我具有以下功能:
populateClinicRoomSelect(object) {
var selectArray = [];
var options = [];
for(var key in object) {
if(object.hasOwnProperty(key)) {
options = {
value: object[key].id,
label: object[key].RoomName,
};
selectArray = selectArray.concat(options);
}
}
return selectArray;
}
这个想法是从对象数组中获取两个已定义的字段,并将其放置在新数组中。工作正常。除了“ id”字段和“ RoomName”字段是不同的字段名称外,我还有其他一些功能完全相同。有什么方法可以将“ id”和“ RoomName”作为函数变量来在函数中定义它们?

当然,您可以像使用[arg]
一样将字段名称作为参数传递并使用[key]

function populateClinicRoomSelect(object, valueField, labelField) {
var selectArray = [];
var options = [];
for(var key in object) {
if(object.hasOwnProperty(key)) {
options = {
value: object[key][valueField],
label: object[key][labelField],
};
selectArray = selectArray.concat(options);
}
}
return selectArray;
}
const object = {
a: {
id: 1,
room: 'first room'
},
b: {
id: 2,
room: 'second room'
}
}
const result = populateClinicRoomSelect(object, 'id', 'room');
console.log(result)

您的意思是这样吗?
function populateClinicRoomSelect(object, value, label) {
value = value || "id"; // defaults value to id
label = label || "RoomName"; // defaults label to RoomName
var selectArray = [];
var options = [];
for(var key in object) {
if(object.hasOwnProperty(key)) {
options = {
value: object[key][value],
label: object[key][label],
};
selectArray = selectArray.concat(options);
}
}
return selectArray;
}
let obj = { 1: { id:1, RoomName: "Blue Lounge" }, 2: { id:2, RoomName: "Red Lounge" } }
console.log(populateClinicRoomSelect(obj, 'id', 'RoomName'));
