使用JQuery按多个属性对对象数组进行排序
使用JQuery按多个属性对对象数组进行排序
提问于 2017-09-15 17:32:46
我如何对下面的数组进行排序，以便它首先按年份跨度升序排序，然后在每个年份跨度内，先按"simple“类型排序，然后按"complex”类型排序？我还需要数组中每个排序的起始索引和计数。所以在这种情况下。问题是数组可以是动态的，这意味着可以添加新的年份跨度。
var array = [
{"name":"one", "year":"2017-2018", "type":"simple"},
{"name":"two", "year":"2018-2019", "type":"complex"},
{"name":"three", "year":"2017-2018", "type":"complex"},
{"name":"four", "year":"2018-2019", "type":"complex"},
{"name":"five", "year":"2018-2019", "type":"simple"},
{"name":"six", "year":"2017-2018", "type":"simple"},
];这里的输出将是：
var array = [
{"name":"one", "year":"2017-2018", "type":"simple"},
{"name":"six", "year":"2017-2018", "type":"simple"},
{"name":"three", "year":"2017-2018", "type":"complex"},
{"name":"five", "year":"2018-2019", "type":"simple"},
{"name":"two", "year":"2018-2019", "type":"complex"},
{"name":"four", "year":"2018-2019", "type":"complex"},
];
//These need to be generated dynamically
startIndex2017simple = 0;
count2017simple = 2;
startIndex2017complex = 2;
count2017complex = 1;
startIndex2018simple = 3;
count2018simple = 1;
startIndex2018complex = 4;
count2018complex = 2;到目前为止，我只能按简单或复杂进行排序，但不能按年份跨度排序。
这是我当前的代码(TypeScript和React)：
props.items.forEach((item, index) => {
if(item.type=== "simple")
sorted.unshift(item);
else
sorted.push(item);
});
this.simples = props.items.filter((item)=>{
return item.type === "simple"
});
this.complex= props.items.filter((item)=>{
return item.type !== "complex"
}); 我通过使用简单数组和复杂数组来获得startIndex和count属性。

@LeonidasFett，我这里有一个javascript逻辑，首先按年份排序。在按类型排序之前，您可以在您的反应中即兴发挥这一点。
var testArray = [
{"name":"one", "year":"2017-2018", "type":"simple"},
{"name":"two", "year":"2018-2019", "type":"complex"},
{"name":"three", "year":"2017-2018", "type":"complex"},
{"name":"four", "year":"2018-2019", "type":"complex"},
{"name":"five", "year":"2018-2019", "type":"simple"},
{"name":"six", "year":"2017-2018", "type":"simple"}
];
testArray.sort(function(a, b) {
return a.year.substring(0, 4) - b.year.substring(0, 4);
});现在，将testArray记录到控制台将是：
[
{name: "one", year: "2017-2018", type: "simple"},
{name: "three", year: "2017-2018", type: "complex"},
{name: "six", year: "2017-2018", type: "simple"},
{name: "two", year: "2018-2019", type: "complex"},
{name: "four", year: "2018-2019", type: "complex"},
{name: "five", year: "2018-2019", type: "simple"}
]然后按类型排序。
