请问如何在服务器返回的数据中提取出我需要的那部分
以下是服务器返回的数据
[{
"procDef.name": "请假流程",
"task.assignee": "admin",
"task.executionId": "a25a1287decc4aea97fda5c8c4a49e4a",

},
"status": "todo"
}, {
"procDef.name": "请假流程",
"task.assignee": "admin",
"task.executionId": "e8065adf4db344fc92165c732ed85156",

}, {

"node0Pass": true,

"type": "tealeave",
"applyUserId": "李三"
}]
我只需要这些数据中几项
"procDef.name"，"task.name","task.createTime",还有"vars"中的"applyUserId"
放入我下面的数据中：
info: [{
"proccessname": "请假",
"curretprocess": "领导审核",
"createTime": 1557399272000,
"applyUserId": "张xx"
}]
直接赋值会有问题 比如proccessname=list[0].procDef.name 后面的name会报错说undefined ，请问如何处理
另外 proccessname 只有前个字 比如'请假流程'只留'请假'2字
createTime时间戳转换到年-月-日格式
谢谢 新手真不太会
var src=你的数据
var desc=[];//你要的数据
src.forEach((data)=>{
desc.push({
"proccessname": data["procDef.name"].substring(0,2),
"curretprocess": data["task.name"],
"createTime": new Date(parseInt(data["task.createTime"])).toUTCString(),
"applyUserId": data["vars"]["applyUserId"]
});
});
最终的desc：
[
{
"proccessname":"请假",
"curretprocess":"领导审核",
"createTime":"Thu, 23 May 2019 10:55:17 GMT",
"applyUserId":"张大壮"
},
{
"proccessname":"请假",
"curretprocess":"领导审核",
"createTime":"Thu, 09 May 2019 10:54:32 GMT",
"applyUserId":"lilaoshi"
},
{
"proccessname":"请假",
"curretprocess":"领导审核",
"createTime":"Thu, 09 May 2019 09:09:41 GMT",
"applyUserId":"李三"
}
]
获取到数据后处理：
var list = 你获取的数据列表；
var newlist = []; // 新的数据列表
for (var i = 0; i < list.length; i++) {
var singledata = {
"proccessname": list[i].procDef.name,
"curretprocess": list[i].task.name,
"createTime": list[i].task.createTime,
"applyUserId": list[i].vars.applyUserId,
}
newlist.push(singledata);
}
得到的newlist就是你想要的数据，大概思路就是这样。
另外 proccessname 只有前个字 time还能转换到正常格式 , 这个我是这没看懂。
