自動化發佈系統在選擇文件時，使用jQuery EasyUI 建立頁面樹形菜單(Tree) 及後端python 遞歸實現Easyui combotree 樹。這裏主要分享2點： css

一、linux 中 python 遞歸實現Easyui combotree 樹 html

二、jQuery EasyUI就不用介紹了，一款輕量級UI框架，集成了各類用戶界面插件。前端

關於jQuery EasyUI 能夠參考： http://www.w3cschool.cc/jeasyui/jqueryeasyui-tutorial.html java

關於自動化發佈系統，能夠查看：http://my.oschina.net/u/588586/blog/345670 python

本文環境基礎：http://my.oschina.net/u/588586/blog/345675 jquery

目的：用戶在頁面選擇對應項目，前端展現對應項目svn目錄列表 linux

一、廢話很少說，先上圖看看UI

選擇項目時，展現項目目錄的 tree ajax

二、jQuery EasyUI tree 代碼 html

##須要調用easyui.css 和 jquery.easyui.min.js npm

    </html>

三、js代碼

能夠放在index.html文件後面，根據所選擇項目id，後端生成tree文件

    <script>
        $("#DeployProject").change(function(){
                var project_id=$("#DeployProject").val();
                //後端刷新tree json文件
                $.ajax({
                    type:"POST",
                    url:"/",
                    data:{'type':"select_project",'project_id':project_id},
                    success:function(response){
                        //alert(response);
                        // tree 
                        $("#file_list").tree({
                                // 記得加上new Date() ，緣由是cache問題 ；有興趣你試試不加，更改目錄文件看看
                                url:'/static/data/tree_data_'+project_id+'.json?tm=' + new Date(),
                                method:'get',
                                animate:true,
                                checkbox:true
                        });
                        $('#file_list').tree('reload');
                    },
                    error:function(xhr,textStatus){
                        alert(textStatus);
                    }
                });
        });
    </script>

四、python 遞歸實現Easyui combotree 樹，後端pyhton代碼

views.py 文件

from django.shortcuts import render,render_to_response
from django.http import HttpResponse,HttpResponseRedirect
import time,json,os,commands,urllib,sys,subprocess,datetime,signal
#coding=utf-8
#import time,simplejson,json,os,commands
##
default_encoding = 'utf-8'
if sys.getdefaultencoding() != default_encoding:
        reload(sys)
        sys.setdefaultencoding(default_encoding)

# Create your views here.
def index(req):
        ##
        if req.method == 'POST':
                if req.POST.has_key('type') and req.POST['type']=="select_project":
                        project_id=req.POST['project_id']
                        ##調用CreateDirTree函數
                        CreateDirTree('/data/myproject/static/','/data/myproject/static/data/tree_data_'+str(project_id)+'.json')
                        return HttpResponse("ok")
        #return HttpResponse("aa")
        return render_to_response('index.html',)

## 建立文件樹SVN
## python遞歸實現Easyui combotree樹
def CreateDirTree(path,file_json):
        global id_num
        id_num=0
        def createDict(path):
                global id_num
                tree_list=[]
                pathList = os.listdir(path)
                if '.svn' in pathList:
                        pathList.remove('.svn')
                for i,item in enumerate(pathList):
                        id_num+=1
                        children_map={}
                        children_map['id']=id_num
                        children_map['text']=item
                        #children_map['checked']='true'
                        children_map['attributes']={'url':path}
                        if isDir(getJoinPath(path,item)):
                                path = getJoinPath(path,item)
                                tmp_listdir=os.listdir(path)
                                if '.svn' in tmp_listdir:
                                        tmp_listdir.remove('.svn')
                                if  len(tmp_listdir) != 0:
                                        children_map['state']='closed'
                                        """開始遞歸子節點"""
                                        children_map['children'] = createDict(path)
                                tree_list.append(children_map)
                                path = '/'.join(path.split('/')[:-1])
                        else:
                                tree_list.append(children_map)
                return tree_list

        '''合併路徑和目錄，返回完整路徑'''
        def getJoinPath(path,item):
                return os.path.join(path,item)

        '''判斷是否爲目錄'''
        def isDir(path):
                if os.path.isdir(path):
                        return True
                return False

        '''返回json格式數據'''
        def getJson(treestr):
                return json.dumps(treestr)

        '''json 文件'''
        tree_list=createDict(path)
        fjson = getJson(tree_list)
        with open(file_json,'w') as lf:
                lf.write(fjson)
        ##end

生成的文件格式以下：

[{"text": "css", "state": "closed", "children": [{"text": "bootstrap.css", "id": 2, "attributes": {"url": "/data/myproject/static/css"}}, {"text": "bootstrap-theme.min.css", "id": 3, "attributes": {"url": "/data/myproject/static/css"}}, {"text": "bootstrap.min.css", "id": 4, "attributes": {"url": "/data/myproject/static/css"}}, {"text": "bootstrap.css.map", "id": 5, "attributes": {"url": "/data/myproject/static/css"}}, {"text": "bootstrap-theme.css", "id": 6, "attributes": {"url": "/data/myproject/static/css"}}, {"text": "bootstrap-theme.css.map", "id": 7, "attributes": {"url": "/data/myproject/static/css"}}], "id": 1, "attributes": {"url": "/data/myproject/static/"}}, {"text": "js", "state": "closed", "children": [{"text": "bootstrap.js", "id": 9, "attributes": {"url": "/data/myproject/static/js"}}, {"text": "bootstrap.min.js", "id": 10, "attributes": {"url": "/data/myproject/static/js"}}, {"text": "npm.js", "id": 11, "attributes": {"url": "/data/myproject/static/js"}}, {"text": "jquery-1.11.1.min.js", "id": 12, "attributes": {"url": "/data/myproject/static/js"}}], "id": 8, "attributes": {"url": "/data/myproject/static"}}, {"text": "data", "state": "closed", "children": [{"text": "tree_data_0.json", "id": 14, "attributes": {"url": "/data/myproject/static/data"}}, {"text": "tree_data_1.json", "id": 15, "attributes": {"url": "/data/myproject/static/data"}}], "id": 13, "attributes": {"url": "/data/myproject/static"}}, {"text": "fonts", "state": "closed", "children": [{"text": "glyphicons-halflings-regular.ttf", "id": 17, "attributes": {"url": "/data/myproject/static/fonts"}}, {"text": "glyphicons-halflings-regular.svg", "id": 18, "attributes": {"url": "/data/myproject/static/fonts"}}, {"text": "glyphicons-halflings-regular.woff", "id": 19, "attributes": {"url": "/data/myproject/static/fonts"}}, {"text": "glyphicons-halflings-regular.eot", "id": 20, "attributes": {"url": "/data/myproject/static/fonts"}}], "id": 16, "attributes": {"url": "/data/myproject/static"}}]
