set(value) { this.$emit('update:visible', value) }

这是一个 Vue.js 组件中的属性 setter 方法,用于接收一个新值并将其设置为组件属性 "visible" 的值。同时,它通过调用 `$emit` 方法向父组件发出一个名为 "update:visible" 的事件,并将新的值作为参数传递给父组件。这样,父组件就能够监听这个事件,从而更新自己的状态或属性。需要注意的是,在父组件中要使用 `v-model` 指令来绑定这个属性,才能够让它具有双向数据绑定的功能。

this.$emit('update:isShow', false) 是子组件中的代码,它的作用是在子组件中触发一个名为"update:isShow"的自定义事件,并将false作为参数传递给父组件。
this.$emit('update:visible', false) 是另一个子组件中的代码,它的作用是在子组件中触发一个名为"update:visible"的自定义事件,并将false作为参数传递给父组件。
在父组件和子组件之间传递值时,如果想要在子组件中改变父组件的值,可以在父组件中使用.sync修饰符。具体语法是:this.$emit('update:props中的值',要改变的值)。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

this.$emit update
This code snippet is using Vue.js, a popular JavaScript framework for building user interfaces. The `$emit` method is used to emit an event from a child component to its parent component. In this case, the parent component is listening for the `update` event and will execute the corresponding code when it receives the event.
Here's an example of how you might use this code in a Vue.js component:
```javascript
// Child component
this.$emit('update');
```
And in the parent component, you would listen for the `update` event and handle it accordingly:
```javascript
// Parent component
<template>
<div>
<!-- Your template code here -->
</div>
</template>
<script>
export default {
mounted() {
this.$on('update', () => {
// Code to execute when the update event is received
console.log('Update event received');
});
},
};
</script>
```
