How to get the div height using JavaScript ?
In this article, we will see How to get the div height using Javascript. We can do this by following ways:
- Using the offsetHeight property.
- Using the clientHeight property.
- Using getBoundingClientRect() Method.
Method 1: Using the offsetHeight property: The offsetHeight property of an element is a read-only property and is used to return the height of an element in pixels. It includes any borders or padding of the element. This property can be used to find the height of the <div> element.
Syntax:
divElement.offsetHeight
Example: In this example, we will use the offsetHeight property.
html
< style > .box { height: 100px; width: 100px; background-color: green; display: inline-block; } </ style > < h1 style = "color: green" > GeeksforGeeks </ h1 > < b > Get the height of < div > element using JavaScript </ div > </ b > < p > Click on the button to get the height of element </ p > < div class = "box" ></ div > < p > Height of the div: < span class = "output" ></ span > </ p > < button onclick = "getHeight()" > Get Height </ button > < script type = "text/javascript" > function getHeight() { divElement = document.querySelector(".box"); elemHeight = divElement.offsetHeight; document.querySelector(".output").textContent = elemHeight + "px"; } </ script > |
Output:
Method 2: Using clientHeight property: The clientHeight property of an element is a read-only property and is used to return the height of an element in pixels. It includes only the padding applied to the element and excludes the borders, margins, or horizontal scrollbars. This property can be used to find the height of the div element.
Syntax:
divElement.clientHeight
Example: In this example, we will use the clientHeight property.
html
<!-- HTML elements to iterate --> < style > .box { height: 100px; width: 100px; background-color: green; display: inline-block; } </ style > < h1 style = "color: green" > GeeksforGeeks </ h1 > < b > Get the height of < div > element using JavaScript </ div > </ b > < p > Click on the button to get the height of < div > element </ div > </ p > < div class = "box" ></ div > < p > Height of the div: < span class = "output" ></ span > </ p > < button onclick = "getHeight()" > Get Height </ button > < script type = "text/javascript" > function getHeight() { divElement = document.querySelector(".box"); elemHeight = divElement.clientHeight; document.querySelector(".output").textContent = elemHeight + "px"; } </ script > |
Output:
Method 3: Using getBoundingClientRect() Method: The getBoundingClientRect() method is used to return a DOMRect object which contains 8 properties related to the dimensions of the bounding rectangle. One of these properties of the DOMRect object is the height property. It returns the height of the DOMRect object. This property can be used to find the height of the div element.
Syntax:
elemRect = divElement.getBoundingClientRect(); elemHeight = elemRect.height;
Example: In this example, we will see the use of getBoundingClientRect() Method
html
< style > .box { height: 100px; width: 100px; background-color: green; display:inline-block; } </ style > < h1 style = "color: green" > GeeksforGeeks </ h1 > < b > Get the height of < div > element using JavaScript </ div > </ b > < p > Click on the button to get the height of < div > element </ div > </ p > < div class = "box" ></ div > < p > Height of the div: < span class = "output" ></ span > </ p > < button onclick = "getHeight()" > Get Height </ button > < script type = "text/javascript" > function getHeight() { divElement = document.querySelector(".box"); elemRect = divElement.getBoundingClientRect(); elemHeight = elemRect.height; document.querySelector(".output").textContent = elemHeight + "px"; } </ script > |
