Question

假设我有一个以这种方式定义的Javascript类：

class TmpTestResult {
        constructor(id, title, testresult, tags, subsystem, info){
           this.ID = id;
           this.Title = title;
           this.TestResult = testresult;
           this.Tags = tags;
           this.Subystem = subsystem;
           this.Info = info;
}

如何在Javascript中存储TmpTestResults数组？

（我已经习惯强烈输入c＃，我对如何做到这一点感到茫然。）

我的示例数据如下所示：

function GetFakeData() {
        var fakeTestResultArray = {
            "jsonData": "",
            "listResults": [{
                "MyViewName": "Test View",
                "ID": "10233",
                "Title": "Verify the Production data is working.",
                "TestResult": "Pass",
                "Tags": "ATAB, Production, MOCK",
                "Subsystem": "TEST",
                "Info": "OK : OK"
            },
            {
                "MyViewName": "Test View",
                "ID": "54875",
                "Title": "Verify the Production data is working one more time.",
                "TestResult": "Pass",
                "Tags": "ATAB, Production, MOCK",
                "Subsystem": "TEST",
                "Info": "OK : OK"
            },
            {
                "MyViewName": "Test View",
                "ID": "87541",
                "Title": "Verify the Production data is working for a third.",
                "TestResult": "Pass",
                "Tags": "ATAB, Production, MOCK",
                "Subsystem": "TEST",
                "Info": "OK : OK"
                }],
            "MyViewName": "TEST Tests",
            "ErrorInfo": "none",
            "Count" : 0
        }

您只需使用标准数组并调用构造函数：

function GetFakeData() {
    var fakeTestResultArray = {
        "jsonData": "",
        "listResults": [
            new TmpTestResult(
                "10233", 
                "Verify the Production data is working.",
                "Pass",
                "ATAB, Production, MOCK",
                "TEST",
                "OK : OK"
            ),
            new TmpTestResult(/*...*/),
            new TmpTestResult(/*...*/),
            new TmpTestResult(/*...*/),
        ],
        "MyViewName": "TEST Tests",
        "ErrorInfo": "none",
        "Count" : 0
    }

您可能会考虑让构造函数接受一个对象（可能是可选的），因此您可以使用文字表示法：

class TmpTestResult {
    constructor(id, title, testresult, tags, subsystem, info){
       if (typeof id === "object") {
           Object.assign(this, id);
       } else {
           this.ID = id;
           this.Title = title;
           this.TestResult = testresult;
           this.Tags = tags;
           this.Subystem = subsystem;
           this.Info = info;
       }
}

然后

function GetFakeData() {
    var fakeTestResultArray = {
        "jsonData": "",
        "listResults": [
            new TmpTestResult({
                "MyViewName": "Test View",
                "ID": "10233",
                "Title": "Verify the Production data is working.",
                "TestResult": "Pass",
                "Tags": "ATAB, Production, MOCK",
                "Subsystem": "TEST",
                "Info": "OK : OK"
            }),
            new TmpTestResult({
                // ...
            }),
            // ...

JavaScript没有C＃的构造期间的属性赋值（无论它叫什么），你可以做new TmpTestResult { ID = "..." ...但是可选择接受一个对象。

您可以使用.map并返回TmpTestResult对象，例如

fakeTestResultArray.listResults.map(o => new TmpTestResult(o.ID, o.Title, o.TestResult, o.Tags, o.Subsystem, o.Info));

这是片段

class TmpTestResult {
    constructor(id, title, testresult, tags, subsystem, info) {
        this.ID = id;
        this.Title = title;
        this.TestResult = testresult;
        this.Tags = tags;
        this.Subystem = subsystem;
        this.Info = info;
    }
}
var fakeTestResultArray = {
    "jsonData": "",
    "listResults": [{
            "MyViewName": "Test View",
            "ID": "10233",
            "Title": "Verify the Production data is working.",
            "TestResult": "Pass",
            "Tags": "ATAB, Production, MOCK",
            "Subsystem": "TEST",
            "Info": "OK : OK"
        },
        {
            "MyViewName": "Test View",
            "ID": "54875",
            "Title": "Verify the Production data is working one more time.",
            "TestResult": "Pass",
            "Tags": "ATAB, Production, MOCK",
            "Subsystem": "TEST",
            "Info": "OK : OK"
        },
        {
            "MyViewName": "Test View",
            "ID": "87541",
            "Title": "Verify the Production data is working for a third.",
            "TestResult": "Pass",
            "Tags": "ATAB, Production, MOCK",
            "Subsystem": "TEST",
            "Info": "OK : OK"
        }
    ],
    "MyViewName": "TEST Tests",
    "ErrorInfo": "none",
    "Count": 0
}



var res = fakeTestResultArray.listResults.map(o => new TmpTestResult(o.ID, o.Title, o.TestResult, o.Tags, o.Subsystem, o.Info));

console.log(res)

在JavaScript中，一切都是基本类型，如字符串或数字，或数组[]或对象{}。将数据存储在可以具有嵌套对象的对象数组中。基本上，fakeTestResultArray已经做得很好。

现在你应该找一个可以保存JSON对象的数据库。像MongoDB这样的东西。

如何在Javascript中存储特定类的对象数组？
