Java代码
<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="测试">
<input type="button" value="复制" onclick="setTxt()">
<input type="button" value="读取" onclick="readTxt()">
2、扩展复制：复制表格
Java代码
<INPUT TYPE="button" value="选中测试表格" onclick="CopyTable()">
测试
<TABLE border="1" id="oTable">
<TR>
<TD>测试表格</TD>
<TD>测试表格</TD>
</TR>
<TR>
<TD>测试表格</TD>
<TD>测试表格</TD>
</TR>
</TABLE>文字
<SCRIPT LANGUAGE="JavaScript">
<!--
function CopyTable()
{
var txt = document.body.createTextRange()
txt.moveToElementText(document.getElementById('oTable'))
txt.select()
}
//-->
</SCRIPT>
、兼容IE，firefox等浏览器的复制
Java代码
<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("被浏览器拒绝！\n请在浏览器地址栏输入'about:config'并回车\n然后将'signed.applets.codebase_principal_support'设置为'true'")
}
var clip = Components.classes['@mozilla.org/widget/clipboard1'].createInstance(Components.interfaces.nsIClipboard)
if (!clip)
return
var trans = Components.classes['@mozilla.org/widget/transferable1'].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-string1"].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！')">复制文本“你好！”</button>
<textarea id="test"></textarea>
如果你只是想实现复制id为txt的div中的文本的话：$("#cpy").click(function(){//注册复制的点击事件
alert('复制成功！')//因为根本就不用复制功能只是一个从txt_div中取值的过程
})
$("#past").click(function(){
$("textarea").val($("#txt").text())
alert('粘贴成功！')
})
