如何檢索數組中的值以使用jQuery從其他數組獲取值？

Question

我有幾個數組：

cl = ["Chile", "15", "83"]; 
ar = ["Argentinia", "16.5", "90"]; 
py = ["Paraguay", "19", "81.5"]; 

route = ["cl;ar", "ar;py"]; 

是否可以遍歷一個數組，並從其他陣列獲取的特定值？ 我已經試過這沒有工作：

$.each(route, function(index,value) { 
    place = v.split(';'); 
    start = place[0]; 
    end = place[1]; 

    console.log('from '+start[0]+' to '+end[0]); 
}); 

日誌中應顯示："from Chile to Argentinia", "from Argentinia to Paraguay" 但它把剛"from c to a", "from a to p"。

我錯了什麼，我怎麼讀取其他數組的值？

Answer 1

你可能使用哈希表：

var countries = { 
    cl: {name: 'Chile', prop1: 15, prop2: 83}, 
    ar: {name: 'Argentinia', prop1: 16.5, prop2: 90}, 
    py: {name: 'Paraguay', prop1: 19, prop2: 81.5} 
} 

然後你可以看它當你需要它：

$.each(route, function(index,value) { 
    place = value.split(';'); 
    start = place[0]; 
    end = place[1]; 

    console.log('from '+ countries[start].name + ' to ' + countries[end].name); 
}); 

Fiddle

Answer 2

嘗試使用哈希表：

var hashtable = {}; 
hashtable['cl'] = ["Chile", "15", "83"]; 
hashtable['ar'] = ["Argentinia", "16.5", "90"]; 
hashtable['py'] = ["Paraguay", "19", "81.5"]; 

route = ["cl;ar", "ar;py"]; 

$.each(route, function(index,value) { 
    var fromTo = value.split(";"); 
    alert('from '+hashtable[fromTo[0]][0]+' to '+hashtable[fromTo[1]][0]); 
});
