最近在写一个个人网站，在导航高亮这里，功能实现了，但是href跳转地址怎么写都报错，求大神分析分析原因！

Question

如题！
下边是代码：后台代码：
class Common extends Controller
{
    public function _initialize()
    {
     $nav=Db('nav')->order('navcat asc')->select();
     // print_r($nav);
     $request = Request::instance();
     foreach($nav as $key=>$val){
     $nav[$key]['controller']=strtolower($request->controller());
     }
     $this->assign('nav',$nav);
    }
}
打印出来的数组：
Array
(
    [0] => Array
        (
            [id] => 14
            [navname] => 111
            [navcat] => 1
            [navcontroller] => index
            [controller] => index
        )    [1] => Array
        (
            [id] => 8
            [navname] => 222
            [navcat] => 2
            [navcontroller] => article
            [controller] => index
        )    [2] => Array
        (
            [id] => 9
            [navname] => 333
            [navcat] => 3
            [navcontroller] => novel
            [controller] => index
        )    [3] => Array
        (
            [id] => 10
            [navname] => 444
            [navcat] => 4
            [navcontroller] => music
            [controller] => index
        )    [4] => Array
        (
            [id] => 11
            [navname] => 555
            [navcat] => 5
            [navcontroller] => movie
            [controller] => index
        )    [5] => Array
        (
            [id] => 12
            [navname] => 666
            [navcat] => 6
            [navcontroller] => message
            [controller] => index
        ))html页面的代码<div class="list">
                <ul>
                 {volist name='nav' id='nav_val'}
                 <a {if condition="$nav_val['controller'] == $nav_val['navcontroller']" } class="active" {/if}  href="#"><li>{$nav_val.navname}</li></a>
                 {/volist}
                </ul>
            </div>在html页面中，href的跳转 怎么写？
我最开始写的 href="{:url('$nav_val['navcontroller']/index')}" 运行报错！
拼接方法 href=“{:url(' '+$nav_val['navcontroller']+'/index')}” 还是报错！
希望大神帮忙分析一下
js方法，因为是一个循环，就必须给每个a标签加上id或者class，最后还是因为拼接字符串 ，从晚上七点 卡到现在 实在是头疼。
下面是Jquery 方法的html页面，希望指正
<div class="list">
                <ul>
                 {volist name='nav' id='nav_val'}
                 <script>
                 var aid={$nav_val['id']};
                 var nav="{:url('{$nav_val['navcontroller']}/index')";
                 $("#nav{$nav_val['id']}").attr('href',nav);
                 </script>
                 <a id="nav{$nav_val['id']}" {if condition="$nav_val['controller'] == $nav_val['navcontroller']" } class="active" {/if}  href="#"><li>{$nav_val.navname}</li></a>
                 {/volist}
                </ul>
            </div>

Answer 1

这是tp么?
你看一下最终输出的HTML是什么不就行了

Answer 2

你 href="#" 光摆弄 id 有什么用？

Answer 3

<a {if condition="$nav_val['controller'] == $nav_val['navcontroller']" } class="active" {/if}  href="#"><li>{$nav_val.navname}</li></a>改为：<a {if condition="$nav_val['controller'] == $nav_val['navcontroller']" } class="active" {/if}  href="/show_{$nav_val.id}.html"><li>{$nav_val.navname}</li></a>
