调整浏览器窗口大小的JavaScript功能

Question

I have been writting HTML and CSS for a while but am new to the javascript domain. I am using the below code to control the attributes of a jQuery slider. The code works fine, but what I need to do is change some of the elements within it as the browser screen resizes (or loaded on mobile device) to enable the functionality to work correctly on smaller screens.

 $(document).ready(
        function() {
            $(".container").wtListRotator({
                screen_width:534,
                screen_height:300,
                item_width:210,
                item_height:75,
                item_display:4,
                list_align:"left",
                scroll_type:"mouse_move",
                auto_start:true,
                delay:5000,
                transition:"v.slide",
                transition_speed:800,
                easing:"",
                auto_center:true,
                display_playbutton:false,
                display_number:false,
                display_timer: false,
                display_arrow:true,
                display_thumbs:true,
                display_scrollbar:true,
                mouseover_select:false,
                pause_mouseover: true,
                cpanel_mouseover:false,                 
                text_mouseover:false,
                text_effect:"fade",
                text_sync:true,
                cpanel_align:"TR",
                timer_align:"bottom",
                move_one:false,
                auto_adjust:true,
                shuffle:false,
                play_once:false,
                mousewheel_scroll:true,                 
                block_size:75,
                vert_size:50,
                horz_size:50,
                block_delay:35,
                vstripe_delay:90,
                hstripe_delay:180                   
            });
        }
    );

I have already implemented media queries on the elements in the CSS so they resize and also across the rest of my site, however I am struggling to change the attributes below when the screen size/re-size event occurs and define this in the above javascript.

screen_width:534,
                screen_height:300,
                item_width:210,
                item_height:75,
                item_display:4,   

Thanks

Answer 1

two things that might help you:

1) you can always get the current usable width/height of the browser window using window.innerWidth and window.innerHeight .

2) you can "register" a function to be called whenever the size of the window changes. Examples:

window.addEventListener("resize",nameOfFunction);

window.onresize = function() { //do stuff };

I'm happy to help if you have further questions...
