视频总结 1

class和style:
:class="" v-bind:class=""
:style="" v-bind:style=""

:class="[red]" red是数据
:class="[red,b,c,d]"

:class="{red:a, blue:false}"

:class="json"

data:{
json:{red:a, blue:false}
}
--------------------------
style:
:style="[c]"
:style="[c,d]"
注意: 复合样式，采用驼峰命名法
:style="json"
-----------------------------------------
模板:
{{msg}} 数据更新模板变化
{{*msg}} 数据只绑定一次

{{{msg}}} HTML转意输出

过滤器:-> 过滤模板数据
系统提供一些过滤器:

{{msg| filterA}}
{{msg| filterA | filterB}}

uppercase eg: {{'welcome'| uppercase}}
lowercase
capitalize

currency 钱

{{msg| filterA 参数}}

事件:
v-on:click/mouseover......

简写的:
@click="" 推荐

事件对象:
@click="show($event)"
事件冒泡:
阻止冒泡:
a). ev.cancelBubble=true;
b). @click.stop 推荐
默认行为(默认事件):
阻止默认行为:
a). ev.preventDefault();
b). @contextmenu.prevent 推荐
键盘:
@keydown $event ev.keyCode
@keyup

常用键:
回车
a). @keyup.13
b). @keyup.enter
上、下、左、右
@keyup/keydown.left
@keyup/keydown.right
@keyup/keydown.up
@keyup/keydown.down
.....

 v-on:click="a=false"
过滤器
 {{12|currency '￥'}}
  {{'WELCOME'|lowercase|capitalize}}
<button class="btn btn-primary btn-sm" data-toggle="modal" data-target="#layer" v-on:click="nowIndex=$index">删除</button>

交互:
$http （ajax）

如果vue想做交互

引入: vue-resouce

get:
获取一个普通文本数据:

获取一个普通文本数据:
        this.$http.get('aa.txt').then(function(res){
            alert(res.data);
        },function(res){
            alert(res.status);
        });
        给服务发送数据:√
        this.$http.get('get.php',{
            a:1,
            b:2
        }).then(function(res){
            alert(res.data);
        },function(res){
            alert(res.status);
        });
this.$http.get
post
this.$http.post('post.php',{
            a:1,
            b:20
        },{
            emulateJSON:true
        }).then(function(res){
            alert(res.data);
        },function(res){
            alert(res.status);
        });
this.$http.post
