Code examples on secondary navigation and highlighting in ThinkPhp3.2

Nothing to do, take notes

The implementation of secondary navigation is a secondary linkage, um

Let’s take a look at the database first. I like to use one table. There are many tables. It won’t be fun anymore

The second-level code name is just the code name of the first-level navigation. It’s simple. Chestnut;

Code part:

Look at the controller, the big head is here:

<?php
namespace Otcms\controller;
use Think\controller;
use Otcms\controller\WxhController;
use Think\index;
class WxhController extends Controller
{
    public function index()
    {
        $cha = M(&#39;article&#39;);
        $chaa = $cha->where("a_keyword = 274")->select();

        foreach($chaa as &$v)
        {

            $aid = $v[&#39;a_id&#39;];

      $aa =  $cha->where("laiyuan = $aid")->select();

            //判断是否有二级菜单

            if(empty($aa))
            {
                $v[&#39;shao&#39;]="";
            }
            else{
                           $v[&#39;shao&#39;]= $aa;

            }

//dump($aa);
        }
        $this->assign(&#39;chaa&#39;,$chaa);



        $this->display(&#39;Wxh:public/25-1index&#39;);
    }



}

Well, the first sql is for first-level navigation, and the second one is for checking. Level navigation,

Look at the front-end code:

    <nav class="nav">
                            <ul class="ul1">

                                <foreach name="chaa" item="ab">

                                    <li class="li1">
                                        <a href="about.html">{$ab.a_title}</a>

                                        <if condition=" $ab[&#39;shao&#39;]  neq &#39;&#39; ">
                                            <ul>

                                                <foreach name="ab[ &#39;shao&#39;] " item="v ">

                                                    <li>
                                                        <a href="about.html ">{$v.a_title}</a>
                                                    </li>

                                                </foreach>

                                            </ul>   
                                            <else />
                                        </if>
                                    </li>

                                </foreach>

                            </ul>
                        </nav>

Here is to determine whether Empty

Highlight:

var pathArray = location.pathname;$aa=$("a[href='"+pathArray+"']").$dd.addClass("current");

These two lines of code can handle most navigation highlighting.

Use when encountering special needs: you can get his parent Level: use parents

<script type="text/javascript">var pathArray = location.pathname;
$("a[href=&#39;"+pathArray+"&#39;]").parents(&#39;li&#39;).addClass("current");
</script>
