How to populate the current date/time on a field using client callable UI Action?

[User177031]

Hi All,

I am trying to populate the current date/time on field using client callable UI Action.

I am having a UI action 'Create Meeting'. When user click on the button, the meeting form will open and it should have the current date/time as 'u_start_date' & add 1hr from current time as 'u_end_date'. Below is the code I am trying.

function openFormDialog() {
var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1; //January is 0!
var yyyy = today.getFullYear();
var tt = new Date().getTime();
alert(tt);
if(dd<10){
dd='0'+dd;
}
if(mm<10){
mm='0'+mm;
}
var toy = dd+'/'+mm+'/'+yyyy;
alert(toy);

var gModalForm = new GlideModalForm('Create Meeting', 'u_meetings');
gModalForm.setPreference('sysparm_view', 'new');
gModalForm.addParm('sysparm_query', 'u_customer_account = ' + g_form.getUniqueValue() + '^u_start_time =' + toy);
gModalForm.setCompletionCallback(function(action_verb, sys_id, table, displayValue) {
});
gModalForm.render();
}

- Thank you.

try with glide ajax. 

sample code. 

Client script:

var ajax = new GlideAjax('ClientDateTimeUtils');
ajax.addParam('sysparm_name','getNowDateTime');
ajax.getXML(doSomething);

function doSomething(response){
var answer = response.responseXML.documentElement.getAttribute("answer");
alert(answer);


Script Include:

var ClientDateTimeUtils = Class.create();
ClientDateTimeUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {

//Returns the Date/Time of right now.
getNowDateTime: function(){
var now = gs.nowDateTime(); //Now Date/Time
return now;
},

});

Hi Harsha,

But I want the date/time to be populated through client callable UI action only. Can you please help?

- Thank you.

you just have to use glide ajax inside your client callable ui action , that will work.
