Summary

For dates that need to be dynamically selected, for example, always select a date 37 days in the future, some script customization is required. This is often seen on travel-related sites where from and to dates are needed.

Solution

The following JavaScript code snippet can be modified to perform Dynamic Date Selection in a browser clickpath synthetic monitor.

var now = new Date();
var today = new Date(now.getFullYear(), (now.getMonth()), now.getDate());
var oneMonthLater = new Date(today.valueOf() + 30*1*24*60*60*1000); //30 days later from the current date
api.info(oneMonthLater); 

var ReturnDate = new Date(today.valueOf() + 37*1*24*60*60*1000);
api.info(ReturnDate); //37 days later from the current date

function monthConverter(month){     switch(month){         case 0: return '01';         case 1: return '02';         case 2: return '03';         case 3: return '04';         case 4: return '05';         case 5: return '06';         case 6: return '07';         case 7: return '08';         case 8: return '09';         case 9: return '10';         case 10: return '11';         case 11: return '12';     } }


var startMonth = monthConverter(oneMonthLater.getMonth());
var startDay = ("0" + oneMonthLater.getDate()).slice(-2);
var startYear = oneMonthLater.getFullYear();
var returnMonth = monthConverter(ReturnDate.getMonth());
var returnDay = ("0" + ReturnDate.getDate()).slice(-2);
var returnYear = ReturnDate.getFullYear();
var departDate = startYear  + "-" + startMonth+ "-" + startDay;  // change the variable order format and delimiter based on your input filed based on your date format for both departDate & returnDate variables. In this example date format is dd-mm-yyyy
var returnDate = returnYear  + "-" + returnMonth + "-" + returnDay; 
api.info(departDate);
api.info(returnDate);
function triggerevent(element) {
    var evt = document.createEvent("MouseEvent");
    var eventType = ["input", "change"];
    for (i = 0; i < eventType.length; i++) {
        evt.initMouseEvent(eventType[i], true, true, window);
        element.dispatchEvent(evt);  } }

var element1 = document.querySelector("#From"); // Replace with From input field JS Path
var element2 = document.querySelector("#To");   // Replace with To input field JS Path
element1.value = departDate;
triggerevent(element1);
element2.value = returnDate;
triggerevent(element2);

Steps to update and use the JavaScript snippet

Go to the relevant page on Chrome browser
Right click on the From & To Date input elements which you want to perform the dynamic date selection on the page-> Inspect the element which will open the developer tools
Right click on the element on the Web developer tools - > Copy - > Copy JS path of both From & To Date input elements
Paste the JS path on the below element1 & element2 value and add this JavaScript code into the JavaScript Event of your Browser click path monitor which will enter the Dynamic Date on From & To input fields as shown in the below image,

Note:- Change the departDate and returnDate variable assigned order format and delimiter based on your input filed date format. In this example date format is dd-mm-yyyy
