Important ServiceNow Script or Reference

ServiceNow Best Practice :




Attachment script Attachment Mandatory --- 




function onSubmit() {

    if (g_form.getValue('non_tracked_devices') == 'Yes') {
        var cat_id = g_form.getValue('sysparm_item_guid');
        var gr = new GlideRecord("sys_attachment");

        gr.addQuery("table_sys_id", cat_id);
        gr.query();
        if (!gr.next()) {
            alert("You must add an attachment before submitting this request.");
            return false;
        }
    }

}

//Script to Delete multiple record 

var psc = new GlideRecord('<table_name>'); //Make sure table name is correct
psc.addEncodedQuery('sourceISNOTEMPTY');// Encoded Query or Filter if any required 
psc.addQuery('sourceISNOTEMPTY');//Query or Filter if any required 
psc.setLimit('10'); //Limit number of records 
psc.setWorkflow(false); //Turn off business rule or notifications
psc.deleteMultiple();



//On Change Client script Example ...   Disable or Enable the form

Remove Middle name from a name in Excel Sheet .

Using formula may be a very easy way for most of Excel users.

Select a blank cell next to the name list, and type this formula =TRIM(LEFT(A1,FIND(" ",LOWER(A1),1))) & " " & TRIM(MID(A1,FIND(" ",LOWER(A1),FIND(" ",LOWER(A1),1)+1)+1,LEN(A1)-FIND(" ",LOWER(A1),1)+1)) into it, then press Enter button on the keyboard and drag the Auto Fill handle to fill the range needed to apply the formula. Now you can see all the name of the list are shown in the new column without middle initials.

// Get all the incidents updated 3 days before

var dupRecords = [];
var count = '';
var gr = new GlideRecord('incident');
gr.addQuery('sys_updated_onRELATIVEGE@dayofweek@ago@3');
gr.query();
while(gr.next()){
dupRecords.push(gr.number);
}
gs.print(dupRecords);
