Introduction to jQuery offsetWidth

Web development, programming languages, Software testing & others

Syntax:

HTML_element.offsetWidth

In this article, the syntax is as shown in the above in which this jQuery property is applied on any matched or selected HTML element to find the width of that element, and it also has options of getting details of other properties like padding, border, scrolling but not the margin property. In most cases, this property is used along with offsetHeight property, and this property is said to be viewable property because this provides the width of the element which is viewable to it and not the elements that are not viewable, and hence this property is said to be read-only property.

In jQuery, this property returns only the width of any viewable element in numbers format with the unit as pixels and includes padding, border, and scrolling such as scrollbar.

How to Set the offsetWidth in jQuery?

In jQuery, the working of the offsetWidth property is very simple. This property is mostly used along with offsetHeight for setting the height and width of any matched or selected HTML elements.

The offsetWidth is one of the built-in property provided by jQuery, which is used for displaying the width of the element where only the viewable element’s width is displayed when this offsetWidth property is applied to any element, and this is done by selecting the element first for which we need to display the width and is followed by dot operator with offsetWidth property.

Therefore, when we apply this property, it will return the width of the element viewed by this property and give the number in pixels for displaying the width.

Examples of jQuery offsetWidth

Given below are the examples of jQuery offsetWidth:

Example #1

Code:

#divid { height: 250px; width: 400px; padding: 10px; margin: 15px border: 5px solid yellow; background-color: orange; } function func() { var elmnt = document.getElementById(“divid”); txt += “Width including padding and border: ” + elmnt.offsetWidth + “px”; document.getElementById(“off”).innerHTML = txt; }

Output:

In the above code, we can see we are using this offsetWidth on the “div” element. Firstly, we have created a div element with its different properties such as its normal height, width, padding, border, color, etc. and this “div” element is given an id named “divid”, for which we have defined the properties within the style tag in the head tag.

Example #2

Another example where we also are using scrollbar along with offsetWidth or offsetHeight.

Code:

#DIV1 { height: 150px; width: 300px; padding: 10px; margin: 15px; border: 5px solid yellow; overflow: auto; } #DIV2 { height: 150px; width: 300px; padding: 10px; margin: 15px; border: 5px solid blue; background-color: lightblue; } #info { height: 800px; width: 2000px; } function func() { var elmnt = document.getElementById(“DIV1”); var txt = “”; txt += “Width including padding, border and scrollbar: ” + elmnt.offsetWidth + “px”; document.getElementById(“info”).innerHTML = txt; var elmnt2 = document.getElementById(“DIV2”); var txt2 = “”; txt2 += “Width including padding and border: ” + elmnt2.offsetWidth + “px”; document.getElementById(“info2”).innerHTML = txt2; }

Conclusion

In this article, we conclude that the offsetWidth property in jQuery is the built-in property for displaying the viewable width for any matched element and is mostly used along with offsetHeight. In jQuery, there are other properties like clientHeight and clientWidth, which is similar to offsetHeight and offsetWidth.
