Issue with manipulating element styles using jQuery in Angular2

My method of assigning IDs to elements dynamically using *ngFor looks like this:

<div *ngFor="let section of questionsBySubCat" class="col-md-12">
    <div class="subcat-container">
        <h4 class="sub-cat">{{ section?.subcategory }}</h4>
    </div>
    <div *ngFor="let question of section?.questions; let i = index" class="row">
        <div class="col-md-11 col-xs-10">
            <h5 (click)="toggleAnswer(question)" class="question">{{ question?.question }}</h5>
            <div class="answer-div" id="ques-{{question?.subcategory.split(' ').join('')}}-{{question?.num}}">
                <br> // DYNAMIC ID HERE ^^
                <p [innerHtml]="question?.answer" class="answer-text"></p>
                <hr>
                <br>
            </div>
        </div>
    </div>
</div>

Although the IDs are correctly created when inspecting the elements in the console, I am facing issues when trying to manipulate the elements using jQuery. Specifically, while logging out the inner HTML works fine, changing the element's CSS properties with jQuery (e.g. setting display to none) does not have any effect. I am puzzled as to why this might be happening.

Answer №1

For optimal performance, consider placing your jQuery code for modifying CSS elements within a setTimeOut() function.

If you are encountering issues with the code not working as intended, it may be because you are attempting to manipulate DOM elements before they are dynamically created. To avoid this issue, ensure that your jQuery code, which alters CSS properties of elements, is placed inside the setTimeOut() function.

 setTimeout(function () {
  $('your dynamic DOM element').addClass('in');
 }, 1000); 

I hope this explanation clarifies any confusion.
