诀窍是在点击文件输入时触发一个点击事件，并通过CSS管理默认输入文件的可见性。你可以这样做: jQuery:

$(function() {
  $("#labelfile").click(function() {
    $("#imageupl").trigger('click');
  });
})

css

.file {
  position: absolute;
  clip: rect(0px, 0px, 0px, 0px);
  display: block;
}

.labelfile {
  color: #333;
  background-color: #fff;
  display: inline-block;
  margin-bottom: 0;
  font-weight: 400;
  text-align: center;
  vertical-align: middle;
  cursor: pointer;
  background-image: none;
  white-space: nowrap;
  padding: 6px 8px;
  font-size: 14px;
  line-height: 1.42857143;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

HTML代码:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div>
  <input name="imageupl" type="file" id="imageupl" class="file" />
  <label class="labelfile" id="labelfile"><i class="icon-download-alt"></i> Browse File</label>
</div>

我的解决方案…

HTML:

<input type="file" id="uploadImages" style="display:none;" multiple>

<input type="button" id="callUploadImages" value="Select">
<input type="button" id="uploadImagesInfo" value="0 file(s)." disabled>
<input type="button" id="uploadProductImages" value="Upload">

Jquery:

$('#callUploadImages').click(function(){

    $('#uploadImages').click();
});

$('#uploadImages').change(function(){

    var uploadImages = $(this);
    $('#uploadImagesInfo').val(uploadImages[0].files.length+" file(s).");
});

这是邪恶的:D

这应该可以工作:

input.*className*::-webkit-file-upload-button {
  *style content..*
}

这是不可能的。否则，你可能需要使用Silverlight或Flash上传控件。

我将使用一个按钮来触发输入:

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

快速干净。

$(document).ready(function () { $('#choose-file').change(function () { var i = $(this).prev('label').clone(); var file = $('#choose-file')[0].files[0].name; $(this).prev('label').text(file); }); }); .custom-file-upload{ background: #f7f7f7; padding: 8px; border: 1px solid #e3e3e3; border-radius: 5px; border: 1px solid #ccc; display: inline-block; padding: 6px 12px; cursor: pointer; } <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> can you try this <label for="choose-file" class="custom-file-upload" id="choose-file-label"> Upload Document </label> <input name="uploadDocument" type="file" id="choose-file" accept=".jpg,.jpeg,.pdf,doc,docx,application/msword,.png" style="display: none;" />
