How to put icon in placeholder in Angular Material?

Question

I'm trying to put icon in placeholder. I tried this code:

<md-input name="name">
   <md-placeholder>
      <i class="material-icons app-input-icon">face</i> Name
   </md-placeholder>
</md-input>

It was working (was showing icon with placeholder) before I reinstalled angular material and updated the angular cli. For this code browser is giving this error now: "'md-input' is not a known element".

then I tried this code:

 <md-input-container>
    <input mdInput placeholder="Name" name="name2">
 </md-input-container>

It is working properly but How can I put 'face' icon in its placeholder ?

Answer 1

Your problem was not the md-placeholder tag. Just like the error said, it was md-input which was deprecated. Angular Material recently changed his md-input tag into a mdInput directive.

But the md-placeholder is still working (not sure if it will last though).

The following code should work then :

<md-input-container>
    <md-placeholder>
        <md-icon>face</md-icon> Name
    </md-placeholder>
    <input mdInput name="name">
</md-input-container>

An alternative is to use the mdPrefix or mdSuffix directives to your md-icon tag. That will display your icon on the left or right of your input, but it won't follow the placeholder when you click on it.

Example :

<md-input-container>
    <md-icon mdPrefix>face</md-icon>
    <input mdInput placeholder="Name" name="name">
</md-input-container>

Angular 6

.example-full-width {
  width: 100%;
}
<mat-form-field  class="example-full-width">
 <mat-icon matPrefix>email</mat-icon>
  <input matInput
   type="email"
   tabindex="1"
   placeholder="Your Email"
   formControlName="email">
</mat-form-field>

Answer 3

mat-suffix didn't work for me either. Keeping up with their docs is always a chore, but as of 5.1.1 this should work:

<mat-form-field class="example-form-field">
  <input matInput type="text" placeholder="Clearable input" [(ngModel)]="value"/>
  <button mat-button *ngIf="value" matSuffix mat-icon-button aria-label="Clear" (click)="value=''">
    <mat-icon>close</mat-icon>
  </button>
</mat-form-field>
