javascript - "else if" is not working in jQuery? - Stack Overflow

programmeradmin6浏览0评论

I have written an if statement in jQuery.

My code:

if($('#customer0').checked())
{
  $('#shop').fadeOut();
}

else if($('#customer1').checked())
{
  $('#shop').fadeIn();
}

else ($('#customer2').checked())
{
  $('#shop').fadeOut();
};

When I have if (custmer0) and else (customer1) the fadeOut and fadeIn work good. But when it's customer2 (that is else statement) it is not working? What is wrong?

Reset to default 5

else doesn't take any parameters. The code below is more applicable:

if($('#customer0').checked()) { $('#shop').fadeOut(); }
else if($('#customer1').checked()) { $('#shop').fadeIn(); }
else if($('#customer2').checked()) { $('#shop').fadeOut(); };

On your third else

Change

else ($('#customer2').checked())

to

else if ($('#customer2').checked())

fix you parens:

if ($('#customer0').checked()) {
    $('#shop').fadeOut();
}

else {
    if ($('#customer1').checked()) {
        $('#shop').fadeIn();
    }

    else {
       if($('#customer2').checked()) {
          $('#shop').fadeOut();
       }
    }
}

The reason why you code want working is the if statement was taking the wrong else for when the if statement is false

Also you cannot have params for an else statement

First off, the syntax for getting the value of a checkbox is:

$('#customer0').attr('checked')

Second, else statements don't have (statement) after them, you need to use a else if.

if($('#customer0').attr('checked'))
{
  $('#shop').fadeOut();
}

else if($('#customer1').attr('checked'))
{
  $('#shop').fadeIn();
}

else if($('#customer2').attr('checked'))
{
  $('#shop').fadeOut();
}
