File input

File inputs are used to select one or more files from a users device storage.

This component requires Javascript

Examples

To render a file input, apply the class a-input to an input type="file" and add a label next to it.

Base

<input type="file" class="a-input" id="file01">
<label for="file01">No file chosen</label>

Sizes

File inputs supports a full spectrum of sizes: -sm, -md, -lg, -xl. The default size is -md.

<input type="file" class="a-input -sm" id="file01">
<label for="file01">No file chosen</label>
<input type="file" class="a-input -md" id="file01">
<label for="file01">No file chosen</label>
<input type="file" class="a-input -lg" id="file01">
<label for="file01">No file chosen</label>
<input type="file" class="a-input -xl" id="file01">
<label for="file01">No file chosen</label>

JavaScript

This component requires JavaScript to update the label content once a file or files have been selected.

Example

var inputFiles = document.querySelectorAll('input[type="file"].a-input');

Array.prototype.forEach.call(inputFiles, function(input) {
  var label = input.nextElementSibling;

  input.addEventListener('change', function(e) {
    var fileName = '';

    if (this.files && this.files.length > 1) {
      fileName = this.files.length + ' files selected';
    } else {
      fileName = e.target.value.split('\\').pop();
    }

    if (fileName) {
      label.innerHTML = fileName;
    }
  });
});
