javascript - 对象取消订阅错误 : object unsubscribed

Question

ObjectUnsubscribedError: object unsubscribed，有时(不是每次)在文本框中输入任何值

---

HTML

<input #gb type="text" pInputText class="ui-widget ui-text"
[(ngModel)]="gb.value" (ngModelChange)="clearFilter(gb.value)" placeholder="Find" />

组件.ts

clearFilter(newValue) {
        this.infomessage = [];
        this.errormessage = [];
        this.isDelete = false;
        this.isDefaultLoad = false;
        if (this.oldFilterText === '' && newValue === '') {
            return false;
        }
        this.oldFilterText = newValue;
        if (this._configuration.isNullOrEmptyOrUndefined(newValue)) {
            this.sortField = '';
            if (!this._configuration.isNullOrEmptyOrUndefined(this.dataTable.sortField)) {
                this.sortField = this.dataTable.sortField;
            }
            this.dataTable.reset();
            this.tempFilteredRecords = [];
            this.getApprovalTypelist();
            this.dataTable.sortField = this.sortField;
            this.dataTable.sortMode = 'single';
            this.dataTable.sortOrder = this.sortOrder;
        }
    }

我的代码运行良好!但有时在文本框中键入时会出错。此外 clearFilter 在收到此错误后不会触发。

Answer 1

最后我得到了答案，我刚刚使用下面的代码取消订阅了 onFilter() 事件

this.dataTable.onFilter.unsubscribe();

感谢您的意见!
