类似js中的slot插槽功能,该功能在ArkTS中使用@Builder和@BuilderParam方式来实现 参考链接:https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/arkts-builderparam-0000001820999553 用@Builder插入内容,@Builder中使用if做条件渲染,demo如下:
@Component
struct Child {
@State temp:boolean = true
label: string = `Child`
[@Builder](/user/Builder) FunABuilder0() {}
[@Builder](/user/Builder) FunABuilder1() {}
[@BuilderParam](/user/BuilderParam) aBuilder0: () => void = this.FunABuilder0;
[@BuilderParam](/user/BuilderParam) aBuilder1: () => void = this.FunABuilder1;
build() {
Column() {
this.aBuilder0()
this.aBuilder1()
}
}
}
@Entry
@Component
struct Parent {
label: string = `Parent`
@State temp:boolean = true
[@Builder](/user/Builder) componentBuilder() {
Button('click')
.onClick(()=>{
this.temp = !this.temp
})
if(this.temp){
Text(`${this.label}`)
}
}
build() {
Column() {
this.componentBuilder()
Child({temp: this.temp, aBuilder0: this.componentBuilder, aBuilder1: ():void=>{this.componentBuilder()} })
}
}
}

在HarmonyOS鸿蒙Next中,arkts(ArkUI TypeScript)实现多个插槽主要依赖于<slot>
标签和组件的slots
属性。以下是一个简单的demo,展示如何在自定义组件中实现和使用多个插槽:
自定义组件(MyComponent.ark):
<template>
<div class="container">
<slot name="header"></slot>
<div class="content">
<slot></slot> <!-- 默认插槽 -->
</div>
<slot name="footer"></slot>
</div>
</template>
<script>
export default {
name: 'MyComponent',
};
</script>
<style scoped>
.container {
display: flex;
flex-direction: column;
}
.content {
flex: 1;
}
</style>
使用自定义组件(App.ark):
<template>
<MyComponent>
<template #header>
<div>Header Content</div>
</template>
<div>Main Content</div>
<template #footer>
<div>Footer Content</div>
</template>
</MyComponent>
</template>
<script>
import MyComponent from './MyComponent.ark';
export default {
components: {
MyComponent,
},
};
</script>
上述代码展示了如何定义一个带有三个插槽(一个默认插槽和两个具名插槽)的自定义组件,并在父组件中使用这些插槽。如果问题依旧没法解决请联系官网客服,官网地址是:https://www.itying.com/category-93-b0.html
