我想根据薪水使用 if 条件修改数组答案

【问题标题】：I want to modify an array using if condition according to salary我想根据薪水使用 if 条件修改数组
【发布时间】：2019-09-10 17:38:54
【问题描述】：

我希望修改从 api 获得的数组并添加新密钥：Salary。

条件是：

年龄小于等于23：薪水为23,000
23岁以上27岁以下：工资27000元
27岁以上：年薪50万

这是数组：

var employee=[
  {
    "firstName": "Zahir",
    "lastName": "Alam",
    "Age": 25,
    "Company": "Switchme",
    "Role": "Developer",
    "Department": "Tech",
    "Head": {
      "Id": 3,
      "Name": "Sourasis Roy"
    }
  }, {
    "firstName": "Amith",
    "lastName": "Manniken",
    "Age": 25,
    "Company": "Switchme",
    "Role": "Developer",
    "Department": "Tech",
    "Head": {
      "Id": 3,
      "Name": "Sourasis Roy"
    }
  }, {
    "firstName": "Sourasis",
    "lastName": "Roy",
    "Age": 28,
    "Company": "Switchme",
    "Role": "CTO"
  }, {
    "firstName": "Aditya",
    "lastName": "Mishra",
    "Age": 29,
    "Company": "Switchme",
    "Department": "Tech",
    "Role": "CEO"
  }, {
    "firstName": "Priti",
    "lastName": "Lata",
    "Age": 24,
    "Company": "Switchme",
    "Role": "HR"
  }, {
    "firstName": "Sumita",
    "lastName": "Nath",
    "Age": 24,
    "Company": "Switchme",
    "Role": "HLA Head",
    "Department": "Crm"
  }, {
    "firstName": "Tarini",
    "lastName": "Khanna",
    "Age": 22,
    "Company": "Switchme",
    "Role": "Content Writer"
  }, {
    "firstName": "Abhisek",
    "lastName": "Soni",
    "Age": 23,
    "Company": "Switchme",
    "Role": "HLA",
    "Department": "Crm",
    "Head": {
      "Id": 5,
      "Name": "Sumita Nath"
    }
  }, {
    "firstName": "Ankit",
    "lastName": "Pump",
    "Age": 23,
    "Company": "Switchme",
    "Role": "HLA",
    "Department": "Crm",
    "Head": {
      "Id": 5,
      "Name": "Sumita Nath"
    }
  }, {
    "firstName": "Pogo",
    "lastName": "Laal",
    "Age": 23,
    "Company": "Switchme",
    "Role": "Designer"
  }, {
    "firstName": "Sabina",
    "lastName": "Sekh",
    "Age": 28,
    "Company": "Switchme",
    "Role": "HLA Head",
    "Department": "Crm"
  }, {
    "firstName": "Sanjay",
    "lastName": "Poudal",
    "Age": 24,
    "Company": "Switchme",
    "Role": "HLA Head",
    "Department": "Crm",
    "Head": {
      "Id": 10,
      "Name": "Sabina Sekh"
    }
  }
];

这是我的代码：

$(document).ready(function(){
  $.each( employee, function( key, value ) {
    if(value["Age"] <= 23) {
      var obj = {};
      obj[Salary] = 23000;
      employee.push(obj);
    }
    else if(value["Age"] > 23 && value["Age"] < 27) {
      var obj2 = {};
      obj2[Salary] = 27000;
      employee.push(obj2);
    }
    else if(value["Age"] > 27) {
      var obj3 = {};
      obj3[Salary] = 500000;
      employee.push(obj3);
    } 
  });
  $.each(employee, function(index, value){
    $("#modfy").append(index + ": " + value + '<br>');
  });
});

我的 HTML：

<div class="modfy"></div>

【解决方案1】：

只需将属性 Salary 添加到对象，不要忘记使用 id 而不是 class。

var employee = [{
  "firstName": "Zahir",
  "lastName": "Alam",
  "Age": 25,
  "Company": "Switchme",
  "Role": "Developer",
  "Department": "Tech",
  "Head": {
    "Id": 3,
    "Name": "Sourasis Roy"
  }
}, {
  "firstName": "Amith",
  "lastName": "Manniken",
  "Age": 25,
  "Company": "Switchme",
  "Role": "Developer",
  "Department": "Tech",
  "Head": {
    "Id": 3,
    "Name": "Sourasis Roy"
  }
}, {
  "firstName": "Sourasis",
  "lastName": "Roy",
  "Age": 28,
  "Company": "Switchme",
  "Role": "CTO"
}, {
  "firstName": "Aditya",
  "lastName": "Mishra",

最终输出应该是前一个数组中的所有内容加上薪水对象
谢谢你，我会做相应的。谢谢你的帮助
就是这样，同一个数组，同一个对象，只是添加了一个属性薪水和类的错误而不是id选择器
不，但不是整个数组都没有打印。请问您可以相应地进行更改吗？
我想要像 [ { "firstName":"Zahir", "lastName":"Alam", "Age":25, "Company":"Switchme", "Role":"Developer ", "部门":"技术", "负责人":{ "Id":3, "姓名":"Sourasis Roy" }, "薪水":"27,000" }, { "firstName":"Amith", " lastName":"Manniken", "Age":25, "Company":"Switchme", "Role":"Developer", "Department":"Tech", "Head":{ "Id":3, "Name ":"Sourasis Roy" }, "Salary":"27,000" }, { "firstName":"Sourasis", "lastName":"Roy", "Age":28, "Company":"Switchme", "Role ":"CTO", "薪水":"500,000" } ]

【解决方案2】：

您不需要创建新对象，只需在每个循环中为值对象添加属性。其他问题：

您输入了class="modify"，但将其用作 id #modify。而每一个循环，都需要使用值作为对象。

 $(".modfy").append(++index + ". " + value.firstName + ": " + value.lastName + ": " + value.Age + ": " + value.Company + ": " + value.Role + ": " + value.Department + ": " + value.Salary + '<br>');

如果您想按要求打印每个对象，只需要$(".modfy").append(JSON.stringify(value));

或其他方式，如果您想显示为数组$(".modfy").append(JSON.stringify(employee));

$(document).ready(function(){
    $.each( employee, function( key, value ) {
        if(value["Age"] <= 23) {
        //var obj = {};
        value["Salary"] = 23000;
        //employee.push(obj);
        }
        else if(value["Age"] > 23 && value["Age"] < 27) {
        //var obj2 = {};
        value["Salary"] = 27000;
        //employee.push(obj2);
        }
        else if(value["Age"] > 27) {
        //var obj3 = {};
        value["Salary"] = 500000;
        //employee.push(obj3);
        } 
    });

var employee=[{"firstName":"Zahir","lastName":"Alam","Age":25,"Company":"Switchme","Role":"Developer","Department":"Tech","Head":{"Id":3,"Name":"Sourasis Roy"}},{"firstName":"Amith","lastName":"Manniken","Age":25,"Company":"Switchme","Role":"Developer","Department":"Tech","Head":{"Id":3,"Name":"Sourasis Roy"}},{"firstName":"Sourasis","lastName":"Roy","Age":28,"Company":"Switchme","Role":"CTO"},{"firstName":"Aditya","lastName":"Mishra","Age":29,"Company":"Switchme","Department":"Tech","Role":"CEO"},{"firstName":"Priti","lastName":"Lata","Age":24,"Company":"Switchme","Role":"HR"},{"firstName":"Sumita","lastName":"Nath","Age":24,"Company":"Switchme","Role":"HLA Head","Department":"Crm"},{"firstName":"Tarini","lastName":"Khanna","Age":22,"Company":"Switchme","Role":"Content Writer"},{"firstName":"Abhisek","lastName":"Soni","Age":23,"Company":"Switchme","Role":"HLA","Department":"Crm","Head":{"Id":5,"Name":"Sumita Nath"}},{"firstName":"Ankit","lastName":"Pump","Age":23,"Company":"Switchme","Role":"HLA","Department":"Crm","Head":{"Id":5,"Name":"Sumita Nath"}},{"firstName":"Pogo","lastName":"Laal","Age":23,"Company":"Switchme","Role":"Designer"},{"firstName":"Sabina","lastName":"Sekh","Age":28,"Company":"Switchme","Role":"HLA Head","Department":"Crm"},{"firstName":"Sanjay","lastName":"Poudal","Age":24,"Company":"Switchme","Role":"HLA Head","Department":"Crm","Head":{"Id":10,"Name":"Sabina Sekh"}}];

$(document).ready(function(){
    $.each( employee, function( key, value ) {
        if(value["Age"] <= 23) {
        //var obj = {};
        value["Salary"] = 23000;
        //employee.push(obj);
        }
        else if(value["Age"] > 23 && value["Age"] < 27) {
        //var obj2 = {};
        value["Salary"] = 27000;
        //employee.push(obj2);
        }
        else if(value["Age"] > 27) {
        //var obj3 = {};
        value["Salary"] = 500000;
        //employee.push(obj3);
        } 
    });
    //console.log(employee)
   // $.each(employee, function(index, value){

【讨论】：

还有一个错误，他需要把class=改成id=否则不行。
我将其更改为 id 然后即使输出不正确...其显示为 0: [object Object]
我更新了代码，你需要使用值对象的属性
如果我想打印整个数组怎么办？
我想要像 [ { "firstName":"Zahir", "lastName":"Alam", "Age":25, "Company":"Switchme", "Role":"Developer ", "部门":"技术", "负责人":{ "Id":3, "姓名":"Sourasis Roy" }, "薪水":"27,000" }, { "firstName":"Amith", " lastName":"Manniken", "Age":25, "Company":"Switchme", "Role":"Developer", "Department":"Tech", "Head":{ "Id":3, "Name ":"Sourasis Roy" }, "Salary":"27,000" }, { "firstName":"Sourasis", "lastName":"Roy", "Age":28, "Company":"Switchme", "Role ":"CTO", "薪水":"500,000" } ]
