Do something if screen width is less than 960 px

Question

How can I make jQuery do something if my screen width is less than 960 pixels  The code below always fires the 2nd alert  regardless of my window size    if  screen width  lt  960        alert  Less than 960      else        alert  More than 960

You can also use a media query with javascript        const mq   window matchMedia    min-width  960px       if  mq matches           alert  window width  gt   960px      else        alert  window width  lt  960px

I recommend to not use jQuery for such thing and proceed with window innerWidth   if  window innerWidth  lt  960        doSomething

You might want to combine it with a resize event      window  resize function       if    window  width    lt  960         alert  Less than 960         else       alert  More than 960             For R J    var eventFired   0   if    window  width    lt  960        alert  Less than 960       else       alert  More than 960        eventFired   1       window  on  resize   function         if   eventFired            if    window  width    lt  960                alert  Less than 960 resize              else               alert  More than 960 resize                          I tried http   api jquery com off  with no success so I went with the eventFired flag

I would suggest  jQuery needed            windowSize    call this function to get windowSize any time     function windowSize       windowHeight   window innerHeight   window innerHeight     window  height      windowWidth   window innerWidth   window innerWidth     window  width          Init Function of init it wherever you like    windowSize        For example  get window size on window resize   window  resize function       windowSize      console log  width is     windowWidth   Height is     windowHeight     if  windowWidth  lt  768        console log  width is under 768px                Added in CodePen    http   codepen io moabi pen QNRqpY editors 0011  Then you can get easily window s width with the var   windowWidth  and Height with   windowHeight   otherwise  get a js library    http   wicky nillia ms enquire js
