递归函数

深度遍历树结构时用了递归函数：

function fillList() {
    $("tbody").html("");
    var htmlStr="";
    if (C_module&&C_module.length>0) {
      for (var i=0; i<C_module.length; i++) {
        deepTraverFill(C_module[i], htmlStr);
      }
    }
    $('.tree').treegrid();
    function deepTraverFill(treeNode, htmlStr) {
      moduleArr.push(treeNode);
      if (!treeNode) return;
      htmlStr= "<tr class='treegrid-" + (treeNode.id) + ( (treeNode.pId=='0'||!treeNode.pId)?"":" treegrid-parent-" + (treeNode.pId)) + "'>" +
        "<td class='tdLeft'>" + treeNode.moduleName + "</td>" +
        "<td>" + treeNode.url + "</td>" +
        "<td>" + (treeNode.isValidate==1?"有效":"无效") + "</td>"+
        "<td>"+
          "<button type='button' class='btn btn-primary btn-xs' data-toggle='modal' data-target='#myModal' onclick=showUpdateModal('" + treeNode.id + "')>编辑</button>"+
          "<button type='button' class='btn btn-danger btn-xs del' onclick=deleteData('" + treeNode.id + "')>删除</button>"+
        "</td></tr>";
        $("tbody").append(htmlStr);
      if (treeNode.moduleList&&treeNode.moduleList.length>0) {
        for (var i=0; i<treeNode.moduleList.length; i++) {
          deepTraverFill(treeNode.moduleList[i], htmlStr);
        }  
      }
    }
  }
