任务:PhoneGap 应用程序将照片上传到文件选择器。

  • 我设法在应用程序中使用 Filepicker。
  • 我设法使用带有本机输入的其他上传器:http: //blueimp.github.io/jQuery-File-Upload/
  • 但是没有管理的是使用本机(对于iOS6)输入类型=“文件”上传到文件选择器

    <a href="#" onClick="useFilepicker(); return false">Use Filepicker</a>

    <h3>input type=&quot;filepicker&quot;</h3>
    <input type="filepicker"/>
    <!-- Doesn't work, created issue here: https://github.com/Filepicker/filepicker-phonegap/issues/1 -->

    <h3>input type=&quot;file&quot;</h3>
    <form action="_____WHAT TO PUT HERE_____">

    </form>
    <textarea id="base64">Here c:/fakepath/image.jpg path with be</textarea>

    </body>

注意:此代码使用 ChildBrowser 插件,您可能需要按照以下说明操作:https ://github.com/alunny/ChildBrowser/issues/28#issuecomment-15941458

加分项:如何使用类似https://gokercebeci.com/dev/canvasresize的库 (用于客户端图像大小调整的插件)在使用不稳定的 3G 连接传输数据之前减小文件大小?

提前感谢您的任何建议和支持。

您可以使用该filepicker.store函数来存储本机输入类型,例如:

var input = document.getElementById("my-file-input");
filepicker.store(input, {location:'S3'}, function(fpfile){
    console.log(JSON.stringify(fpfile));
});

这是一个有效的最小片段(上传大照片需要时间,并且没有进度条,所以请耐心等待)

<!DOCTYPE html>
<html>
    <head>
        <title>Filepicker PhoneGap iOS6</title>
    </head>

    <script type="text/javascript" src="cordova-2.2.0.js"></script>
    <script type="text/javascript" src="jquery.min.js"></script>
    <script type="text/javascript" src="filepicker.js"></script>
    <script type="text/javascript">

    filepicker.setKey('l5uQ3k7FQ5GoYCHyTdZV'); // No worries: used filepicker's

    $(function(){

     $("input#file").on("change", function() {

        filepicker.store(this, {location:'S3'}, function(fpfile){

            $("<a>", {
                href: fpfile.url,
                text: "See me!"
            }).appendTo("body");

        });
     });
    });
   </script>

    <body>
        <input id="file" type="file"/>
    </body>
</html>
