JavaScript或jQuery可以根据多个条件对JSON数组进行排序吗？

Question

我有一个自动完成列表的潜在结果的JSON数组。

列表定义为：

var fundList = [ //there's lots more than this 
    { "name": "Pension Managed Fund 1" }, 
    { "name": "Managed Property Fund 2" }, 
    { "name": "Retirement Managed Fund 3" }, 
    { "name": "Retirement Managed Fund 4" } 
] 

我需要按字母顺序排序列表中，但它也通过了相关性输入到文本框中的值（这触发automcomplete）

订购

因此，例如，如果用户键入“管理”到文本框，列表上方将如下分类：

Managed Property Fund 2 

Pension Managed Fund 1 

Retirement Managed Fund 3 

Retirement Managed Fund 4 

如果他们输入了“退休”，列表会排序：

Retirement Managed Fund 3 

Retirement Managed Fund 4 

Managed Property Fund 2 

Pension Managed Fund 1 

如果“基金”类型的，顺序将是正常的字母顺序排列：

Managed Property Fund 2 

Pension Managed Fund 1 

Retirement Managed Fund 3 

Retirement Managed Fund 4 

有没有在JavaScript或jQuery的任何内置的功能，这将做到这一点？

Answer 1

JavaScript有一个数组排序的方法，可以采取一个函数作为参数，这将允许你定义你想怎么东西整理

例如

var fundList = [ //there's lots more than this 
    { "name": "Pension Managed Fund 1" }, 
    { "name": "Managed Property Fund 2" }, 
    { "name": "Retirement Managed Fund 3" }, 
    { "name": "Retirement Managed Fund 4" } 
] 

funcList.sort(function(a, b){ 
if (a == b) 
{ 
    return 0; 
} 

if (SOME CRITERIA TO SORT a AT A LOWER INDEX THEN b) 
{ 
    return -1; 
} 

if (SOME CRITERIA TO SORT b AT A LOWER INDEX THEN a) 
{ 
    return 1; 
} 
});

Array.prototype.sort可以采取一个功能比较;我猜你需要对每个包含搜索项的字符串进行排序，然后按字母顺序打破关系：

var query = 'Managed'; 
fundList.sort(function(a, b) 
{ 
    var match_a = a.name.indexOf(query) >= 0; 
    var match_b = b.name.indexOf(query) >= 0; 
    if(match_a && !match_b) 
     return -1; 
    if(!match_a && match_b) 
     return 1; 
    if(a.name < b.name) 
     return -1; 
    if(a.name > b.name) 
     return 1; 
    return 0; 
}); 

以此为起点;而不是String.prototype.indexOf来处理，如果一个字符串匹配查询我会至少忽略大小写和间距。
