我的任务是过滤一些数组并将其设置为FloatList。我用于过滤器的函数是:
updateInvoiceList = (text) => {
let invoiceList = [...this.state.baseInvoiceList];
invoiceList = invoiceList.filter(el => {
return el.name.toLowerCase().includes(text.toLowerCase())
});
this.setState({invoiceList})
}
之后,我将state.invoiceList提供给FlatList,并且一切正常-在设置某些文本最终列表时已正确过滤,当我删除输入值列表时返回。但!当我为样本“!”设置数组中不存在的某些符号时,函数清除所有数组,并且行为仍然正确。当我删除此“!”时我收到以下错误屏幕:
index=10 count=0

我该怎么办?
请改善您的功能。
updateInvoiceList = (text) => {
let invoiceList = [];
const { baseInvoiceList } = this.state;
if(text){
invoiceList = baseInvoiceList.filter(item => {
return item.name.toLowerCase().includes(text.toLowerCase());
});
}
this.setState({invoiceList});
}
