本範例使用json資料,拼接ul和li來實現的

2.html代碼:




複製程式碼

代碼如下:
3.解析json資料(plugin-menu.js檔):剛學會寫jquery插件,寫的還比較亂,湊合著看吧



複製程式碼
程式碼如下:

(function($){
    $.fn.extend({
        選單:函數(選項          資料:[],
ulId:"baseMenu"
            };
             li
            $.each(options.data,function(i, v){
                var li = $("
  • "' name='" options.data[i].pid "'> ");
                    var _a = $("
    " options.data[i].name "");                   .appendTo(li);

                     li.appendTo($("#" options.ulId));
                });
                // 為li新增事件
                $(this).find("li id = $(this).attr("id ");
                    $(this).find("ul[name='" id "']").show();
              var id = $(this) .attr("id ");
                    $(this).find("ul[name='" id "']").hide();    } );
    })(jQuery);


    支持因為無限級,所以肯定會使用分區方法:




    複製代碼


    程式碼如下:


  • function _each(data,li){
        if(data==undefined||data.children==undefined){  >    }    var ul = $("
      ");     $.each(data. child,function(i,v){
              var _li = $("
    • ");        var _a = $("" data.children[i].name "");
    •      . attr("href",data.children[i].url)
                  .attr("target","_blank")
            if( data.children[ i].children!=undefined){
                  _each(data.children[i],_li);
            ;
          ul.appendTo 。 :


      $(function() {
          $("#menu").menu({data:menuData,ulId:"baseMenu"});
      } );


      最後,css樣式:




      複製程式碼


      程式碼如下:

      ul,li{list-style:none;padding:0px;margin:0px;}
      #menu *{line-height:30px;}
      #menu a{text-decoration:無;}
      #menu ul{text-align:left;}
      #menu>ul>li{text-align:center;width:80px;float:left;}
      #menu>ul> li>a{顏色:#000;}
      #menu>ul>li:hover{背景:#F0F0F0;}
      #menu>ul>li ul{顯示:無;寬度:150px;位置:絕對;背景:#c1cd94;box-shadow:2px 2px 2px #000;-webkit-box-shadow:2px 2px 2px #000;
      -moz-box-shadow:2px 2px 2px #123; #選單>ul>li>ul li{padding-left:5px;位置:相對;}
      #menu>ul>li>ul li>a{color:#000;}
      #menu>ul> li>ul li:hover{背景:#d3dbb3;}
      #選單>ul>li>ul>li ul{左:150px;頂部:0px;}
