Question

drawerList:[{url:'../../static/images/icon/coin-etc.png',name:'ETC',zhangfu:+122.33,price:228.253,about:3.3248,state:1},{url:'../../static/images/icon/coin-bat.png',name:'BAT',zhangfu:-12.20,price:68.53,about:3.3248,state:0},{url:'../../static/images/icon/coin-gram.png',name:'GRA',zhangfu:+121.13,price:68.3223022,about:3.3248,state:1},{url:'../../static/images/icon/coin-eth.png',name:'ETH',zhangfu:+12.83,price:68.25232,about:3.3248,state:1},{url:'../../static/images/icon/coin-bat.png',name:'BAT',zhangfu:-122.03,price:12.25322232,about:3.3248,state:0},{url:'../../static/images/icon/coin-etc.png',name:'ETC',zhangfu:-12.13,price:68.253232,about:3.3248,state:0},{url:'../../static/images/icon/coin-bat.png',name:'BAT',zhangfu:-9.03,price:68.253232,about:3.3248,state:0},],我想分别在click事件中，根据zhangfu字段做从大到小和从小到大对数组做排序请问，这个js方法应该怎么写？我尝试了几种写法，好像都不太对

functionsortList(a,b){
returnb.zhangfu-a.zhangfu
}
drawerList.sort(sortList)
console.log(drawerList)

//记得不要污染源数据
letarr=obj.drawerList.concat();
//升序
arr.sort(function(i,j){
returni.zhangfu-j.zhangfu
})
