如何获取windowWidth、windowHeight、pageWidth、pageHeight、screenWidth、screenHeight、pageX、pageY、screenX、screenY,这些都可以在所有主要浏览器中使用?

使用“控制台”或单击“检查”后,检查任何网站当前加载页面的高度和宽度。

步骤1:单击鼠标右键,单击“检查”,然后单击“控制台”

步骤2:确保您的浏览器屏幕不应处于“最大化”模式。如果浏览器屏幕处于“最大化”模式,您需要首先单击最大化按钮(位于右上角或左上角),然后取消最大化。

步骤3:现在,在大于号('>')后面写以下内容,即。

       > window.innerWidth
            output : your present window width in px (say 749)

       > window.innerHeight
            output : your present window height in px (say 359)

与屏幕尺寸相关的完整指南

JavaScript

高度:

document.body.clientHeight  // Inner height of the HTML document body, including padding 
                            // but not the horizontal scrollbar height, border, or margin

screen.height               // Device screen height (i.e. all physically visible stuff)
screen.availHeight          // Device screen height minus the operating system taskbar (if present)
window.innerHeight          // The current document's viewport height, minus taskbars, etc.
window.outerHeight          // Height the current window visibly takes up on screen 
                            // (including taskbars, menus, etc.)

注意:当窗口最大化时,这将等于screen.availHeight

宽度:

document.body.clientWidth   // Full width of the HTML page as coded, minus the vertical scroll bar
screen.width                // Device screen width (i.e. all physically visible stuff)
screen.availWidth           // Device screen width, minus the operating system taskbar (if present)
window.innerWidth           // The browser viewport width (including vertical scroll bar, includes padding but not border or margin)
window.outerWidth           // The outer window width (including vertical scroll bar,
                            // toolbars, etc., includes padding and border but not margin)

滑动分页

高度:

$(document).height()    // Full height of the HTML page, including content you have to 
                        // scroll to see

$(window).height()      // The current document's viewport height, minus taskbars, etc.
$(window).innerHeight() // The current document's viewport height, minus taskbars, etc.
$(window).outerHeight() // The current document's viewport height, minus taskbars, etc.                         

宽度:

$(document).width()     // The browser viewport width, minus the vertical scroll bar
$(window).width()       // The browser viewport width (minus the vertical scroll bar)
$(window).innerWidth()  // The browser viewport width (minus the vertical scroll bar)
$(window).outerWidth()  // The browser viewport width (minus the vertical scroll bar)

这里是一个纯JavaScript的跨浏览器解决方案(源代码):

var width = window.innerWidth
|| document.documentElement.clientWidth
|| document.body.clientWidth;

var height = window.innerHeight
|| document.documentElement.clientHeight
|| document.body.clientHeight;

您可以使用jQuery获取窗口或文档的大小:

// Size of browser viewport.
$(window).height();
$(window).width();

// Size of HTML document (same as pageHeight/pageWidth in screenshot).
$(document).height();
$(document).width();

对于屏幕大小,可以使用屏幕对象:

window.screen.height;
window.screen.width;

我开发了一个库来了解桌面和移动浏览器的真实视口大小,因为不同设备的视口大小不一致,无法依赖该帖子的所有答案(根据我对此所做的所有研究):https://github.com/pyrsmk/W

在某些情况下,与响应布局相关的$(document).height()可能会返回错误的数据,仅显示视图端口高度。例如,当某个div#wrapper的高度为100%时,该#wrappers可以被其内部的某个块拉伸。但它的高度仍将与视口高度相同。在这种情况下,您可以使用

$('#wrapper').get(0).scrollHeight

表示包装器的实际大小。
