Javascript用光标擦除图像 [英] Javascript erase image with cursor

问题描述

有可能使用javascript吗？

Is it possible with javascript?

我试图实现一个刮刮卡类型的东西，我想知道用户是否可以用他的光标

I'm trying to implement a scratchcard type thing, and I was wondering if the user could 'scratch it' with his cursor and then javascript would remove/erase the image to show the text below.

但我没有找到任何可以擦除abit（光标）的任何东西（javascript明智的）位置）。

But i've not been able to find anything (javascript wise) which can erase abit (cursor location) of an image.

有没有任何建议/想法？

Does anyone have any suggestions/ideas?
