COPY文字到剪贴板很方便,我是指在IE下面,而其他的就有点复杂了。firefox下面有安全选项的。所以很多人都采用了flash来实现。如果不计flash,那么下面这个函数就十分有用了,可能是转的过多了,也不记得来源是哪里了。如果是原作者看到,请提示一下,一定加上您的链接。
JavaScript代码
- 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'");
- }
