An error occurred while trying to access the property "xxx" of an undefined object within the updateDirectives function

Experiencing an issue:

Encountering a 'Cannot read Property of Undefined Full_Name' error at Object.eval

<ion-item>
     <ion-label position="floating">Full Name</ion-label>
     <ion-input id="name" name=Full_Name #Full_Name="ngModel" [(ngModel)]="UpdateAddress.Full_Name"></ion-input>
</ion-item>

Snippet:

Answer №1

To tackle this issue, I suggest utilizing the Secure Navigation Technique (?):

UpdateAddress?.Full_Name

Your Revised Code:

<ion-item>
     <ion-label position="floating">Enter Full Name</ion-label>
     <ion-input id="name" name=Full_Name #Full_Name="ngModel" [(ngModel)]="UpdateAddress?.Full_Name"></ion-input>
</ion-item>

Answer №2

An Error Occurred: Unable to Access Property 'Full_Name'

The issue is with the following input field:

<ion-input id="name" name=Full_Name #Full_Name="ngModel"   [(ngModel)]="UpdateAddress.Full_Name"></ion-input>

This error occurs when UpdateAddress is not defined : https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/undefined

Solution

To resolve this issue, ensure that you initialize the UpdateAddress object in your model.
