在这里我对使用自定义过滤器的清晰度数据网格有一点问题 我所做的一切都像所说的here,并且过滤器可以正常工作,但不正确
主要问题在于Datagrid项目集合中,当accepts方法为该项目返回 false 时,它并没有将其从datagrid项目集合中删除,并且当accepts方法返回 true 该项目只是在datagrid中复制
以下是示例:
Datagrid HTML:
<clr-datagrid class="custom-dg">
<clr-dg-column [clrDgField]="'transaction.date'"
[clrDgSortBy]="transactionDateComparator">
Date
<clr-dg-string-filter [clrDgStringFilter]="transactionDateFilter"></clr-dg-string-filter>
</clr-dg-column>
<clr-dg-column [clrDgField]="'transaction.state'"
[clrDgSortBy]="transactionStateComparator">
State
<clr-dg-filter>
<app-transaction-state-filter [transactions]="this.transactionsList"></app-transaction-state-filter>
</clr-dg-filter>
</clr-dg-column>
<clr-dg-column [clrDgField]="'transaction.sum'"
[clrDgSortBy]="transactionSumComparator">Sum</clr-dg-column>
<clr-dg-column [clrDgField]="'transaction.source'"
[clrDgSortBy]="transactionSourceComparator">Source</clr-dg-column>
<clr-dg-column [clrDgField]="'transaction.destination'"
[clrDgSortBy]="transactionDestinationComparator">Destination</clr-dg-column>
<clr-dg-column [clrDgField]="'transaction.comment'"
[clrDgSortBy]="transactionCommentComparator">Comment</clr-dg-column>
<clr-dg-row *clrDgItems="let transaction of this.transactionsList">
<clr-dg-cell>{{transaction.date}}</clr-dg-cell>
<clr-dg-cell>{{transaction.state}}</clr-dg-cell>
<clr-dg-cell>{{transaction.sum}}</clr-dg-cell>
<clr-dg-cell>{{transaction.source}}</clr-dg-cell>
<clr-dg-cell>{{transaction.destination}}</clr-dg-cell>
<clr-dg-cell>{{transaction.comment}}</clr-dg-cell>
</clr-dg-row>
<clr-dg-footer>
<clr-dg-pagination #pagination [clrDgPageSize]="10">
<clr-dg-page-size [clrPageSizeOptions]="[10,20,50,100]">Transactions per page</clr-dg-page-size>
{{pagination.firstItem + 1}} - {{pagination.lastItem + 1}}
of {{pagination.totalItems}} transactions
</clr-dg-pagination>
</clr-dg-footer>
</clr-datagrid>
过滤TS:
export class TransactionStateFilterComponent implements ClrDatagridFilterInterface<Transaction> {
private states: string[] = new Array();
@Input()
transactions: Transaction[];
constructor(private filterContainer: ClrDatagridFilter) {
filterContainer.setFilter(this);
}
accepts(transaction: Transaction) {
if (this.states.indexOf(transaction.state.toString()) > -1) {
return true;
} else {
return false;
}
}
changes = new Subject<any>();
isActive(): boolean {
return true;
}
onCheckedChange(param: string) {
if (this.states.indexOf(param) > -1) {
this.transactions = [];
for (var i = 0; i < this.states.length; i++) {
if (this.states[i] === param) {
this.states.splice(i, 1);
i--;
}
}
} else {
this.states.push(param);
}
this.changes.next();
}
}
文件管理器HTML:
<div>
<div>
<p><input type="checkbox" (change)="onCheckedChange('1')" />Failed</p>
</div>
<div>
<p><input type="checkbox" (change)="onCheckedChange('2')" />InProgress</p>
</div>
<div>
<p><input type="checkbox" (change)="onCheckedChange('3')" />Denied</p>
</div>
<div>
<p><input type="checkbox" (change)="onCheckedChange('4')" />Canceled</p>
</div>
<div>
<p><input type="checkbox" (change)="onCheckedChange('5')" />Successful</p>
</div>
</div>
谢谢您的帮助!

您可以尝试替换
this.states.splice(i, 1);
与
this.states = this.states.splice(i, 1);
使用您的onCheckedChange
方法
