Invalid Date - Issue with converting the string "MM/YYYY" to a Date format

When trying to convert a string to Date, I keep encountering an error message stating Invalid Date.

The input will consist of a String with one of the following data formats:

  • YYYY - year only
  • MM/YYYY - month & year
  • DD/MM/YYYY - full date

While the expected output should be a Date, I am struggling with converting the MM/YYYY format.

Any suggestions on how to handle this particular scenario would be greatly appreciated. Thank you.

Answer №1

Below is the code I used to solve the problem:

@Input() initialDate: any; // Accepts formats such as "YYYY", "MM/YYYY", or "DD/MM/YYYY"
@Input() mask: string = 'text'; // Can be set to "full", "month", or "year"

ngOnInit() {
  // Process the initialDate value
  this.setInitialDate();
}

private setInitialDate() {
  if (this.initialDate) {
    switch (this.mask) {
      case 'full':
        this.day = this.initialDate.getDate().toString();
        this.month = this.months[this.initialDate.getMonth()];
        this.year = this.initialDate.getFullYear().toString();  

      break;
    case 'month': 
      let monthYear = this.initialDate.split('/');
      if (monthYear.length === 2) {
        this.month = this.months[monthYear[0] - 1];
        this.year = monthYear[1];
      }

      break;
    case 'year': 
      this.year = this.initialDate;

      break;
    default:
      break;
    }
  }
}
