If else statement is not displaying the textbox properly

问题

I am comparing two conditions here and trying to display a textbox based on the condition.
如果两个日期匹配并且任务也相同,那么我需要根据数据库中已输入的内容显示文本框,如果没有输入,则需要显示一个空文本框。但它没有起作用。有人可以帮我吗?

<div *ngFor="let userTimesheet of timesheet">
    <div *ngIf="(((currentSun | date:'MM/dd/yyyy') === (userTimesheet?.task_date | date:'MM/dd/yyyy')) && (user.task.task_id == userTimesheet?.task)) else notMatching ">
        <input type="text" value="{{ userTimesheet.task_totaleffort}}" formControlName="sundaytime">
    </div>
    <ng-template #notMatching>
        <input type="text" value="" formControlName="sundaytime">
    </ng-template>
</div>

请注意,这是您提供的代码的翻译部分。

您可以直接在`input`的value属性中使用三元运算符:

&lt;div *ngFor=&quot;let userTimesheet of timesheet&quot;&gt;
    &lt;input 
        type=&quot;text&quot; 
        [value]=&quot;(((currentSun | date:&#39;MM/dd/yyyy&#39;) === (userTimesheet?.task_date | date:&#39;MM/dd/yyyy&#39;)) &amp;&amp; (user.task.task_id == userTimesheet?.task))) 
            ? userTimesheet.task_totaleffort : &#39;&#39;&quot; 
        formControlName=&quot;sundaytime&quot;&gt;
&lt;/div&gt;
英文:

You could directly use a ternary operator in the input value attribute :

&lt;div *ngFor=&quot;let userTimesheet of timesheet&quot;&gt;
    &lt;input 
        type=&quot;text&quot; 
        [value]=&quot;(((currentSun | date:&#39;MM/dd/yyyy&#39;) === (userTimesheet?.task_date | date:&#39;MM/dd/yyyy&#39;)) &amp;&amp; (user.task.task_id == userTimesheet?.task))) 
            ? userTimesheet.task_totaleffort : &#39;&#39;&quot; 
        formControlName=&quot;sundaytime&quot;&gt;
&lt;/div&gt;
