Need Help with Processing Script for RITM Cancel UI Page

Brett14 · ‎04-25-2017

All,

I have a requirement to add a cancel UI Action button to the RITM form that will open a window so that users can input cancel comments/reasons. Which I created and it works except for the Processing Script section of the UI Page.

I need the Processing Script to change the state & stage fields of the RITM and update the form. Which doesn't work at the moment. I have pasted my UI Page code below:

Any suggestions will help out. I haven't had to create many UI Pages within ServiceNow so I am a little stuck...

Client Script Section:

Processing Script Section:

Adding Script Include for anyone that runs past this post

Scrip Include:

Make sure you mark client callable

var cancelComments = Class.create();

cancelComments.prototype = Object.extendsObject(AbstractAjaxProcessor, {

cancelRITMComments: function(){

var sc_req_item_sys_id = this.getParameter('sysparm_sys_id');

var close_comments = this.getParameter('sysparm_close_comments');

var gr = new GlideRecord("sc_req_item");

if (gr.get(sc_req_item_sys_id)) {

gr.state = 4;

gr.close_notes = close_comments;

gr.stage = 'Request Cancelled';

gr.update();

}

return true;

},

_privateFunction: function(){ // this function is not client callable

}

});

UI Page Client Script (update):

function validateComments() {

//This script is called when the user clicks "OK" in the dialog window

//Make sure there are comments to submit

var comments = gel("dialog_comments").value;

comments = trim(comments);

if (comments == "") {

//If comments are empty, alert the user and stop submission

alert("Please enter your comments before submitting.");

return false;

}

var ritm_sys_id = gel("sc_req_item_sys_id").value;

var ajaxHelper = new GlideAjax('cancelComments');

ajaxHelper.addParam('sysparm_name', 'cancelRITMComments');

ajaxHelper.addParam('sysparm_sys_id', ritm_sys_id);

ajaxHelper.addParam('sysparm_close_comments', comments);

ajaxHelper.getXMLAnswer(function(){

GlideDialogWindow.get().destroy();

});

HTML Section of UI Page (update):

<g:evaluate var="jvar_ritm_sys_id" expression="RP.getWindowProperties().get('sys_id')" />

Hi Brett,

The variable name in your processing script must match the name in the input field in the HTML.

Change your processing script to reference sc_req_itemSysID on line 2 and you should be good.

Hi Chuck,

Thank you for replying. Processing script still doesn't set fields or redirect.

Am I actually setting it right in the HTML section with this input line?

Are you passing a URL argument called sysparm_sysID?

usually when I debug UI pages, I go to System Diagnostics> Debug Log

If I want to see what variables/values are available, I include this line in my HTML

<g:breakpoint />

and in the debug output at the bottom of the screen I can see that stuff (along with any errors). You might also just dump the variable out in the open in your HTML to see if it has a value. Something like:

<p>sysparm_sysID=${sysparm_sysID}</p>

Hi Check,

Thanks for the debug log tip:

It looks like url arguement is just pulling the sys_id. So I updated my HTML and processing script below and still doesn't work. First time with UI Pages and I didn't think it would be this difficult.

10:38:03 AM.801: #3924 /sc_req_item.do Parameters ------------------------- sys_id=ef4373ae13123200da9fb6d96144b0f5 sysparm_record_rows=75 sysparm_record_target=sc_req_item sysparm_record_list=active=true^ORDERBYDESCdue_date sysparm_record_row=1

var req = new GlideRecord('sc_req_item');

//req.get(sc_req_item_sys_id);

req.get(sc_req_item_sys_id);

req.state = 4;

req.stage = 'Request Cancelled';

req.update();

var urlOnStack = GlideSession.get().getStack().bottom();

response.sendRedirect(urlOnStack);
