let swipeStyle = $(".header,main>div").height(height); $(window).resize(function(){ height = $(window).height(); $(".header,main>div").height(height); width = $(window).width(); scroll(page,0); div.css("min-width",height/0.675+"px"); })解释代码

这段代码为网页中的元素设置高度和最小宽度，并且在窗口大小变化时动态地调整它们的大小。

首先，代码中定义了一个变量 `swipeStyle` 来存储对 `.header` 和 `main>div` 元素设置高度的操作。这里使用 `$()` 函数来选取对应的 DOM 元素，并使用 `.height()` 函数来设置它们的高度。

接下来，代码使用 `$(window).resize()` 函数来监听窗口大小变化事件。当窗口大小发生变化时，代码会获取新的窗口高度和宽度，并使用 `.height()` 函数来重新设置 `.header` 和 `main>div` 元素的高度。此外，代码还调用了 `scroll(page,0)` 来将滚动条滚动到页面顶部，以保证页面显示正常。

最后，代码使用 `.css()` 函数来设置 `div` 元素的最小宽度为 `(height/0.675)px`。这里使用 `div` 表示任意一个元素，因为代码中没有给出对应的元素选择器。

$(window).resize(function(){ height = $(window).height(); $(".header,main>div").height(height); width = $(window).width(); scroll(page,0); div.css("min-width",height/0.675+"px"); })解释代码

这段代码是 jQuery 代码，用于在窗口大小改变时自动调整页面元素的高度和宽度。

- `$(window).resize()` ：当窗口大小改变时，执行后面的函数。
- `height = $(window).height()` ：获取窗口的高度，并将其赋值给变量 height。
- `$(".header,main>div").height(height)` ：将类名为 header 的元素和 main 下的所有 div 元素的高度都设置为窗口的高度。
- `width = $(window).width()` ：获取窗口的宽度，并将其赋值给变量 width。
- `scroll(page,0)` ：滚动到页面的顶部。
- `div.css("min-width",height/0.675+"px")` ：将变量 div 的最小宽度设置为窗口高度除以 0.675 并加上单位 "px"，这里的 div 可能是一个 jQuery 对象或变量。

总的来说，这段代码的作用是让页面元素自适应窗口大小，保证页面显示效果的稳定和一致性。

上述代码实现了一个类似于Element UI中的Dialog组件的拖拽和缩放功能。在使用时，只需要将 `v-dialog-zoom-out` 指令绑定到Dialog组件的容器元素上，即可实现拖拽和缩放功能。
