If a set of checkboxes have the same name the HTML form encoding is different to those with different names.

In this article, we are given an HTML document having one checkbox and a group of checkboxes and the task is to toggle between them with the help of JavaScript. We can achieve this by using the event onChange() which is triggered whenever we check or uncheck the checkbox.

Using Vertical-align Property The checkbox is by default aligned to the baseline of the text of the label in some modern browsers. However, to ensure their proper alignment we can set the vertical-align property to “top” for both the label and input element.

Zend\Form\Element\MultiCheckbox is meant to be paired with the FormMultiCheckbox for HTML inputs with type "checkbox". This element adds an InArray validator to its input filter specification in order to validate on the server if the checkbox contains values from the multiple checkboxes.

When setting multiple values for a checkox property, the values should be separated with a semicolon (;).

Multiple Checkbox Validation in Javascript In the above example, multiple checkboxes are validated by using an array of checkboxes. The options in the checkboxes are stored as an array called options. The querySelectorAll method is used to select all the checkbox elements from the DOM.

Method 1: By making the position of checkbox relative, set the vertical-align to the middle can align the checkboxes and their labels. Here, we have made the position of the checkbox relative to the label. So the checkboxes are aligned ing to the label.

The Input Checkbox name property in HTML DOM is used to set or return the value of name attribute of a input checkbox field. The name attribute is required for each input field. If the name attribute is not specified in an input field then the data of that field would not be sent at all.
