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?


当前回答

但是当我们谈论响应屏幕时,如果出于某种原因我们想使用jQuery处理它,

window.innerWidth, window.innerHeight

给出正确的测量值。即使它删除了滚动条的额外空间,我们也不必担心调整空间:)

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)

有时您需要在调整窗口大小和内部内容时查看宽度/高度的变化。

为此,我编写了一个小脚本,它添加了一个日志框,动态地监视所有的大小调整和几乎立即的更新。

它添加了一个具有固定位置和高z索引的有效HTML,但足够小,因此您可以:

在实际现场使用用于测试移动/响应意见

已在:Chrome 40、IE11上测试,但也很有可能在其他/较旧的浏览器上工作…:)

  function gebID(id){ return document.getElementById(id); }
  function gebTN(tagName, parentEl){ 
     if( typeof parentEl == "undefined" ) var parentEl = document;
     return parentEl.getElementsByTagName(tagName);
  }
  function setStyleToTags(parentEl, tagName, styleString){
    var tags = gebTN(tagName, parentEl);
    for( var i = 0; i<tags.length; i++ ) tags[i].setAttribute('style', styleString);
  }
  function testSizes(){
    gebID( 'screen.Width' ).innerHTML = screen.width;
    gebID( 'screen.Height' ).innerHTML = screen.height;

    gebID( 'window.Width' ).innerHTML = window.innerWidth;
    gebID( 'window.Height' ).innerHTML = window.innerHeight;

    gebID( 'documentElement.Width' ).innerHTML = document.documentElement.clientWidth;
    gebID( 'documentElement.Height' ).innerHTML = document.documentElement.clientHeight;

    gebID( 'body.Width' ).innerHTML = gebTN("body")[0].clientWidth;
    gebID( 'body.Height' ).innerHTML = gebTN("body")[0].clientHeight;  
  }

  var table = document.createElement('table');
  table.innerHTML = 
       "<tr><th>SOURCE</th><th>WIDTH</th><th>x</th><th>HEIGHT</th></tr>"
      +"<tr><td>screen</td><td id='screen.Width' /><td>x</td><td id='screen.Height' /></tr>"
      +"<tr><td>window</td><td id='window.Width' /><td>x</td><td id='window.Height' /></tr>"
      +"<tr><td>document<br>.documentElement</td><td id='documentElement.Width' /><td>x</td><td id='documentElement.Height' /></tr>"
      +"<tr><td>document.body</td><td id='body.Width' /><td>x</td><td id='body.Height' /></tr>"
  ;

  gebTN("body")[0].appendChild( table );

  table.setAttribute(
     'style',
     "border: 2px solid black !important; position: fixed !important;"
     +"left: 50% !important; top: 0px !important; padding:10px !important;"
     +"width: 150px !important; font-size:18px; !important"
     +"white-space: pre !important; font-family: monospace !important;"
     +"z-index: 9999 !important;background: white !important;"
  );
  setStyleToTags(table, "td", "color: black !important; border: none !important; padding: 5px !important; text-align:center !important;");
  setStyleToTags(table, "th", "color: black !important; border: none !important; padding: 5px !important; text-align:center !important;");

  table.style.setProperty( 'margin-left', '-'+( table.clientWidth / 2 )+'px' );

  setInterval( testSizes, 200 );

编辑:现在样式只应用于记录器表元素,而不是应用于所有表-这也是一个jQuery免费解决方案:)

这是我的解决方案!

//内部宽度常量screen_viewport_inner=()=>{设w=窗口,i=“内部”;if(!(窗口中的`innerWidth`)){i=“客户端”;w=document.documentElement | | document.body;}返回{width:w[`${i}宽度`],高度:w[`${i}高度`]}};//外侧宽度常量screen_viewport_outer=()=>{设w=窗口,o=“外部”;if(!(窗口中的`outerWidth`)){o=“客户端”;w=document.documentElement | | document.body;}返回{width:w[`${o}宽度`],高度:w[`${o}高度`]}};//样式常量console_color=`颜色:rgba(0255,0,0.7);字体大小:1.5rem;边框:1px纯红色;`;//测试常量测试=()=>{让i_obj=screen_viewport_inner();console.log(`%c screen_viewport_inner=\n`,console_color,JSON.stringfy(i_obj,null,4));让o_obj=screen_viewport_out();console.log(`%c screen_viewport_outer=\n`,console_color,JSON.stringify(o_obj,null,4));};//生命(() => {测试();})();

这有您需要知道的一切:获取视口/窗口大小

但简而言之:

var win = window,
    doc = document,
    docElem = doc.documentElement,
    body = doc.getElementsByTagName('body')[0],
    x = win.innerWidth || docElem.clientWidth || body.clientWidth,
    y = win.innerHeight|| docElem.clientHeight|| body.clientHeight;
alert(x + ' × ' + y);

不停摆弄

请停止编辑此答案。它已经被不同的人编辑了22次,以符合他们的代码格式偏好。也有人指出,如果你只想瞄准现代浏览器,这是不需要的——如果是的话,你只需要以下内容:

const width  = window.innerWidth || document.documentElement.clientWidth || 
document.body.clientWidth;
const height = window.innerHeight|| document.documentElement.clientHeight|| 
document.body.clientHeight;

console.log(width, height);
