我不确定的一点:
Width = connect( mapStateToProps(/*redux store goes here somehow*/, 'thickness'), mapDispatchToProps )(Width)
我希望redux存储仍然传递到mapStateToProps,但也传递“厚度”.我如何在connect()函数中执行此操作?
connect的第二个参数是ownProps,它是传递给Component的props.所以在你的情况下你可以像这样使用它:const mapStateToProps = (state, ownProps) => { let jsonVariable = {} for(var i=1; i <= 3; i++) { jsonVariable[dimenType + i] = ownProps.dimenType + i } console.log(jsonVariable) return { width1: state.get('width').get('width1').toString(), width2: state.get('width').get('width2').toString(), width3: state.get('width').get('width3').toString() } }
我假设您正在创建这样的组件:<宽度厚度= {10} />
