在Reactjs中,如何为我的DataTable添加搜索过滤器?
                
             
            
            
                <p>我想通过在ReactJS中添加搜索过滤器来增强我的DataTable。我希望用户能够在表格中搜索特定的条目。目标是允许用户轻松搜索和查找表格中的特定数据。如何实现这个?</p>
<pre class="brush:php;toolbar:false;"><><ScrollView showsHorizontalScrollIndicator>
            <View style={styles.root}>
                <TouchableOpacity
                    style={[styles.button, styles.buttonOutline]}
                    onPress={handleBackButtonClick}
                >
                    <Text style={styles.buttonOutlineText}>返回</Text>
                </TouchableOpacity>
            </View>
            <TextInput
                style={styles.searchInput}
                placeholder="按客户搜索..."
            />
                    <DataTable style={styles.container}>
                            <DataTable.Header style={styles.tableHeader}>
                                <DataTable.Title>客户</DataTable.Title>
                                <DataTable.Title>地址</DataTable.Title>
                                <DataTable.Title>手机号码</DataTable.Title>
                                <DataTable.Title>车牌号码</DataTable.Title>
                            </DataTable.Header>
                            {displayedCustomers.map((customer, index) =>{
                                return(
                                <TouchableOpacity
                                    key={index}
                                    onPress={() => handleRowClick(customer)}
                                    style={[ styles.row,
                                        selectedRow && selectedRow.id === customer.id && styles.selectedRow]} 
                                >
                                <DataTable.Row key={index}>
                                    <DataTable.Cell>{customer.customer}</DataTable.Cell>
                                    <DataTable.Cell>{customer.address}</DataTable.Cell>
                                    <DataTable.Cell>{customer.mobileno}</DataTable.Cell>
                                    <DataTable.Cell>{customer.plateno}</DataTable.Cell>
                                </DataTable.Row>
                                </TouchableOpacity>
                                )
                                
                            })}
                        
                </DataTable>
                <DataTable.Pagination
                    page={currentPage}
                    numberOfPages={Math.ceil(customers.length / itemsPerPage)}
                    onPageChange={handlePageChange}
                />
            </ScrollView></pre>            
            
            
            
            
            
            
            
            
            
            
            
            
            
            
            
            
         
        
        
            
            
            
            
            
         
     
创建一个状态来保存搜索查询,并创建另一个状态来存储过滤后的数据:
const [searchQuery, setSearchQuery] = useState(''); const [filteredCustomers, setFilteredCustomers] = useState(customers); // 初始化为完整列表现在添加这个函数。首先更新
searchQuery状态,然后根据给定的text参数进行过滤,并将结果设置为filteredCustomers状态。const handleSearchInputChange = (text) => { setSearchQuery(text); const filtered = customers.filter( (customer) => customer.customer.toLowerCase().includes(text.toLowerCase()) || customer.address.toLowerCase().includes(text.toLowerCase()) || customer.mobileno.includes(text) || customer.plateno.includes(text) ); setFilteredCustomers(filtered); };每次在搜索
TextInput中输入时都要执行这个逻辑。<TextInput placeholder="按客户搜索..." onChangeText={handleSearchInputChange} value={searchQuery} />最后,只需通过
filtredCustomers而不是displayedCustomers进行映射:{filteredCustomers.map((customer, index) => { return ( <TouchableOpacity key={index} > // .... </TouchableOpacity> ) })
