像百度文库这样的网站不总有对网页功能的限制嘛，就比如复制上面的文字，这个估计很多人都遇到过。
今天这个方法就是新建一个书签，没错，书签不光是可以用来收藏那些吃灰的教程，也可以当脚本来用。加上一串JS代码，就可以绕过网站限制来实现复制功能。
操作更简单，在需要复制文字的时候点一下它，就可以破除限制，复制文字了。
复制好下面代码，添加为浏览器的书签：
javascript:(function(bookmarklets)%7Bfor(var%20i=0;i%3Cbookmarklets.length;i++)%7Bvar%20code=bookmarklets%5Bi%5D.url;if(code.indexOf(%22javascript:%22)!=-1)%7Bcode=code.replace(%22javascript:%22,%22%22);eval(code)%7Delse%7Bcode=code.replace(/%5Es+%7Cs+$/g,%22%22);if(code.length%3E0)%7Bwindow.open(code)%7D%7D%7D%7D)(%5B%7Btitle:%22%E7%A0%B4%E9%99%A4%E5%8F%B3%E9%94%AE%E8%8F%9C%E5%8D%95%E9%99%90%E5%88%B6%22,url:%22javascript:function%20applyWin(a)%7Bif(typeof%20a.__nnANTImm__===%5Cx22undefined%5Cx22)%7Ba.__nnANTImm__=%7B%7D;a.__nnANTImm__.evts=%5B%5Cx22mousedown%5Cx22,%5Cx22mousemove%5Cx22,%5Cx22copy%5Cx22,%5Cx22contextmenu%5Cx22%5D;a.__nnANTImm__.initANTI=function()%7Ba.__nnantiflag__=true;a.__nnANTImm__.evts.forEach(function(c,b,d)%7Ba.addEventListener(c,this.fnANTI,true)%7D,a.__nnANTImm__)%7D;a.__nnANTImm__.clearANTI=function()%7Bdelete%20a.__nnantiflag__;a.__nnANTImm__.evts.forEach(function(c,b,d)%7Ba.removeEventListener(c,this.fnANTI,true)%7D,a.__nnANTImm__);delete%20a.__nnANTImm__%7D;a.__nnANTImm__.fnANTI=function(b)%7Bb.stopPropagation();return%20true%7D;a.addEventListener(%5Cx22unload%5Cx22,function(b)%7Ba.removeEventListener(%5Cx22unload%5Cx22,arguments.callee,false);if(a.__nnantiflag__===true)%7Ba.__nnANTImm__.clearANTI()%7D%7D,false)%7Da.__nnantiflag__===true?a.__nnANTImm__.clearANTI():a.__nnANTImm__.initANTI()%7DapplyWin(top);var%20fs=top.document.querySelectorAll(%5Cx22frame,%20iframe%5Cx22);for(var%20i=0,len=fs.length;i%3Clen;i++)%7Bvar%20win=fs%5Bi%5D.contentWindow;try%7Bwin.document%7Dcatch(ex)%7Bcontinue%7DapplyWin(fs%5Bi%5D.contentWindow)%7D;void%200;%22%7D,%7Btitle:%22%E7%A0%B4%E9%99%A4%E9%80%89%E6%8B%A9%E5%A4%8D%E5%88%B6%E9%99%90%E5%88%B6%22,url:%22javascript:(function()%7Bvar%20doc=document;var%20bd=doc.body;bd.onselectstart=bd.oncopy=bd.onpaste=bd.onkeydown=bd.oncontextmenu=bd.onmousemove=bd.onselectstart=bd.ondragstart=doc.onselectstart=doc.oncopy=doc.onpaste=doc.onkeydown=doc.oncontextmenu=null;doc.onselectstart=doc.oncontextmenu=doc.onmousedown=doc.onkeydown=function%20()%7Breturn%20true;%7D;with(document.wrappedJSObject%7C%7Cdocument)%7Bonmouseup=null;onmousedown=null;oncontextmenu=null;%7Dvar%20arAllElements=document.getElementsByTagName(%5Cx27*%5Cx27);for(var%20i=arAllElements.length-1;i%3E=0;i--)%7Bvar%20elmOne=arAllElements;with(elmOne.wrappedJSObject%7C%7CelmOne)%7Bonmouseup=null;onmousedown=null;%7D%7Dvar%20head=document.getElementsByTagName(%5Cx27head%5Cx27)%5B0%5D;if(head)%7Bvar%20style=document.createElement(%5Cx27style%5Cx27);style.type=%5Cx27text/css%5Cx27;style.innerHTML=%5Cx22html,*%7B-moz-user-select:auto!important;%7D%5Cx22;head.appendChild(style);%7Dvoid(0);%7D)();%22%7D%5D)这样就可以了，以后再有遇到有复制文字限制，点一下这个小书签就可以了。
