JQuery .hasClass for multiple values in an if statement


I have a simple if statement as such:

if ($('html').hasClass('m320')) {

// do stuff 

}

This works as expected. However, I want to add more classes to the if statement to check if any of the classes are present in the <html> tag. I need it so it's not all of them but just the presence of at least one class but it can be more.

My use case is that I have classes (e.g. m320, m768) added for various viewport widths so I only want to execute certain Jquery if it's a specific width (class).

Here is what i have tried so far:

1.

if ($('html').hasClass('m320', 'm768')) {

// do stuff 

}

2.

if ($('html').hasClass('m320')) || ($('html').hasClass('m768')) {

 // do stuff 

}

3.

 if ($('html').hasClass(['m320', 'm768'])) {

 // do stuff 

    }

None of these seem to work though. Not sure what I am doing wrong but most likely my syntax or structure.


Solution

  • You just had some messed up parentheses in your 2nd attempt.

    var $html = $("html");
    
    if ($html.hasClass('m320') || $html.hasClass('m768')) {
    
      // do stuff 
    
    }
