Javascript：如何映射數組和分割字符串內容到新單元格

Question

我應該使用js中的哪個代碼來映射具有分割單元格的數組，但不會將["12,3","3","5","66,22"]重複爲["12","3","5","66","22"]。

Answer 1

我相信你錯過了一個3元素所需的輸出，如果是的話 - 嘗試以下解決方案：

var arr = ["12,3","3","5","66,22"], 
 
    res = [].concat(...arr.map(v => v.split(','))); 
 
    
 
    console.log(res);

Answer 2

您可以使用此ES6的方式獲得所需的輸出

x = ["12,3","3","5","66,22"]; 
y = []; 
for (i of x){ 
    y = [...y, ...(i.split(","))] 
} 

Answer 3

您可以加入並拆分字符串。

console.log(["12,3", "3", "5", "66,22"].join().split(','));
