ServiceNow introduction to GlideForm API | ServiceNow Client scripts | ServiceNow JavaScripts – 4

Hi There,

I hope you’re doing great.

With the participation in the ServiceNow Javascripting Challenge led by [@Gagan Jolly](https://www.servicenow.com/community/user/viewprofilepage/user-id/248249), I m learning a lot. I thought I should share my learning on the Now community also

### **Day 6-9: ServiceNow Java scripting Challenge**

### **Statement of Work :**

**Write a code using the following methods**

1. ShowFieldMessage()
2. **hideAllFieldMsgs()**
3. **hideRelatedList(String listTableName)**
4. **isMandatory(String fieldName)**
5. **isNewRecord()**
6. **isSectionVisible(String sectionName)**
7. **removeOption(String fieldName, String choiceValue)**
8. **save()**
9. **setLabelOf(String fieldName, String label)**
10. **setMandatory(String fieldName, Boolean mandatory)**
11. **setReadOnly(String fieldName, Boolean readOnly)**
12. **showRelatedLists()**
13. **submit()**

### **Solution :**

Let’s first try to understand what ServiceNow GlideForm API means

**GlideForm :**

– The GlideForm API provides methods to customize forms.
– Works on the client side only

– Return : void
2. **hideAllFieldMsgs()**
– Hides all field messages.
– Method signature : **hideAllFieldMsgs()**
– Input parameters : void
– Return : void
3. **isNewRecord()**
– Returns true if the record has never been saved.
– Method signature : **isNewRecord()**
– Input parameters : void
– Return : Boolean =Returns true if the record has not been saved; otherwise false.
4. **isSectionVisible()**
– Returns true if the section is visible.
– Method signature : **isSectionVisible(String sectionName)**
– Input parameters : String =Section name
– Return : Boolean =Returns true when the section is visible; otherwise, false is returned.

– choiceValue = String = The value stored in the database. This is not the label.
– Return : void
6. **save()**
– Saves the record without navigating away (update and stay).
– Method signature : **save()**
– Input parameters : void
– Return : void
7. **setLabelOf()**
– Sets the plain text value of the field label.
– Method signature : **setLabelOf(String fieldName, String label)**
– Input parameters :
– fieldName = String = The field name.
– label =String = The field text label.
– Return : void
8. **setMandatory()**
– Makes the specified field mandatory.
– Method signature : **setMandatory(String fieldName, Boolean mandatory)**
– Input parameters :
– fieldName = String = The field name.
– mandatory = Boolean ==When true makes the field mandatory.
– Return : void
9. **setReadOnly()**
– Makes the specified field read-only or editable.
– Method signature : **setReadOnly(String fieldName, Boolean readOnly)**
