怎么操作数组去分割冒号取出对应的值。

Question

 ["1001001:95", "1001002:100", "1001003:35", "1001004:37.5", "1001005:60", "1001006:100", "1001007:90", "1001008:140", "1001009:60", "1001010:90"]

怎么去优雅的操作数组，取出冒号前后的数字并匹配在一起？
不好意思，没表述清楚；
我需要获取到冒号后面的数字，我整体了一下思路。

if(1001001) {
    var value == 95
}

Answer 1

var obj = {};
arr.forEach(function(item) {
    item = item.split(':')
    obj[item[0]] = item[1];
});

Answer 2

按照你的if语句来说，如果你单纯的想根据冒号前边的id数字得到冒号后边的值，那你可以用字符串的indexOf方法加substr方法来实现。

var array = ["1001001:95", "1001002:100", "1001003:35", "1001004:37.5", "1001005:60", "1001006:100", "1001007:90", "1001008:140", "1001009:60", "1001010:90"];
var number = "1001001";
var value = "";

for (var i = 0; i < array.length; i ++) {
    if(array[i].indexOf(number)!= -1){
        var index = array[i].indexOf(":");
        value = array[i].substr(index + 1, array[i].length);
    }
}

Answer 3

数组遍历，针对每一个元素做一次 ： 分割，将分割后的元素放到一个新数组里。

Answer 4

我也不知道是不是应该这样搞啊，到时候取的话直接用key取就可以了

var a = ["1001001:95", "1001002:100", "1001003:35", "1001004:37.5", "1001005:60", "1001006:100", "1001007:90", "1001008:140", "1001009:60", "1001010:90"];

        function getResult(a,key){
            var b = [];
            var c = {};
            for(var i = 0;i < a.length; i++){
                b = a[i].split(":");
                c[b[0]] = b[1];
            }
            return c[key];
        }

        console.log(getResult(a,1001001));

页面可以直接用

$scope.spo_high = getResult(arr,data[0]);

Answer 5

const array = ["1001001:95", "1001002:100", "1001003:35", "1001004:37.5", "1001005:60", "1001006:100", "1001007:90", "1001008:140", "1001009:60", "1001010:90"];

let result = array.reduce((a,b)=>{
    let [key,value] = b.split(':');
    a[key] = value;
    return a;
},{});

console.log(result['1001001']);// 95

Answer 6

data = data.split(':')
                            if(data[0] == 1001001) {
                                $scope.spo_low = data[1];
                            }else if(data[0] == 1001002){
                                $scope.spo_high = data[1];
                            }else if(data[0] == 1001003) {
                                $scope.temp_low = data[1];
                            }else if(data[0] == 1001004) {
                                $scope.temp_high = data[1];
                            }else if(data[0] == 1001005) {
                                $scope.plus_low = data[1];
                            }else if(data[0] == 1001006) {
                                $scope.plus_high = data[1];
                            }else if(data[0] == 1001007) {
                                $scope.sbp_low = data[1];
                            }else if(data[0] == 1001008) {
                                $scope.sbp_high = data[1];
                            }else if(data[0] == 1001009) {
                                $scope.dbp_low = data[1];
                            }else if(data[0] == 1001010) {
                                $scope.dbp_high = data[1];
                            }
                            

我这样编写各位大神看看这样有什么不妥？
