AngularJS: The 'myInputName' property is not defined and cannot be read

Encountering an error with AngularJS:

https://i.sstatic.net/TBHem.png

The issue is related to the titleInput TextBox name property:

@Html.TextBox("titleInput", null, new { @placeholder = @T("Message title"), @class = "form-control", ng_model = "feed.feedData().title", ng_required = "true" })

The error seems to be originating from the FeedValidationService method:

public titleInputValidation(messageForm: any, isTitleInputValid: boolean): boolean {
    if (messageForm.titleInput.$valid) {
        isTitleInputValid = true;
    }
    else {
        isTitleInputValid = false;
    }

    return isTitleInputValid;
}

All functionalities are working fine except for this browser error. Any suggestions on how to resolve this?

Answer №1

If you're looking for a solution, consider verifying the existence of messageForm.
For example: 

if (messageForm && messageForm .titleInput.$valid)
or 

if (messageForm !== undefined) { 
    // Add your code here 
}
