HTML5手机端拍照上传

1、accept="image/*" capture="camera" 自动调用手机端拍照功能

accept="image/*" capture="camera"

2、当表单提交时候有文件的时候，需要加上

var formData = new FormData($( "form" )[0]);

 

3、示例代码：

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">
        <script src="http://code.jquery.com/jquery-2.1.1.min.js"></script>

        <style>
             .list_box { 
                display: -webkit-box;  
                width: 90%; 
                margin: 0px auto;   
                border: 1px solid silver;
                padding: 3px;

            }  
            .list input {
                width: 100%;

                background: #008000;
            }
        </style>

    <body>
      <form method="" action=""  enctype="multipart/form-data" role="form">
