jQuery - 如何知道窗口是在宽度/高度还是两者都调整大小？ [英] jQuery - How to know if window is resizing in width/height or both?

问题描述

我使用jQuery的函数 .resize（）来调整窗口大小有一点问题。我想知道哪个尺寸越来越大 - 宽度或高度。我需要这个，因为如果我只提出两个条件 - 如果宽度比div大50px并且如果高度比div大50px，那么

I have a little problem with window resizing using jQuery's function .resize(). I would like to know which dimension is getting bigger/smaller - width or height. I need this because if I just put two conditions - if width is for 50px bigger than div and if height is for 50px bigger than div,

// (pseudocode)
if width = div.width + 50px
   width = something
if height = div.height + 50px
   height = something

然后只处理一个条件，我只能调整宽度或高度。

then is working on just one condition and I can resize only width or height.

我怎么知道哪个尺寸正在改变或者两者都是？

How could I know which dimension is changing in size or if both are?

推荐答案

通过保存最后一个窗口变量中的大小值。

By saving last window size values in variables.

var h = $(window).height(), w = $(window).width();
$(window).resize(function(){

    var nh = $(window).height(), nw = $(window).width();
     // compare the corresponding variables.
    h = nh; w = nw; // update h and w;
});
