How to open a catalog item with pre-populated variables from a portal "Create New" button?

[CharanV66187530]

Hello Community,

I have added a "Create New" button on my Service Portal. My goal is that when a user clicks this button, it opens a specific catalog item, and some variables on that item are automatically populated with predefined data.

Could someone please guide me on how to achieve this functionality? Specifically:

• How do I pass variable values when opening the catalog item from the portal?
• Is there a recommended way to implement this using URL parameters or client scripts?
• Any examples or best practices would be much appreciated.

Thank you in advance for your help!

Reference:
HTML :
<button ng-click="c.createNew()">Create New</button>

Server Script:

(function() {

  // Pass the URL to client script

  data.redirectUrl = "/sp?id=sc_cat_item&sys_id=67e2f2da4fff0200086eeed18110c7dd";

})();
Client Script:

api.controller = function() {

  var c = this;

  // The URL sent from server

  c.url = c.data.redirectUrl;

  // Function to open URL in new tab

  c.createNew = function() {

    window.open(c.url, '_blank');  // Opens URL in a new browser tab

  };

};

if you already included port_number in URL parameter then onLoad client script will fetch and set it

function onLoad() {

    var url = top.location.href;
    var portNumber = new URLSearchParams(url).get("port_number");
    g_form.setValue('variableName', portNumber);
}

Hi @Ankur Bawiskar , Please find the below scripts and I have attached two images. In 1st image we can able to get the object and showed in Infomessage but I couldn't able to send this response to client side getting undefined. Could you please help me on this?

Widget Side:

Server Script:

var sendSysID = record.getValue('sys_id');

    new global.checkRequestItemGlobal().getPortNumber(sendSysID);

Client Controller:

c.createNew = function() {

        var url = "/sp?id=sc_cat_item&sys_id=67e2f2da4fff0200086eeed18110c7dd";

        window.open(url);

    };

Script Include:

var checkRequestItemGlobal = Class.create();

checkRequestItemGlobal.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    getPortNumber: function(sysID) {

        var obj = {};

        var str;

        var gr = new GlideRecord('sc_req_item');

        gr.addQuery('sys_id', sysID);

        gr.query();

        if (gr.next()) {

            obj.portNumber = gr.variables.port_number.toString();

            obj.inbound = gr.variables.inbound_ip.toString();

            obj.outbound = gr.variables.outbound_ip.toString();

        }

        str = JSON.stringify(obj);

        gs.addInfoMessage("Response :" + str);

        return str;

    },

    type: 'checkRequestItemGlobal'

});

Onload Client Script:

function onLoad() {

    var ga = new GlideAjax('global.checkRequestItemGlobal');

    ga.addParam('sysparm_name', 'getPortNumber');

    ga.getXML(function(response) {

        var answer = response.responseXML.documentElement.getAttribute("answer");

        var result = JSON.parse(answer);

        alert(result);

        alert("portNumber :" + result.portNumber);

        alert("inbound :" + result.inbound);

        alert("outbound :" + result.outbound);

        g_form.setValue('port_number', result.portNumber);

        g_form.setValue('inbound_ip', result.inbound);

        g_form.setValue('outbound_ip', result.outbound);

    });

}
