Support clipboard operation code for IE and FireFox_javascript skills

复制代码 代码如下:

Firefox/3.0.14下可以运行

Firefox/3.5.3下无效

不过多考虑这一块了。

下面是ie firefox 读取剪切板中的信息的方法

复制代码 代码如下:

function getClipboard()
{
if (window.clipboardData)
{
return (window.clipboardData.getData('text'));
}
else
{
if (window.netscape)
{
try
{
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
var clip = Components.classes["@mozilla.org/widget/clipboard;1"].createInstance(Components.interfaces.nsIClipboard);
if (!clip)
{
return;
}
var trans = Components.classes["@mozilla.org/widget/transferable;1"].createInstance(Components.interfaces.nsITransferable);
if (!trans)
{
return;
}
trans.addDataFlavor("text/unicode");
clip.getData(trans, clip.kGlobalClipboard);
var str = new Object();
var len = new Object();
trans.getTransferData("text/unicode", str, len);
}
catch (e)
{
alert("您的firefox安全限制限制您进行剪贴板操作，请打开'about:config'将signed.applets.codebase_principal_support'设置为true'之后重试，相对路径为firefox根目录/greprefs/all.js");
return null;
}
if (str)
{
if (Components.interfaces.nsISupportsWString)
{
str = str.value.QueryInterface(Components.interfaces.nsISupportsWString);
}
else
{
if (Components.interfaces.nsISupportsString)
{
str = str.value.QueryInterface(Components.interfaces.nsISupportsString);
}
else
{
str = null;
}
}
}
if (str)
{
return (str.data.substring(0, len.value / 2));
}
}
}
return null;
}

下面是 ie,firefox下 写入剪切板的代码

复制代码 代码如下:

copy2Clipboard=function(txt){
if(window.clipboardData){
window.clipboardData.clearData();
window.clipboardData.setData("Text",txt);
}
else if(navigator.userAgent.indexOf("Opera")!=-1){
window.location=txt;
}
else if(window.netscape){
try{
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
catch(e){
your fire alert(" Fox security restrictions limit your clipboard operations , please open 'about:config' and set signed.applets.codebase_principal_support' to true' and try again. The relative path is the firefox root directory/greprefs/all.js"); > var clip=Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);
if(!clip)return;
var trans=Components.classes ['@mozilla.org/widget/transferable;1'].createInstance(Components.interfaces.nsITransferable);
if(!trans)return;
trans.addDataFlavor('text/unicode');
var str=new Object();
var len=new Object();
var str=Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces. nsISupportsString);
var copytext=txt;str.data=copytext;
trans.setTransferData("text/unicode",str,copytext.length*2);
var clipid=Components.interfaces.nsIClipboard ;
if(!clip)return false;
clip.setData(trans,null,clipid.kGlobalClipboard);
}
}
