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);
