How to create advance reference qualifier with if and else conditions

[rahul16]

I am using a variable set and I am filtering conditions like

Application<category<sub-category

if there is no application then category<sub-category

javascript&colon; 'u_type=category^u_inactive=false^u_catalog_item='+(current.cat_item.sys_id||current.request_item.cat_item.sys_id)+'^u_application='+current.variables.application;

This will work only if user select application

How can I use it if the application is empty set the application as empty?

if(current.variables.application){
return current.variables.application;
}else{
return '';
}

I created like this 

javascript&colon;if (current.variables.application != "") 'u_type=category^u_inactive=false^u_catalog_item='+(current.cat_item.sys_id||current.request_item.cat_item.sys_id)+'^u_application='+current.variables.application;else 'u_type=category^u_inactive=false^u_catalog_item='+(current.cat_item.sys_id||current.request_item.cat_item.sys_id);

but else part not working

Try returning something arbitrary in the else condition:

else{
return '....';
}

See if that works?

javascript&colon;if (current.variables.application != "") 'u_type=category^u_inactive=false^u_catalog_item='+(current.cat_item.sys_id||current.request_item.cat_item.sys_id)+'^u_application='+current.variables.application;else 'u_type=category^u_inactive=false^u_catalog_item='+(current.cat_item.sys_id||current.request_item.cat_item.sys_id);

You mean like this but else part not working

Usually, if there is dynamic condition involved,
1. you can create a script include
2. Pass the current object/cat item id into the parameter
3. build your if else condition in the script include function
4. return the filtered list of sys ids into your ref qualifier 

For ex: javascript&colon; new MyScriptInclude().getResults(current.sys_id);
and define your logic in the MyScriptInclude function.

You can try like this.

[rahul16]

var test = Class.create();

test.prototype = {

initialize: function() {},

getCategory: function(app) {

if (app) {

return "'u_type=category^u_inactive=false^u_catalog_item='+(current.cat_item.sys_id||current.request_item.cat_item.sys_id)+'^u_application='+current.variables.application";

} else {

return "'u_type=category^u_inactive=false^u_catalog_item='+(current.cat_item.sys_id||current.request_item.cat_item.sys_id)";

}

},

type: 'test'

};

javascript:new global.test().getCategory(current.variables.application);

I created like this but not working fine
