<input id="lefile" type="file" style="display:none"> 
<div class="input-append"> 
<input id="photoCover" class="input-large" type="text" style="height:30px;"> 
<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

其實這個就是拼接出來的，然后js控制顯示文件名。

效果如下：

二 bootstrap-filestyle

http://markusslima.github.io/bootstrap-filestyle/

注意：此樣式只能使用bootstrap2的css，版本為bootstrap3的css是不兼容的?。。▼尩拔揖鸵驗檫@個測試了老半天。。摔

效果如下：

三 bootstrap-file-input

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

<!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> 
</body> 
</html>

引入了bootstrap.file-input.js但是直接引入有點小問題，說找不到bootstrapFileInput這個方法。于是我就改了一點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() { 
這里我直接用這個方法，把前面一行刪掉就可以了 
this.each(function(i,elem){ 
.........中間省略 
// 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[type=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，到了看效果的時候啦~~

四 Fine Uploader

http://fineuploader.com/demos.html

在官網(wǎng)下載是收費的。。我在github下載了一個。

下載鏈接

下載解壓后是這樣的：

manualuploader.fineUploader('uploadStoredFiles');

$(document).ready(function () { 
$('#fine-uploader').fineUploader({

js和css，你們在文件夾里搜索就能找到，但是有一個all.fineuploader-4.3.1.min.js，是我在官網(wǎng)用chrome審查元素copy下來的。。經(jīng)測試可以用

注意中間代碼中的Template

如果沒有這一段，console將會報錯：
