分享一个jquery的例子,点击文本框时,复制内容到剪贴板。
代码如下:
//方法1 点击文本框复制其内容到剪贴板 function copyToClipboard(txt) { 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!"); } } //方法2 点击文本框复制其内容到剪贴板上 function setCopyLink() { $("#txt_CopyLink").val(document.URL) .focus(function () { $(this).css({ "background-color": "#ddd" }).select(); copyToClipboard($("#txt_CopyLink").val()); }).blur(function () { $(this).css({ "background-color": "#fff" }); }); }
