• 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>
