任务:将照片上传到filepicker的PhoneGap应用程序。

  • 我设法在应用程序中使用Filepicker。
  • 我设法使用原生输入的其他上传器:http://blueimp.github.io/jQuery-File-Upload/
  • 无法管理的是使用原生(iOS6)上传到Filepicker 输入类型=“文件”

    <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>

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

额外点:如何使用像{ - 3}} (用于客户端图像大小调整的插件)这样的库来减少文件大小,以便在使用疯狂的3G连接传输数据之前?

提前感谢您提出任何建议和支持。

您可以使用filepicker.store函数存储本机输入类型,例如:

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

这是一个最小的代码片段(上传大型照片需要时间,而且没有进度条,所以请耐心等待)

    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>
