下面的 Material 表取自example ，如何在添加新行时使“ahiddenfield”出现？我不太确定当即将添加新行时(在 onRowAdd 之前)如何访问状态。是否可以不用太头疼？
constructor(props) {
super(props);
this.state = {
columns: [
{ title: 'Name', field: 'name' },
{ title: 'Hidden Field', field: 'hiddenfield', hidden: true }
],
data: [
{ name: 'Mehmet' },
{ name: 'Zerya Betül'},
]
}
}
render() {
return (
<MaterialTable
title="Editable Preview"
columns={this.state.columns}
data={this.state.data}
editable={{
onRowAdd: newData =>
new Promise((resolve, reject) => {
setTimeout(() => {
{
const data = this.state.data;
data.push(newData);
this.setState({ data }, () => resolve());
}
resolve()
}, 1000)
}),
onRowUpdate: (newData, oldData) =>
new Promise((resolve, reject) => {
setTimeout(() => {
{
const data = this.state.data;
const index = data.indexOf(oldData);
data[index] = newData;
this.setState({ data }, () => resolve());
}
resolve()
}, 1000)
}),
onRowDelete: oldData =>
new Promise((resolve, reject) => {
setTimeout(() => {
{
let data = this.state.data;
const index = data.indexOf(oldData);
data.splice(index, 1);
this.setState({ data }, () => resolve());
}
resolve()
}, 1000)
}),
}}
/>
)
}
} ```
最佳答案
在您的 <MaterialTable /> 中组件，您应该替换 data像这样的 Prop :
data={Array.from(this.state.data)} .
文档中没有记录这一点。更多信息请点击:https://github.com/mbrn/material-table/issues/1900
