g_form.getParameter('sysparm_id'); not supported in service portal

[ARNAB3]

_form.getParameter('sysparm_id'); - not working in portal  what should be  the  alternate way to prevent error in portal.

function onChange(control, oldValue, newValue, isLoading) {

if (isLoading ) {
return;
}

var item = g_form.getParameter('sysparm_id');
var bf = g_form.getValue('business_function');
g_form.clearOptions('u_short_description');
if (newValue == '') {return;}

var encoded = 'u_active=true^u_catalog_item='+item+'^u_business_function='+bf+'^u_subcategory='+newValue;
var tablename = 'u_bs_to_it_field_level_routing';
// now bring back every row in the table that matches our criteria
var roleData = new GlideAjax('DataAjaxUtil');
roleData.addParam('sysparm_name','getResultSet');
roleData.addParam('sysparm_encoded_query',encoded);
roleData.addParam('sysparm_table_name',tablename);
roleData.getXMLWait();
var roleArr = roleData.getAnswer();
if (!roleArr)
return;
roleArr = JSON.parse(roleArr);
var opt = [];
g_form.setDisplay('u_short_description' , true);
g_form.setMandatory('u_short_description' , true);
g_form.addOption('u_short_description', "", " --None-- ");
//now get a unique listing of these short descriptions
for (var i = 0; i < roleArr.length; i++) {
if (opt.indexOf(roleArr[i].u_short_description) == -1) {
opt.push(roleArr[i].u_short_description);
}
}
// now sort them and present them in the drop down choices.
opt.sort();
for ( i = 0; i < opt.length; i++) {
g_form.addOption('u_short_description' , opt[i] , opt[i]);
}
}
