Bootstrap File Upload clone


I am using Krajee's Bootstrap file upload plugin for file input & I am trying to clone the file input so that users can add multiple files from different folders rather than selecting it at once. The issue I am facing is after the file input gets cloned, it behaves weirdly. I have setup a fiddle for this. When I am trying to reset or clear the file input, it always clears the first input. Have been trying a lot of options & after spending so many hours decided to post here. JS Fiddle: https://jsfiddle.net/asfg9mna/

Any ideas as to how to make it work fine? Issue is whenever i click on delete icon, it always deletes the first input's file & not the current one.

HTML code:

<form role="form" id="upload-form" class="form-horizontal">
    <div class="addFiles text-nowrap">
        <div class="appendClass form-group" style="margin-bottom: 1.5%;">
            <label class="col-md-2 control-label" for="input-2">Select Files</label>
            <div class="col-md-9 col-9-input uploadFile">
                <input placeholder="Select Files" id="input-2" name="input2[]" type="file" class="file input-upload" data-show-upload="false" data-show-preview="false">
            </div>
            <button type="button" class="btn btn-box-tool addFilesBtn" data-toggle="tooltip" title="Click to add more files">
                <i class="fa fa-plus"> </i>
            </button>
            <button type="button" class="btn btn-box-tool closeFilesBtn" data-toggle="tooltip" title="Click to remove this block">
                <i class="fa fa-times"> </i>
            </button>
        </div>
    </div>
</form>

JS Code:

//Clone Upload File Div
$(document).on('click', ".addFilesBtn", function(e) {
    e.preventDefault();
    $(this).tooltip('hide');
    $(".appendClass:first").clone(true).appendTo(".addFiles");
    $('.closeFilesBtn').show();
    $('.closeFilesBtn:first').hide();
    //$fileInput = $('.input-upload');
    //$fileInput.replaceWith( $fileInput = $fileInput.clone( true ) );
    //$('.input-upload').fileinput('clear').fileinput();
    $('.uploadFile').next().trigger('reset');
});

Solution

  • Here is jsfiddle

    Update your js code like this,

    $(document).on('click', ".addFilesBtn", function(e) {
      e.preventDefault();
      $(this).tooltip('hide');
      parent_element = $(".appendClass:first");
      $(".input-upload").fileinput('destroy');
      element = parent_element.clone();
      element.appendTo(".addFiles");
      $(".input-upload").fileinput();
    
      $('.closeFilesBtn').show();
      $('.closeFilesBtn:first').hide();
      //$fileInput = $('.input-upload');
      //$fileInput.replaceWith( $fileInput = $fileInput.clone( true ) );
      //$('.input-upload').fileinput('clear').fileinput();
      //$('.uploadFile').next().trigger('reset');
    });
    

    And please write your code to update ids of every elements which will be cloned.

    EDIT

    $(document).on('click', ".addFilesBtn", function(e) {
      e.preventDefault();
      $(this).tooltip('hide');
      $(".has_clone").each(function() {
        $this = $(this);
        var parent_element = $(this).closest(".appendClass");
        var $element = parent_element.clone();
        $element.find(".file-input").remove();
        var counter = parseInt($("#counter").val()) + 1;
        $element.find(".col-md-9").append('<input placeholder="Select Files" id="input-' + counter + '" name="input2[]" type="file" class="file dynamic_clone input-upload " data-show-upload="false" data-show-preview="false">');
        $("#counter").val(counter);
        $element.appendTo(".addFiles");
        $(".input-upload").fileinput({
          'showPreview': true
        });
      });
    $('.closeFilesBtn').show();
      $('.closeFilesBtn:first').hide();
    });
    
    //Close addFile div - Upload files
    $(document).on('click', ".closeFilesBtn", function(e) {
      e.preventDefault();
      $(this).closest(".appendClass").hide();
    });
    

    Thanks
