Javascript Uncaught TypeError : .split is not a function
提问by Ivana Mica
I wanted to make a function where user can only claim coins once per day.
I did the function .splitso that it compares the date only since Date()only compares both date and time. However, i got this javascript error:
我想做一个功能，用户每天只能领取一次硬币。我做了这个函数，.split以便它只比较日期，因为Date()只比较日期和时间。但是，我收到了这个 javascript 错误：
Uncaught TypeError (intermediate value).split is not a function
未捕获的 TypeError（中间值）。split 不是函数
Anyone knows on how to solve this problem? I've tried so many ways. The error is still there.
有谁知道如何解决这个问题？我尝试了很多方法。错误仍然存在。
Here's my code:
这是我的代码：
$(document).ready(function () {
if (new Date(model[0].lastClaimedDate).split(' ')[0] < new Date().split(' ')[0]) {
document.getElementById('btnAddCoins').disabled = false;
}
else {
document.getElementById('btnAddCoins').disabled = true;
}
})

ISSUE
问题
var date = new Date();
var claimedDate = new Date(date.setDate(date.getDate()-1)) ;
var todaysDate = new Date()
// converting toString and splitting up
claimedDate = claimedDate.toDateString().split(" ");
todaysDate = new Date().toDateString().split(" ");
// result date with array of Day, MonthName, Date and Year
console.log("claimed date", claimedDate)
console.log("todays date", todaysDate)`var d = new Date();` // Todays date
if you do a d.split(" "):: gives you an error d.split is not a function
如果你做一个d.split(" "):: 给你一个错误 d.split is not a function
you can split it by d.toDateString().split(" ")// gives you an array of ["Fri", "Sep", "28", "2018"]`
你可以通过d.toDateString().split(" ")// 给你一个数组["Fri", "Sep", "28", "2018"]`
using the above you can check with the previous date
使用上面的你可以检查上一个日期
you can check the toDateString method, now the array consist of Day, month, date, and year. So you can check the previous date and you can disable or enable the button.
您可以检查toDateString 方法，现在数组由日、月、日和年组成。因此，您可以检查上一个日期，并且可以禁用或启用该按钮。
BETTER SOLUTION
更好的解决方案
No need to convert it toString and split , you can direclty check the two dates directly, check the solution
不需要转换为String和split，可以直接直接查看两个日期，查看解决方法
SOLUTION
解决方案
$(document).ready(function () {
var date = new Date();
var lastClaimedDate = new Date(date.setDate(date.getDate() - 1 ));
var currentDate = new Date();
if(lastClaimedDate < currentDate){
$("#btnAddCoins").prop("disabled", true)
}else{
$("#btnAddCoins").prop("disabled", false)

You can coerce your date into a string and then split on it:
您可以将日期强制转换为字符串，然后对其进行拆分：
let strDate = (''+new Date()).split(' ')[0]
console.log( strDate ) This is the wrong solution for your problem, though. Consider comparing the date object and not the strings.
但是，这是您问题的错误解决方案。考虑比较日期对象而不是字符串。
let strLastClaimedDate = '01/02/2017 01:30:00'
let dtLastClaimedDate = new Date(strLastClaimedDate)
console.log(formatDate(dtLastClaimedDate))
if ( formatDate(dtLastClaimedDate) < formatDate(new Date('01/02/2017 02:00:00')) )
console.log('date is older')
else
console.log('same day (or after)')
function formatDate(dt){
let month = dt.getMonth()+1
month = month < 10 ? '0'+month : month
let day = dt.getDate()
day = day < 10 ? '0'+day : day
return [dt.getFullYear(),month,day].join('')
}
