如何更改数组对象中的值?

Question

varstooges=[{label:1,value:1,placeCode:'sh',stock_code:40},{label:1,value:1,placeCode:'sh',stock_code:50},{label:1,value:1,placeCode:'sz',stock_code:60,status:1},{label:1,value:1,placeCode:'sz',stock_code:39,status:1}];我想将上面代码里的placeCode改变值："sh"改为"沪"，"sz"改为"深"，请问如何操作，最好用underscore.js或lodash.js

Answer 1

不用第三方库也可以实现，比较简单
varstooges=[
{label:1,value:1,placeCode:'sh',stock_code:40},
{label:1,value:1,placeCode:'sh',stock_code:50},
{label:1,value:1,placeCode:'sz',stock_code:60,status:1},
{label:1,value:1,placeCode:'sz',stock_code:39,status:1}
];
varmaps=newMap([['sh','沪'],['sz','深圳']]);
stooges=stooges.map(element=>{
element.placeCode=maps.get(element.placeCode);
returnelement;
});
console.log(stooges);
                            

Answer 2

for(vari=0;istooges[i].placeCode==='sh'?stooges[i].placeCode='沪':stooges[i].placeCode='深'
}
一个循环就搞定为啥用库来？
