vue

1、声明私有过滤器和全局过滤器

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<div id="app">
    <p>message的值是：{{message | capi}}</p>
</div>
<script src="lib/vue-2.6.12.js"></script>
<script>
    <!-- 定义全局过滤器 -->
    Vue.filter('capi', (str) => {
        const first = str.charAt(0).toUpperCase()
        const other = str.slice(1)
        return first + other
    })
    const vm = new Vue({
        el: '#app',
        data: {
            message: 'hello vue.js'
        },
        methods: {},
        // 私有过滤器
        filters: {
            capi(val) {
                const first = val.charAt(0).toUpperCase()
                const other = val.slice(1)
                return first + other
            }
        }
    })</script>
</body>
</html>
