我有两个数组变量,其中每个元素都是一个具有如下属性的对象:
var employees = [{
name: 'Jack',
empId: 0,
age: 25,
orgId: 1
}, {
name: 'Lucifer',
empId: 1,
age: 35,
orgId: 2
}, {
name: 'Adam',
empId: 3,
age: 46,
orgId: 1
}, {
name: 'Eve',
empId: 4,
age: 30,
orgId: 3
}];
,第二个变量是
var companies= [{
name: 'Microsoft',
id: 1,
employees: [5 , 9]
}, {
name: 'Google',
id: 2,
employees: [1]
}, {
name: 'LinkedIn',
id: 3,
employees: [10]
}];
所以现在我希望当我提供公司名称(例如:Google)时,它会返回员工详细信息。我想通过使用filter()/ reduce()方法来做到这一点,但我无法做到这一点。需要帮助..谢谢

您可以使用forEach
循环并检查名称:
var Employees = []; //initialize
companies.forEach(function(company) {
if (company.name == "Microsoft"){
Employees = company.employees;
//whatever you like
Employees.forEach(function(id){
alert(id);
});
}
});

如果员工function unserializePhp($sessionData)
{
$returnData = array();
$offset = 0;
while ($offset < strlen($sessionData)) {
if (!strstr(substr($sessionData, $offset), '|')) {
throw new Exception('invalid data, remaining: ' . substr($sessionData, $offset));
}
$pos = strpos($sessionData, '|', $offset);
$num = $pos - $offset;
$varname = substr($sessionData, $offset, $num);
$offset += $num + 1;
$data = unserialize(substr($sessionData, $offset));
$returnData[$varname] = $data;
$offset += strlen(serialize($data));
}
return $returnData;
}
与公司orgId
相同,则可以使用filter
;一个获取id
,然后另一个获取与该ID相关联的员工。该函数返回一组员工。
id
输出
function getEmployees(company) {
var id = companies.filter(function (el) {
return el.name === company;
})[0].id;
return employee.filter(function (el) {
return el.orgId === id;
});
}
getEmployees('Microsoft');

试图提升我的技能。所以我很确定它有效,但我不知道它是否是实现你想要的好方法!
var input = "Microsoft";
for(company in companies) {
if(companies[company].name === input) {
for(emp in employee) {
if(companies[company].id === employee[emp].orgId)
{
console.log(employee[emp]);
}
}
}
}
