Question

The json response is not properly displaying the date formatting

I recently received a JSON response that includes dates that need to be formatted. Here is an example of the data:

{
    "webservice_status": {
        "status": "SUCCESS",
        "message": ""
    },
    "informationList": [{
        "TestNumber": "12",
        "Color": "RED",
        "dateOfPaint": "10242016",
        "location": "Wall"
    }, {
        "TestNumber": "13",
        "Color": "BLUE",
        "dateOfPaint": "10232016",
        "location": "Floor"
    }, {
        "TestNumber": "14",
        "Color": "GREEN",
        "dateOfPaint": "1052016",
        "location": "Wall"
    }, {
        "TestNumber": "15",
        "Color": "BLACK",
        "dateOfPaint": "10232016",
        "location": "Wall"
    }]
}

After attempting to use Moment.js to format the dates, I encountered an issue where the date was returning as Invalid Date. Here is the code snippet with the problem:

this.processJSON = function (data_, textStatus_, jqXHR_){
    var dateMoment = data_.informationList[0].dateOfPaint;
    console.log("The date we are testing:" + dateMoment);
    console.log(moment(dateMoment).format('MM/DD/YYYY'));
}

Given this situation, I am considering if it's possible to manually add slashes to the date string such as 10242016, transforming it into 10/24/2016, without using Moment.js. However, I would need to account for cases where the dates already have slashes and are in the correct format within the JSON response.

moment(String) function can handle strings that adhere to the ISO 8601 and RFC 2822 formats:

When converting a string into a moment object, it first checks if the string matches recognized ISO 8601 formats, then validates against the RFC 2822 date-time format. If neither match, it resorts to using new Date(string).

If your input string does not conform to a known format, you should specify the format when using the moment parser (moment(String, String)).

If you are uncertain about the exact format of an input string, but have some possible options, you can provide an array of formats.

For instance, if your data may include slashes ("/"), you can utilize moment(String, String[]) with ['MMDDYYYY', 'MM/DD/YYYY'] as the second parameter.

To display the value stored in the moment object, use the format() method. With format(), any invalid inputs like 1052016 will result in "Invalid Date," indicating inconsistencies (e.g., October does not have a 52nd day). You can verify the validity of the moment object representing a date/time by employing isValid().

Here is a practical example:

var data_ = {
    "webservice_status": {
        "status": "SUCCESS",
        "message": ""
    },
    "informationList": [{
        "TestNumber": "12",
        "Color": "RED",
        "dateOfPaint": "10242016",
        "location": "Wall"
    }, {
        "TestNumber": "13",
        "Color": "BLUE",
        "dateOfPaint": "10232016",
        "location": "Floor"
    }, {
        "TestNumber": "14",
        "Color": "GREEN",
        "dateOfPaint": "1052016",
        "location": "Wall"
    }, {
        "TestNumber": "15",
        "Color": "BLACK",
        "dateOfPaint": "10232016",
        "location": "Wall"
    }]
}

var processJSON = function (data_,textStatus_,jqXHR_){
  for(var i=0; i<data_.informationList.length; i++){
    var dateMoment =  data_.informationList[i].dateOfPaint;
    console.log("The date we are testing:"+dateMoment);
    console.log(moment(dateMoment, ['MMDDYYYY', 'MM/DD/YYYY']).format('MM/DD/YYYY'));
  }
}

processJSON(data_);

Answer №2

To transform the string "10242016" into a date format with slashes such as "10/24/2016", you can utilize the .replace() method along with a regular expression pattern like this:

var formattedDate = inputString.replace(/^(\d{2})(\d{2})(\d{4})$/, "$1"+"/"+"$2"+"/"+"$3");

Example:

var inputString =  "10242016";

var formattedDate = inputString.replace(/^(\d{2})(\d{2})(\d{4})$/, "$1"+"/"+"$2"+"/"+"$3");
console.log(formattedDate);
