我想在wp_nav_menu之后删除

Question

这是我的档案：

<?php
$defaults = array(
'theme_location'  => '',
'menu'            => '',
'container'       => 'div',
'container_class' => true,
'container_id'    => 'btn',
'menu_class'      => true,
'menu_id'         => '',
'echo'            => true,
'fallback_cb'     => 'wp_page_menu',
'before'          => '',
'after'           => '<li class="btn_bar"><img src="img/pic-btn_bar.jpg"/></li>',
'link_before'     => '',
'link_after'      => '',
'items_wrap'      => '<ul>%3$s</ul>',
'depth'           => 0,
'walker'          => ''
);

wp_nav_menu( $defaults );
?>

在这里，我插入class =“btn_bar”＆gt;

<ul>
<li class="menu-item-xxx">ABC</li>
<li class="btn_bar"><img width="18" height="38" src="img/pic-btn_bar.jpg"></li>
<li class="menu-item-xxx">DEF</li>
<li class="btn_bar"><img width="18" height="38" src="img/pic-btn_bar.jpg"></li>
</ul>

我想将代码放在菜单的第一个或最后一个菜单中。请帮帮我

Answer 1

听起来你可以用CSS而不是PHP / HTML来做这件事。使用CSS，您可以定位特定的菜单项，并使用伪后插入图像。

.menu-item-82:after {  
content: " ";    
position: relative;
background: url(images/nav-image.png) -1px -32px #ddd;  
display: block;  
height: 25px;  
width: 25px;  
}

Answer 2

另一个简单的css hack，只要你确定了你的菜单项id

#menu-item-1244 .delimiter {display:none;}

Answer 3

<script type="text/javascript">
        jQuery(document).ready(function(){
            jQuery("#doctype li:first").after("<li class='btn_bar'><img src='http://i.stack.imgur.com/VNk7r.jpg?s=24&g=1'/></li>");
            jQuery("#doctype li:last").after("<li class='btn_bar'><img src='http://i.stack.imgur.com/VNk7r.jpg?s=24&g=1'/></li>");
        });
</script>    

<?php
$defaults = array(
    'theme_location'  => 'primary',
    'menu'            => 'Menu 1',
    'container'       => 'div',
    'container_class' => '',
    'container_id'    => 'doctype',
    'menu_class'      => '',
    'menu_id'         => '',
    'echo'            => true,
    'fallback_cb'     => 'wp_page_menu',
    'before'          => '',
    'after'           => '',
    'link_before'     => '',
    'link_after'      => '',
    'items_wrap'      => '<ul class="filter">%3$s</ul>',
    'depth'           => 0,
    'walker'          => ''
);

wp_nav_menu( $defaults );
?>
