Answer 1

Check the length of your jQuery "collection":

 if (jQuery('#bad-drifting li:has(em)').length > 0) { // There is at least one element

otherwise it will always be true, because what jQuery returns is always truthy.

Answer 2

That's because has returns a jQuery object and an object is a truthy value in JavaScript, you should use length property:

if (jQuery('#bad-drifting').has('em').length) {

Answer 3

You need to check for length because jQuery('#bad-drifting li:has(em)') returns a jQuery object which will be always truthy.

if (jQuery('#bad-drifting li:has(em)').length) { // .has('em')

Answer 4

if (jQuery('#bad-drifting').has('em')[0]) { // do Stuff

Answer 5

I ended up doing like this:

if (jQuery('#bad-drifting em').length > 0) {
    console.log('we have some errors');
}
