Question

I’m curious to know if it’s possible to switch between Javascript insertRule and addRule methods in Javascript without using browser sniffing/conditional comments to assign addRule to IE.

In CSS, I can use properties that aren’t supported on specific devices (IE ::pseudo-selector for example) to write rules for specific browsers. Is there a similar trick in Javascript?

Thanks for some insights!

Answer 1

if(sheet.addRule) { 
    sheet.addRule(...);
}
else
{
    sheet.insertRule(...);
}
