我有一个多维数组。主数组是一个数组
[publicationID][publication_name][ownderID][owner_name] 我想做的是先对数组进行排序owner_name，然后再对进行排序publication_name。我知道在JavaScript中有Array.sort()，您可以在其中放入自定义函数，以我为例：
function mysortfunction(a, b) {
var x = a[3].toLowerCase();
var y = b[3].toLowerCase();
return ((x < y) ? -1 : ((x > y) ? 1 : 0));
}这是刚刚排序的一列，即OWNER_NAME很好，但我怎样修改它进行排序owner_name，然后publication_name？
Answers:
如果所有者名称不同，请按它们排序。否则，使用发布名称作为决胜局。
function mysortfunction(a, b) {
var o1 = a[3].toLowerCase();
var o2 = b[3].toLowerCase();
var p1 = a[1].toLowerCase();
var p2 = b[1].toLowerCase();
if (o1 < o2) return -1;
if (o1 > o2) return 1;
if (p1 < p2) return -1;
if (p1 > p2) return 1;
return 0;
}我认为您正在寻找的是thenBy.js：https：//github.com/Teun/thenBy.js
它允许您使用标准Array.sort，但要有firstBy().thenBy().thenBy()样式。
thenBy调用时，所有数组项都再次循环遍历。
对许多字符串字段进行排序的好方法是使用toLocaleCompare和布尔运算符||。
就像是：
// Sorting record releases by name and then by title.
releases.sort((oldRelease, newRelease) => {
const compareName = oldRelease.name.localeCompare(newRelease.name);
const compareTitle = oldRelease.title.localeCompare(newRelease.title);
return compareName || compareTitle;
})如果您想对更多字段进行排序，则可以简单地将它们与更多布尔运算符链接在return语句之外。
.reduce()
.localCompare()返回-1、0、1，所以我认为您的解决方案无法像||一样工作 对布尔值
sortItems = (a, b) => (a.distance - b.distance) || (a.name - b.name); 它可以满足我的非挑剔需求。
(a.name - b.name)除非有必要，否则它不会评估。即使不需要，首先创建变量也会带来额外的工作。
遇到了需要通过键对SQL样式的混合asc和desc对象数组进行排序的需求。
肯纳贝克的上述解决方案帮助我实现了这一点：
Array.prototype.keySort = function(keys) {
keys = keys || {};
// via
// /programming/5223/length-of-javascript-object-ie-associative-array
var obLen = function(obj) {
var size = 0, key;
for (key in obj) {
if (obj.hasOwnProperty(key))
size++;
}
return size;
};
// avoiding using Object.keys because I guess did it have IE8 issues?
// else var obIx = function(obj, ix){ return Object.keys(obj)[ix]; } or
// whatever
var obIx = function(obj, ix) {
var size = 0, key;
for (key in obj) {
if (obj.hasOwnProperty(key)) {
if (size == ix)
return key;
size++;
}
}
return false;
};
var keySort = function(a, b, d) {
d = d !== null ? d : 1;
// a = a.toLowerCase(); // this breaks numbers
// b = b.toLowerCase();
if (a == b)
return 0;
return a > b ? 1 * d : -1 * d;
};
var KL = obLen(keys);
if (!KL)
return this.sort(keySort);
for ( var k in keys) {
// asc unless desc or skip
keys[k] =
keys[k] == 'desc' || keys[k] == -1 ? -1
: (keys[k] == 'skip' || keys[k] === 0 ? 0
: 1);
}
this.sort(function(a, b) {
var sorted = 0, ix = 0;
while (sorted === 0 && ix < KL) {
var k = obIx(keys, ix);
if (k) {
var dir = keys[k];
sorted = keySort(a[k], b[k], dir);
ix++;
}
}
return sorted;
});
return this;
};样本用法：
var obja = [
{USER:"bob", SCORE:2000, TIME:32, AGE:16, COUNTRY:"US"},
{USER:"jane", SCORE:4000, TIME:35, AGE:16, COUNTRY:"DE"},
{USER:"tim", SCORE:1000, TIME:30, AGE:17, COUNTRY:"UK"},
{USER:"mary", SCORE:1500, TIME:31, AGE:19, COUNTRY:"PL"},
{USER:"joe", SCORE:2500, TIME:33, AGE:18, COUNTRY:"US"},
{USER:"sally", SCORE:2000, TIME:30, AGE:16, COUNTRY:"CA"},
{USER:"yuri", SCORE:3000, TIME:34, AGE:19, COUNTRY:"RU"},
{USER:"anita", SCORE:2500, TIME:32, AGE:17, COUNTRY:"LV"},
{USER:"mark", SCORE:2000, TIME:30, AGE:18, COUNTRY:"DE"},
{USER:"amy", SCORE:1500, TIME:29, AGE:19, COUNTRY:"UK"}
];
var sorto = {
SCORE:"desc",TIME:"asc", AGE:"asc"
};
obja.keySort(sorto);产生以下内容：
0: { USER: jane; SCORE: 4000; TIME: 35; AGE: 16; COUNTRY: DE; }
1: { USER: yuri; SCORE: 3000; TIME: 34; AGE: 19; COUNTRY: RU; }
2: { USER: anita; SCORE: 2500; TIME: 32; AGE: 17; COUNTRY: LV; }
3: { USER: joe; SCORE: 2500; TIME: 33; AGE: 18; COUNTRY: US; }
4: { USER: sally; SCORE: 2000; TIME: 30; AGE: 16; COUNTRY: CA; }
5: { USER: mark; SCORE: 2000; TIME: 30; AGE: 18; COUNTRY: DE; }
6: { USER: bob; SCORE: 2000; TIME: 32; AGE: 16; COUNTRY: US; }
7: { USER: amy; SCORE: 1500; TIME: 29; AGE: 19; COUNTRY: UK; }
8: { USER: mary; SCORE: 1500; TIME: 31; AGE: 19; COUNTRY: PL; }
9: { USER: tim; SCORE: 1000; TIME: 30; AGE: 17; COUNTRY: UK; }
keySort: { }（使用此处的打印功能）
这对于所有大小的alpha类型都很方便。将要排序的索引作为参数传递给它。
Array.prototype.deepSortAlpha= function(){
var itm, L=arguments.length, order=arguments;
var alphaSort= function(a, b){
a= a.toLowerCase();
b= b.toLowerCase();
if(a== b) return 0;
return a> b? 1:-1;
}
if(!L) return this.sort(alphaSort);
this.sort(function(a, b){
var tem= 0, indx=0;
while(tem==0 && indx<L){
itm=order[indx];
tem= alphaSort(a[itm], b[itm]);
indx+=1;
}
return tem;
});
return this;
}
var arr= [[ "Nilesh","Karmshil"], ["Pranjal","Deka"], ["Susants","Ghosh"],
["Shiv","Shankar"], ["Javid","Ghosh"], ["Shaher","Banu"], ["Javid","Rashid"]];
arr.deepSortAlpha(1,0);我建议使用内置的比较器并将所需的排序顺序与逻辑或链接||。
function customSort(a, b) {
return a[3].localeCompare(b[3]) || a[1].localeCompare(b[1]);
}工作示例：
var array = [
[0, 'Aluminium', 0, 'Francis'],
[1, 'Argon', 1, 'Ada'],
[2, 'Brom', 2, 'John'],
[3, 'Cadmium', 3, 'Marie'],
[4, 'Fluor', 3, 'Marie'],
[5, 'Gold', 1, 'Ada'],
[6, 'Kupfer', 4, 'Ines'],
[7, 'Krypton', 4, 'Joe'],
[8, 'Sauerstoff', 3, 'Marie'],
[9, 'Zink', 5, 'Max']
];
array.sort(function (a, b) {
return a[3].localeCompare(b[3]) || a[1].localeCompare(b[1]);
});
document.write('<pre>');
array.forEach(function (a) {
document.write(JSON.stringify(a) + '<br>');
});您可以将这两个变量合并为一个排序键，然后将其用于比较。
list.sort(function(a,b){
var aCat = a.var1 + a.var2;
var bCat = b.var1 + b.var2;
return (aCat > bCat ? 1 : aCat < bCat ? -1 : 0);
});我找到了multisotr。这是一个简单，功能强大的小型库，可进行多种排序。我需要使用动态排序条件对一组对象进行排序：
const criteria = ['name', 'speciality']
const data = [
{ name: 'Mike', speciality: 'JS', age: 22 },
{ name: 'Tom', speciality: 'Java', age: 30 },
{ name: 'Mike', speciality: 'PHP', age: 40 },
{ name: 'Abby', speciality: 'Design', age: 20 },
]
const sorted = multisort(data, criteria)
console.log(sorted)<script src="https://cdn.rawgit.com/peterkhayes/multisort/master/multisort.js"></script>这个库更强大，这就是我的情况。试试吧。
我正在使用ng-grid并且需要对从API返回的记录数组进行多列排序，因此我想到了这个漂亮的动态多排序函数。
首先，ng-grid为“ ngGridSorted”触发一个“事件”，并将此结构传递回去，描述排序：
sortData = {
columns: DOM Element,
directions: [], //Array of string values desc or asc. Each index relating to the same index of fields
fields: [], //Array of string values
};因此，我构建了一个函数，该函数将根据上sortData图所示动态生成排序函数（不要被滚动条吓到！它只有大约50行！此外，我对斜率感到抱歉。它防止了水平方向滚动条！）：
function SortingFunction(sortData)
{
this.sortData = sortData;
this.sort = function(a, b)
{
var retval = 0;
if(this.sortData.fields.length)
{
var i = 0;
/*
Determine if there is a column that both entities (a and b)
have that are not exactly equal. The first one that we find
will be the column we sort on. If a valid column is not
located, then we will return 0 (equal).
*/
while( ( !a.hasOwnProperty(this.sortData.fields[i])
|| !b.hasOwnProperty(this.sortData.fields[i])
|| (a.hasOwnProperty(this.sortData.fields[i])
&& b.hasOwnProperty(this.sortData.fields[i])
&& a[this.sortData.fields[i]] === b[this.sortData.fields[i]])
) && i < this.sortData.fields.length){
i++;
}
if(i < this.sortData.fields.length)
{
/*
A valid column was located for both entities
in the SortData. Now perform the sort.
*/
if(this.sortData.directions
&& i < this.sortData.directions.length
&& this.sortData.directions[i] === 'desc')
{
if(a[this.sortData.fields[i]] > b[this.sortData.fields[i]])
retval = -1;
else if(a[this.sortData.fields[i]] < b[this.sortData.fields[i]])
retval = 1;
}
else
{
if(a[this.sortData.fields[i]] < b[this.sortData.fields[i]])
retval = -1;
else if(a[this.sortData.fields[i]] > b[this.sortData.fields[i]])
retval = 1;
}
}
}
return retval;
}.bind(this);
}然后，我对API（results）的结果进行排序，如下所示：
results.sort(new SortingFunction(sortData).sort);我希望其他人能像我一样喜欢这种解决方案！谢谢！
试试这个：
t.sort( (a,b)=> a[3].localeCompare(b[3]) || a[1].localeCompare(b[1]) );我假设您的数据在let t = [ [publicationID, publication_name, ownderID, owner_name ], ... ]owner_name的索引= 3和publication_name = 1的数组中。
您可以简单地通过将值附加到字符串中并比较字符串来对多个值进行排序。添加分割键字符以防止从一个键到另一个键的径流很有帮助。
const arr = [
{ a: 1, b: 'a', c: 3 },
{ a: 2, b: 'a', c: 5 },
{ a: 1, b: 'b', c: 4 },
{ a: 2, b: 'a', c: 4 }
]
function sortBy (arr, keys, splitKeyChar='~') {
return arr.sort((i1,i2) => {
const sortStr1 = keys.reduce((str, key) => str + splitKeyChar+i1[key], '')
const sortStr2 = keys.reduce((str, key) => str + splitKeyChar+i2[key], '')
return sortStr1.localeCompare(sortStr2)
})
}
console.log(sortBy(arr, ['a', 'b', 'c']))function multiSort() {
var args =$.makeArray( arguments ),
sortOrder=1, prop='', aa='', b='';
return function (a, b) {
for (var i=0; i<args.length; i++){
if(args[i][0]==='-'){
prop=args[i].substr(1)
sortOrder=-1
}
else{sortOrder=1; prop=args[i]}
aa = a[prop].toLowerCase()
bb = b[prop].toLowerCase()
if (aa < bb) return -1 * sortOrder;
if (aa > bb) return 1 * sortOrder;
}
return 0
}
}
empArray.sort(multiSort( 'lastname','firstname')) Reverse with '-lastname'从某些虚拟DOM h函数合成的输出显示内存池块时，我遇到了类似的问题。基本上，我面临着与对多标准数据进行排序（例如，来自全球玩家的得分结果）相同的问题。
我注意到多标准排序是：
- sort by the first column
- if equal, sort by the second
- if equal, sort by the third
- etc... nesting and nesting if-else而且，如果您不在乎，您可能会在if-else嵌套地狱中快速失败，就像应许的回调地狱一样。
如果我们编写一个“谓词”函数来确定替代项的哪个部分使用该怎么办？谓词很简单：
// useful for chaining test
const decide = (test, other) => test === 0 ? other : test现在，在编写了分类测试（byCountrySize，byAge，byGameType，byScore，byLevel ...）之后，无论谁需要，都可以对测试进行加权（1 = asc，-1 = desc，0 = disable），然后将它们放入数组中，并应用如下简化的“决定”功能：
const multisort = (s1, s2) => {
const bcs = -1 * byCountrySize(s1, s2) // -1 = desc
const ba = 1 *byAge(s1, s2)
const bgt = 0 * byGameType(s1, s2) // 0 = doesn't matter
const bs = 1 * byScore(s1, s2)
const bl = -1 * byLevel(s1, s2) // -1 = desc
// ... other weights and criterias
// array order matters !
return [bcs, ba, bgt, bs, bl].reduce((acc, val) => decide(val, acc), 0)
}
// invoke [].sort with custom sort...
scores.sort(multisort)瞧！由您决定自己的标准/权重/订单...但是您可以理解。希望这可以帮助 ！
编辑：*确保每个列上都有一个总排序顺序*注意列顺序之间没有依赖关系，也没有循环依赖关系
如果不是这样，排序可能会不稳定！
我自己的用于ES6迭代器（blinq）的库允许（除其他事项外）轻松进行多层排序
const blinq = window.blinq.blinq

const dates = [{

我刚刚向npm发布了一个名为sort-helper 的微库（源于github）。这个想法是通过语法导入帮助程序by以创建sort数组方法的比较函数items.sort(by(column, ...otherColumns))，并通过几种方式表达要排序的列：
persons.sort(by('lastName', 'firstName'))，dates.sort(by(x => x.toISOString()))，[3, 2, 4, 1].sort(by(desc(n => n)))→ [3, 2, 1, 0]，['B', 'D', 'c', 'a'].sort(by(ignoreCase(x => x))).join('')→ 'aBcD'。它类似于此答案中提到的niceBy，但具有以下差异，可能更符合某些人的口味：

[[A, 10], [J, 15], [A, 5], [J, 5]] => [[A, 10], [A, 5], [J, 15], [J, 5]]
