vanilla_trim_text_multiple_els.js

// Trim to 15 words
document.addEventListener("DOMContentLoaded", function() {
	
	var myElements = document.getElementsByClassName('elemsToTrim');

	// Real improved for loop: https://stackoverflow.com/questions/31352367/how-can-i-make-sublime-texts-improved-native-for-loop-increment-like-a-normal#answer-31352368
	for (var i = 0, l = myElements.length; i < l; ++i) {
		delay(i);
	}

	function delay(i) {
		// Sometimes could be useful to make it async in order to avoid blocking the JS event loop
		setTimeout(function() {
			var myEl = myElements[i].innerText.split(" ").splice(0, 15).join(" ");
			myElements[i].innerText = myEl.slice(-1) == '.' ? myEl : myEl + ' ...';
		}, 0);		
	}
