How to clear session data after submit catalog item?

zulhiyatiuwi · ‎01-19-2020

Hello... I have UI action that save session data of number, short description and description of incident that i want to add to request variables

UI Action:

var session = gs.getSession();
session.putClientData('number', current.sys_id);
session.putClientData('short_description', current.short_description);
session.putClientData('description', current.description);

url="sp?id=sc_cat_item&sys_id=f959c1fa2f5a4010151e877cf699b6a9&sysparm_category=d258b953c611227a0146101fb1be7c31";

action.setRedirectURL(url);

And i have catalog client script in item:

function onLoad() {
    //Type appropriate comment here, and begin script below
    if (null != g_user.getClientData('number')) {
        var num = g_user.getClientData('number');
        g_form.setValue('incidentnum', g_user.getClientData('number'));
        var sd = g_user.getClientData('short_description');
        g_form.setValue('subjek', num);
        var desc = g_user.getClientData('description');
        g_form.setValue('deskripsi', desc);
    }
}

Its work, but how can i clear data session after i click the UI Action? I need to clear data after form request is load so, when i open the same form, the data will be empty. Please help. Thank you

Ok, the only way I can seem to get this to work in a Catalog Item is to do it via a GlideAjax call (basically just shifting this from client-side to server side). I made a quick script include that looks like this:

name: clientData
client callable: checked. 

var clientData = Class.create();
clientData.prototype = Object.extendsObject(AbstractAjaxProcessor, {
	type: 'clientData',
	clearData: function() {
		
		var session = gs.getSession();
		session.clearClientData('number');
                session.clearClientData('short_description');
                session.clearClientData('description');
		return 'clientData Cleared';
	},
	
});



And then in a client script call:

var ga = new GlideAjax('clientData');
ga.addParam('sysparm_name', 'clearData');
ga.addParam('sysparm_id', g_form.getValue('ref_server_name'));
ga.getXML(procResponse);

function procResponse(response) {
var answer = response.responseXML.documentElement.getAttribute("answer");
//indicate the response in the console
jslog(answer);
}

I hope this helps!

I dont like the solution with the session.

Here is how I do it ...

// Business Rule on Display

g_scratchpad.link = '';

// Get the instance name
var instanceName = gs.getProperty('instance_name');

// Check if necessary fields are set
var sysId = current.sys_id;
var user = current.assigned_to.sys_id;

// Construct the full URL in one go
g_scratchpad.link = 'https://' + instanceName + '.service-now.com/XXXX_WHERE_EVER_U_WANT_TO_GO_XXXXX&sys_id=' + sysId 
    + '&sys_param_type=link' 
    + '&sys_param_srn_user=' + user;

// UI Action
    var url = g_scratchpad.link; 
    getTopWindow().popupOpenFocus(url, "_self", null, null, "");

// on load client script

var parmLink = getParmVal('sys_param_type') || '';
g_scratchpad.prefillUser = getParmVal('sys_param_srn_user') || '';

if (parmLink === 'link' && g_scratchpad.prefillUser.toString() !== '') {
    g_form.setValue('assigned_to', g_scratchpad.prefillUser);
}

function getParmVal(name) {
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regexS = "[\\?&]" + name + "=([^&#]*)";
    var regex = new RegExp(regexS);
    var results = regex.exec(top.location);
    return results == null ? "" : decodeURIComponent(results[1]).toString();
}

Quite Flexible and could be done in a generic way to that you could handle multiple use cases within one BR / UI Action / CS ...

Hi,

May I know where did you get ref_server_name in this line?

ga.addParam('sysparm_id', g_form.getValue('ref_server_name'));

Thank you!
