我现在正在建立一个基于drupal的电子商务网站,并陷入困境。总体而言,它仍然是新的反应和编码方式,但仍在尝试学习。因此,使用redux和rest api获取了所有数据,并获得了我的产品,版本和属性。产品页面基于URL设置特定产品,现在我需要能够通过下拉菜单选择其他属性。目前,我有一个占位符下拉列表,该下拉列表与react-bootstrap文档中显示的匹配。但是,我需要根据保存属性的数组在该下拉菜单中放置选项。
我敢肯定这很简单,但是我一直在搜索,但是还没有找到可行的答案。希望你们能提供帮助。
在浏览代码时,请记住,sizes [[]是我要从中放置数据的数组,作为下拉菜单中的可选选项。
这是产品页面:
import React, { Component} from 'react';
import '../../css/Home.css';
import MenuBar from "../sub-components/MenuBar";
import LeftMenuBar from "../sub-components/LeftMenuBar";
import "../../css/ProductPage.css"
import WomensWear from "../../media/WomensWear.jpg"
import {
Dropdown,
DropdownToggle,
DropdownMenu,
DropdownItem } from 'reactstrap';
class ProductPage extends Component {
constructor(props) {
super(props);
this.toggle = this.toggle.bind(this);
this.state = {
dropdownOpen: false
};
}
toggle() {
this.setState(prevState => ({
dropdownOpen: !prevState.dropdownOpen
}));
}
getProduct() {
let product = null;
let sizes = [];
if (this.props.products && this.props.products.items.length) {
product = this.props.products.items.find(o => o.path[0].alias === this.props.router.match.url);
if (product && this.props.variations && this.props.attributes) {
product.something = [];
for (let i = 0; i < product.variations.length; i++) {
let varid = product.variations[i].target_id;
let variation = this.props.variations.items.find(o => o.variation_id[0].value === varid);
variation.size = this.props.attributes.items.find(o => o.attribute_value_id[0].value === variation.attribute_size[0].target_id);
sizes.push({value: variation.size.attribute_value_id[0].value, name: variation.size.name[0].value});
product.something.push(variation);
console.log(sizes);
}
}
}
return product;
}
render() {
let style = {
height: this.props.height - 56,
};
let product = this.getProduct();
let body = product && product.body.length ? product.body[0].value : null;
return (
<div className="App" id="default">

答案 0 :(得分:3)
React的整洁之处在于您可以使用常规JS。
<Dropdown isOpen={this.state.dropdownOpen} toggle={this.toggle}>
<DropdownToggle caret id="size-dropdown">
Size
</DropdownToggle>
<DropdownMenu>
{sizes.map(size => (
<DropdownItem>{size}</DropdownItem>
))}
</DropdownMenu>
</Dropdown>
旁注:select
似乎是更合适的元素,但这不是您的问题。
