Javascript 我如何上传带有表单中名称的网络摄像头快照?
我有一个插件,可以拍摄快照并将jpg上传到服务器。现在,我使用函数date('YmdHis')。jpg'来命名文件。但是我想在我的html文件中给出文件名。我有4个文件:TEST.HTLM和我的html,WEBCAM.JS和一些JS,TEST.PHP和服务器函数。我有webcam.swf文件,它将图片传递到TEST.PHP 非常感谢你 这是我的代码: TEST.HTMLJavascript 我如何上传带有表单中名称的网络摄像头快照?,javascript,php,webcam.js,Javascript,Php,Webcam.js,我有一个插件,可以拍摄快照并将jpg上传到服务器。现在,我使用函数date('YmdHis')。jpg'来命名文件。但是我想在我的html文件中给出文件名。我有4个文件:TEST.HTLM和我的html,WEBCAM.JS和一些JS,TEST.PHP和服务器函数。我有webcam.swf文件,它将图片传递到TEST.PHP 非常感谢你 这是我的代码: TEST.HTML <html lang="en"> <body> <table&
