Padding or margin value in pixels as integer using jQuery

Question

jQuery has height() en width() functions that returns the height or width in pixels as integer...

How can I get a padding or margin value of an element in p

Answer 1

Not to necro but I made this which can determine pixels based on a variety of values:

$.fn.extend({
  pixels: function (property, base) {
    var value = $(this).css(property);
    var original = value;
    var outer = property.indexOf('left') != -1 || property.indexOf('right') != -1 
      ? $(this).parent().outerWidth()
      : $(this).parent().outerHeight();

    // EM Conversion Factor
    base = base || 16;

    if (value == 'auto' || value == 'inherit') 
        return outer || 0;

    value = value.replace('rem', '');
    value = value.replace('em', '');

    if (value !== original) {
       value = parseFloat(value);
       return value ? base * value : 0;
    }

    value = value.replace('pt', '');

    if (value !== original) {
       value = parseFloat(value);
       return value ? value * 1.333333 : 0; // 1pt = 1.333px
    }

    value = value.replace('%', '');

    if (value !== original) {
      value = parseFloat(value);
      return value ? (outer * value / 100) : 0;
    }

    value = value.replace('px', '');
    return parseFloat(value) || 0;
  }
});

This way, we take into account for sizing, and auto / inherit.
