需要获取到后面的#desc，来让这个id为desc的div显示，其他某一个class隐藏
var thisId = window.location.hash;
console.log();//#desc
var thisId = window.location.hash;
thisId=thisId.substr(1,thisId.length-1);
console.log();//desc
var tpls=document.getElementsByClassName('tpls');
for (var i = 0; i<tpls.length;i++) {
tpls[i].style.display="none";
};
document.getElementById(thisId).style.display='block';
