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!

You can use clearClientData()

So, after you set the values on form load, add lines like this to your script:

g_user.clearClientData('number');

g_user.clearClientData('short_description');

g_user.clearClientData('description');

If this was helpful or correct, please be kind and click appropriately!

Thank you for reply. But that script not working in catalog client script for me. I have tried it before but its show error message when i open catalog item "there is javascript error on your browser console" and the data still shown altough im not click ui action from incident. So i need to clear the session. Or you have other advice how to copy value from incident to catalog variables trough ui action?

Hmm sorry about that. Try setting the values to null once you pull them instead.

g_user.setClientData('number', null);

g_user.setClientData('short_description', null);

g_user.setClientData('description', null);

That seems to work in my PDI.

If this was helpful or correct, please be kind and click appropriately.

I hope this helps!

Nope, sorry, doesn't seem to work with a catalog item.

Works like a charm on a table form, but seems to do nothing in the catalog - not even throw an error.

I hope this helps!
