I have the data of products, and I am filtering the data using a search value and then rendering the options using that filtered data. The products data is coming from the global redux store as a prop. For some reason, the dropdown shows data only when the search value is null, when I start typing, the filteredData
is updated and the component get re-rendered as well, but the options show no data.
I have checked whether the right filteredData
is used to map over the options. The options does not seem to render even when the component is re-rendered.
Please have a look at the code below :
import React from 'react';
// import {useState} from 'react';
import {Select} from 'antd';
import {connect} from 'react-redux';
import {fetchProductsAsync} from 'common/actions/fetchData';
const {Option} = Select;
class SelectOptions extends React.Component {
state = {
filteredData: [],
value: undefined,
};
componentDidMount() {
const {fetchProductsAsync} = this.props;
fetchProductsAsync();
const {products} = this.props;
this.setState({filteredData: products || []});
}
componentDidUpdate() {
console.log(this.state.filteredData);
}
filterData = (value) => {
const {products} = this.props;
const filData = products.filter((prod) => {
return prod.name.includes(value);
});
// console.log(filData);
this.setState({filteredData: filData});
};
handleSearch = (value) => {
const {products} = this.props;
if (value) {
// this.setState({value});
this.filterData(value);
// console.log('yes');
} else {
console.log('empty');
this.setState({filteredData: products});
this.forceUpdate();
}
};
handleChange = (value) => {
// console.log(value);
this.setState({value});
};
render() {
const {others} = this.props;
// console.log(this.state.filteredData);
const options = this.state.filteredData.map((item, index) => {
console.log(item);
return (
<Option value={item.value || item[others.key] || item}>
{others.customTitle ? (
<text style={{fontSize: 13, fontWeight: 'bold'}}>{item[others.customTitle]}</text>
) : (
item.label || item[others.key] || item
)}
{others.dataKeys ? (
<div className="row" style={{flexWrap: 'wrap'}}>
{others.dataKeys.map((i) => (
<text style={{fontSize: 11, marginLeft: 5, marginRight: 5}}>{item[i]}</text>
))}
</div>
) : null}
</Option>
);
});
return (
<Select
showSearch
onSearch={this.handleSearch}
// placeholder="Select"
// key={this.state.filteredData.length}
value={this.state.value}
onChange={this.handleChange}>
{options}
</Select>
);
}
}
const mapStateToProps = (state) => {
return {products: state.data.products || []};
};
export default connect(mapStateToProps, {fetchProductsAsync})(SelectOptions);
Try setting this prop on the Select component filterOption={false}
