BootStrap⽂件上传样式超好看【持续更新】⼀直接使⽤bootstrap，利⽤简单的js控制
⾮常简单，代码如下：
<input id="lefile" type="file" >
<div class="input-append">
layui和bootstrap哪个好<input id="photoCover" class="input-large" type="text" >
<a class="btn" onclick="$('input[id=lefile]').click();">Browse</a>
</div>
<script type="text/javascript">
$('input[id=lefile]').change(function() {
$('#photoCover').val($(this).val());
});
</script>
效果如下：
不需要任何其他的js和css，只需要引⼊bootstrap和jQuery即可
其实这个就是拼接出来的，然后js控制显⽰⽂件名。
效果如下：
⼆ bootstrap-filestyle
注意：此样式只能使⽤bootstrap2的css，版本为bootstrap3的css是不兼容的！！（我就因为这个测试了⽼半天。。摔
效果如下：
三 bootstrap-file-input
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>bootstrap.file-input</title>
<link href="css/bootstrap.min.css" rel="stylesheet" />
<script type="text/javascript" src="js/jquery-2.0.3.min.js"></script>
<script type="text/javascript" src="js/bootstrap.min.js"></script>
<script type="text/javascript" src="js/bootstrap.file-input.js"></script>
</head>
<body>
<!-- Change the wording using a title tag -->
<input type="file" title="Search for a file to add 1" class="btn-primary">
<br>
<br>
<input type="file" title="Search for a file to add 2" class="btn btn-primary">
<br>
<br>
<input type="file" title="Search for a file to add 3" class="btn-primary">
<br>
<br>
<input type="file" title="Search for a file to add 4" class="btn-primary">
<br>
<br>
<br>
<br>
<br>
Disable the styling:
<!-- Disable the styling -->
<input type="file" data-bfi-disabled>
<script type="text/javascript">
$('input[type=file]').bootstrapFileInput();
</script>
</html>
引⼊了bootstrap.file-input.js但是直接引⼊有点⼩问题，说不到bootstrapFileInput这个⽅法。于是我就改了⼀点js：
/*
Bootstrap - File Input
======================
This is meant to convert all file input tags into a set of elements that displays consistently in all browsers.
Converts all
<input type="file">
into Bootstrap buttons
<a class="btn">Browse</a>
*/
$.fn.bootstrapFileInput = function() {
这⾥我直接⽤这个⽅法，把前⾯⼀⾏删掉就可以了
this.each(function(i,elem){
.........中间省略
// Add the styles before the first stylesheet
// This ensures they can be easily overridden with developer styles
var cssHtml = '<style>'+
'.file-input-wrapper { overflow: hidden; position: relative; cursor: pointer; z-index: 1; }'+
'.file-input-wrapper input[type=file], .file-input-wrapper input[type=file]:focus, .file-input-wrapper input[t
ype=file]:hover { position: absolute; top: 0; left: 0; cursor: pointer; opacity: 0; filter: alpha(opacity=0); z-index: 99; outline: 0; }'+ '.file-input-name { margin-left: 8px; }'+
'</style>';
$('link[rel=stylesheet]').eq(0).before(cssHtml);
};
好了，到了看效果的时候啦~~
四 Fine Uploader
在官⽹下载是收费的。。我在github下载了⼀个。
下载解压后是这样的：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>bootstrap.file-input</title>
<link href="css/bootstrap.min.css" rel="stylesheet" />
<link href="css/fineuploader.css" rel="stylesheet" />
<script type="text/javascript" src="js/jquery-2.0.3.min.js"></script>
<script type="text/javascript" src="js/bootstrap.min.js"></script>
<script type="text/javascript" src="js/all.fineuploader-4.3.1.min.js"></script>
</head>
<body>
<br>
<div id="manual-fine-uploader"></div>
<div id="triggerUpload" class="btn btn-primary" >
<i class="icon-upload icon-white"></i> Upload now
</div>
<script>
$(document).ready(function() {
var manualuploader = $('#manual-fine-uploader').fineUploader({
request: {
endpoint: 'server/handleUploads'
},
autoUpload: false,
text: {
uploadButton: '<i class="icon-plus icon-white"></i> Select Files'
}
$('#triggerUpload').click(function() {
manualuploader.fineUploader('uploadStoredFiles');
});
});
</script>
<script>
$(document).ready(function () {
$('#fine-uploader').fineUploader({
request: {
endpoint: 'server/handleUploads'
}
});
});
</script>
<!-- Fine Uploader CSS
====================================================================== -->
<!-- Fine Uploader DOM Element
====================================================================== -->
<div id="fine-uploader"></div>
<!-- Fine Uploader template
====================================================================== -->
<script type="text/template" id="qq-template">
<div class="qq-uploader-selector qq-uploader">
<div class="qq-upload-drop-area-selector qq-upload-drop-area" qq-hide-dropzone>
<span>Drop files here to upload</span>
</div>
<div class="qq-upload-button-selector qq-upload-button">
<div>Upload a file</div>
</div>
<span class="qq-drop-processing-selector qq-drop-processing">
<span>Processing </span>
<span class="qq-drop-processing-spinner-selector qq-drop-processing-spinner"></span>
</span>
<ul class="qq-upload-list-selector qq-upload-list">
<li>
<div class="qq-progress-bar-container-selector">
<div class="qq-progress-bar-selector qq-progress-bar"></div>
</div>
<span class="qq-upload-spinner-selector qq-upload-spinner"></span>
<span class="qq-edit-filename-icon-selector qq-edit-filename-icon"></span>
<span class="qq-upload-file-selector qq-upload-file"></span>
<input class="qq-edit-filename-selector qq-edit-filename" tabindex="0" type="text">
<span class="qq-upload-size-selector qq-upload-size"></span>
<a class="qq-upload-cancel-selector qq-upload-cancel" href="#">Cancel</a>
<a class="qq-upload-retry-selector qq-upload-retry" href="#">Retry</a>
<a class="qq-upload-delete-selector qq-upload-delete" href="#">Delete</a>
<span class="qq-upload-status-text-selector qq-upload-status-text"></span>
</li>
</ul>
</div>
</script>
</body>
</html>
js和css，你们在⽂件夹⾥搜索就能到，但是有⼀个all.fineuploader-4.3.1.min.js，是我在官⽹⽤chrome审查元素copy下来的。。经测试可以⽤注意中间代码中的Template
如果没有这⼀段，console将会报错：
然后我查到⼀个原因：
⼤家可以阅读下，就是必须要有⼀个模板⽂件才可以运⾏。
效果如下：（没导css对应的图⽚有点丑）
以上内容是⼩编给⼤家介绍的BootStrap⽂件上传样式的相关内容，希望对⼤家有所帮助！
