单击按钮时使用两个redux操作

[英]Using two redux actions when clicking a button

Sounds like something simple enough, but redux is just so darn confusing. 听起来很简单,但redux只是让人感到困惑。

As it is now, I have a list of buttons created based off of a reducer object, and when I click one of them, I make a get request which return me an object, which I then render accordingly. 就像现在一样,我有一个基于reducer对象创建的按钮列表,当我单击其中一个时,我发出一个get请求,它返回一个对象,然后我相应地进行渲染。

What I would like to add is the name of the button clicked and use it as a title to what is created from the get request. 我想添加的是点击按钮的名称,并将其用作从get请求创建的内容的标题。

Here is my current code: 这是我目前的代码:

//containers/module-buttons.js
//where the buttons are creared and bound to an action
//fetchLogs(moduleUrl) is with the get request I am making
class ModuleButtons extends Component{
    createListItems(){
        return this.props.modules.map((module)=>{
            return (
                <ListGroupItem bsStyle="warning" key ={module.id}
                               onClick={()=>this.props.fetchLogs(module.url)}>
                                {module.name}</ListGroupItem>
            );
        });
    }

    render(){
        return (
            <ListGroup>
                {this.createListItems()}
            </ListGroup>
        );
    }
}

function mapStateToProps(state){
    return {
        modules: state.modules

    };
}

function matchDispatchToProps(dispatch){
    return bindActionCreators({fetchLogs: fetchLogs}, dispatch);
}

//containers/module-log.js
//whenever a button is clicked, the json object from the get request is rendered here
//what I want to do it in the <h3> tags put the name of the button previously clicked.
class ModuleLog extends Component{

    render(){
        if (!this.props.module){
            return <Panel><h5>Please select a module</h5></Panel>;
        }
        else{
            const renderData = Object.keys(this.props.module)
            .map((mainKey, key )=> <Log mainKey={mainKey}
                      innerObject={this.props.module[mainKey]} key={key} />);
            return (
                <div>
                    <h3>[insert module name here]</h3>
                    <ul>{renderData}</ul>
                </div>
            );
        }
    }
}

function mapStateToProps(state){
    return {
      module: state.moduleLog
    };
}

export default connect(mapStateToProps)(ModuleLog);

// actions/actions.js
export const moduleClicked = (module) =>{
    return {
        type: "MODULE_CLICKED",
        payload: module
    }
}

export function fetchLogs(moduleUrl){
    console.log(moduleUrl);
    const request = axios.get(moduleUrl);
    return (dispatch) => {
        request.then(({data}) =>{
            dispatch({type: 'FETCH_MODULES', payload: data});
        });
    };
}

Edit: added the code in the actions.js file. 编辑:在actions.js文件中添加了代码。

Why not just add an extra argument to fetchLogs and then dispatch another action? 为什么不在fetchLogs中添加额外的参数然后再发送另一个动作呢?

<ListGroupItem 
  bsStyle="warning" key ={module.id}
  onClick={()=>this.props.fetchLogs(module.url, module.name)}>
    {module.name}
</ListGroupItem>

And hence: 因此:

//actions.js

export function fetchLogs(moduleUrl, moduleName){
    console.log(moduleUrl);
    const request = axios.get(moduleUrl);
    return (dispatch) => {
        request.then(({data}) =>{
            dispatch({type: 'FETCH_MODULES', payload: data});
            dispatch({type: 'MODULE_CLICKED', payload: moduleName});
        });
    };
}
