Get filename from input [type='file'] using jQuery

Question

This is the uploaded form.

<form class="alert alert-info">
    <div>
        <b id = "select_file" class="span3" style="font-weight: bold; cursor: pointer; ">Please select image</b>
        <input class="span3" type="file" name="image_file" id="image_file" style="display:none " />
        <input disabled="true" type="button" value="Upload image" class="btn" />
    </div>
</form>

I use the following script to open a window with files. I want to show a file name in <b id = 'select_file'>.

How can I do this?

$('#select_file').click(function(){
    var _this = $(this);
    $('#image_file').show().focus().click().hide();

    var filename = $('#image_file').val();
    _this.html(filename);

    $('.btn').attr('disabled', false);
});

Answer 1

Using Bootstrap

Remove form-control-file Class from input field to avoid unwanted horizontal scroll bar

Try this!!

$('#upload').change(function() {
    var filename = $('#upload').val();
    if (filename.substring(3,11) == 'fakepath') {
        filename = filename.substring(12);
    } // For Remove fakepath
    $("label[for='file_name'] b").html(filename);
    $("label[for='file_default']").text('Selected File: ');
    if (filename == "") {
        $("label[for='file_default']").text('No File Choosen');
    }
});

.custom_file {
  margin: auto;
  opacity: 0;
  position: absolute;
  z-index: -1;
}

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="form-group">
   <label for="upload" class="btn btn-sm btn-primary">Upload Image</label>
    <input type="file" class="text-center form-control-file custom_file" id="upload" name="user_image">
    <label for="file_default">No File Choosen </label>
    <label for="file_name"><b></b></label>
</div>

Answer 2

If selected more 1 file:

$("input[type="file"]").change(function() {
   var files = $("input[type="file"]").prop("files");
   var names = $.map(files, function(val) { return val.name; });
   $(".some_div").text(names);
});

files will be a FileList object. names is an array of strings (file names).

Try this to Get filename from input [type='file'] using jQuery.

<script type="text/javascript">
    $(document).ready(function(){
        $('input[type="file"]').change(function(e){
            var fileName = e.target.files[0].name;
            alert('The file "' + fileName +  '" has been selected.');
        });
    });
</script>

Answer 4

You can access to the properties you want passing an argument to your callback function (like evt), and then accessing the files with it (evt.target.files[0].name) :

$("document").ready(function(){
  $("main").append('<input type="file" name="photo" id="upload-photo"/>');
  $('#upload-photo').on('change',function(evt) {
    alert(evt.target.files[0].name);
  });
});

Answer 5

$("#filetosend").prop('files')[0]

Answer 6

Getting the file name is fairly easy. As matsko points out, you cannot get the full file path on the user's computer for security reasons.

var file = $('#image_file')[0].files[0]
if (file){
  console.log(file.name);
}

Answer 7

This isn't possible due to security reasons. At least not on modern browsers. This is because any code getting access to the path of the file can be considered dangerous and a security risk. Either you'll end up with an undefined value, an empty string or an error will be thrown.

When a file form is submitted, the browser buffers the file temporarily into an upload directory and only the temporary file name of that file and basename of that file is submitted.

Answer 8

You have to do this on the change event of the input type file this way:

$('#select_file').click(function() {
    $('#image_file').show();
    $('.btn').prop('disabled', false);
    $('#image_file').change(function() {
        var filename = $('#image_file').val();
        $('#select_file').html(filename);
    });
});​

Answer 9

var file = $('#YOURID > input[type="file"]'); file.value; // filename will be,

In Chrome, it will be something like C:\fakepath\FILE_NAME or undefined if no file was selected.

It is a limitation or intention that the browser does not reveal the file structure of the local machine.

Answer 10

This was a very important issue for me in order for my site to be multilingual. So here is my conclusion tested in Firefox and Chrome.

jQuery trigger comes in handy.

So this hides the standard boring type=file labels. You can place any label you want and format anyway. I customized a script from http://demo.smarttutorials.net/ajax1/. The script allows multiple file uploads with thumbnail preview and uses PHP and MySQL.

<form enctype="multipart/form-data" name='imageform' role="form"    ="imageform" method="post" action="upload_ajax.php">
    <div class="form-group">
        <div id="select_file">Select a file</div>
        <input class='file' type="file" style="display: none " class="form-control" name="images_up" id="images_up" placeholder="Please choose your image">
        <div id="my_file"></div>
        <span class="help-block"></span>
    </div>
    <div id="loader" style="display: none;">
        Please wait image uploading to server....
    </div>
    <input type="submit" value="Upload" name="image_upload" id="image_upload" class="btn"/>
</form>

$('#select_file').click(function() {
    $('#images_up').trigger('click');
    $('#images_up').change(function() {
        var filename = $('#images_up').val();
        if (filename.substring(3,11) == 'fakepath') {
            filename = filename.substring(12);
        } // Remove c:\fake at beginning from localhost chrome
        $('#my_file').html(filename);
   });
});

Answer 11

There is no jQuery function for this. You have to access the DOM element and check the files property.

document.getElementById("image_file").files[0];

Or

$('#image_file')[0].files[0]
