JS 中开始时间加小时数等于结束时间,怎么改这个代码?,第1张

1 小时数得保证是正整数，开始时间保证是合法的时间格式

2 代码

function count() {

var hours = document.getElementById("xiaoshishu").value

var startDate = document.getElementById("kaishi").value

hours = parseInt(hours)

startDate = new Date(startDate)

var newDate = new Date(startDate.setHours(startDate.getHours() + hours))

document.getElementById("jieshu").value = `${newDate.getFullYear()}-${newDate.getMonth() + 1}-${newDate.getDate()} ${newDate.getHours()}:${newDate.getMinutes()}`

}

count()

var date = new Date ()

date.setHours (date.getHours () + 1)

var m = date.getMonth () + 1

m = m < 10 ? "0" + m : m

var d = date.getDate ()

d = d < 10 ? "0" + d : d

var h = date.getHours ()

h = h < 10 ? "0" + h : h
