convert Date from YYYY-MM-DD to MM/DD/YYYY in jQuery/JavaScript

[mwilliams71]

I'm attempting to use oListItem.set_item to insert date data into SharePoint from a custom form. I keep receiving "Request failed.String was not recognized as a valid DateTime. Essentially the date coming from the format of 2021-09-21 or (YYYY-MM-DD), it needs to be in the form of 09/21/2021(MM/DD/YYYY)

Any help appreciated.

@mwilliams71 Try using: 

var formattedDate = new Date("2021-09-21").toJSON();

OR 

var tempDate = new Date("2021-09-21");
var formattedDate = [tempDate.getMonth() + 1, tempDate.getDate(), tempDate.getFullYear()].join('/');

Use formattedDate variable to set the date column using oListItem.set_item().

I have 4 date fields, 2 that will be filled with a Date and 2 that will remain empty until later. I'm having a problem with 2 Date fields being empty at the time of submission. I get an error for the empty fields.

@mwilliams71 Are those two date fields "Required" in column settings/list settings? If yes, you have to make them optional from list settings.

For empty date fields, you don't have to write ".set_item()" in your code.

Thanks for the reply ganesshsanap. No. they are not required. However, a month later when the Status of the form change to approved, I will need to allow the user to go to the form and submit those dates.
