Can someone help me figure out how to extract the border-width using ComputerStyle with the following command?
window.getComputedStyle(box).getPropertyValue("border")
Currently, it is returning:
"0.994318px solid rgb(255, 0, 0)"
Is there a way to change the argument "border" so that in the above case, it would output just
0.994318px
Just like the question asking why .getPropertyValue() doesn't return a value for the "borderRadius" property
You need to specify the specific CSS property you want, such as 'border-width'
Update: As mentioned by @HereticMonkey (which I missed in the linked post), Firefox requires very specific property targeting. For example, when trying to get border-width, you should target the exact border, like border-bottom-width.
To retrieve the 'border-top-width' property value from a specific class, you can follow these steps:
<style>.mystyle{border:8px solid grey;padding:10px;}</style>
<div id="xyz" class="mystyle">just testing</div>
<script>
var myDiv = document.getElementById('xyz');
var borderTopWidth = parseInt(getComputedStyle(myDiv).getPropertyValue("border-top-width").replace('px',''));
console.log('The border-top-width value is:'+borderTopWidth);// -> 8
</script>
