jQuery: Test if checkbox is NOT checked

Question

I\'m having trouble figuring this out. I have two checkboxes (in the future will have more):

• checkSurfaceEnvironment-1
• checkSurface

Answer 1

I think the easiest way (with jQuery) to check if checkbox is checked or NOT is:

if 'checked':

if ($(this).is(':checked')) {
// I'm checked let's do something
}

if NOT 'checked':

if (!$(this).is(':checked')) {
// I'm NOT checked let's do something
}
