Having trouble with the disabled property in Angular 10? Learn how to properly use it and troubleshoot

---Update---

I had previously posted this question without receiving a solution. I came across a Github blog that mentioned the "isButtonDisabled" alone may not work and a function needs to be called instead. In my TypeScript code, I can only generate a boolean value after validating certain conditions. What could possibly be going wrong?

Check out the GitHub link for reference

I have experimented with both [disabled] and disabled attributes but they do not seem to align with my TypeScript condition. I have four buttons that need to be enabled or disabled based on my TypeScript logic involving seven different conditions. Presently, the button gets disabled regardless of the condition. Can anyone suggest an alternative approach to address this issue?

HTML

<button type="button" [disabled]="isButtonDisabled"
              style="background: #79CEA4 !important;color: #FFFFFF !important;font-size: 13px;font-weight: 600;margin-right: 20px"
              class="btn btn-lg" (click)="finish()">FINISH</button>

TS

isButtonDisabled: boolean;
for (var EmployeeList of Employee){
        if (EmployeeList.EmployeeStatus == 'Active') {
          this.isButtonDisabled = false;
          return 'circle3';  
        }
        else if (EmployeeList.EmployeeStatus == 'Inactive') {
           this.isButtonDisabled = true;
           return 'circle1';

}

Answer №1

The issue lies in the way standard HTML handles the <button> element with the attribute disabled="anything", which is interpreted as being disabled.

To work around this in Angular, you can toggle the presence of the attribute by using the following approach:

<button [attr.disabled]="isButtonDisabled ? true: null"...
