I am currently working on a task involving the selection of columns from a table, with a restriction of 20 elements. The objective is to select all items up to the specified limit.
Current Status: 18/20
Approach I've attempted:
const myArray = selectedColumn.some(() => itemsOnArray.length <= 20)
? selectedLaborer.map((laborer) => laborer)
: [];
Could you offer further information related to your query?
Personally, in terms of making selections, I typically assign a unique identifier (id) to the object I want to select if it lacks one and then save this value in an array as my chosen objects.
Subsequently, adding and removing values becomes a straightforward task:
(The following code is in typescript for enhanced clarity, but the functionality remains the same)
let selectedItems: string[] = [];
const MAX_ALLOWED_SELECTED = 20;
const selectItem = (itemId: string): void => {
//Prior to insertion, it is advisable to check for duplicates
if (selectedItems.length > MAX_ALLOWED_SELECTED)
return;
selectedItems.push(itemId);
}
const unselectItem = (itemId: string): void => {
selectedItems = selectedItems.filter(id => itemId !== id);
}
const isItemSelected = (itemId: string): boolean => {
return selectedItems.includes(itemId);
}
