我正在尝试按// GoogleMapComponent.jsx
import React, { Component } from 'react'
export default class GoogleMap extends Component {
shouldComponentUpdate() {
return false;
}
componentDidMount() {
this.map = new google.maps.Map( this.refs.map, {
center: {lat: this.props.lat, lng: this.props.lng},
zoom: 5
})
}
componentWillReceiveProps(nextProps) {
this.map.panTo({ lat: nextPros.lat, lng: nextPros.lng });
}
render() {
return (
<div id="googleMap" ref="map" />
)
}
}
// App.jsx
import GoogleMap from './GoogleMapComponent'
import React, { Component } from 'react'
export default class App extends Component {
constructor(props) {
super(props);
this.state = {lat: 30.397, lng: 130.876};
}
render() {
return (
<div style={{ height: '100%'}} >
<button onClick={() => this.seState({ lat:50.712, lng: -30.08 }) }>
Your Favourite Place
</button>
<GoogleMap
lat={this.state.lat}
lng={this.state.lng}
/>
</div>
)
}
}
将文件名和国家/地区分开，并希望按年份将剩余文件移动到存档文件夹，但只能过滤年份而不是国家/地区名称
代码：
LastWriteTime输出为
Mode LastWriteTime Length Name ---- ------------- ------ ---- -a--- 6/25/2018 12:08 AM 31744 abc Italy_2016_2 - Copy - Copy.xls -a--- 6/25/2018 12:07 AM 31744 abc Italy_2016_2 - Copy.xls -a--- 6/25/2018 12:06 AM 31744 abc China_2017_1.xls -a--- 6/25/2018 12:07 AM 31744 abc NL_2017_2.xls -a--- 6/25/2018 12:05 AM 31744 abc Finland_2017_3.xls
在上面的数据中，第2行将被归档，因为意大利在2016年的最后写入时间是12:08。
我正在尝试通过$sourcedir = 'C:\Users\garang\Documents\input_files\Advisory_rate'
$destdir = 'C:\Users\garang\Documents\input_files\Advisory_rate\Archive'
Get-ChildItem -File -Path $sourcedir |
Where-Object BaseName -match '_(20\d{2})_\d' |
Group-Object $Matches[1] |
ForEach-Object {
$_.Group | Sort-Object LastWriteTime -Descending |
Select-Object -Skip 1 |
Move-Item -Destination $destdir -Force
}
拆分名称，但无法在上述条件下使用
Group-Object {$_.Basename.Split(' ')[2]}我认为问题出在组对象$ Matches [1] | ...如果删除此查询没有给出错误...我是否必须定义此$ matches
also tried:Where-Object BaseName -match ' ([a-z]+_20\d{2})_\d' | & Where-Object BaseName -match '_(20\d{2})_\d' |
$sourcedir = 'C:\Users\garang\Documents\input_files\Advisory_rate'
$destdir = 'C:\Users\garang\Documents\input_files\Advisory_rate\Archive'
Get-ChildItem -File -Path $sourcedir |
Where-Object BaseName -match ' ([a-z]+_20\d{2})_\d' |
Group-Object $Matches[1] |
ForEach-Object {
$_.Group | Sort-Object LastWriteTime -Descending |
Select-Object -Skip 1 |
Move-Item -Destination $destdir -Force
}
both conditions are tried separately gives the error message:
Cannot index into a null array.

尝试了新的正则表达式：

abc N Refund Maker_Japan_2017_Extra modified date:26/06 10:30
这就是预期的
好的...举一个新的例子...这些是四个文件...在这种情况下...需要按国家和年份分组...
文件将在那里，其他文件将移动该国家的档案
和年份...所以这里第二个和第三个文件将进入存档。...示例中，国家和年份的重复方式很简单，例如两次。和国家...
$sourcedir = 'C:\Users\garang\Documents\input_files\Advisory_rate'
$destdir = 'C:\Users\garang\Documents\input_files\Advisory_rate\Archive'
Get-ChildItem -File -Path $sourcedir |
Where-Object BaseName -match '_([a-z]+_20\d{2})_\d'|
Group-Object {$Matches[1]} |
ForEach-Object {
$_.Group | Sort-Object LastWriteTime -Descending |
Select-Object -Skip 1 |
Move-Item -Destination $destdir -Force
}
but file is not moving

i got new logic into it and getting output also how fix this in the query
$Match = "[^_]+_[0-9]{4}"
$Lines = get-clipboard
$Results = $Lines | %{$_ -Match $Match | %{$Matches[0]}}
output:
Japan_2017
Japan_2017
Italy_2017
Italy_2017
答案 0 :(得分：0)
对不起，我的错。您必须在组对象
中的$Matches[1]上加上花括号
$sourcedir = 'C:\Users\garang\Documents\input_files\Advisory_rate'
$destdir = 'C:\Users\garang\Documents\input_files\Advisory_rate\Archive'
Get-ChildItem -File -Path $sourcedir |
Where-Object BaseName -match ' ([a-z]+_20\d{2})_\d' |
Group-Object {$Matches[1]} |
ForEach-Object {
$_.Group | Sort-Object LastWriteTime -Descending |
Select-Object -Skip 1 |
Move-Item -Destination $destdir -Force
}
经过不同路径测试

和此脚本：

$sourcedir = 'C:\Users\garang\Documents\input_files\Advisory_rate'
$destdir = 'C:\Users\garang\Documents\input_files\Advisory_rate\Archive'
$sourcedir = 'A:\Test'
$destdir = 'A:\Test\Archive'
Get-ChildItem -File -Path $sourcedir |
Where-Object BaseName -match '_([a-z]+_20\d{2})_' |
Group-Object {$Matches[1]} |
ForEach-Object {
$_.Group | Sort-Object LastWriteTime -Descending |
Select-Object -Skip 1 |
Move-Item -Destination $destdir -Force
}
获取此输出：
