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;

  }
