在下面的示例中,我想要一个将数字加倍的组件。此数字不是作为属性传递的,而是作为内容传递的。如何在Vue中获得内容值?
var twice = {
template: '<div>{{ value }}</div>',
computed: {
value() {
return parseInt(this.$slot) * 2;
}
}
};
new Vue({
el: '#app',
components: {
twice: twice
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.1.10/vue.min.js"></script>
<div id="app">
<twice>21</twice>
</div>

您可以通过this.$slots.default[0].text
访问默认的广告位文字:
var twice = {
template: `<div>
number : <slot></slot><br>
<div>double : {{ value }}</div>
</div>`,
computed: {
value() {
return parseInt(this.$slots.default[0].text) * 2;
}
},
mounted() {
console.log(this.$slots.default[0].text)
}
};
new Vue({
el: '#app',
components: {
twice: twice
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<twice>21</twice>
<div>
</div>
</div>
