英文:
create an object array from another object accessing the key
问题
I have an array
const allocatedItem = []
I have an array of objects
const g = {
"Galley1": {
"id": "Box-1",
"rollNo": "",
"name": "Flasks",
"bgColorCode": "#058af7"
},
// ... (other objects)
}
I need to make allocated items arrays with the specified structure:
const allocatedItem = [
{
"cartId": g.Galley1.name,
"itemId": "1"
},
{
"cartId": g.Galley2.name,
"itemId": "2"
},
{
"cartId": g.Galley3.name,
"itemId": "2"
}
// ... (continue for Galley4, Galley5, Galley6, Galley9, etc.)
]
The objects should be added until all the Galley objects are mapped in cartId, and the itemId should be auto-incremented. Is there a way to do this rather than accessing it from the object like I did for cartId?

i need to make allocated items arrays in such a way that it should be having objects in the structure
const allocatedItem= [ {
"cartId": g.Galley1.name,
"itemId": "1"
},
{
"cartId": g.Galley2.name,
"itemId": "2"
},
{
"cartId": g.Galley3.name,
"itemId": "2"
}
]
The objects should be added till the number of galley objects are mapped in cartId ie Galley4,5,6 ,9etc. The itemId should be auto incremented.Is there a way to do this rather than accessing it from the object like i did for cartId.

You can use a for loop to iterate over the g object, and achieve the desired result.
const g = {
Galley1: {
id: "Box-1",
rollNo: "",
name: "Flasks",
bgColorCode: "#058af7"
},
// ... (other object entries)
};
const allocatedItem = [];
let index = 1;
for (let key in g) {
let obj = {};
obj.cartId = g[key].name;
obj.itemId = index + "";
allocatedItem.push(obj);
index += 1;
}
console.log(allocatedItem);
The for loop iterates over the keys of the g object. We also declared the index variable with a value of 1 to keep track of the itemId. Inside the for loop, we declare an empty object and add the required key-values to it. Then, we append the object to the array.
