将添加/移除类隔离到单击项

Question

目前，我有一个手风琴菜单，每次单击.responsive-accordion-head时，我都告诉它切换类如下：

$('.responsive-accordion-head').click(function () {

    if ( $( '.responsive-accordion-head i' ).hasClass( "plus-2" ) ) {

        $('.responsive-accordion-head i').removeClass("plus-2");
        $('.responsive-accordion-head i').addClass("minus-2");

    } else {
        $('.responsive-accordion-head i').removeClass("minus-2");
        $('.responsive-accordion-head i').addClass("plus-2");
    }

});

我遇到的问题是，上面的代码更改了所有.responsive-accordion-head元素的类。我需要它是特定于单击的项目只。我该怎么做？

Answer 1

所有这些可能都可以简化为：

$('.responsive-accordion-head').click(function () {
    $(this).find('i').toggleClass('plus-2 minus-2');
});
