解决方案

在您的网页捕获是合乎逻辑的看不到任何用户有它的类型 - 其实是不存在的，你只要把负荷页面，你期望看到的文本框？

如果您尝试获得调试理由的报告，你赢了，看在这个问题的时刻在页面上发生的事情，那么你需要使用建立一个JavaScript库（他能）页面的DOM和它发送给你。所有这些行动要求用户使他们 - 捕捉网页和电子邮件发送，即使你可以让它自动完成，如果他愿意为你展示他们有什么类型的用户必须嗤

。

一个例子 http://experiments.hertzen.com/jsfeedback/ 和库<一个HREF =htt​​p://html2canvas.hertzen.com/相对=nofollow> http://html2canvas.hertzen.com/ ，可以捕捉用户在屏幕上看到的东西。

解决方案

When you make a capture of the web page is logical to not see anything that the user have type on it - Actually is not exist, you just make a load of the page, what you expect to see on text boxes ?

If you try to get a report for debug reasons and you won to see what happens on the page at the moment of the issue then you need to use a javascript library that build (as he can) the dom of the page and send it to you. All this actions request the user to make them - to capture the web page and send it with email, even if you can make it automate, the user must deride if he like to show you what have type on them.

An example http://experiments.hertzen.com/jsfeedback/ and the library http://html2canvas.hertzen.com/ that can capture what the user see on screen.
