jquery - jQuery 中的放大/缩小事件

Question

我只是想要一个功能，在放大窗口上显示警报，比如“你放大了”，在缩小窗口上显示警报，比如“你缩小了”，我搜索了这个功能很多时间，但每次搜索我都会得到就像“放大窗口事件”一样，这不是我想要的。

srceen.width is fixed value but where as window.innerWidth value will change as per the zoom effect. please try the below code:

 $(window).resize(function() {
       if(screen.width == window.innerWidth){
           alert("you are on normal page with 100% zoom");
       } else if(screen.width > window.innerWidth){
           alert("you have zoomed in the page i.e more than 100%");
       } else {
           alert("you have zoomed out i.e less than 100%")
       }
    });
