Question

What would be the correct regex to check wether a checkbox is checked in javascript?

update: i know it is usually not done with a regex. But since its part of a form module and all the validations are done with a regex. I thought this could also be checked with a regex. My quyestion is how.

Answer 1

You really just want to access the checked property. (Truly, regex has no place here – it should be used only with lack of anything better.)

Try this:

var checkbox = document.getElementById("myCheckbox");
if (checkbox.checked)
{
    alert("Checkbox is CHECKED.");
}
else
{
    alert("Checkbox is UNCHECKED.");
}
