Validating a checkbox using javascript Chat with adult free of cost

16-Nov-2019 21:01

A radio button allows the user to select only one option so Javascript should display a message only if none of the radiobuttons are selected.

In the case of a checkbox multiple values can be selected so validation is done if none of the checkboxes are ticked.If not, an alert is displayed and focus is moved to the checkbox.Not the prettiest solution, but functional in all browsers with Java Script enabled.I have some checkboxes in a form that I'd like to validate (check to ensure that at least one has been ticked): I need to pass along multiple checkbox responses to my PHP script and therefore need to keep checkboxes named name="response[]".When I do this, I get the error "document.surveyform.response has no properties" Any idea what change I can make to the javascript so that I can name my checkboxes name="responses[]" ?

You can also validate by requiring the user to select a minimum of one value or two value according to your requirement.
