Form Radio Notice For Free

If a radio button is checked, its checked property is true . Then, we assign the value of the selected radio button to the selectedSize variable. Since only one radio button in a radio group can be checked at a time, the loop is terminated immediately by the break statement.

To check which radio button is selected in a form, we first get the desired input group with the type of input as an option and then the value of this selection can then be accessed by the val() method. This returns the name of the option that is currently selected.

The checkbox is shown as a square box that is ticked (checked) when activated. Checkboxes are used to let a user select one or more options of a limited number of choices. Tip: Always add the <label> tag for best accessibility practices!

We can do this by providing the radio's ID attribute value in the for attribute of the <label> element. Now, you can click the associated label to select the corresponding radio button. If your radio button doesn't have an id attribute, you can wrap the radio button directly inside the <label> element.
