关于如何不使用jQuery获得div的高度有什么想法吗?
我在Stack Overflow中搜索这个问题，似乎每个答案都指向jQuery的.height()。
我尝试了myDiv.style。但是它没有返回任何东西，即使我的div在CSS中设置了它的宽度和高度。

最好的办法是——
var myDiv = document.getElementById('myDiv'); var myDivWidth = myDiv.clientWidth || myDiv.offsetWidth || (myDiv.getBoundingClientRect()).width; var myDivHeight= myDiv.clientHeight || myDiv.offsetHeight || (myDiv.getBoundingClientRect()).height; console.log("Width: "+ myDivWidth + "px"); console.log("Height: "+ myDivHeight + "px"); <div style="padding: 50px; margin: 8px auto; outline: 1px solid green;"> <div id="myDiv" style="width: 100%; height: 256px; padding: 50px; margin: 4px; background: #000000; color: #ffffff; outline: 1px solid red;"> This is "#myDiv" <br> Width: 100% <br> Height: 256px </div> </div>

HTMLElement。返回已定义的元素样式 clientHeight -高度+填充 offsetHeight -高度+填充+边框 scrollHeight -返回高度+填充 getBoundingClientRect() -返回左，上，右，下，x, y， 宽度和高度属性 getComputedStyle() -返回元素的所有CSS属性
// returns defined Style of element const styleHeight = document.getElementById('myDiv').style.height; console.log('style Height : ', styleHeight); // height + padding const clientHeight = document.getElementById('myDiv').clientHeight; console.log('client Height : ', clientHeight); // height + padding + borders const offsetHeight = document.getElementById('myDiv').offsetHeight; console.log('offset Height : ', offsetHeight); // height + padding const scrollHeight = document.getElementById('myDiv').scrollHeight; console.log('scroll Height : ', scrollHeight); // return left, top, right, bottom, x, y, width, and height properties const getBoundingClientRectHeight = document.getElementById('myDiv').getBoundingClientRect().height; console.log('get Bounding Client Rect Height : ', getBoundingClientRectHeight); // returns all CSS properties of an element const styleElementHeight = getComputedStyle(document.getElementById("myDiv")).height; console.log('style Element Height : ', styleElementHeight); <div id="myDiv" style="margin:10px;padding:20px;height:200px;"> <input type="Text"> <input type="button" value="submit"> </div>
try
myDiv.offsetHeight
console.log(“高度:”,myDiv。offsetHeight); #myDiv{宽度:100px;身高:666 px;背景:红} < div id = " myDiv " > < / div >
var clientHeight = document.getElementById('myDiv').clientHeight;
or
var offsetHeight = document.getElementById('myDiv').offsetHeight;
clientHeight包含填充。
offsetHeight包括填充，滚动条和边界。

除了el。clientHeight和el。当你需要元素内部内容的高度时(不管元素本身设置的高度)，你可以使用el.scrollHeight。更多信息
如果你想将元素高度或max-height设置为内部动态内容的精确高度，这可能很有用。例如:
var el = document.getElementById('myDiv')
el.style.maxHeight = el.scrollHeight+'px'
