我一直在努力使这项工作，搜索谷歌和自上周五以来。 我的最终目标是能够拍摄多张带有标题和说明的照片，并将它们上传到服务器，然后显示在网页上。android phonegap相机和图像上传
我到目前为止的内容是：能够给一个图像标题和描述，浏览图库，找到图像并选择它。但是当我这样做的时候，图像随着表单立即上传。我希望能够使用提交按钮来做到这一点。
我也有一个按钮来拍摄图像，并在页面上预览图像。但是当我用相机拍照时，我不知道如何上传表格。我能够使用div和innerHTML调用在屏幕上打印图像数据......但老实说我很迷茫，甚至不知道从哪里开始发布特定的代码片段。因为目前现在存在，我将发布整个页面....

您的浏览方法会调用uploadPhoto，因此它的工作方式应该是这样。对Camera.getPicture的调用不能选择多张照片，如果这是你以后的事情。 –
这是问题的一部分，我想上传照片是独立于浏览..我希望相机能够被用来代替画廊..？ –
有人请向我解释如何提交这个没有图像？只有表格？请 –
