Question

What is the best way to set up my page to detect the "enter" key input when the form is not created with the <form> tag?

Within the HTML code, data is received and stored in variables within my TypeScript file. At the end of the HTML, there is a button that was created separately from any user input containers. This button triggers a function that processes the information it receives. I confirmed that the button works independently, even without user input, although it will not output anything in such cases. Initially, I believed that implementing an "enter" event would not be an issue. However, despite numerous attempts, it still does not work as expected.

I have experimented with adding ng-keypress to the top div class and also tried placing it within the button tag. I have not attempted using a directive because I am unsure where to include it, and suggestions online indicate that ng-keypress should suffice.

<button class="btn btn-primary float-left" (click)="submitSearch()">Search</button>

 </div>

<button class="btn btn-primary float-left" (click)="submitSearch()"ng-keypress= "submitSearch()">Search</button>
 </div>

Despite including ng-keypress in the second line, nothing appears on the console upon pressing keys as anticipated.

Answer №1

In my opinion, one of the simplest and most direct methods to accomplish this would be:

<div (keydown.Enter)="submitSearch()">

This way, all form fields within your main container element (in this instance, the div) will respond to the keydown event.

consider using the keydown event instead.

<input 
    type="text"
    (click)="performSearch()"
    (keydown)="performSearch()"
/>

To achieve this functionality, you can create a custom directive and apply it to the parent div or form element:

app.directive('ngEnter', function () {
    return function (scope, element, attrs) {
        element.bind("keydown keypress", function (event) {
            if (event.which === 13) {
                scope.$apply(function () {
                    scope.$eval(attrs.ngEnter);
                });
                event.preventDefault();
            }
        });
    };
});

Incorporate the directive into your HTML structure like so:

<div ng-enter="submitSearch()">
    <input type="text" />
    ...
</div>
<button type="submit" (click)="submitSearch()">Submit</button>
