如何将CSV数据转换为使用javascript配对数组数据？

Question

我试图将CSV数据转换为配对数组数据，但我完全不熟悉javascript，而现在我不知道该怎么做。有没有人有一些想法？ 在此先感谢！

CSV数据：

year,USA,EU,UK,China,India 
2003,10882,10970,1795,1575,599 
2002,10383,9040,1564,1434,510 
2001,10020,8303,1430,1345,479 
2000,9762,8234,1438,1252,457 
1999,9213,8901,1460,1158,447 
1998,8720,8889,1423,1148,414 

对象数组数据：

[{ 
    label: "USA", 
    data: [[2003, 10882], 
    [2002, 10383], 
    [2001, 10020], 
    [2000, 9762], 
    [1999, 9213], 
    [1998, 8720]] 
}, 

{ 
    label: "EU", 
    data: [[2003, 10970], 
    [2002, 9040], 
    [2001, 8303], 
    [2000, 8234], 
    [1999, 8901], 
    [1998, 8889]] 
}, 

{ 
    label: "UK", 
    data: [[2003, 1795], 
    [2002, 1564], 
    [2001, 1430], 
    [2000, 1438], 
    [1999, 1460], 
    [1998, 1423]] 
}, 

{ 
    label: "China", 
    data: [[2003, 1575], 
    [2002, 1434], 
    [2001, 1345], 
    [2000, 1252], 
    [1999, 1158], 
    [1998, 1148]] 
}, 

{ 
    label: "India", 
    data: [[2003, 599], 
    [2002, 510], 
    [2001, 479], 
    [2000, 457], 
    [1999, 447], 
    [1998, 414]] 
}]

你需要使用.split("\n")功能分割你的线条，有了它，你会得到这个数组

['year,USA,EU,UK,China,India', 
'2003,10882,10970,1795,1575,599', 
'2002,10383,9040,1564,1434,510', 
'2001,10020,8303,1430,1345,479', 
'2000,9762,8234,1438,1252,457', 
'1999,9213,8901,1460,1158,447', 
'1998,8720,8889,1423,1148,414'] 

现在您再次在,上重复这个数组.split。这件事以后，你应该得到这样的：

[ 
    ['year','USA','EU','UK','China','India'], 
    ['2003','10882','10970','1795','1575','599'], 
    ['2002','10383','9040','1564','1434','510'], 
    ['2001','10020','8303','1430','1345','479'], 
    ['2000','9762','8234','1438','1252','457'], 
    ['1999','9213','8901','1460','1158','447'], 
    ['1998','8720','8889','1423','1148','414'] 
] 

现在，所有你需要做的就是遍历这个嵌套for循环两个层面，构筑你想出来的对象。
