I know that I can normally use myString.replace(/\*/g, '')
to remove *
from a string. But I cannot seem to make that work in a Angular HTML template. Here is what I doing...
<div class="panel panel--raised">
<div class="row">
<div class="form-group col-md-6">
<div class="form-group__text">
<input type="text" placeholder="Search... (min of 3 characters)" [(ngModel)]="searchString" minlength="3">
</div>
</div>
<div class="col-md-6">
<button class="btn btn--success btn--small host-info-button"
[disabled]="searchString.replace(/\*/g, '').length < 3"
(click)="getInfo(searchString)">Search</button>
</div>
</div>
</div>
Parser Error: Unexpected token /...
What am I doing wrong here?
Update:
What I am trying to do is make the user enter at least 3 characters that are not wildcard ( *
) characters. So a**
would only count as 1 character and ***
would count as zero characters, but *xyz*
would count as 3 characters. I am not sure that Validator.pattern()
would be able to accomplish this, but maybe I am just lacking imagination.
Unfortunately, RegExp literal is not supported by the templating language. They should be on your component.
More info on Angular Github repo issue: https://github.com/angular/angular/issues/21978
For this particular case, you can set up pattern validator and use something like this: Validators.pattern('/\*/g')
in template:
[disabled]="isDisabled"
in ts file:
get isDisabled(): boolean {
return this.searchString.replace(/\*/g, '').length < 3;
}
