How to display selected file names before uploading multiple files in Struts2?

Question

I am using Struts2 to upload multiple files:

<s:file name="files" multiple="multiple" /> 

When I select multiple files it displays the number of files, eg. 3 files.

The project requirements are that the user should be able to see what files he selected before uploading.

Is it possible to display the selected files names in a list or maybe in the control itself ?

You can use the HTML5 files property of the <input type="file" /> element like follows:

updateList = function() {      var input = document.getElementById('file');      var output = document.getElementById('fileList');      var children = "";      for (var i = 0; i < input.files.length; ++i) {          children += '<li>' + input.files.item(i).name + '</li>';      }      output.innerHTML = '<ul>'+children+'</ul>';  }

<input type="file" multiple         name="file"            id="file"      onchange="javascript:updateList()" />    <p>Selected files:</p>    <div id="fileList"></div>
