Cómo dejar de código JS de envolver los espacios en blanco en un lapso?

Gregory Schultz:

He encontrado el código JS de " Detectar líneas ajustadas navegador utilizando Javascript " pero va a envolver los espacios en blanco en un palmo. Estoy usando este código en un sitio de WordPress y no puedo reciprocar el problema en otro sitio. Traté de desinfectar el código, pero eso no funcionó así.

¿Hay una manera de comprobar si un lapso está en blanco y quitar el lapso?

$(".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">');
    }

  };
});

vuryss:

Puede comprobar si el contenido que está siendo envuelto no está vacío.

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

He aquí el fragmento editado:

$(".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">');
    }

  };
});
