如何使用angularjs处理动态菜单,第1张

angularjs处理动态菜单的实现方法：

1、核心angularjs代码：

var testImg=angular.module("appTest",["ms.leafMenu"])

.controller('testCtr',['$scope',function($scope){

$scope.data=[{"id":"1","pid":"0","name":"第一行","children":[{"id":"3","pid":"1","name":"第一行1.1"},{"id":"4","pid":"1","name":"第一行1.2"}]},{"id":"2","pid":"0","name":"第二行","children":[{"id":"5","pid":"2","name":"第二行2.1"}]}]

}])

angular.module("ms.leafMenu",[])

.directive('msLeafMenu',['$compile',function($compile){

return {

restrict:'EA',

transclude: true,

replace: false,

//template:"<li></li>",

scope:{

data:'=?',

id:'@?',

pid:'@?',

pvalue:'@?',

showname:'@?',

isstandard:'@?'

link:function(scope,element,attrs,leafController){

创建节点数据的方法：

function createTreeData(id,pid,pvalue){

var newData=[]

angular.forEach(scope.data,function(item,index){

if(item[pid]==pvalue){

var children=createTreeData(id,pid,item[id])

if(children &&children.length>0){

item.children=children

}

newData.push(item)

}

})

return newData

}

if(!scope.isstandard){

scope.data=createTreeData(scope.id,scope.pid,scope.pvalue)

}

//向节点增加数据

element.append($compile('<ul class="ms_leaf_menu_group"><li ng-repeat="row in data" ng-class="{ms_parent_item:(row.children &&row.children.length>0),ms_child_item:(!row.children || row.children.length<=0)}"><div ng-click="toogle($index)"><a >{{row[showname]}}</a><span class="glyphicon" ng-class="{\'glyphicon-chevron-right\':(row.children &&row.children.length>0 &&!row.isopen),\'glyphicon-chevron-down\':(row.children &&row.children.length>0 && row.isopen)}" aria-hidden="true"></span></div><div ng-show="row.isopen"><ms-leaf-menu data="row.children" id="id" pid="pid" showname="{{showname}}" pvalue="{{row[id]}}"></ms-leaf-menu></div></li></ul>')(scope))

//此处是关键，调用入口处，需要找到index

scope.toogle=function(index){

scope.data[index]["isopen"]=!scope.data[index]["isopen"]

}

}])

</script>

2、html代码：

<ms-leaf-menu data="data" id="id" pid="pid" showname="name" pvalue="0"></ms-leaf-menu>

</div>

</body>

3、效果图

首先，表格采用的是BootStrap样式编辑的，主要使用的是angularjs，为了方便也有jQuery的方法，在测试时需自行引入bootstrap，angularjs和jq的文件。

整体代码预览：

HTML：

<!DOCTYPE html>

<head>

//需要自行引入BOOTStrap，angularjs和jQuery的js，css文件

<style>

.pagination .num{

font-size:22pxcolor:red

}

.text{

margin:0 auto

border:1px solid #ccc

width:100%

max-width:200px

}

</style>

</head>

<div class="muted pull-left">{{kaohzbTitle}}</div>

</div>

<button style="margin-left: 5px" id="refresh" ng-click="refresh()"

class="btn btn-success">

<i class=" icon-refresh icon-white"></i>刷新

</button>

<button ng-disabled="isdisabled" class="btn" ng-class="{'btn-info':isInfo}" id="savekaohzb"

ng-click="save()">

<i class="icon-edit icon-white"></i>保存

</button>

</div>

<table class="table table-striped table-bordered table-hover"

id="example" style="margin-top:10px">

<thead>

<tr>

<th style="text-align: centerwidth: 150pxvertical-align: middle" rowspan="2">玩家支持队伍</th>

</tr>

<tr>

</tr>

</thead>

<td style="text-align:center">{{tb.zbname}}</td>

<td style="text-align:center">{{tb.zbtime}}</td>

<td style="text-align:center">{{tb.zbrul1}}</td>

<td style="text-align:center">{{tb.zbrul2}}</td>

<td style="text-align:center">{{tb.zbrul2}}</td>

<td style="text-align:center">{{tb.zbrul1}}</td>

<td style="text-align:center">{{tb.score}}</td>

<td>

</select>

</td>

</tr>

</tbody>

</table>

</div>

</ul>

</li>

</ul>

<span>

当前为第<span class="num" id="current_page"></span>页，总共<span class="num" id="page_all"></span>页

</span>

<span>您当前对select的操作值为:</span>{{typename}}

</div>

</div>

</body>

js代码：

angular.module("myModule",[]).controller('myCtrl', function($scope) {

$scope.kaohzbTitle = "考核指标维护"

$scope.search = new Object()

$scope.isdisabled=false

$scope.isInfo=false

$scope.saveDate=""//用于保存得到的原始数据

// $http.post请求表格数据

// 模仿请求得到的数据
