Example:


       // create an observable which returns the current screen range
       self.screenRange = oj.ResponsiveKnockoutUtils.createScreenRangeObservable();

       self.label2 = ko.computed(function() {
         var range = self.screenRange();

         if ( oj.ResponsiveUtils.compare(
                      range, oj.ResponsiveUtils.SCREEN_RANGE.MD) <= 0) { code for when screen is in small or medium range } else if (range="=" oj.responsiveutils.screen_range.xl) xl }); <>

Parameters:

Name	Type	Description
`size1`	ResponsiveUtils.ScreenRange	one of the screen size constants, for example oj.ResponsiveUtils.SCREEN_RANGE.MD
`size2`	ResponsiveUtils.ScreenRange	one of the screen size constants, for example oj.ResponsiveUtils.SCREEN_RANGE.LG

Returns:

Example:



    var lgQuery = oj.ResponsiveUtils.getFrameworkQuery(
                            oj.ResponsiveUtils.FRAMEWORK_QUERY_KEY.LG_UP);

    self.large = oj.ResponsiveKnockoutUtils.createMediaQueryObservable(lgQuery);

Parameters:

Name	Type	Description
`frameworkQueryKey`	ResponsiveUtils.FrameworkQueryKey	one of the FRAMEWORK_QUERY_KEY constants, for example oj.ResponsiveUtils.FRAMEWORK_QUERY_KEY.MD_UP

Returns:

the media query to use for the framework query key passed in
