Disabled not working

Question

1. Not working :
   • [disabled] = true ,
   • [disabled] = \"isDisabled\" -----ts > ( isDisabled=true)
   • basic html disabler al

Answer 1

When using attr.disabled, you have to supply the literal value, or omit the attribute altogether. Bear in mind that the disabled attribute in HTML disables an element that supports the attribute simply by being present.

<input [(ngModel)]="osoba.ime" [attr.disabled]="disabled?'':null" name="ime" type="text" id="ime">

Both of the following in HTML should result in an input being disabled...

<input disabled />
<input disabled="disabled" />

Answer 2

Use this :

 <input
    type="radio"
    id="primaryIPV6"
    value="2"
    [attr.disabled]="flagValue ? '' : null"
    formControlName="p_ip_type"
    (change)="optionalFn()">

Answer 3

In the reactive form creation, you can add as below

this.form= this.formBuilder.group({
      name: [{value: '', **disabled**: **true**}],
    });

the form value will be disbaled
