我的问题是关于以下功能：
function loadConfigurations(configs){
console.log(configs);
}
loadConfigurations函数接收的“ configs”对象包含两个属性-两个数组，一个称为“ assigned”，另一个称为“ unssigned”。执行console.log（configs）输出以下内容：
"Object{assigned: Array[5], unassigned: Array[1]}"
现在，我想枚举“分配”数组和“未分配数组”中每个属性的键值对。
configs对象的结构如下：
抱歉，伙计们。这是configs对象的结构：
var configs = {
"config1":
{
"assigned": [
{
"name": "Admin Usersss",
"value": "admin-user"
},
{
"name": "MPR User",
"value": "mpr-user"
},
{
"name": "SAMHSA User",
"value": "samhsa-user"
}
],
"unassigned": [
{
"name": "States User",
"value": "states-user"
},
{
"name": "All States User",
"value": "all-states-user"
},
{
"name": "Substance Abuse User",
"value": "substance-abuse-user"
}
]
},
"config2":
{
"assigned": [
{
"name": "Admin User",
"value": "admin-user"
},
{
"name": "MPR User",
"value": "mpr-user"
},
{
"name": "SAMHSA User",
"value": "samhsa-user"
},
{
"name": "States User",
"value": "states-user"
},
{
"name": "All States User",
"value": "all-states-user"
}
],
"unassigned": [
{
"name": "Substance Abuse User",
"value": "substance-abuse-user"
}
]
},
"config3":
{
"assigned": [
{
"name": "Admin User",
"value": "admin-user"
}
],
"unassigned": [
{
"name": "States User",
"value": "states-user"
},
{
"name": "All States User",
"value": "all-states-user"
},
{
"name": "Substance Abuse User",
"value": "substance-abuse-user"
},
{
"name": "MPR User",
"value": "mpr-user"
},
{
"name": "SAMHSA User",
"value": "samhsa-user"
}
]
}
我该怎么做呢？
谢谢，CM
给定您发布的数据结构，您可以使用Object.keys()它枚举父对象的键，然后在其中的assigned和unassigned属性上循环。试试这个：
Object.keys(configs).forEach(function(key) {
var config = configs[key];
config.assigned.forEach(function(assigned) {
console.log('A: ' + assigned.name + ', ' + assigned.value);
});
config.unassigned.forEach(function(assigned) {
console.log('U: ' + assigned.name + ', ' + assigned.value);
});
})
var configs = {
"config1": {
"assigned": [{
"name": "Admin Usersss",
"value": "admin-user"
}, {
"name": "MPR User",
"value": "mpr-user"
}, {
"name": "SAMHSA User",
"value": "samhsa-user"
}],
"unassigned": [{
"name": "States User",
"value": "states-user"
}, {
"name": "All States User",
"value": "all-states-user"
}, {
"name": "Substance Abuse User",
"value": "substance-abuse-user"
}]
},
"config2": {
"assigned": [{
"name": "Admin User",
"value": "admin-user"
}, {
"name": "MPR User",
"value": "mpr-user"
}, {
"name": "SAMHSA User",
"value": "samhsa-user"
}, {
"name": "States User",
"value": "states-user"
}, {
"name": "All States User",
"value": "all-states-user"
}],
"unassigned": [{
"name": "Substance Abuse User",
"value": "substance-abuse-user"
}]
},
"config3": {
"assigned": [{
"name": "Admin User",
"value": "admin-user"
}],
"unassigned": [{
"name": "States User",
"value": "states-user"
}, {
"name": "All States User",
"value": "all-states-user"
}, {
"name": "Substance Abuse User",
"value": "substance-abuse-user"
}, {
"name": "MPR User",
"value": "mpr-user"
}, {
"name": "SAMHSA User",
"value": "samhsa-user"
}]
}
}
Object.keys(configs).forEach(function(key) {
var config = configs[key];
config.assigned.forEach(function(assigned) {
console.log(key + ' A: ' + assigned.name + ', ' + assigned.value);
});
config.unassigned.forEach(function(assigned) {
console.log(key + ' U: ' + assigned.name + ', ' + assigned.value);
});
})还要注意的是（在评论尖的由@adeneo了你的问题），如果您正在执行两个相同的逻辑assigned和unassigned项目，那么你可以再在一起，将它们串联和迭代他们。
如果属性之间的逻辑不同，则需要上述方法。
