我试图在用户单击angular 7应用程序中的复选框时显示加载div。我正在尝试使用一个名为ShowLoader的布尔标志,但是如果在事件中将其设置为true,则加载div确实会显示并且不会消失。如果将标志设置为false,则加载div永远不会显示。我该如何控制这种行为
屏幕截图
HTML
<div>
<input type="checkbox" id="chk" style="width: 13px; height: 13px;" checked="checked"
(click)="isInvestedSelected($event)" />
<label for="chkInvested">Invested</label>
</div>
<div class="card scrollClass">
<div class="card-header panel-heading">
<span class="left-label" style="font-size: 18px; font-weight: bold; ">Legal Fund Classes</span>
<div class="pull-right" style="padding-right:10px; display: inline-block; vertical-align:middle">
<button style="text-align: center; vertical-align:middle; margin-left: 10px"
class="btn btn-default pull-right" (click)="openCloneModal()"> <i data-bind="visible: true"
class="fa fa-copy"></i> Clone</button>
<button style="text-align: center; vertical-align:middle" class="btn btn-default pull-right"
(click)="openLegalFundClassModal()"> <i data-bind="visible: true" class="fa fa-plus-square"></i> Add Class</button>
</div>
</div>
The value of showloader is {{ShowLoader}}
<div *ngIf="!LegalFundClasses || !LegalFundClasses.AllTerms || !LegalFundClasses.LegalFundClassColumnNames || ShowLoader" style="padding-top:10px">
<div class="alert alert-warning" style="text-align:center" role="alert">
Loading... Please Wait
</div>
</div>
<div *ngIf="LegalFundClasses && LegalFundClasses.AllTerms && LegalFundClasses.LegalFundClassColumnNames">
<table class="fundClassesTable table-striped">
<tr *ngFor="let c of LegalFundClasses.LegalFundClassColumnNames">
<ng-container>
</ng-container>
</tr>
</div>
</div>
组件
public get ShowLoader(): boolean {
return this._showLoader;
}
public set ShowLoader(value: boolean) {
this._showLoader = value;
}
isInvestedSelected(s) {
this.ShowLoader = true;
this.LegalFundInvestedDetailsEvent.emit(s.target.checked);
this.termsStateService.IsInvested = s.target.checked;
}

@Tom尝试在组件中进行以下更改:
现在在 isInvestedSelected 方法中切换ShowLoader值
ShowLoader: boolean = false;
isInvestedSelected(s) {
this.ShowLoader = !this.ShowLoader;
..........
..........
}
