[英]Getting data from slot-scope
<template slot="item-template" slot-scope="{ item }">
<div class="typeahead-value">{{ item.partnerName }} </div>
<div class="typeahead-info">
<b>Eori:</b> {{ item.partnerEori }} <br>

</div>
</template>
Is there any way, i can get the value item.partnerName so i can put that value in a validation?Or any value 有什么办法可以获取值item.partnerName以便将该值放入验证中?或任何值
It is not clear why you can't access item
but within your slot you should be able to access item
. 目前尚不清楚为什么您无法访问item
但您应该可以在插槽内访问item
。 item
is a property which is accessible via destructuring of the slotProps
item
是可以通过slotProps
来访问的slotProps
<template v-slot:item-template="{ item }">
<p>You can access item here</p>
</template>
To pass in item
as a variable, you can add it to your slot component 要将item
作为变量传递,您可以将其添加到广告位组件中
<slot
name="item-template"
:item="item"
></slot>
Regarding to your questions in the comments 关于您在评论中的问题
This is just a basic example showing how to create a slot component and consume it. 这只是一个基本示例,显示了如何创建和使用插槽组件。
This example slot component InputItem takes in a input field (slot) and emits an event when the value got updated 该示例插槽组件InputItem接受一个输入字段(插槽),并在值更新后发出一个事件
<template>
<v-container>
<slot name="field" :inputHandler="update"></slot>
</v-container>
</template>
<script>
export default {
props: {
currentValue: {
required: true
}
},
methods: {
update: function(newValue) {
this.$emit("updated", newValue);
}
}
};
</script>
Your consuming component would be 您的消耗组件是
<template>
<v-container>
<InputItem :currentValue="value" @updated="onUpdate">
<template v-slot:field="{ inputHandler }">
<v-text-field
:value="value"
@input="inputHandler"
></v-text-field>
</template>
</InputItem>
</v-container>
</template>
<script>
import InputItem from "../../components/InputItem";
export default {
components: {
InputItem
},
data: function() {
return {
value: "not empty"
};
},
methods: {
onUpdate: function(newValue) {
this.value = newValue;
}
}
};
</script>
The provided example HTML code uses Vuetify elements but I hope this is ok. 所提供的示例HTML代码使用Vuetify元素,但我希望可以。
