jQuery验证输入类型复选框的值

Question

I'am stoked at a basic task. I want to check if a checkbox i checked or not using jQuery.

The problem is that the if condition is being executed no matter its checked or not.

What am I doing wrong?

($('#betingelser').prop('checked', false)){
    console.log("checked if");
    isValid = false;
    result += 'Venligst accepter betingelserne<br>';        
}

Thanks for your time

Answer 1

You are not having correct condition in if part. you are setting the value as false by using $('#betingelser').prop('checked', false) in it. To check whether checkbox is check use:

if($('#betingelser').is(':checked')){
   //rest code
}

Answer 2

By passing false as the second argument, you're actually telling the checkbox to check itself. Just delete this second argument and it should work fine.
