点击复制内容到剪贴板

if (document.all) {//ie浏览器
$("#copyLink").click(function(){
window.clipboardData.setData("text",$("#register_link").val())
alert("邀请链接地址复制成功，你可以直接复制发给你的好友!");
});
} else {//非ie
$("#copyLink").zclip({  
            path:'http://img3.job1001.com/js/ZeroClipboard/ZeroClipboard.swf',  
            copy:function(){return $("#register_link").val();},  
            afterCopy:function(){alert('邀请链接地址复制成功，你可以直接复制发给你的好友!');}  
        });
}

非ie浏览器需要借助jquery.zclip.min.js
