Hi ,

Please use the below URL to achieve this.

Get Date and Time Client Script

[Ankur Swami]

REspective code is written below:

Client script:

var cdt = g_form.getValue('due_date'); //First Date/Time field
var dttype = 'second'; //this can be day, hour, minute, second. By default it will return seconds.

var ajax = new GlideAjax('ClientDateTimeUtils');
ajax.addParam('sysparm_name','getNowDateTimeDiff');
ajax.addParam('sysparm_fdt', cdt);
ajax.addParam('sysparm_difftype', dttype);
ajax.getXML(doSomething);

function doSomething(response){
var answer = response.responseXML.documentElement.getAttribute("answer");
alert(answer);
if(answer > 604800 )
{
g_form.setMandatory('fieldname',true);
}
}


Script include:

var ClientDateTimeUtils = Class.create();
ClientDateTimeUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {
//Takes a Single Date/Time Field and returns its time difference from nowDateTime().
//params = sysparm_fdt (the first date/time field), sysparm_difftype (time based format to return result. See "_calcDateDiff" function comments)
getNowDateTimeDiff: function(){
var firstDT = this.getParameter('sysparm_fdt'); //First Date-Time Field
var diffTYPE = this.getParameter('sysparm_difftype'); // Date-Time Type to return the answer as. Can be second, minute, hour, day
var diff = gs.dateDiff(gs.nowDateTime(), firstDT, true);
var timediff = this._calcDateDiff(diffTYPE, diff);
//return "getNowDateTimeDiff: FIRST DT: " + firstDT + " -DIFFTYPE: " + diffTYPE + " -TIME DIFF: " + timediff;
return timediff;
},

//Private function to calculate the date difference return result in second, minute, hour, day.
_calcDateDiff: function(diffTYPE, seconds){
var thisdiff;
if (diffTYPE == "day"){thisdiff = seconds/86400;}
else if (diffTYPE == "hour"){thisdiff = seconds/3600;}
else if (diffTYPE == "minute"){thisdiff = seconds/60;}
else if (diffTYPE == "second"){thisdiff = seconds;}
else {thisdiff = seconds;}
return thisdiff;
}


});

OOB there is no g_form method to get the current date/time in client side

you will have to use javascript Date class

This is how it can be done in client script

Script:

var today_date = new Date();
var today_date_time = formatDate(today_date, g_user_date_time_format);
alert(today_date_time);
