Show object's value text depending on select option










6














so I have this issue I am trying to solve, with React.



Let's say I have an object like so:



"options": 
"open":
"text": "Open (Risky)",
"description": "Filler text for open"
,

"wpa":
"text": "WPAWPA2PSK (TKIP / AES)",
"description": "Filler text for wpa"
,

"wpa2":
"text": "WPA2-PSK (AES) (Recommended)",
"description": "Filler text for wpa2"




And I have it setup that the object's value's "text" is used to populate option values in a select dropdown, like so:



const securityModeOptions = Object.values(securityMode.select.options);

securityModeOptions.map((mode, index) =>
<option key=index value=mode.text>
mode.text
</option>
)


What I would like to do is that whichever option value is selected, it's corresponding "description" is displayed in a div next to it, and the div changes based on whichever option is selected.



Thanks!

  • honestly not much, because it is supposed to be done in a "react" way (which I am brand new to), and the way I have gotten it to sorta work is very sloppy, so I am looking for some suggestions on a clean solution...

You can manage a state of the selected key, then grab the relevant entry from the options object via the key.



Something like this:






const options = 
open:
text: "Open (Risky)",
description: "Filler text for open"
,

wpa:
text: "WPAWPA2PSK (TKIP / AES)",
description: "Filler text for wpa"
,

wpa2:
text: "WPA2-PSK (AES) (Recommended)",
description: "Filler text for wpa2"

;

class App extends React.Component
state = selectedOptionKey: "" ;
onChange = ( target ) =>
this.setState( selectedOptionKey: target.value );
;
render()
const selectedOptionKey = this.state;
const description =
options[selectedOptionKey] && options[selectedOptionKey].description;
return (
<div>
<select onChange=this.onChange>
<option>Choose</option>
Object.entries(options).map(([key, value]) => (
<option value=key>value.text</option>
))
</select>
<div>description</div>
</div>
);


const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>

You could keep the key of the selected option in state and show the description of this selected option.



Example






const options = 
open:
text: "Open (Risky)",

wpa:
text: "WPAWPA2PSK (TKIP / AES)",
description: "Filler text for wpa"
,

wpa2:
text: "WPA2-PSK (AES) (Recommended)",
description: "Filler text for wpa2"

;

class App extends React.Component
state =
options,
selected: Object.keys(options)[0]
;

onChange = event =>
this.setState( selected: event.target.value );
;

render()
const options, selected = this.state;

return (
<div>
<select onChange=this.onChange>
Object.keys(options).map(key => (
<option key=key value=key>
options[key].text
</option>
))
</select>
<span>options[selected].description</span>
</div>
);



ReactDOM.render(<App />, document.getElementById("root"));
