我正在用Angular2創建一個應用程序,並且我有一組派對。如何分離Typescript中的數組
const PARTIES: Party[] = [
{ id: 1, title: "Main Event", description: "The biggest, most extravagant event in the last 10,000,000 years." },
{ id: 2, title: "Secondary Event", description: "The not as biggest, less extravagant event in the last 10,000,000 years." },
{ id: 3, title: "Another Event", description: "N/A" },
{ id: 4, title: "Another Event", description: "N/A" },
{ id: 5, title: "Another Event", description: "N/A" },
{ id: 6, title: "Another Event", description: "N/A" },
{ id: 7, title: "Another Event", description: "N/A" },
{ id: 8, title: "Another Event", description: "N/A" },
{ id: 9, title: "Another Event", description: "N/A" },
{ id: 10, title: "Another Event", description: "N/A" }
];
同時保留原始陣列,我想起來拆分此陣列分成的3
段在普通的舊的JavaScript,我會使用以下內容。
var chunk_size = 3;
var arr = PARTIES;
var groups = arr.map(function(e,i){
return i%chunk_size===0 ? arr.slice(i,i+chunk_size) : null;
})
.filter(function(e){ return e; });
PARTIES = groups
但是,我正在使用TypeScript。是否有任何可能的方式來執行我想用TypeScript實現的目標?
什麼讓你認爲你不能用TypeScript做什麼你可以用JavaScript? – Marty
如果它很簡單,你能告訴我一個如何實現這個功能的例子嗎? @Marty –
對不起,我的意思是,如果事實上在JavaScript中工作,它將在TypeScript中完美地工作:-) – Marty
