一直以为剪藏是保存的css链接+正文，然后控制台查看了剪藏的保存的正文发现他是提取元素的css样式加入style 理论上可以单独抽取样式不依赖大量的css文件，猜测浏览器有类似的函数可以提取 然后写了如下代码可以提取指定元素的css样式css选择器和id选择器元素样式 代码如下：

var obj={    "css":[],    "id":[],    "node":[]};(function(){    for(var j=0;j
    
     "+a[i].selectorText.indexOf("."));               //console.log(a[i].selectorText+"#->"+a[i].selectorText.indexOf("#"));               if(typeof(a[i].selectorText)!="undefined")               {                   try{                       if(a[i].selectorText.indexOf("#")!=-1){                           var selectorText = a[i].selectorText.replace("#","");                           var cssText = a[i].style.cssText;                           obj.id.push([selectorText,cssText]);                           //console.log(selectorText+"->"+cssText);                           continue;                       }                       if(a[i].selectorText.indexOf(".")!=-1){                           var selectorText = a[i].selectorText.replace(".","");                           var cssText = a[i].style.cssText;                           obj.css.push([selectorText,cssText]);                           //console.log(selectorText+"->"+cssText);                           continue;                       }                       var selectorText = a[i].selectorText;                       var cssText = a[i].style.cssText;                       obj.node.push([selectorText,cssText]);                       //console.log(selectorText+"->"+cssText);                       //console.log(a[i].selectorText+"->"+a[i].style.cssText);                      }catch(err){                       //console.log(err);                   }               }           }       }    } })()function GetIs(name,type){    //字符串方法indexOf    var len = obj[type].length;    for(var i=0;i
     
      =0){            return obj[type][i][1];        }    }}function GetAttr(name,type){    switch(type){        case "css":            return GetIs(name,"css");            break;        case "id":            return GetIs(name,"id");            break;        case "node":            return GetIs(name,"node");            break;     }}   function GetStyle(doc){    if(doc.id!=""){        console.log("id选择器样式->"+GetAttr(doc.id,"id"));    }    if(doc.css!=""){        console.log("css选择器样式->"+GetAttr(doc.css,"css"));    }    console.log("节点选择器样式->"+GetAttr(doc.nodeName.toLowerCase(),"node"));}console.log("css样式抽取");var a=document.getElementById("_main_body");GetStyle(a);```
