Steps to reproduce
I wrote a demo:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta http-equiv="X-UA-Compatible" content="ie=edge" />
<title>demo</title>
<style>
.link {
cursor: pointer;
user-select: none;
}
</style>
</head>
<body>
<script src="https://unpkg.com/vue/dist/vue.js"></script>
<div id="app">
<transition>
<keep-alive include="foo">
<component :is="target" @change="onChange"></component>
</keep-alive>
</transition>
</div>
<script>
const Foo = {
name: "foo",
template: `<div class="link" @click="$emit('change', 'bar')">Go to Bar</div>`
};
const Bar = {
name: "bar",
template: `<div class="link" @click="$emit('change', 'foo')">Go to Foo</div>`
};
Vue.component("foo", Foo);
Vue.component("bar", Bar);
const app = new Vue({
data: {
target: "foo"
},
methods: {
onChange(target) {
this.target = target;
}
}
}).$mount("#app");
</script>
</body>
</html>The debugging process is as follows:
1 Click "Collect garbage" and "Take heap snapshot"(snapshot 1)
2 Click the routing button on the left 10 times, then click "Collect garbage" and "Take heap snapshot"(snapshot 2)
3 Click the routing button on the left 10 times, then click "Collect garbage" and "Take heap snapshot"(snapshot 3)
The generated "snapshot" is as follows:
snapshot 1:
snapshot 2:
snapshot 3:
After clicking 100 times:
VueComponent is not being recycled, is this a bug?
What is expected?
Why is this happening, is this a bug?
What is actually happening?
Component will not be cleared when switching components.
