请问能否给这个截图脚本加上鼠标手势或快捷键呢？

很好用的一个网页截屏脚本，可以把整幅（从头到脚）网页另存为图片
可惜每次要到菜单里去点——我的菜单设置ALT打开的，比较麻烦。
请问各位达人能否给这脚本加上鼠标手势或快捷键？或者另推荐一款脚本也好啊
多谢啦 ：）

我还是WebScreenShot，甚少截屏，但是看重它可以把网页中的图片转化为base64

多谢xelnaga大侠

在这里已经解决了，呵呵

多谢

存UTF-8看看

不加修改应该会有多余代码
主要是注意到底哪个function函数是执行你需要的功能的，留意一下括号的封闭，还有一些是往菜单里加东西的，就明显不需要了

哈哈，多谢xelnaga

我用过screengrab，它的全页面截屏不能用……怪哉

我把你给我的代码一股脑扔到“MouseGestures.uc.js”（http://www.xuldev.org/misc/ucjs.php）里面了……

居然都好用，哈哈，多谢多谢

只是划手势的时候以前状态栏里的中文提示“鼠标手势：……”变成了英文的“Gesture：……”

我自己到脚本里找这个单词，改成中文（用EditPlus修改），出来的是乱码……汗

请问大侠，我直接粘贴到MouseGestures.uc.js里面是否有多余的代码呢？要删掉点什么吗？

多谢~~~

我建议你装screengrab这个扩展
如果你执意装脚本

参看一下这贴
https://www.firefox.net.cn/forum/viewtopic.php?t=29712
以后可以自行解决



--------------------
我把你的截屏功能加到手势脚本里了

注意，修改后的脚本只有截屏一个功能
另外假定你没有其他手势脚本或扩展
否则可能出现无法预计的冲突

手势是 左右左

方向错了吧
不是在它里面加手势，是在手势里面加上截屏功能

找了个截屏脚本WebScreenShot.uc.xul
可惜在我机器上导致FF死掉……cpu占用50%，内存飙升……也没有快捷、手势之类的……
达人现身啊，呵呵
