我正在尝试将index.cshtml中的字符串传递给vue根元素。
我要传递的参数是:userId
查看:Index.cshtml(这是我获取参数的地方)
@using Microsoft.AspNetCore.Identity
@inject SignInManager<User> SignInManager
@using LaBouteilleDamour.Domain.Models;
@inject UserManager<User> UserManager
@if (SignInManager.IsSignedIn(User))
{
User user = await UserManager.GetUserAsync(User);
var userid = UserManager.GetUserId(User);
<div id="cartApp" userId:"userid"></div>
<script src="./js/Cart.bundle.js" asp-append-version="true"></script>
}
Vue根:Cart.boot.ts
import Vue from "vue";
import Cart from "./Components/Cart.vue";
new Vue({
el: "#cartApp",
template: '<Cart :userId="userId" />',
props: {
*userId: String,
},
components: {
Cart
}
});
Vue组件:Cart.vue(我需要在其中输入参数)
<template>
/*HTML*/
</template>
<script lang="ts">
import ShoppingCartItem from "../Components/ShoppingCartItem.vue";
import ShoppingCartService, { ICartItem } from "./AP
/ShoppingCartService";
import Vue from "vue";
interface IShoppingCartpageData {
items: ICartItem[],
}
export default Vue.extend({
data(): IShoppingCartpageData {
return {
items: [],
}
},
props: {
userId: {
type: String,
required:true,
}
},
...
})
</script>
答案 0 :(得分:0)
您正在模板中传递“ userId”,但是在vue的数据函数中未定义userId,因此它不是被动的,这意味着您不能在DOM中使用它,除非在数据函数中声明它。
另外,根视图不需要props,props应该只包含组件将从父组件接收的那些元素。
因此您的root元素代码必须看起来像这样
import Vue from "vue";
import Cart from "./Components/Cart.vue";
new Vue({
el: "#cartApp",
template: '<Cart :userId="userId" />',
data: function(){
return {
userId: userid, // Accessing userId from global scope as it is defined in Index.cshtml.
}
},
components: {
Cart
}
});
