Class Detection

We include our ‘core’ library, in the header

    <script src="../Include/Core.js" type="text/javascript"></script>
          

The function ssHasClass() works out whether an element has a class or not.

It takes in an element and a class as parameters and returns true or false.

Here we use it as we loop through a set of elements, to check whether each one has the class ‘alert’.

    function prepareAlerts()
    {
      var anchors = document.getElementsByTagName("a");
      for (var aCount=0; aCount != anchors.length; aCount++)
      {
        if (ssHasClass(anchors[aCount],"alert"))
        {
          ssAddEvent(anchors[aCount], "click", showAlert, false);
        }
      }
    }
          

An easier way to deal with a set of elements is provided by our other class detection function ssGetElementsByClass().
