fields.errorText

Error message to display when a field is in error.
Please note - this property requires the Editor extension for DataTables.

Description

This string is used when a field is found to be invalid via HTML 5 validation attributes or true is passed to field().error()

Unlike with server-side validation where specific strings can be given for each validation constraint, this should be given as a generic message for the field, describing what input is required for the field to be valid, as only a single error message can be shown via this method.

It is also important to highlight that in addition to client-side validation, you must use server-side validation, since client-side validation can easily be bypassed.

Type

This option can be given in the following type(s):

• string

Example

const editor = new DataTable.Editor({
	ajax: 'php/staff.php',
	table: '#myTable',
	fields: [
		{
			label: 'Extension:',
			name: 'extn',
			attr: {
				min: 1000,
				max: 5000,
				required: true,
				type: 'number'
			},
			errorText: 'Extension number must be between 1000 and 5000'
		}
	]
});
