jQuery的each内部的break，continue

// break, continue在each等迭代器里都不可用
// return false = break
// return true = continue
function isClickedSelectedBodyType(self) {
    var selected = null;
    $('.body_type_select_button').each(function () {
      var title = this.getElementsByClassName('img-title')[0];
      selected = this;
      if ($(title).css('color') === selectedBodyTypeFontColor) {
        if (selected === self) {
          return false; // break
        }
      }
    });
    return self === selected;
  }
