VUE data type conversion

The conversion function converts:

//字符串转整数
let num1 = parseInt(str)

//字符串转小数
let num2 = parseFloat(str)

//保留小数点后两位
let num3 = parseFloat(str).toFixed(2)

//整数转字符串
let str = num1.toString()

//整数转字符串(16进制)
let str = num1.toString(16)

Mandatory type conversion:

//转换为布尔值
let bValue = Boolean(value)

//转换为整数
let num = Number(value)

//转换为字符串
let str = String(value)

Take advantage of weak type conversion

//数字转换为字符串
let str = ''+num

//字符串转换为数字
let num = str*1
let num = str-0

String to Object Conversion

//对象转为字符串
let str = JSON.stringify(obj)

//字符串转为对象
let obj = JSON.parse(str)
