Spread the love

Sometimes, we want to allow users to select the same file more than once in a React component.

In this article, we’ll look at how to allow users to select the same file more than once in a React component.

Allow File Input to Select the Same File in React Component

We can let a file input select the same file in a React component if we set it to null after we click on it.

For instance, we can write:

<input
  id="upload"
  ref="upload"
  type="file"
  accept="image/*"
  onChange={(event)=> {
    this.readFile(event)
  }}
  onClick={(event)=> {
    event.target.value = null
  }}
/>

We have the onChange prop that takes a function to read a file.

In the onClick prop, we set the file input value to null .

Passing a Number to a Component

We can pass a number to a component by passing in a number in curly brackets.

For instance, we can write:

Rectangle width={10} height={20} />

Conclusion

We can let a file input select the same file in a React component if we set it to null after we click on it.
