我正在尝试使用react-sortable-hoc的示例。可排序无法保持排序状态。看看GIF。react-sortable-hoc reactJS库排序问题
下面是我的示例代码..
import React, {Component} from 'react';
import {SortableContainer, SortableElement, arrayMove} from 'react-sortable-
hoc';
// Css
import './object_library.css'
const SortableItem = SortableElement(({value}) =>
<div className="Showcase_test_horizontalItem" >
<div>{value}</div>
<br />
<TestSortable />
</div>
);
const SortableList = SortableContainer(({items}) => {
return (
<div>
{items.map((value, index) => (
<SortableItem key={`item-${index}`} index={index} value={value}
/>
))}
</div>
);
});
class TestSortable extends Component {
constructor(props) {
super(props);
this.state = {
sum: 0
}
this.onAddChild = this.onAddChild.bind(this)
}
onAddChild() {
let prevSum = this.state.sum + 1;
this.setState({
sum: prevSum
});
}
render() {
return (
<div>
<div> {this.state.sum} </div>
<button className="my_plus_buttons" onClick={this.onAddChild}>+
</button>
</div>
);
}
}
class SortableComponent extends Component {
state = {
items: ['Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 5', 'Item 6'],
};
onSortEnd = ({oldIndex, newIndex}) => {
this.setState({
items: arrayMove(this.state.items, oldIndex, newIndex),
});
};
render() {
return <SortableList items={this.state.items} onSortEnd={this.onSortEnd}
axis="x"/>;
}
}
export default SortableComponent;
不知道为什么,这个库是不是保持状态?
感谢
感谢它的工作!我遗漏了SortableItem中的键 – HarshMakadia
