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

try this one

if ($("#checkSurfaceEnvironment-1:checked").length>0) {
    //your code in case of NOT checked
}

In Above code selecting the element by Id (#checkSurfaceEnvironment-1) then filter out it's checked state by (:checked) filter.

It will return array of checked element object. If there any object exists in the array then if condition will be satisfied.
