How to set the valude after clear the variables

[nikhitha24]

Hi All,

I have written on change catalog client script to clear the value on the variable.

Example:

Before clear the value i have default values need to set for the variable.

I have written the catalog client script:

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

    if (isLoading || newValue == '') {

        return;

    }

    //alert(newValue);

    if (newValue == "other") {

        g_form.clearValue('request_number');

        g_form.clearValue('what_action_do_you_require');

        g_form.clearValue('change_record_number');

        g_form.clearValue('email_updates_and_final_report');

        g_form.clearValue('schedule_date_time_for_snapshot_creation');

        g_form.clearValue('schedule');

        g_form.clearValue('snapshot_retention_period');

        g_form.clearValue('catalog_item');

        g_form.clearValue('snapshot_change');

        g_form.clearValue('affected_ci');

    }

    else if(oldValue == "me") {

        g_form.clearValue('request_number');

        g_form.clearValue('what_action_do_you_require');

        g_form.clearValue('change_record_number');

        g_form.clearValue('email_updates_and_final_report');

        g_form.clearValue('schedule_date_time_for_snapshot_creation');

        g_form.clearValue('schedule');

        g_form.clearValue('snapshot_retention_period');

        g_form.clearValue('catalog_item');

        g_form.clearValue('snapshot_change');

        g_form.clearValue('affected_ci');

    }

}

After clear the values how can set the default values again.

 Please help me on this requirment

Hi @nikhitha24 

As per my lil knowledge, once a field value is clear it means the default value also get clear and now system will not use ootb default value. So you need to write script

May i know what is your exact use case

Hi @nikhitha24 you can set the default value inside the below function

if (newValue == '') {
g_form.setValue('fieldname','value'); // this value will be set when newValue is empty.
}
