【问题描述】:
我正在尝试开发一个编译给定 html 的组件;我成功地使用了恒定的 html 文本,但我无法通过更改 html 文本来完成这项工作。
main.js
app.component("dyno-html", {
props: ["htmlTxt"],
setup(props) {
watchEffect(() => {
console.log(`htmlText is: ` + props.htmlTxt);
return compile(props.htmlTxt);
});
return compile(props.htmlTxt);
},
});
Home.js
<template>
<div class="home">
<dyno-html
:htmlTxt="html2"
:bound="myBoundVar"
@buttonclick="onClick"
></dyno-html>
-------------
<dyno-html
:htmlTxt="html"
:bound="myBoundVar"
@buttonclick="onClick"
></dyno-html>
</div>
</template>
<script>
export default {
name: "Home",
components: {},
data: function() {
return {
html: "",
html2: `<div> Static! <button @click="$emit('buttonclick', $event)">CLICK ME</button></div>`
};
},
mounted() {
// get the html from somewhere...
setTimeout(() => {
this.html = `
<div>
Dynamic!
<button @click="$emit('buttonclick', $event)">CLICK ME</button>
</div>
`;
}, 1000);
},
methods: {
onClick(ev) {
console.log(ev);
console.log("You clicked me!");
this.html2 = "<b>Bye Bye!</b>";
},
},
};
</script>
htmlText的变化好像到了setup函数,但不影响compile函数!
