使用
基本使用同 antd Select,只是使用 SuperSelect 代替 Select
import SuperSelect from '@nuo-common/cloudjz-virtual-select';
const Option = SuperSelect.Option;
const Example = () => {
const children = [];
for (let i = 0; i < 100000; i++) {
children.push(
<Option value={i + ''} key={i}>
{i}
</Option>
);
}
return (
<SuperSelect
showSearch
// mode="multiple"
// onChange={onChange}
// onSearch={onSearch}
// onSelect={onSelect}
// optionHeight={50}
>
{children}
</SuperSelect>
);
};
Feature
- Support tens of thousands of data scrolling smoothly
- Same as ant api, easy to use
- Simple to implement, can be modified according to needs
- Support for direct use in antd Form
- set an
optionHeight
props to allow the height of the Option to be dynamically controlled
Code
- Use the antd Select dropdownRender method to customize the drop-down list content, rendering only about dozens of data in the viewport
- Calculate the scrolling distance of the list, re-render when scrolling about the height of the visible area, reduce the number of renderings and improve performance
- Represents methods such as antd Select onChange to implement the same api usage and callback parameter return
