JavaScript .focus() function not working in a text field

Question

I'm trying to use .focus() on the following form field without success. The tabindex of the div this element is in is 0.

<input class="form-control ng-pristine ng-valid ng-empty ng-touched" id="accessionNumber" type="text" name="filter.accessionNumber" ng-model="selectFields.accessionNumber" style="">

I'm using the following:

document.getElementsByName("filter.accessionNumber")[0].focus()

I've also tried document.getElementById using the "accessionNumber" ID as well as the .click() function instead of the .focus() function but none have worked so far

Thanks!

Short answer: Maybe have a look at this post

Longer answer: Since you are using Angular you should use the features of the framework that enable this: ViewChild

Steps to make it work:

1. In your component create a variable with the ViewChild annotation
2. Mark the element with the ViewChild id in the Components Template
3. Access your element in ngAfterViewInitlike

this.myElement.nativeElement.focus();
