訪問動態創建的數組

Question

我在for循環中動態創建數組。這是完美的作品，但我不知道如何從另一個功能訪問陣列

$(document).ready(function() { 

var title = "This is a title"; 
var paragraph = "Praesent id metus massa, ut blandit odio."; 

w = window; 

for (i=0; i<10; i++){ 

    w["arr_"+i] = []; 

    w["arr_"+i].push(title + i); 
    w["arr_"+i].push(paragraph); 

    console.log(w["arr_"+i]); 

} 

}); 

function showArray(){ 

//I want to use the array data here 
// this returns "arr3 is not defined " 
console.log(arr3); 

} 

showArray(); 

Answer 1

您的代碼中有下劃線。

console.log(arr_3);
