1、最基本的複製
Java程式碼
<script language="javascript">
function readTxt()
{
alert(window.clipboardData.getData("text"));
}
function setTxt()
{
var t=document.getElementById("txt");
t.select();
window.clipboardData.setData('text',t.createTextRange().text);
}
</script>
<input name="txt" value="測試">
<input type="button" value="複製" onclick="setTxt()">
<input type="button" value="讀取" onclick="readTxt()">
2、擴充套件複製:複製表格
Java程式碼
<INPUT TYPE="button" value="選中測試表格" onclick="CopyTable()">
測試
<TABLE border="1" id="oTable">
<TR>
<TD>測試表格</TD>
<TD>測試表格</TD>
</TR>
<TR>
<TD>測試表格</TD>
<TD>測試表格</TD>
</TR>
</TABLE>文字
<SCRIPT LANGUAGE="JavaScript">
<!--
function CopyTable()
{
var txt = document.body.createTextRange();
txt.moveToElementText(document.getElementById('oTable'));
txt.select();
}
//-->
</SCRIPT>
、相容IE,firefox等瀏覽器的複製
Java程式碼
<script>
function copyToClipboard(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) {
alert("被瀏覽器拒絕!\n請在瀏覽器位址列輸入'about:config'並回車\n然後將'signed.applets.codebase_principal_support'設定為'true'");
}
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);
}
}
</script>
<button onclick="copyToClipboard('你好!');">複製文字“你好!”</button>
<textarea id="test"></textarea>
