这篇文章主要介绍了JS将制定内容复制到剪切板的方法,需要的朋友可以参考下

 代码如下: function copyText() {    //复制内容  var txt = document.getElementById("table2").rows[1].cells[0].innerHTML;    //去除空格  txt = txt.replace(/ /," ");    //去除换行  txt = txt.replace(/<BR><BR>/," ");  if (window.clipboardData) {  window.clipboardData.clearData();  window.clipboardData.setData("Text", txt);  alert("已经成功复制到剪帖板上！");  }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/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);  alert("已经成功复制到剪帖板上！");  }  }
