<template>
<div id="app">
<h1>高亮关键词</h1>
<input type="text" v-model="keyword" />
<p class="text" v-html="highLightWord(text, keyword)"></p>
</div>
</template>
<script>
export default {
data() {
return {
keyword: '高亮',
text: '如果你在输入框输入匹配到的词,就会高亮<br>If you enter the word matching in the input box, it will highlight',
}
},
methods: {
highLightWord(text, keyword) {
if (!keyword) return text
const regExp = new RegExp(keyword, 'gi')
if (regExp.test(text)) {
text = text.replace(regExp, '<mark>$&</mark>')
}
return text
},
},
}
</script>
