The example in this article describes the method of obtaining page description using js. Share it with everyone for your reference. The specific implementation method is as follows: 

var meta = pt.document.getElementsByTagName('meta');
var share_desc = '';
for(i in meta){
 if(typeof meta[i].name!="undefined"&&meta[i].name.toLowerCase()=="description"){
  share_desc = meta[i].content;
 }
}

I hope this article will be helpful to everyone’s JavaScript programming design.
