OnChange event using React JS for drop down

🎉 Solving the onChange Event Issue with React JS for Dropdown 🎉

So you're facing an issue with the onChange event for a dropdown in React JS? Don't worry, we've got your back! In this blog post, we're going to address this common problem and provide easy solutions so you can get your dropdown working seamlessly. Let's dive right in! 💪

Understanding the Problem 🤔

You might have noticed that the onChange event is not firing as expected when a selection is made in the dropdown. In the given example code, the onChange event is placed on each option inside the <select> element. However, this approach does not work because the onChange event should be placed on the <select> element itself.

The Solution 🚀

To fix the issue and make the onChange event work for a dropdown in React JS, follow these steps:

1. Remove the onChange prop from each <option> element and place it on the <select> element.

   <select id="lang" onChange={this.change}>

2. Update the change function implementation to access the selected value from the <select> element instead of querying it from the DOM directly.

   change: function(event){ return event.target.value; },

3. In the <p> tag that displays the selected value, update the value prop to call the change function instead of accessing its value directly.

   <p value={this.change()}></p>

That's it! Your onChange event for the dropdown should now be working as expected. 🎉

Example Code 💻

Here's the updated code with the necessary changes highlighted:

var MySelect = React.createClass({
   change: function(event){
       return event.target.value;
   },
   render: function(){
      return(
         <div>
             <select id="lang" onChange={this.change}>
                <option value="select">Select</option>
                <option value="Java">Java</option>
                <option value="C++">C++</option>
             </select>
             <p value={this.change()}></p>
         </div>
      );
   }
});

React.render(<MySelect />, document.body);
