使用jquery显示自定义样式输入文件的文件名

a_fathy • 5 年前 • 1453 次点击

我使用css设置了文件输入的样式:

.custom-file-upload {
  border: 1px solid #ccc;
  display: inline-block;
  padding: 6px 12px;
  cursor: pointer; 
}

<form>
  <label for="file-upload" class="custom-file-upload">
    <i class="fa fa-cloud-upload"></i> Upload Image
  </label>
  <input id="file-upload" name='upload_cont_img' type="file" style="display:none;">
</form>

一切正常,但我想显示选定的文件名。如何使用css或jquery实现这一点?

我有一个很长的裂缝我希望它能帮助你可能需要更适合你的风格

HTML

<form>
  <label for="file-upload" class="custom-file-upload">
    <i class="fa fa-cloud-upload"></i> Upload Image
  </label>
  <input id="file-upload" name='upload_cont_img' type="file"     style="display:none;">
  <input id="uploadFile" placeholder="No File" disabled="disabled" />
</form>

CSS

.custom-file-upload {
  border: 1px solid #ccc;
  display: inline-block;
  padding: 6px 12px;
  cursor: pointer;
}

#uploadFile {
  text-align: center;
  border: none;
  background-color: white;
  color: black;
}

javascript

document.getElementById("file-upload").onchange = function() {
  document.getElementById("uploadFile").value = this.value;
};

上载按钮样式

input[type="file"] {
    display: none;
}
.custom-file-upload {
    border: 1px solid #ccc;
    display: inline-block;
    padding: 6px 12px;
    cursor: pointer;
}

<label for="file-upload" class="custom-file-upload">
    <i class="fa fa-cloud-upload"></i> Custom Upload
</label>
<input id="file-upload" type="file"/>

仅用于css解决方案

.file_upload {
  position: relative;
  min-width: 90px;
  text-align: center;
  color: #ee3333;
  line-height: 25px;
  background: #fff;
  border: solid 2px #ee3333;
  font-weight: 600;
}

a.file_upload {
  display: inline-block;
}

.file_upload .btn_lbl {
  position: relative;
  z-index: 2;
  pointer-events: none;
}

.file_upload .btn_colorlayer {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background: #fff;
  z-index: 1;
  pointer-events: none;
}

.file_upload input[type="file"] {
  position: absolute;
  top: 3px;
  left: -86px;
  font-weight: 600;
  margin-left: 100%;
  color: #ee3333;
  outline: none;
}

<button class="file_upload" type="button">
      <span class="btn_lbl">Browse</span>
      <span class="btn_colorlayer"></span>
      <input type="file" name="fileupload" id="file_upload" />
    </button>

你也可以用它上传多个文件

updateList = function() {
  var input = document.getElementById('file');
  var output = document.getElementById('fileList');

  output.innerHTML = '<ul>';
  for (var i = 0; i < input.files.length; ++i) {
    output.innerHTML += '<li>' + input.files.item(i).name + '</li>';
  }
  output.innerHTML += '</ul>';
}

<input type="file" name="file" id="file" multiple 
       onchange="javascript:updateList()" />
<br/>Selected files:
<div id="fileList"></div>

你可以用这样的文件名

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

输入更改时需要获取文件名并将其插入HTML。在代码中 this.files[0].name 获取所选文件的名称。

$("#file-upload").change(function(){
  $("#file-name").text(this.files[0].name);
});

$("#file-upload").change(function(){
  $("#file-name").text(this.files[0].name);
});

.custom-file-upload {
    border: 1px solid #ccc;
    display: inline-block;
    padding: 6px 12px;
    cursor: pointer; 
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
    <label for="file-upload" class="custom-file-upload">
        <i class="fa fa-cloud-upload"></i> Upload Image
    </label>
    <input id="file-upload" name='upload_cont_img' type="file" style="display:none;">
    <label id="file-name"></label>
</form>

你也可以用 纯javascript

document.querySelector("#file-upload").onchange = function(){
  document.querySelector("#file-name").textContent = this.files[0].name;
}

document.querySelector("#file-upload").onchange = function(){
  document.querySelector("#file-name").textContent = this.files[0].name;
}

.custom-file-upload {
  border: 1px solid #ccc;
  display: inline-block;
  padding: 6px 12px;
  cursor: pointer; 
}

<form>
  <label for="file-upload" class="custom-file-upload">
    <i class="fa fa-cloud-upload"></i> Upload Image
  </label>
  <input id="file-upload" name='upload_cont_img' type="file" style="display:none;">
  <label id="file-name"></label>
</form>

您必须绑定并触发 [type=file] 元素并将文件名读取为:

$('#file-upload').change(function() {
  var i = $(this).prev('label').clone();
  var file = $('#file-upload')[0].files[0].name;
  $(this).prev('label').text(file);
});

.custom-file-upload {
  border: 1px solid #ccc;
  display: inline-block;
  padding: 6px 12px;
  cursor: pointer;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
  <label for="file-upload" class="custom-file-upload">
    <i class="fa fa-cloud-upload"></i> Upload Image
  </label>
  <input id="file-upload" name='upload_cont_img' type="file" style="display:none;">
</form>
