   var customQuery = oj.ResponsiveKnockoutUtils.createMediaQueryObservable(
                                        '(min-width: 400px)');

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

`queryString`	string	media query string, for example '(min-width: 400px)'

(static) createScreenRangeObservable

This function creates a computed observable, the value of which is one of the ResponsiveUtils.SCREEN_RANGE constants. For example when the width is in the range defined by the sass variable $mediumScreenRange then the observable returns oj.ResponsiveUtils.SCREEN_RANGE.MD, but if it's in the range defined by $largeScreenRange then it returns oj.ResponsiveUtils.SCREEN_RANGE.LG, etc.

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 }); <>

Returns:

a knockout observable the value of which is one of the screen range constants, for example oj.ResponsiveUtils.SCREEN_RANGE.MD
