Comments field mandatory in service portal

vaibhavdesai · ‎04-03-2017

Hello Experts,

I am quite new to service portal and trying to achieve one scenario. When Incident is in resolved state "Reopen Incident" button/widget should be visible and on click of that comments should be mandatory.

I am able to create widget and add required actions in it. But, I am not able to understand how to make comments mandatory.

Below is the code.. Help is much appreciated!!

HTML

----------------------------------------

<div class="panel-heading">Actions</div>

<button type="button" class="btn btn-primary btn-block" ng-click="c.uiAction('reopen')">Reopen Incident</button>

</div>

----------------------------------------

Client Script

----------------------------------------

function() {

var c = this;

c.uiAction = function(action) {

c.data.action = action;

c.server.update().then(function() {

c.data.action = undefined;

})

}

----------------------------------------

Server Script

----------------------------------------

(function() {

// Get table & sys_id

data.table = input.table || $sp.getParameter("table");

data.sys_id = input.sys_id || $sp.getParameter("sys_id");

// Valid GlideRecord

gr = new GlideRecord(data.table);

if (!gr.isValid())

return;

// Valid sys_id

if (!gr.get(data.sys_id))

return;

if (input && input.action) {

var action = input.action;

var onBehalfOf = gr.getValue('u_on_behalf_of');

var caller = gr.getValue('caller_id');

var currentUser = gs.getUserID();

//var comments = gs.getValue('comments');

//var comments = gr.getValue('comments');

//var comments = $sp.getValue('comments');

gs.addInfoMessage('comments '+comments);

if(data.table == 'incident'){

if (action == 'reopen') {

if(onBehalfOf == currentUser || caller == currentUser){

if(comments != ""){

gr.setValue('comments',comments);

gr.setValue('state', -1);

gr.update();

}

else{

//Making Comments mandatory code

gs.addErrorMessage('Adding information in Additional Comments is mandatory')

}

} else {

}

})();

----------------------------------------

Hi Vaibhav,

From your picture, it seems you are defining the "comments" field in one widget, and trying to get its value from the "reopen incident" widget. You cannot retrieve fields from another widget directly, but you need to communicate your widgets somehow.

Take a look at How to communicate between widgets in Service Portal

A simple solution for your case would be to use the ng-change attribute in the text field of the comments field in the first widget, such that it broadcast the value. For example:

HTML:

client script:

function() {

var c = this;

c.broadcastComment = function(){

$rootScope.$broadcast('comments', c.data.comments);

}

Then, in the reopen incident widget, you can listen the event it is propagated when the comments change, by just adding

function() {

var c = this;

/* your existing code here */

$rootScope.$on('comments', function(event,data) {

c.data.comments = data;

});

}

This would insert the comments coming from the other widget into the data, such that in the server side, you can get the comments value by just using

var comments = input.comments;

Hope it helps.

Ginés.

Hi Vaibhav,

It cannot see that you set the c.data.state value anywhere in the server side, therefore it will not be available in the client either. You need to set the field data in the server so it is available in the client.

For example, if in the server you set

data.myVar = "123";

in the client/HTML, you can access c.data.myVar and will contain the value "123".

In your case, you just need to add this line after getting the GlideRecord, but outside the "if (input ...)" checking

data.state = gr.getValue('state');

I mean, your server code should look like

(function() {

...

// Valid sys_id

if (!gr.get(data.sys_id))

return;

data.state = gr.getValue('state');

if (input && input.action) {

...

}

})();
