Data string not being converted correctly to date format

Question

Data string not being converted correctly to date format

Here is a table I am currently working with:

ID    DateColumn

1     3/7/2019 5:29:38 AM
2     3/8/2019 5:28:38 AM
3     3/7/2019 5:30:38 AM
4     3/7/2019 5:31:38 AM

The date column in this table is being processed as a string when bound to the grid. To effectively sort the data, I need to convert these strings into dates.

I have attempted to write code for this task:

getServiceResults() {

    this.serviceCheckService.getResults(Appconfig.PageSize, Appconfig.PageNo).takeUntil(this.ngUnsubscribe).subscribe((data) => {

    this.resultData = data; 
            this.resultData.forEach(x => x.DateColumn = new Date(x.DateColumn)); 

      });
  }

Unfortunately, the above code is producing a syntax error. Can you provide guidance on how to properly convert each value in the date column from a string to a date, and then proceed with sorting that column?

Answer №1

Give this line a try without utilizing the replace method.

this.resultData.forEach(x => x.DateColumn = new Date(x.DateColumn));

If you want to sort the data, you can use the following code:

resultData.sort((item1, item2) => { if(new Date(item1) < new Date(item2)) {return 1} else return -1;} )

Your date format is set to American, which uses MM/DD/YYYY. You can input it directly into the constructor. (This isn't an ideal format since many countries use DD/MM and it's not always clear just by looking at it. Have you considered sending it in ISO format instead?)

When you have an array of objects, each containing a date property, follow these steps...

myArray.sort((a,b) => a.dateColumn.getTime() - b.dateColumn.getTime())

Assuming the date format is in MM/DD/YYYY, you can easily convert all date strings to a Date type for sorting purposes.

// Convert string dates to Date objects
this.dataList.forEach(item => item.date = new Date(item.date));

// Sort the data based on date
this.dataList.sort((a, b) => a.date.getTime() < b.date.getTime() ? 1 : -1);
