在浏览器右键添加自定义菜单其实就是类似当安装完 迅雷之类的软件后 Internet Explorer 的右键多了“使用迅雷下载”的选项一样,现在我们的讲的是:当我们在图片右键时出现“复制图像地址”的选项。
其实很简单,先把下列代码存为 abc.reg 并导入注册表(在桌面上建立个记事本文件,然后把代码粘贴进去,最后把.txt扩展名改为.reg即可):
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\MenuExt\复制图像地址(&Z)]
@="C:\\CopyImageUrl.htm"
"contexts"=dword:00000002
并把下列代码存为 C:\CopyImageUrl.htm:
<script language="javascript" defer>
var Elem=external.menuArguments.event.srcElement;
var imgUrl='';
if(Elem.tagName=='IMG') imgUrl=Elem.src;
else if(Elem.tagName=='A'){
var cElem=Elem.children;
if(cElem.length){
for(i=0; i<=cElem.length-1; i++){
if(cElem[i].tagName=='IMG') imgUrl=cElem[i].src;
break;
}
}
}
if(imgUrl) clipboardData.setData('text',imgUrl)
</script>
重启你的浏览器就可以用了。
要注意几点:
这个功能适用于 IE 和所有以 IE 为内核的第三方浏览器,比如 Mathxon。
“复制图像地址(&Z)”后面的符号 Z 为快捷键,根据不冲突又易按的原则,你至少还可以改为:q、w、x。
contexts 对应应用对象有:Default、Images、Controls、Tables、Text selection、Anchor、Unknown。
与 contexts 并列的,还有一个可选的双字节 Flags,值为 0x1 时,脚本将以窗口对话框方式执行。
如果脚本存在于某 dll 文件的 123 位置,还可以用“Example.dll, 123”这样的指向来定义。
快捷键
熟练地使用这个功能,至少可以让操作快上 80% 的时间,甚至 迅雷默认也没设置这个人性化的功能,很遗憾。不过我们完全可以修改之!
可选项
Value Constant_Name Description
0x01 CONTEXT_MENU_DEFAULT Shown on all context menus.
0x02 CONTEXT_MENU_IMAGE Context menu of images only.
0x04 CONTEXT_MENU_CONTROL Context menu of form controls only.
0x08 CONTEXT_MENU_TABLE Context menu of tables only.
0x10 CONTEXT_MENU_TEXTSELECT Context menu of selected text only, including images in a selected region.
0x20 CONTEXT_MENU_ANCHOR Context menu of links only. Does not include linked images or image maps.
0x40 CONTEXT_MENU_UNKNOWN Right-click on none of the above.
多种值综合应用是“或”的关系,比如需要在默认和连接时右键时显示,则 contexts=0x21;想单独在图片上显示,则 contexts=0x02 了。
举例
下面例子可以将页面在新窗口显示:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\MenuExt\Show in New Window]
@="file://c:\\example2.htm"
"Contexts"=dword:00000001
c:\example2.htm
<SCRIPT LANGUAGE="JavaScript" defer>
window.open(external.menuArguments.location.href);
</SCRIPT>
下面例子可以将选中文字变为大写:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\MenuExt\My &Menu Item]
@="file://c:\myscript.htm"
"Contexts"=dword:00000001
c:\myscript.htm
<SCRIPT LANGUAGE="JavaScript" defer>
var parentwin = external.menuArguments;
var doc = parentwin.document;
var sel = doc.selection;
var rng = sel.createRange();
var str = new String(rng.text);
if(str.length != 0) rng.text = str.toUpperCase();
</SCRIPT>
效果
删除
将下列代码存为 unreg.reg 并导入就可以了:
Windows Registry Editor Version 5.00
[-HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\MenuExt\复制图像地址(&Z)]
