用于多个div中文本截断的单个脚本

Question

This is continuation of my previous question .

Answer given by Joffrey worked fine But problem in that is, It loads the same content in all the divs which has the same class name.

This should work independently for each divs. If you check the demo attached, you can see all the divs are displaying the same content as first div even though each div has different content.

Here is the code used

var text = $('.truncate, .truncate_another').text();
    var shortText = $.trim(text).substring(0, 50).split(" ").slice(0, -1).join(" ") + "...";
    $('.truncate, .truncate_another').text(shortText);

    $('.truncate, .truncate_another').hover(function(){
        $(this).text(text);
        $('.truncate, .truncate_another').css('z-index', '10');
        $(this).css('z-index', '100');
    }, function(){
        $(this).text(shortText);
    });

Answer 1

Setting properties to outcome of $('.truncate, .truncate_another') will, as you've noticed, affect every matching item. Loop over the items to handle them separately:

$('.truncate, .truncate_another').each(function() {
  var text = $(this).text();
  var shortText = $.trim(text).substring(0, 50).split(" ").slice(0, -1).join(" ") + "...";
  $(this).text(shortText);

  $(this).hover(function(){
    $(this).text(text);
    $('.truncate, .truncate_another').css('z-index', '10');
    $(this).css('z-index', '100');
  }, function(){
    $(this).text(shortText);
  });
});
