局部过滤器：

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">
        <title>filters</title>
        <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js" type="text/javascript" charset="utf-8"></script>
    </head>
    <body>
        <div id="app">
            <input type="text" v-model="test" placeholder="请输入"/>
            <div>{{test|filter1|filter2}}</div>
        </div>
    </body>
</html>
<script type="text/javascript" charset="utf-8">
    var app = new Vue({
        el: "#app",
        data: {
            test: ''
        },
        filters: {
            filter1: function(val) {
                return val.toUpperCase();
            },
            filter2: function(val) {
                var reg = /d/g;
                return val.replace(reg, '*');
            }
        }
    });
</script>
