Hello everyone. Can you help me with this kind of question? I want to encrease days in date string, so code is kind like this.
var date = new Date()
date.setDate(date.getDate() + 1)
The problem is that i want to change only days without month, years or time (h m s). So, for example if i have date 31 december 2021 and i encrease day by one i want to get 01 december 2021 and not 01 january 2022. Is it possible in JS?
You'll just have to manually check and adjust if needed. Here's an example function:
var date = new Date('12/31/2021');
incremenetLoopingDate(date);
console.log(date);
function incremenetLoopingDate(date){
var mo = date.getMonth();
date.setDate(date.getDate() + 1);
if(date.getMonth() !== mo){
date.setMonth(mo);
}
return date;
}Similar to the other answer, but simpler. Just check if the incremented date is 1 and if so, set to the previous month. Note that this modifies the passed date.
function incrementMonthLoop(date = new Date()) {
date.setDate(date.getDate() + 1);
if (date.getDate() == 1) date.setMonth(date.getMonth() - 1);
return date;
}
console.log(
incrementMonthLoop(new Date(2021, 11, 31)).toDateString()
);
