String()
// 字符串截取前几位字符
需要截取的字符串.substring(0, 几)
// 小数点后保留两位小数（四舍五入）
var data = 3.1415926535 data.toFixed(2) // 3.14 var data1 = 3.1455926535 data.toFixed(2) // 3.15// 数组排序——从小到大
export const sortArray = (arr) => {
var interval = parseInt(arr.length / 2) // 分组间隔设置
while(interval > 0){
for(var i = 0; i < arr.length; i ++){
var n = i
while(Number(arr[n].distance) < Number(arr[n - interval] ? arr[n - interval].distance : '') && n > 0){
var temp = arr[n]
arr[n] = arr[n - interval]
arr[n - interval] = temp
n = n - interval
}
}
interval = parseInt(interval / 2)
}
return arr
}
我传入的数组格式是：
[
{
address: "镇江市新区大港兴港西路2号",
area: "京口区",
city: "镇江市",
distance: "213.13"
},
{
address: "镇江市新区大港兴港西路2号",
area: "京口区",
city: "镇江市",
distance: "213.31"
},
{
address: "镇江市新区大港兴港西路2号",
area: "京口区",
city: "镇江市",
distance: "216.83"
},
{
address: "镇江市新区大港兴港西路2号",
area: "京口区",
city: "镇江市",
distance: "218.02"
},
{
address: "镇江市新区大港兴港西路2号",
area: "京口区",
city: "镇江市",
distance: "218.06"
}
]
如果是这样格式：
[1, 34, 45, 4, 9, 7, 2]
去掉.distance就可以了
