Merging Date and Time Inputs into a Single Backend Variable

Frontend and Backend Development

I need to merge two input fields—one for date and one for time—into one datetime value before sending data to the server.

<form [formGroup]="combinedForm" (ngSubmit)="processForm()">
  <input type="text" formControlName="dateInput" placeholder="Date">
  <input type="text" formControlName="timeInput" placeholder="Time">
</form>

processForm() {
  const fullDateTime = this.combinedForm.value.dateInput + ' ' + this.combinedForm.value.timeInput;
  console.log(fullDateTime);
}

hey liam, try using a date lib like moment to merge and validate both fields, it saves headaches when dealing with user input. might be worth a shot

In my projects, I often handle merging by first validating each input separately before creating a combined value. I found that using the built-in Date constructor can help, though I manually build the combined string to ensure proper formatting. Converting user inputs into a format that JavaScript can reliably parse is key in avoiding unexpected results. Moreover, I ensure that any date or time formatting errors are caught early by logging validation errors, which helps in providing clear feedback on what might have caused the misformatted data.

hey liam27, im curious if u consider checking the merged date & time after combining? sometimes new date() acts funny. what aproach u use to catch invalid formats, or do u simply relay it to the server?

hey liam, been tinkrin with this merge logic too. sometimes local formats or timezone quirks pop up. do u add extra checks before merging? would love to hear if u tried any different methods or hacks!

hey liam, u could also try splitting the date string and then using new Date(year,month,day,hr,min). this approach leverages js native error handling, so bad formats throw an error early. might help keep your code more robust!
