Question

我正在尝试编写一个脚本，当我单击文本时，我会使箭头从侧面变为向下，但是当我点击它时隐藏并且只有当我再次单击它时才出现，请帮助任何人？

$('.linha').bind({
    'click': function(){
        var visible = $('.mais_a').is(':visible');
        $('.mais2').hide();
        if(!visible) $('.mais2').show();
    }

})

          <div id="menu">
            <div id="cutelo"><img src="wp-content/themes/PAA/cutelo.png"></div>

            <div id="linha01" class="linha">
                Festival

                <div class="mais_a">
                    ►&nbsp;
                </div>

                <div class="mais2">▼</div>

            </div>

            <div id="submenu01" class="submenu">


                <div id="submenu01_linha02" class="linha">
                    <a href="<?php echo get_permalink( 37 ); ?>">Homenagens</a>
                </div>

                <div id="submenu01_linha03" class="linha">
                    <a href="<?php echo get_permalink( 41 ); ?>">Como Participar</a>
                </div>

                <div id="submenu01_linha04" class="linha">
                    <a href="<?php echo get_permalink( 43 ); ?>">Regulamento</a>
                </div>
            </div>

这是一个Fiddle

编辑：

是否可以将其改编为

         <div id="menu">
            <div id="cutelo"><img src="wp-content/themes/PAA/cutelo.png"></div>

            <div id="linha01" class="linha">
                Festival

                <div class="mais">
                    ►&nbsp;
                </div>

                <div class="mais2">▼</div>

            </div>

            <div id="submenu01" class="submenu">


                <div id="submenu01_linha02" class="linha">
                    <a href="<?php echo get_permalink( 37 ); ?>">Homenagens</a>
                </div>

                <div id="submenu01_linha03" class="linha">
                    <a href="<?php echo get_permalink( 41 ); ?>">Como Participar</a>
                </div>

                <div id="submenu01_linha04" class="linha">
                    <a href="<?php echo get_permalink( 43 ); ?>">Regulamento</a>
                </div>
            </div>

            <div id="linha02" class="linha">
                Secção 2014

                <div class="mais">
                    ►&nbsp;
                </div>
            </div>

所以我可以在两个.mais div中工作吗？

您需要调整HTML标记和CSS样式，但这应该有效：

<强> HTML

<div id="menu_esquerda">
    <div id="menu">
        <div id="cutelo"><img src="wp-content/themes/PAA/cutelo.png"></div>
        <div id="linha01" class="linha">Festival
            <div class="mais_a">►&nbsp;</div>
            <div class="mais2">▼&nbsp;</div>
        </div>
        <div id="submenu01" class="submenu">
            <div id="submenu01_linha02" class="linha"> <a href="<?php echo get_permalink( 37 ); ?>">Homenagens</a></div>
            <div id="submenu01_linha03" class="linha"> <a href="<?php echo get_permalink( 41 ); ?>">Como Participar</a></div>
            <div id="submenu01_linha04" class="linha"> <a href="<?php echo get_permalink( 43 ); ?>">Regulamento</a></div>
        </div>
        <div id="linha02" class="linha">Secção 2014
            <div class="mais_a">►&nbsp;</div> <!-- Removed the div with class mais_b -->
            <div class="mais2">▼&nbsp;</div> <!-- And re-used the same ones you had before (previous menu item) -->
        </div>
        <div id="submenu02" class="submenu">

    </div>

<强>的Javascript

$(".mais2").hide(); // Hide the down arrows.

$(".linha").on("click", function() {
    // Toggle visibility of element of class mais_a which is a 
    // child of the clicked element.
    $(".mais_a", this).toggle();

    // Toggle visibility of element of class mais2 which is a 
    // child of the clicked element.
    $(".mais2", this).toggle(); 

    // Toggle visibility of element of class submenu which is 
    // the next sibling of the clicked element.
    $(this).next(".submenu").slideToggle(); 
});
