jquery – ToolTips for ONLY a long sentence

Posted by: admin February 22, 2020 Leave a comment


I have a UL LI dropdown menu, each LI element has a different length. If I pick a LI with long sentence, it will show only a part of this sentence and … at the end.

Goal: If a short sentence is picked, it won’t show a tooltip when hovering it. If I pick a long sentence, then I hover it, a tooltip will show its entire name.

Problem: If I pick a long sentence, I hover it, a tooltip will show its entire name, THEN I pick a short sentence, it shouldn’t shows a tooltip, but it hover it, the tooltip shows previous long sentence with I just picked.

Please help.

$(document).on("click", '.list-unstyled li', function() {
  var textString = $(this).html();

  console.log("This : " + textString);
  console.log('length: ' + textLength);
  $(document).on('mouseenter', '.list-unstyled', function() {
    if (textLength > 30) {
    } else {}

  $(document).on('mouseleave', '.list-unstyled', function() {
