Index Required Field Text For Free

It is a common technique to add an asterisk * to a form control's label. Then, somewhere else on the page, for example below the form, this asterisk is explained to indicate a required input (in allusion to foot notes in text documents).

In the Navigation Pane, right-click the table and then click Design View. Select the field that you want to require always has a value. In the Field Properties pane, on the General tab, set the Required property to Yes.

How to indicate a required field Provide the required text in the label. Provide a graphic * image in the label with appropriate alt text. Providing a star (asterisk) symbol. Use of color to identify if a form control is required. Providing HTML5 and ARIA required attributes.

Click the Field Name for the field that you want to index. Under Field Properties, click the General tab. In the Indexed property, click Yes (Duplicates OK) if you want to allow duplicates, or Yes (No Duplicates) to create a unique index. To save your changes, click Save on the Quick Access Toolbar, or press CTRL+S.

# Set the "required" Attribute using JavaScript Select the element. Use the setAttribute() method to set the required attribute. The setAttribute method will add the required attribute to the element.

To customize the error message using JavaScript, we can use the "setCustomValidity" method, which allows us to specify a custom error message for the input field.

The simplest HTML validation feature is the required attribute. To make an input mandatory, add this attribute to the element. When this attribute is set, the element matches the :required UI pseudo-class and the form won't submit, displaying an error message on submission when the input is empty.
