I want to change default text on button that is "Choose File" when we use input="file".

enter image description here

How can I do this? Also as you can see in image button is on left side of text. How can I put it on right side of text?

I made a script and published it at GitHub: get selectFile.js Easy to use, feel free to clone.


HTML

<input type=file hidden id=choose name=choose>
<input type=button onClick=getFile.simulate() value=getFile>
<label id=selected>Nothing selected</label>


JS

var getFile = new selectFile;
getFile.targets('choose','selected');

Update 2017:

I have done research on how this could be achieved. And the best explanation/tutorial is here: https://tympanus.net/codrops/2015/09/15/styling-customizing-file-inputs-smart-way/

I'll write summary here just in case it becomes unavailable. So you should have HTML:

<input type="file" name="file" id="file" class="inputfile" />
<label for="file">Choose a file</label>

Then hide the input with CSS:

.inputfile {
width: 0.1px;
height: 0.1px;
opacity: 0;
overflow: hidden;
position: absolute;
z-index: -1;}

Then style the label:

.inputfile + label {
font-size: 1.25em;
font-weight: 700;
color: white;
background-color: black;
display: inline-block;
}

Then optionally you can add JS to display the name of the file:

var inputs = document.querySelectorAll( '.inputfile' );
Array.prototype.forEach.call( inputs, function( input )
{
var label    = input.nextElementSibling,
    labelVal = label.innerHTML;

input.addEventListener( 'change', function( e )
{
    var fileName = '';
    if( this.files && this.files.length > 1 )
        fileName = ( this.getAttribute( 'data-multiple-caption' ) || '' ).replace( '{count}', this.files.length );
    else
        fileName = e.target.value.split( '\\' ).pop();

    if( fileName )
        label.querySelector( 'span' ).innerHTML = fileName;
    else
        label.innerHTML = labelVal;
});
});

But really just read the tutorial and download the demo, it's really good.

Use "for" attribute of label for input. 

<div>
  <label for="files" class="btn">Select Image</label>
  <input id="files" style="visibility:hidden;" type="file">
</div>
Below is the code to fetch name of the uploaded file 

$("#files").change(function() {
  filename = this.files[0].name
  console.log(filename);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
      <label for="files" class="btn">Select Image</label>
      <input id="files" style="visibility:hidden;" type="file">
    </div>

Using Bootstrap you can do this thing like below code.

<!DOCTYPE html>
<html lang="en">
<head>
<style>

.btn-file {
  position: relative;
  overflow: hidden;
}
.btn-file input[type=file] {
    position: absolute;
    top: 0;
    right: 0;
    min-width: 100%;
    min-height: 100%;
    font-size: 100px;
    text-align: right;
    filter: alpha(opacity=0);
    opacity: 0;
    outline: none;
    background: white;
    cursor: inherit;
    display: block;
}
</style>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
  <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>
  <span class="btn btn-file">Upload image from here<input type="file">
</body>
</html>

I'd use a button to trigger the input:

<button onclick="document.getElementById('fileUpload').click()">Open from File...</button>
<input type="file" id="fileUpload" name="files" style="display:none" />

Quick and clean.

Each browser has it's own rendition of the control and as such you can't change either the text or the orientation of the control.

There are some "kind of" hacks you may want to try if you want an / solution rather than a Flash or solution.

http://www.quirksmode.org/dom/inputfile.html

http://www.shauninman.com/archive/2007/09/10/styling_file_inputs_with_css_and_the_dom

Personally, because most users stick to their browser of choice, and therefore are probably used to seeing the control in the default rendition, they'd probably get confused if they saw something different (depending on the types of users you're dealing with).
