I am newbie to react, redux-saga, I have a dropdown in page Display
, when I select it move to respective component (eg. policy, score), In Component Pages, I have a button Add New
, on clicking it will navigate to a page as mentioned in link url , which is a page having cancel button, on cancelling it returns to the Display.js
but no dropdown selected,
I would like to keep the state articleMode
, when navigating to a page and returning back to same page,
articleMode returns to state -1 instead of selected component Policy
or Score
actions.js
export const updateArticleMode = data => {
console.log(data.body);
return {
type: CONSTANTS.UPDATE_ARTICLE_MODE,
data: data.body
};
};
queryReducer.js
import * as CONSTANTS from "../constants/constants";
const initialState = {
articleMode: ""
}
case CONSTANTS.UPDATE_ARTICLE_MODE: {
return {
...state,
articleMode: data.mode
};
}
export default queryReducer;
constants.js
export const UPDATE_ARTICLE_MODE = "UPDATE_ARTICLE_MODE";
Display.js

{ name: "Score", id: "Score" },
{ name: "Policy", id: "Policy" }
]
class Display extends React.PureComponent {

super(props);
this.state = {
articleMode: "-1"
};
}
componentWillMount = () => {
this.setState({ articleMode: this.props.queryData.articleMode || "-1" });
};
_getComponent = () => {
const { articleMode } = this.state;
if (articleMode === "Policy") {
return <DisplayPolicy></DisplayPolicy>;
}
if (articleMode === "Score") {
return <DisplayScore></DisplayScore>;
}
}
render() {
return (
<React.Fragment>
<select name="example"
className="simpleSearchSelect1"
value={this.state.articleMode}
onChange={event => {
this.setState({ articleMode: event.target.value });

{name}
</option>
);
})}
</select>
{this.state.articleMode === "-1"
