我试图弄清楚如何使用 Javascript 将这个 JSON 响应中的 id 值 817457 更改为另一个值，特别是 999999。有什么帮助吗？

var getresponse = [{"messages":[],"entity":{"id":817457,"name":"Test 1","campaignId":119602,"startDate":1528848000000,"endDate":1546300740000,"optimizationGoal":"CPM","lifetimeBudget":20.0,"audiences":[{"id":1026692,"name":"Default Audience","pmpDeals":null,"siteLists":null,"exchanges":{"include":[5,45],"exclude":[]}}],"max_bid":2.0,"daily_budget":null,"channels":["DESKTOP","MOBILE"]}}]

【问题讨论】：

getresponse[0].entity.id = 999999.

【解决方案1】：

getresponse 是一个对象，而不是 JSON 字符串，因此您只需更新值即可。

var getresponse = [{"messages":[],"entity":{"id":817457,"name":"Test 1","campaignId":119602,"startDate":1528848000000,"endDate":1546300740000,"optimizationGoal":"CPM","lifetimeBudget":20.0,"audiences":[{"id":1026692,"name":"Default Audience","pmpDeals":null,"siteLists":null,"exchanges":{"include":[5,45],"exclude":[]}}],"max_bid":2.0,"daily_budget":null,"channels":["DESKTOP","MOBILE"]}}]
getresponse[0].entity.id = 999999

如果是 JSON 字符串，您可以执行以下操作：

var decoded = JSON.parse(getresponse)
decoded[0].entity.id = 999999
var encoded = JSON.stringify(decoded)
