K2: Select Listview rows with checkboxes

k2-listview-checkboxes.js

//You need to do the following for the code to work:
//1. Add Literal datalabel to the list view and call it 'dlblScript'.
//2. Add a new column into the list view, add literal datalabel there and add a piece of the following html inside:
<input type="checkbox" class="custom-box"/>
//3. Add the following js into the dlblScript:
<script>
var contentTable = $("span[name='dlblScript']").closest('.grid').find('.grid-content-table')[0];
var observer = new MutationObserver(function(mutations){
	$(contentTable).find('.custom-box').each(function(i, val){
		if ($(this).prop('checked')){
			$(this).closest('tr').addClass('highlighted selected');
		} else{
			$(this).closest('tr').removeClass('highlighted selected');
		}
		
	});
});
var config = {attributes:true, subtree:true, characterData: true};
observer.observe(contentTable, config);
</script>
