Как остановить код JS от переноса пробелов в промежуток?

Question

Я обнаружил код JS из " Обнаружение строк, обернутых браузером, через javascript", но он будет переносить пробелы в промежуток. Я использую этот код на сайте WordPress, и я не могу ответить на проблему в другом месте. Я пытался очистить код, но это тоже не сработало.

Есть ли способ проверить, является ли промежуток пустым, и удалить его?

$(".emails .multi-items .content").each(function() {
  var $cont = $(this);

  var text_arr = $cont.text().split(' ');

  for (i = 0; i < text_arr.length; i++) {
    text_arr[i] = '<span>' + text_arr[i] + ' </span>';
  }

  $cont.html(text_arr.join(''));

  $wordSpans = $cont.find('span');

  var lineArray = [],
    lineIndex = 0,
    lineStart = true,
    lineEnd = false

  $wordSpans.each(function(idx) {
    var pos = $(this).position();
    var top = pos.top;

    if (lineStart) {
      lineArray[lineIndex] = [idx];
      lineStart = false;

    } else {
      var $next = $(this).next();

      if ($next.length) {
        if ($next.position().top > top) {
          lineArray[lineIndex].push(idx);
          lineIndex++;
          lineStart = true
        }
      } else {
        lineArray[lineIndex].push(idx);
      }
    }

  });


  //console.log( lineArray)
  for (i = 0; i < lineArray.length; i++) {
    var start = lineArray[i][0],
      end = lineArray[i][1] + 1;

    /* no end value pushed to array if only one word last line*/
    if (!end) {
      $wordSpans.eq(start).wrap('<span class="line_wrap">')
    } else {
      $wordSpans.slice(start, end).wrapAll('<span class="line_wrap">');
    }

  };
});

Вы можете проверить, не является ли содержимое, которое оборачивается, пустым.

for (i = 0; i < text_arr.length; i++) {
    if (text_arr[i].trim().length > 0) {
        text_arr[i] = '<span>' + text_arr[i] + ' </span>';
    }
}

Вот отредактированный фрагмент:

$(".emails .multi-items .content").each(function() {
  var $cont = $(this);

  var text_arr = $cont.text().split(' ');

  for (i = 0; i < text_arr.length; i++) {
      if (text_arr[i].trim().length > 0) {
          text_arr[i] = '<span>' + text_arr[i] + ' </span>';
      }
  }

  $cont.html(text_arr.join(''));

  $wordSpans = $cont.find('span');

  var lineArray = [],
    lineIndex = 0,
    lineStart = true,
    lineEnd = false

  $wordSpans.each(function(idx) {
    var pos = $(this).position();
    var top = pos.top;

    if (lineStart) {
      lineArray[lineIndex] = [idx];
      lineStart = false;

    } else {
      var $next = $(this).next();

      if ($next.length) {
        if ($next.position().top > top) {
          lineArray[lineIndex].push(idx);
          lineIndex++;
          lineStart = true
        }
      } else {
        lineArray[lineIndex].push(idx);
      }
    }

  });


  //console.log( lineArray)
  for (i = 0; i < lineArray.length; i++) {
    var start = lineArray[i][0],
      end = lineArray[i][1] + 1;

    /* no end value pushed to array if only one word last line*/
    if (!end) {
      $wordSpans.eq(start).wrap('<span class="line_wrap">')
    } else {
      $wordSpans.slice(start, end).wrapAll('<span class="line_wrap">');
    }

  };
});
