Catalog Client Script not setting the reference variable using URL parameter (value keeps reverting)

[SwethanaB]

Hi team,

I’m working on a Catalog Client Script (onLoad) where I need to populate a reference variable (configuration_item) based on a URL parameter ci=1.

https://<instance>.service-now.com/<catalog_page>?id=sc_cat_item&sys_id=(sys id of CI)&ci=1

OnLoad script:

function onLoad() {

    var ci = g_form.getParameter('ci');

    g_form.clearValue('configuration_item');

    if (ci === '1') {

        g_form.setValue('configuration_item', 'sys_id');

    }

}

The variable still loads the previously used value, even after clearValue().

Hello @SwethanaB ,

try this script :

function onLoad() {
   var ci= getParameterValue('ci');
   if(ci == '1'){
      g_form.clearValue('configuration_item');
      g_form.setValue('configuration_item','sys_id');
   }
}
 function getParameterValue(name) {
        var url = top.location.href;
        var value = new URLSearchParams(url).get(name);
        if (value) {
            return value;
        }
    }

If my response helped mark as helpful and accept the solution.
