If body class equals X then do something?

Question

I have this code running from an external script for an image slider for every page on a site.

$(document).ready(function() {
  $("#slideshow").show();
  $('#slider1').anythingSlider({
    buildNavigation: false,
    delay: 8000
    })

On one of the pages I don't want the image slider to rotate automatically so I need to add an extra variable. I've put a class on the body of the page and want to do something along the lines of...

If the body has a class of 'partnerCharitiesDetail' then run this script instead of the generic one

This is what I have tried below (without success). I have 2 questions really,

1) What happens in jQuery when there are 2 identical scripts running (like this example), will it overwrite the older one with the newer one?

2) Where am I going wrong?! Is my approach the best way to do it?

$(document).ready(function() {
 $("#slideshow").show();
  $('#slider1').anythingSlider({
    buildNavigation: false,
    delay: 8000
  })

  if ($('body.partnerCharitiesDetail').length > 0){
  $('#slider1').anythingSlider({
  buildNavigation: false,
  delay: 8000,
  startStopped: false
 }) 
}

Thanks!

Use the hasClass() method to check if an element has a certain class.

Also, your code is a little repetitive (and could even cause AnythingSlider to run twice) — I would write it like this instead:

$(document).ready(function() {
    // Initialize options first
    var options = {
        buildNavigation: false, 
        delay: 8000
    };

    // Only disable startStopped if the body has this class
    if ($('body').hasClass('partnerCharitiesDetail')) {
        options.startStopped = false;
    }

    // Show the #slideshow element and start the slideshow
    $('#slideshow').show();
    $('#slider1').anythingSlider(options);
});
