Problem Description
In Internet Explorer, when calculating the width of an element using JavaScript, errors often occur. For example, when a container element contains some child elements, we want to determine the total width of all child elements in the container by calculating the scrollWidth of the container element, but in IE, we may get an incorrect result.
Cause of the problem
IE browser is calculating When calculating scrollWidth, the container element’s padding and border width are also taken into account. This can cause unexpected results when using the scrollWidth property.
Solution
To resolve this issue, we can use CSS to fix the scrollWidth calculation error. Here are two common solutions:
Method 1: Overflow and Padding
One solution is to set the overflow property of the container element to scroll and then set the padding to 0. This way, the container element’s scrollWidth will accurately calculate the total width of all child elements, without including padding and border width.
.container {
overflow: scroll;
padding: 0;
}
Method 2: box-sizing
Another solution is to use the box-sizing property. By setting the container element’s box-sizing to border-box, the container element’s scrollWidth will accurately calculate the total width of all child elements, including padding and border width.
.container {
box-sizing: border-box;
}
Both methods effectively resolve the scrollWidth issue in IE; choose the one that works best for your situation.
Example
To better illustrate this problem and its solution, here’s an example. Suppose we have a container element that contains some child elements, and we want to calculate the total width of the container element.
<!DOCTYPE html>
<html>
<head>
<style>
.container {
border: 1px solid black;
overflow: scroll;
padding: 0;
width: 200px;
}
.child {
width: 100px;
height: 100px;
background-color: red;
display: inline-block;
}
</style>
</head>
<body>
<div class="container">
<div class="child"></div>
<div class="child"></div>
<div class="child"></div>
</div>
<script>
const container = document.querySelector('.container');
console.log(container.scrollWidth); // Outputs 300
</script>
</body>
</html>
In the example above, we set up a container element and placed three child elements within it. The container element has a width of 200px, and each child element has a width of 100px. We used JavaScript to output the scrollWidth of the container element, which should be 300. However, in Internet Explorer, without a workaround, we’ll likely get an incorrect result. Using one of the two workarounds above will yield the correct result.
Summary
In Internet Explorer, the scrollWidth property has some issues with calculation, particularly when it comes to padding and border width. To address this, we can use CSS to fix the scrollWidth calculation errors. By setting the overflow property to scroll and setting padding to 0, or using the box-sizing property, we can accurately calculate the scrollWidth of the container element, unaffected by padding and border width. Choose the appropriate solution based on your situation to ensure correct results in Internet Explorer.
