Javascript to Retrieve/Set Field Values on Load

Posted on by Community Member

Hi All,

I'm running into an issue and I can't seem to find a solution. I am attempting to create some Javascript that will run on form load, compare two dates, and populate an option set, but everything I try spits out:

I've tried multiple different ways to write the script, and below is how it currently sits. My Javascript is a little rusty, and any help that anybody can offer would be much appreciated.

Version: On-Premise 2013

Activity:

Compare date in a field against today's date, and populate an option set with 'Yes' (value 100000000) if it is within 4 days.

Javascript:

function CalcDaysDifference()

{

var today = new Date();

var lastAction = Xrm.Page.getAttribute("LastActionDate").getValue();

if(lastAction != NULL)

{

if (today - lastAction <= 4)

{

xrm.page.getAttribute("LastActionWithin4Days").setValue(100000000);

}

Hi

What is the issue you are facing. The general practice is first get the Attribute (Xrm.Page.getAttribute("LastActionDate")) and ensure it is not null & not undefined and then use .getValue() of it.

And the if condition should be if((today-lastaction)/(1000*60*60*24)<=4) ==> Javascript date difference with simple Minus (-) will return in Milli seconds, so you have to convert that in to dates. Probably thats why your code always showing condition passed.

Note: You might need to convert your "lastAction" to new Date before you start the if conditon.

Happy coding :)

var LastActionDate = Xrm.Page.getAttribute('LastActionDate').getValue();

    var millisecondsPerDay = 1000 * 60 * 60 * 24;

    var millisBetween = LastActionDate.getTime() - today.getTime();

    var NoOfdays = millisBetween / millisecondsPerDay;

    if (NoOfdays < 4)

xrm.page.getAttribute("LastActionWithin4Days").setValue(100000000);

Try this code
