Есть ли способ проверить размер файла до загрузки на сервер?

 
<input type="file" id="files" name="files[]" multiple />
<output id="list"></output>
<script>
  function handleFileSelect(evt) {
    var files = evt.target.files; // FileList object
    // files is a FileList of File objects. List some properties.
    var output = [];
    for (var i = 0, f; f = files[i]; i++) {
      output.push('<li><strong>', escape(f.name), '</strong> (', f.type || 'n/a', ') - ',
                  f.size, ' bytes, last modified: ',
                  f.lastModifiedDate.toLocaleDateString(), '</li>');
    }
    document.getElementById('list').innerHTML = '<ul>' + output.join('') + '</ul>';
  }
  document.getElementById('files').addEventListener('change', handleFileSelect, false);
</script>
 

 
 
 
    function imgLoad()
    {
    var strT = new String();
    document.getElementById("ShowImg").innerHTML= "";
    strT = document.ModReg.file1.value;
    if(strT != "")
    {
        strT = "<img ;id='Sample' src='" + strT + "' width='100' height='100'></img>";
        document.getElementById("ShowImg").innerHTML= strT;
        if(!LimitedSize())
        {
           alert("File&nbsp;Size is more than 100 KB");
           document.getElementById("ShowImg").innerHTML= "";
        }
    }
    }
 
    function LimitedSize()
    {
    var i;
    var y = document.images;
    for (i=0;i<y.length;i++)
    {
        if((y[i].id) == 'Sample')
        { 
          if(y[i].fileSize&nbsp;> 102400)
              return false;
        }
    }
    return true;
    }
