Find JSON value based on Max date in another field

问题

Sure, here's the translated code snippet without the request for translation:

var jsonData = JSON.parse(responseBody);

var maxDate = null;
var experimentId = null;

for (var i = 0; i < jsonData.length; i++) {
  var createdDate = new Date(jsonData[i]["CreatedDate"]);

  if (maxDate === null || createdDate > maxDate) {
    maxDate = createdDate;
    experimentId = jsonData[i]["ExperimentId"];
  }
}

postman.setEnvironmentVariable("maxCreatedDateExperimentId", experimentId);

This code will find the maximum CreatedDate from your JSON response and store the associated ExperimentId in a Postman environment variable named maxCreatedDateExperimentId.

英文:

I have a JSON response body that looks like this:

[
    {
        &quot;ExperimentPlanningId&quot;: 20,
        &quot;ExperimentId&quot;: &quot;PT1011&quot;,
        &quot;AnalystId&quot;: 2,
        &quot;ExperimentTemplateId&quot;: 1,
        &quot;NumberoFPools&quot;: null,
        &quot;ExperimentStatus&quot;: &quot;InProgress&quot;,
        &quot;NextProcess&quot;: &quot;234343&quot;,
        &quot;CurrentProcess&quot;: &quot;Test Process 1&quot;,
        &quot;NextStage&quot;: &quot;Stage 1 2&quot;,
        &quot;CurrentStage&quot;: &quot;Stage 1 2&quot;,
        &quot;NextProcessStartDate&quot;: &quot;2022-10-15T14:00:00+00:00&quot;,
        &quot;CurrentProcessEndDate&quot;: &quot;2022-10-15T14:00:00+00:00&quot;,
        &quot;ExperimentStartDate&quot;: &quot;2022-10-14T15:00:00+00:00&quot;,
        &quot;ProjectedOutcome&quot;: null,
        &quot;ExperimentalDesign&quot;: null,
        &quot;IsActive&quot;: true,
        &quot;CreatedDate&quot;: &quot;2022-10-14T20:10:42.8276862+00:00&quot;
		
	},
	{
	    &quot;ExperimentPlanningId&quot;: 20,
        &quot;ExperimentId&quot;: &quot;JD2994&quot;,
        &quot;AnalystId&quot;: 2,
        &quot;ExperimentTemplateId&quot;: 1,
        &quot;NumberoFPools&quot;: null,
        &quot;ExperimentStatus&quot;: &quot;InProgress&quot;,
        &quot;NextProcess&quot;: &quot;234343&quot;,
        &quot;CurrentProcess&quot;: &quot;Test Process 1&quot;,
        &quot;NextStage&quot;: &quot;Stage 1 2&quot;,
        &quot;CurrentStage&quot;: &quot;Stage 1 2&quot;,
        &quot;NextProcessStartDate&quot;: &quot;2022-10-15T14:00:00+00:00&quot;,
        &quot;CurrentProcessEndDate&quot;: &quot;2022-10-15T14:00:00+00:00&quot;,
        &quot;ExperimentStartDate&quot;: &quot;2022-10-14T15:00:00+00:00&quot;,
        &quot;ProjectedOutcome&quot;: null,
        &quot;ExperimentalDesign&quot;: null,
        &quot;IsActive&quot;: true,
        &quot;CreatedDate&quot;: &quot;2023-03-31T16:23:19.5981913+00:00&quot;
	}
]

I want to loop through the response body in Postman, find the MAX CreatedDate and store the ExperimentId associated with it, in a variable. So in the example above I'd want to store JD2994 in a variable.

I started with this, but am getting a max is not defined error:

var jsonData = JSON.parse(responseBody)

for (var i=0, len = jsonData.length; i&lt;len; i++) {
  var value = max(jsonData[i][&quot;CreatedDate&quot;]);
}

以下是翻译好的内容：

Here is a better loop
这是一个更好的循环

let maxDate = 0;
let maxId = "";
data.forEach(({ CreatedDate, ExperimentId }) => {
  const d = new Date(CreatedDate).getTime();
  if (d > maxDate) {
    maxId = ExperimentId;
    maxDate = d;
  }
})
console.log(new Date(maxDate), maxId)

Reduce:
简化：

const maxId = data.reduce((savedMax, { CreatedDate, ExperimentId }) => {
  if (CreatedDate > savedMax.date) { // 日期格式可以进行字符串比较
    savedMax.date = CreatedDate;
    savedMax.id = ExperimentId;
  }
  return savedMax;
}, { date: "", id: "" }); // 初始化 savedMax
console.log(maxId);
