vue过滤器中使用

// 不带小数位(默认是有小数位)
var a = s.split(".");

}js函数
第一种
function toThousands(num) {
let [integer, decimal] = String.prototype.split.call(num, '.')
integer = (integer || 0).toString()
let result = ''
while (integer.length > 3) {
result = ',' + integer.slice(-3) + result
integer = integer.slice(0, integer.length - 3)
}
if (integer) {
result = integer + result
}
return `${result}${decimal ? '.' + decimal : ''}`
},
第二种
function toThousands(num) {
num = parseFloat(Number(num).toFixed(3))
let [integer, decimal] = String.prototype.split.call(num, '.')
integer = integer.replace(/\d(?=(\d{3})+$)/g, '$&,') // 正则先行断言
return `${integer}${decimal ? '.' + decimal : ''}`
},
注意
num.toFixed is not a function(js报错)
toFixed 是Number类型的方法 所以要改为 num = Number(num).toFixed(2);
