The functionality of Flatbutton(Input handler) appears to be malfunctioning

I am having trouble with the file uploader from Material-UI. It doesn't seem to be working properly when I try to select a file. Does anyone have any suggestions on how to handle the input from the file selector?

<FlatButton
            icon={<i className="material-icons">attachment</i>}
            onclick={e => this._handleChange(e)}
            onchange={e => this._openFileDialog(e)}
          >
            <input type="file" style={styles.uploadInput} />
          </FlatButton>

Answer №1

Instead of setting the onChange event on FlatButton, try setting it on the input element. Here's how you can do it:

<FlatButton
      icon={<i className="material-icons">attachment</i>}
      onClick={e => this._handleChange(e)}
>
    <input type="file" onChange={this._handleFileUpload.bind(this)}/>
</FlatButton>

Then, in your onChange method, you can access the selected file using e.target.files:

_handleFileUpload(e){
   console.log(e.target.files);
}

Answer №2

It's a good practice to enclose the button within a label and set it up to trigger the hidden file input.

<label htmlFor={id}>
  <FlatButton />
</label>
<input type="file" id={id} onChange={(e) => {
  const file = e.target.files[0];
  // perform necessary actions
}}

Create a random ID in the constructor to use in this scenario.
