Utility classes can help you perform common tasks more easily.
Explanation
hasClass(elm, classN): Checks if an element has a specific class.getCssProperty(elm, prop): Gets the computed value of a CSS property for an element.
Usage
To use these utility classes, you can call the static methods on the SuperTools class:
class SuperTools {
static hasClass(elm, classN) {
return new RegExp('(\\s|^)' + classN + '(\\s|$)').test(elm.classN);
}
static getCssProperty(elm, prop) {
return window.getComputedStyle(elm, null).getPropertyValue(prop);
}
}
SuperTools.hasClass(elm, 'class-name');
