1.前言
前面把vue大部分重要的内容学完了，其实vue还是非常容易上手的。我学习vue的目的就是它挺好用的，所以我一直在想怎么把vue整合到后台中，写出好看的页面。本篇博客会讲到：
1.我们后台怎么改成vue的
2.vue能给我们带来什么便捷
3.增删改查-vue.js 模板
2.效果展示
反正我觉得用了vue之后，我们对数据的展示方便了许多，个人认为是我目前最喜欢的一款框架。
3.vue-页面框架搭建

var vm = new Vue({
el:'#rrapp',
data:{
user:{},
menuList:{},
main:"main.html",
password:'',
newPassword:'',
navTitle:"控制台"
},
methods: {
getMenuList: function (event) {
$.getJSON("sys/menu/nav?_"+$.now(), function(r){
vm.menuList = r.menuList;
});
},
getUser: function(){
$.getJSON("sys/user/info?_"+$.now(), function(r){
vm.user = r.user;
});
},
},
created: function(){
this.getMenuList();
this.getUser();
},
updated: function(){
//路由
var router = new Router();
routerList(router, vm.menuList);
router.start();
}
});
function routerList(router, menuList){
for(var key in menuList){
var menu = menuList[key];
if(menu.type == 0){
routerList(router, menu.list);
}else if(menu.type == 1){
router.add('#'+menu.url, function() {
var url = window.location.hash;
//替换iframe的url
vm.main = url.replace('#', '');
//导航菜单展开
$(".treeview-menu li").removeClass("active");
$("a[href='"+url+"']").parents("li").addClass("active");
vm.navTitle = $("a[href='"+url+"']").text();
});
}
}
}
//iframe自适应
$(window).on('resize', function() {
var $content = $('.content');
$content.height($(this).height() - 120);
$content.find('iframe').each(function() {
$(this).height($content.height());
});
}).resize();左侧菜单从数据库查出来，然后用了vue自定义的组件menu-item：
<!-- 左侧菜单 -->
<aside class="main-sidebar">
<section class="sidebar">
<ul class="sidebar-menu">
<li class="header">导航菜单</li>
<!-- 自定义vue组件生成的菜单 -->
<menu-item :item="item" v-for="item in menuList"></menu-item>
</ul>
</section>
</aside>//注册菜单组件
Vue.component('menuItem',menuItem);
//生成菜单
var menuItem = Vue.extend({
name: 'menu-item',
props:{item:{}},
template:[
'<li>',
' <a v-if="item.type === 0" href="javascript:;">',
' <i v-if="item.icon != null" :class="item.icon"></i>',
' <span>{{item.name}}</span>',
' <i class="fa fa-angle-left pull-right"></i>',
' </a>',
' <ul v-if="item.type === 0" class="treeview-menu">',
' <menu-item :item="item" v-for="item in item.list"></menu-item>',
' </ul>',
' <a v-if="item.type === 1 && item.parentId === 0" :href="\'#\'+item.url">',
' <i v-if="item.icon != null" :class="item.icon"></i>',
' <span>{{item.name}}</span>',
' </a>',
' <a v-if="item.type === 1 && item.parentId != 0" :href="\'#\'+item.url"><i v-if="item.icon != null" :class="item.icon"></i><i v-else class="fa fa-circle-o"></i> {{item.name}}</a>',
'</li>'
].join('')

return ;
}
confirm('确定要删除选中的记录？', function(){
$.ajax({

url: baseURL + "sys/dept/delete",
data: "deptId=" + deptId,
success: function(r){
if(r.code === 0){
alert('操作成功', function(){

});
}else{
alert(r.msg);
}
}
});
});
},
reload: function () {
vm.showList = true;
Dept.table.refresh();
}
}
});增加和修改用到了同个界面，并且更加v-show，将增加，删除，修改按钮隐藏掉，然后显示增加/修改操作界面，仅仅换一下标题就可以。
