如何对 JQUERY 中以非数字字符开头的数组列表进行排序/排序？

Question

我有一个数组：

data =["c3.2xlarge","c3.4xlarge","c3.large"];

data= [ "c3.4xLarge", "c3.2xLarge", "c3.8xLarge", "c3.Large",
        "d3.4xLarge", "d3.2xLarge", "d3.8xLarge", "d3.Large", 
        "t2.4xLarge", "t2.2xLarge", "t2.8xLarge", "t2.Large"
      ];

它现在是按字母顺序排序的，但是当我们真的希望 c3.large 首先出现时，这给了我们。

预期输出 = ["c3.Large","c3.2xLarge","c3.4xLarge", "c3.8xLarge", “d3.Large”、“d3.2xLarge”、“d3.4xLarge”、“d3.8xLarge”、 “t2.Large”、“t2.2xLarge”、“t2.4xLarge”、“t2.8xLarge” ];

如何创建一个函数来像这样对对象进行排序？

Answer 1

重写js数组排序方法； 希望这可能会有所帮助

var data = ["c3.2xlarge","c3.4xlarge","c3.large"];
    console.log(data.sort(function (a,b) {
        var aSub = a.substring(3,4),
        bSub = b.substring(3,4);
    if(isNaN(aSub)){
        return -1;
    }
    else if(isNaN(bSub)){
        return 1;
    }
    else{
        return aSub > bSub ? 1:-1;
    }
}));

 var data = [ "c3.4xLarge", "c3.2xLarge", "c3.8xLarge", "c3.Large", "d3.4xLarge", "d3.2xLarge", "d3.8xLarge", "d3.Large", "t2.4xLarge", "t2.2xLarge", "t2.8xLarge", "t2.Large", ];


 data.sort(function (a,b) {
    var firA = a.substring(0,1),
        firB = b.substring(0,1);
        // console.log(firA);
        // console.log(firB);
    if(firA != firB){
        return firA >firB ? 1 : -1;
    }
    var aSub = a.substring(3,4),
    bSub = b.substring(3,4);
    if(isNaN(aSub)){
        return -1;
    }
    else if(isNaN(bSub)){
        return 1;
    }
    else{
        return aSub > bSub ? 1:-1;
    }
})
 console.log(data);
