Topic: Change input icon color for validation

Vin free asked 5 years ago


Is is possible to change the color of the icon based on a attribute on the input tag ?

When you have an input with an icon, i'd be nice to have an attribute to make the icon go with the same color as the validation.

You can use the rules from ngIf directivie in ngClass, for example:

html:

<form>
  <div class="md-form">
    <mdb-icon fas icon="envelope" class="prefix" [ngClass]="{'icon-invalid' : input.invalid && (input.dirty || input.touched)}"></mdb-icon>
    <input mdbInput mdbValidate name="input" type="text" id="form1" class="form-control" name="test" [(ngModel)]="required" #input="ngModel" required>
    <label for="form1">Required validator</label>
    <mdb-error *ngIf="input.invalid && (input.dirty || input.touched)">Input invalid</mdb-error>
    <mdb-success *ngIf="input.valid && (input.dirty || input.touched)">Input valid</mdb-success>
  </div>
</form>

css:

.icon-invalid i {
    color: red;
}
