這裡採用 span標籤巢狀input標籤，因為div標籤在ie裡有問題，具體參考該文章：http://www.cnblogs.com/kongxianghai/p/5624785.html

裡面很詳細，程式碼如下：

<style>
        .fileinput-button {
            position: relative;
            display: inline-block;
            overflow: hidden;
        }

        .fileinput-button input{
            position
 
:absolute;
            right: 0px;
            top: 0px;
            opacity: 0;
            -ms-filter: 'alpha(opacity=0)';
            font-size: 200px;
            cursor: pointer;
        }
        .btn-success{
            height: 55px;
            display: inline-block;
            border-radius: 5px
 
;
            line-height: 3.3;
            border: 1px solid rgb(90, 90, 90);
            background-color: #00C1B3;
            font-size: 18px;
            width: 45%;
            color: rgb(69, 69, 69);
            text-align: center;
            margin-top: 100px;
            cursor: pointer;
        }
    </
 
style>
</head>

body裡面是：

<span class="btn-success fileinput-button">
<span>上傳</span>
<input type="file">
