我使用REST api获取帖子内容,删除了所有html标签。
{'post': {'Content': 'test content with #hashtag'}}
我使用filter和regex从内容创建主题标签。
<div v-html="$options.filters.customFilter(post.Content)"></div>
(...)
methods:
ale(tag) {
alert('asdf')
}
customFilter(val) {
val = val.replace(/#(\S*)/g, '<a @click="ale(\'asdf\')" href="http://localhost:8080/tag/$1">$1</a>')
return val
}
问题是这个过滤器会创建html链接并强制整个网页重新加载(而不是路由器方式)
我尝试过@click但是vue没有解释它(在dom中是纯文本@click
)
如何从过滤器触发路由器或@click?
如果我不能有其他方法可以做到这一点?
修改 完整的代码是
<template>
<div class="hello">
<h1>{{ msg }}</h1>
<li v-bind:key="index" v-for="(post, index) in posts">
<div v-html="$options.filters.customFilter(post.Content)"></div>
</li>
</div>
</template>
<script>
export default {
name: 'Posta',
data() {
return {
msg: 'Welcome to Your Vue.js App POST',
posts: []
}
},
methods: {
ale() {
alert('asdf')
}
},
mounted() {
this.posts = [{Content: 'test with #hashtag'}]
},
filters: {
customFilter(val) {
// ...
val = val.replace(/#(\S*)/g, '<a @click="ale(\'asdf\')" href="http://localhost:8080/tag/$1">$1</a>')
return val
}
}
}
</script>
<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
h1,
h2 {
font-weight: normal;
}
ul {
list-style-type: none;
padding: 0;
}
li {
/*display: inline-block;*/
margin: 0 10px;
}
a {
color: #42b983;
}
</style>

而不是使用普通<a>
标记
你必须使用<router-link :to="dynamicValue">
<template>
<div class="hello">
<h1>{{ msg }}</h1>
<li v-for="(post, index) in posts" v-bind:key="index">
<router-link :to="getDynamicUrl(post.Content)">{{post.something}}</router-link>
</li>
</div>
</template>
<script>
export default {
name: 'Posta',
data() {
return {
msg: 'Welcome to Your Vue.js App POST',
posts: []
}
},
methods: {
ale() {
alert('asdf')
},
getDynamicUrl(val) {
return val; //somethingWith val
},
},
mounted() {
this.posts = [{Content: 'test with #hashtag'}]
},
}
</script>

使用@click.prevent
来阻止页面硬加载的默认操作:https://vuejs.org/v2/guide/events.html#Event-Modifiers
然后使用Vue Router push
或其他一些程序化导航来更改vue路线:https://router.vuejs.org/en/essentials/navigation.html
