我有一个学校项目,当JSON格式不同时,我必须创建一个“ if else”语句以使用不同的变量。
下面是我要提取并用作车把的有效载荷:
"templateName": "xyzTemplate",
"payload": {
"categories": "chocolates",
"modifier": "chocolate-detail",
"header": "Your Chocolates",
"channelType": "W",
"accounts": [{
"subTitle": "Sorry, I am having trouble processing your current request.",
"acctId": "I love chocolates",
"type": "Dark Chocolates",
"extraParams": {
"amountOfChocolates": "4386249702964395",
"chocolatesEaten": "27000"
但是,有时有效载荷会变成这样:
"templateName": "xyzTemplate",
"payload": {
"categories": "chocolates",
"modifier": "chocolate-detail",
"header": "Your Chocolates",
"channelType": "W",
"accounts": [
{
"subTitle": "Sorry, I am having trouble processing your current request.",
"acctId": "I love chocolates",
"account": {
"type": "Dark Chocolates",
"extraParams": {
"amountOfChocolates": "4386249702964395",
"chocolatesEaten": "27000"
},
我想使用以下变量var数据来反映不同的有效负载。示例:
var alldata = [];
//if payload has accounts[0].account
var data = var data = resp.payload.accounts[0].account;
//else
var data = resp.payload.accounts[0];
非常感谢您对此提供的帮助。
答案 0 :(得分:-2)
如果我正确理解了这个问题: 使用“ sub”帐户道具(如果有),否则使用帐户?
const account = resp.payload.accounts[0];
const data = account.account || account;
注意:首选使用'const'和'let'而不是'var'。 (但是您稍后可能会在编程类中看到它:D)
