千峰商城-springboot项目搭建-39-vue插槽作用域
1.组件定义：
定义组件时，将组件中的数据绑定到slot标签。
Vue.component("page-frame",{
template:`<div>
<div id="header" style="width:100%; height:100px; background:pink">
<slot name="s1"></slot>
</div>
<div style="width:100%; height:510px">
<slot name="s2" v-bind:musics="songs"></slot>
</div>
<div id="footer" style="width:100%; height:40px; background:lightgray">{{cr}}</div>
</div>`,
props:["title","cr"],
data:function(){
return{
songs:[
{
"id":001,
"name":"逆战",
"artists":[
{
"id":01,
"name":"张杰"
}
]
},
{
"id":002,
"name":"隐形",
"artists":[
{
"id":02,
"name":"张韶涵"
}
]
}
]
};
}
})
2.引用组件时，在填充插槽的模板上使用slot-scopt属性获取插槽绑定的值。
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <link rel="stylesheet" href="css/bootstrap.css" /> <script type="text/javascript" src="js/jquery-1.7.2.min.js"></script> <script type="text/javascript" src="js/bootstrap.js"></script> <script type="text/javascript" src="js/vue.js"></script> </head> <body> <div id="container"> <page-frame title="标题" cr="千峰武汉"> <template slot="s1"> <input type="text"/><button type="button">搜索</button> </template> <!--在使用模板填充组件插槽时，可以使用slot-scope属性获取组件插槽绑定的数据--> <template slot="s2" slot-scope="res"> <table class="table table-bordered table-condensed"> <tr> <th>序号</th> <th>歌曲id</th> <th>歌名</th> <th>歌手</th> <th>操作</th> </tr> <tr v-for="song,index in res.musics"> <td>{{index+1}}</td> <td>{{song.id}}</td> <td> {{song.name}} </td> <td> <span v-for="artist in song.artists"> {{artist.name}}</span> </td> <td width="18%"> <button type="button" class="btn btn-primary btn-xs">播放</button> </td> </tr> </table> </template> </page-frame> </div> <script type="text/javascript" src="js/vue.js" ></script> <script type="text/javascript" src="js/my-components.js" ></script> <script type="text/javascript"> var vm = new Vue({ el:"#container" }); </script> </body> </html>
