How To Get Selected Value Of A Dropdown Menu In Reactjs

Dropdown menus are a common user interface element used in web development to provide users with a list of options to select from. In React.js, handling the selected value from a dropdown menu is a task that many developers encounter. In this article, we will discuss how you can easily get the selected value of a dropdown menu in your React.js application.

The first step in getting the selected value of a dropdown menu in React.js is to set up your dropdown menu component. You can create a dropdown menu using the element along with elements for each option in the dropdown list. Make sure to assign a unique value to each element using the "value" attribute. This value will be used to identify the selected option.

Next, you need to define the state property in your component to store the selected value. Use the useState hook provided by React to create a state variable that will hold the selected value of the dropdown menu.

import React, { useState } from 'react';

function DropdownMenu() {
  const [selectedValue, setSelectedValue] = useState('');

  const handleSelectChange = (event) => {
    setSelectedValue(event.target.value);
  };

  return (
    
      Option 1
      Option 2
      Option 3
    
  );
}

export default DropdownMenu;

In the code snippet above, we have defined a functional component called DropdownMenu that maintains the selected value in the "selectedValue" state variable. The "handleSelectChange" function updates the selected value whenever the dropdown selection changes.

To access the selected value from the dropdown menu in your React.js application, you can simply use the "selectedValue" state variable wherever needed. For example, if you want to display the selected value in your component, you can render it like this:

return (
  <div>
    <h2>Selected Value: {selectedValue}</h2>
    
      Option 1
      Option 2
      Option 3
    
  </div>
);

By following these steps, you can easily get the selected value of a dropdown menu in your React.js application. Remember to set up the dropdown menu component, define the state variable to store the selected value, and handle the selection change event to update the selected value accordingly.
