关于claviska的答案-如果你想在一个基本的文件上传中显示上传的文件名，你可以在输入的onchange事件中这样做。只需使用以下代码:

 <label class="btn btn-default">
                    Browse...
                    <span id="uploaded-file-name" style="font-style: italic"></span>
                    <input id="file-upload" type="file" name="file"
                           onchange="$('#uploaded-file-name').text($('#file-upload')[0].value);" hidden>
 </label>

这个jquery JS代码负责检索上传的文件名:

$('#file-upload')[0].value

或者用香草JS:

document.getElementById("file-upload").value

不需要额外的插件，这个bootstrap解决方案非常适合我:

<div style="position:relative;">
        <a class='btn btn-primary' href='javascript:;'>
            Choose File...
            <input type="file" style='position:absolute;z-index:2;top:0;left:0;filter: alpha(opacity=0);-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";opacity:0;background-color:transparent;color:transparent;' name="file_source" size="40"  onchange='$("#upload-file-info").html($(this).val());'>
        </a>
        &nbsp;
        <span class='label label-info' id="upload-file-info"></span>
</div>

这对我来说非常合适

<span>
    <input  type="file" 
            style="visibility:hidden; width: 1px;" 
            id='${multipartFilePath}' name='${multipartFilePath}'  
            onchange="$(this).parent().find('span').html($(this).val().replace('C:\\fakepath\\', ''))"  /> <!-- Chrome security returns 'C:\fakepath\'  -->
    <input class="btn btn-primary" type="button" value="Upload File.." onclick="$(this).parent().find('input[type=file]').click();"/> <!-- on button click fire the file click event -->
    &nbsp;
    <span  class="badge badge-important" ></span>
</span>

从上面的其他文章中得到一些灵感，这里有一个完整的解决方案，它结合了一个看起来像表单控制字段的输入组插件，用于一个干净的文件输入小部件，其中包括到当前文件的链接。

.input-file { position: relative; margin: 60px 60px 0 } /* Remove margin, it is just for stackoverflow viewing */ .input-file .input-group-addon { border: 0px; padding: 0px; } .input-file .input-group-addon .btn { border-radius: 0 4px 4px 0 } .input-file .input-group-addon input { cursor: pointer; position:absolute; width: 72px; z-index:2;top:0;right:0;filter: alpha(opacity=0);-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";opacity:0; background-color:transparent; color:transparent; } <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css"> <div class="input-group input-file"> <div class="form-control"> <a href="/path/to/your/current_file_name.pdf" target="_blank">current_file_name.pdf</a> </div> <span class="input-group-addon"> <a class='btn btn-primary' href='javascript:;'> Browse <input type="file" name="field_name" onchange="$(this).parent().parent().parent().find('.form-control').html($(this).val());"> </a> </span> </div>

Bootstrap中漂亮的文件输入字段

更新

jQuery插件风格:

// Based in: http://duckranger.com/2012/06/pretty-file-input-field-in-bootstrap/
// Version: 0.0.3
// Compatibility with: Bootstrap 3.2.0 and jQuery 2.1.1
// Use:
//     <input class="nice_file_field" type="file" data-label="Choose Document">
//     <script> $(".nice_file_field").niceFileField(); </script>
//
(function( $ ) {
  $.fn.niceFileField = function() {
    this.each(function(index, file_field) {
      file_field = $(file_field);
      var label = file_field.attr("data-label") || "Choose File";

      file_field.css({"display": "none"});

      nice_file_block_text  = '<div class="input-group nice_file_block">';
      nice_file_block_text += '  <input type="text" class="form-control">';
      nice_file_block_text += '  <span class="input-group-btn">';
      nice_file_block_text += '   <button class="btn btn-default nice_file_field_button" type="button">' + label + '</button>';
      nice_file_block_text += '  </span>';
      nice_file_block_text += '</div>';

      file_field.after(nice_file_block_text);

      var nice_file_field_button = file_field.parent().find(".nice_file_field_button");
      var nice_file_block_element = file_field.parent().find(".nice_file_block");

      nice_file_field_button.on("click", function(){ console.log("click"); file_field.click() } );
      file_field.change( function(){
        nice_file_block_element.find("input").val(file_field.val());
      });
    });
  };
})( jQuery );

这是我喜欢的最好的文件上传风格:

<div class="fileupload fileupload-new" data-provides="fileupload">
  <div class="input-append">
    <div class="uneditable-input span3"><i class="icon-file fileupload-exists"></i> <span class="fileupload-preview"></span></div><span class="btn btn-file"><span class="fileupload-new">Select file</span><span class="fileupload-exists">Change</span><input type="file" /></span><a href="#" class="btn fileupload-exists" data-dismiss="fileupload">Remove</a>
  </div>
</div>

你可以得到演示和更多的风格:

但是使用这个，你应该用jasny bootstrap文件替换twitter bootstrap ..

的问候。
