禁止横竖屏切换、强制横竖屏

禁止横竖屏切换、强制横竖屏:


js判断屏幕横竖屏:
function orient() {
        //alert('gete');
        if (window.orientation == 0 || window.orientation == 180) {
            $("body").attr("class", "portrait");
            orientation = 'portrait';
            return false;
        }
        else if (window.orientation == 90 || window.orientation == -90) {
            $("body").attr("class", "landscape");
            orientation = 'landscape';
   
            return false;
        }
    }
   
   
    $(function(){
        orient();
    });
   
   
    $(window).bind( 'orientationchange', function(e){
        orient();
    });
