Hi Everyone,

I have an requirement that, I need to send the data from server side to HTML check box. Based on server side data, i need to show the checkbox field either true or false. I have tried with using below data and unable to fetch and show the data in service portal. Please check below code and correct me.

HTML Code:

<div >
<label><input type="checkbox" ng-model="chkbx" ng-checked="data.u_customfield" ng-click="checkNotify(chkbx)" ng-checked="false"> testing</label>
</div>

Server side:

var gr_notify = new GlideRecord('sys_user');

gr_notify.addQuery('sys_id', gs.getUserID());

gr_notify.query();

if(gr_notify.next())

{

var u_customfield = gr_notify.u_customfield;

}

data.u_customfield = u_customfield;

Could you please help me, how to show check box field either true or false based n response from server side?

Thank you.

Hi @suresh91

This should work:

HTML:

<div >
<label><input type="checkbox" ng-model="chkbx" ng-checked="data.u_customfield" ng-click="c.checkNotify(chkbx)"> testing</label>
</div>

Client:

api.controller=function($scope) {
	/* widget controller */
	var c = this;


	c.checkNotify = function(val) {


		c.data.action = "getField";
		c.data.value =  val;


		alert("test Before " + val);

		c.server.update().then(function(response){
			alert("test After " + response.u_customfield);

		})
	}
}

Server:

(function() {

	if (input){
		if (input.action == "getField"){
			var gr_notify = new GlideRecord('sys_user');
			gr_notify.addQuery('sys_id', gs.getUserID());
			gr_notify.query();
			if(gr_notify.next())
			{
				gs.addInfoMessage(gr_notify.getDisplayValue())
				data.u_customfield = gr_notify.u_customfield;
				return data;
			}
		}
	}

})();

Hi Dutta,

Thanks for your response.

I did the change but still not getting value. I tried to add info message like below and it showing value in portal

gs.addInfoMessage("testing record value---------->"+data.u_customfield);

Hi @suresh91

Can you try declaring variable outside if condition like below :

/*Declare variable here*/
var u_customfield;

var gr_notify = new GlideRecord('sys_user');
gr_notify.addQuery('sys_id', gs.getUserID());
gr_notify.query();
if(gr_notify.next())
{
/*initialize here*/
  u_customfield = gr_notify.u_customfield;
}
data.u_customfield = u_customfield;
