我使用http://gregpike.net/demos/bootstrap-file-input/demo.html:

$('input[type=file]').bootstrapFileInput();

or

$('.file-inputs').bootstrapFileInput();

这是珍妮的自举叉里的。

可以使用。创建简单的上传按钮

<span class="btn btn-file">Upload<input type="file" /></span>

使用fileupload插件，您可以创建更高级的小部件。看一看 http://jasny.github.io/bootstrap/javascript/#fileinput

下面的代码与上面的图片一样

Html

<form>
<div class="row">
<div class="col-lg-6">
<label for="file">
<div class="input-group">
<span class="input-group-btn">
<button class="btn btn-default" type="button">Browse</button>
</span>
<input type="text" class="form-control" id="info" readonly="" style="background: #fff;" placeholder="Search for...">
</div><!-- /input-group -->
</label>
</div><!-- /.col-lg-6 -->
</div>

</div>
<input type="file" style="display: none;" onchange="$('#info').val($(this).val().split(/[\\|/]/).pop()); " name="file" id="file">
</form>

Javascript

<script type="text/javascript">

$(function() {
    $("label[for=file]").click(function(event) {
        event.preventDefault();
        $("#file").click();
    });
});

</script>

我已经创建了一个自定义上传按钮，只接受图像，这可以根据您的要求修改。

希望这能有所帮助!!：）

(已使用的Bootstrap框架)

代码笔链接

HTML

<center>
 <br />
 <br />
 <span class="head">Upload Button Re-Imagined</span>
 <br />
 <br />
 <div class="fileUpload blue-btn btn width100">
   <span>Upload your Organizations logo</span>
   <input type="file" class="uploadlogo" />
 </div>
</center>

CSS

 .head {
   font-size: 25px;
   font-weight: 200;
 }

 .blue-btn:hover,
 .blue-btn:active,
 .blue-btn:focus,
 .blue-btn {
   background: transparent;
   border: solid 1px #27a9e0;
   border-radius: 3px;
   color: #27a9e0;
   font-size: 16px;
   margin-bottom: 20px;
   outline: none !important;
   padding: 10px 20px;
 }

 .fileUpload {
   position: relative;
   overflow: hidden;
   height: 43px;
   margin-top: 0;
 }

 .fileUpload input.uploadlogo {
   position: absolute;
   top: 0;
   right: 0;
   margin: 0;
   padding: 0;
   font-size: 20px;
   cursor: pointer;
   opacity: 0;
   filter: alpha(opacity=0);
   width: 100%;
   height: 42px;
 }


 /*Chrome fix*/

 input::-webkit-file-upload-button {
   cursor: pointer !important;
 }

JS

// You can modify the upload files to pdf's, docs etc
//Currently it will upload only images
$(document).ready(function($) {

  // Upload btn
  $(".uploadlogo").change(function() {
    readURL(this);
  });

  function readURL(input) {
    var url = input.value;
    var ext = url.substring(url.lastIndexOf('.') + 1).toLowerCase();
    if (input.files && input.files[0] && (ext == "png" || ext == "jpeg" || ext == "jpg" || ext == "gif" || ext == "svg")) {
      var path = $('.uploadlogo').val();
      var filename = path.replace(/^.*\\/, "");
      $('.fileUpload span').html('Uploaded logo : ' + filename);
      // console.log(filename);
    } else {
      $(".uploadlogo").val("");
      $('.fileUpload span').html('Only Images Are Allowed!');
    }
  }
});

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>

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 );
