我们在使用织梦系统制作网站时经常会遇到网站栏目较多，显示当前栏目下的二级与三级栏目时，使用栏目嵌套标签，但是当三级栏目为空时，会显示同级栏目。从用户体验角度出发，常理情况下也是需要空白的，即二级栏目下的三级栏目如为空时，则不显示。那么如何让织梦{dede:channel type='son'}无子栏目时不显示同级栏目呢？

作为一个web前端，一款顺手的编辑器是必不可少的，我个人是一个st的忠实粉丝，不管是界面，还是功能，还是流畅度都十分让人爱不释手。她的插件也是很多的，她的更多神奇之处我就不多讲，只要你用了你就会知道。
下面就单独说说如何利用sublime删除代码中的空行或者删除全部空格将代码压缩。

/**
 * 获取字符串s中出现re的次数
 *
 * @param      {(Function|string)}  re      正则式
 * @param      {string}             s       字符串
 * @return     {string}             出现次数
 */
function patch(re,s){
    re=eval("/"+re+"/ig"); //不区分大小写，如须则去掉i,改为 re=eval("/"+re+"/g")
    var len = s.match(re).length;
    return len;
}

方式2：
var s='jhdoiweesdds';
var n=(s.split('d')).length-1;

打开/plus/search.php文件，对应位置插入以下代码：

if($mobile){
    define('DEDEMOB', 'Y');
}

或：
复制plus/search.php为search_m.php，修改13行require_once(DEDEINC."/arc.searchview.classm.php");
复制include/arc.searchview.class.php为include/arc.searchview.classm.php，修改131$GLOBALS['cfg_df_style']."/search_m.htm";
即可使用search_m.php搜索

一、添加字段
首先是要在数据库添加字段，英文栏目名enname，栏目图图片typelitpic，添加完后如下图
如果懒得麻烦就直接在DEDE后台或者在数据库添加SQL命令，（DEDE后台-系统-SQL命令行工具）
alter table dede_arctype add enname char(100) NOT NULL default ''; alter table dede_arctype add typelitpic char(255) NOT NULL default '';

$.imgview({'url':'app.png'});

JS下载：jquery-imgview.rar

追加随机数进行刷新：window.location.href=window.location.href+"?id="+10000*Math.random();

  animationDuration: 600,         //Integer: Set the speed of animations, in milliseconds动画淡入淡出效果延时
  directionNav: true,             //Boolean: Create navigation for previous/next navigation? (true/false)是否显示左右控制按钮

  start: function(){},            //Callback: function(slider) - Fires when the slider loads the first slide
  before: function(){},           //Callback: function(slider) - Fires asynchronously with each slider animation
  after: function(){},            //Callback: function(slider) - Fires after each slider animation completes
  end: function(){}               //Callback: function(slider) - Fires when the slider reaches the last slide (asynchronous)
  
 });
