React Selecting Option with Object as Attribute Value 

by vsasikalabe Updated: Jan 31, 2023

Using an object as the value for an option element in a select element can be useful when storing more information about each option than just a simple string value.

The option element can be used to represent each choice in the dropdown menu when used with a select element. You can set the value of the selected option using the value prop on the chosen element. The chosen element's value can be updated using an event handler when the onChange event is triggered whenever the user changes the selected choice. In web applications, select elements with option elements are frequently used to let users choose from a menu. The following examples demonstrate the use of select elements with option elements in React applications:

Form fields: For instance, you could use a select element to let customers choose their job title, preferred language, or home country.
Sorting and filtering data: For instance, you could use a select element to let users sort or filter a list of persons by name, birthdate, or a list of products by category.
Displaying dynamic data: You could use a select element to show a list of available products, a list of users, or a list of events, for instance.
Executing API calls: For instance, you could use a select element to let users select a country. Then, you could use the selected choice to execute an API call to retrieve information about that country.

Here is how you can include a React selecting the option with an object as an attribute value:

class Selector extends React.Component {
  contructor(props) {
    super(props);
    this.state = { obj: null }
    this.handleChange = this.handleChange.bind(this)
  }

  handleChange(e) {
    this.setState({obj: this.props.listOption[e.target.value].obj})
  }

  render() {
    <select onChange={handleChange}>
     {this.props.listOption.map((option, index) =>
       <option key={index} value={index}>
        {option.name}
       </option>
      )}
    </select>
  }
}

Instructions

Follow the steps carefully to get the output easily.

Install the Node.js and React on your IDE(preferable Visual Studio Code).
Create React Application using npx create-react-app foldername.
cd foldername.
Open the folder in IDE.
Copy the code using "copy" button above and paste it in App.js file(remove the earlier code from App.js).
import library.We have to add location,option name and return statement.(refer DEMO for additional codes)
Open the terminal from IDE.
npm start to run the file.
