1.打印页面的所有脚本引用文件及代码段：
javascript:var scriptarray=document.getElementsByTagName("script");for(scriptindex in scriptarray){console.log(scriptarray[scriptindex])};
2.解除页面不能选择、拷贝文字：
javascript:document.getElementsByTagName("body")[0].onselectstart=function(){};document.getElementsByTagName("body")[0].oncontextmenu=function(){};
3.显示页面元素的事件处理函数：
javascript:(function()%20{var%20protocol%20=%20window.location.protocol%20===%20'file:'%20?'http:'%20:%20'';var%20url%20=%20protocol+'//www.sprymedia.co.uk/VisualEvent/VisualEvent_Loader.js';if(%20typeof%20VisualEvent!='undefined'%20)%20{if%20(%20VisualEvent.instance%20!==%20null%20)%20{VisualEvent.close();}else%20{new%20VisualEvent();}}else%20{var%20n=document.createElement('script');n.setAttribute('language','JavaScript');n.setAttribute('src',url+'?rand='+new%20Date().getTime());document.body.appendChild(n);}})();
后面，会继续添加更多有用的，常用的小脚本
