I am currently familiarizing myself with the use of directives in AngularJS. I have a password.html file that contains an input field for passwords, and I have created a custom directive called 'passwordRequirement' to enforce specific requirements when users are creating their accounts. This is the code snippet from password.html:
<div class="form-group">
<label for="user_password">Password</label>
<input type="password" data-ng-change="passwordChanged();" data-ng-model="user.password" class="form-control" id="user_password" name="user_password"
placeholder="Password" required>
<div data-ng-show="enteredPassword">
<h4>For security reasons, the password must meet the following criteria</h4>
<password-requirement binding="passwordContainLowercase">Password must contain at least one lowercase character</password-requirement>
<br>
<password-requirement binding="passwordContainUpperCase">Password must contain at least one uppercase character</password-requirement>
<br>
<password-requirement binding="passwordLengthValid">Password length must be between 12 and 20 characters</password-requirement>
<br>
<password-requirement binding="passwordContainDigit">Password must contain at least one digit</password-requirement>
</div>
</div>
Each requirement is bound to a different property in the scope. In the directive definition, I have specified the variable "binding" in the scope.
Here is the code snippet for the directive definition:
app.directive('passwordRequirement',function()
{
return {
restrict: 'E',
scope:{binding:'@'},
templateUrl:'partials/content/common/passwordRequirement.html',
transclude:true
};
});
Next, I have the HTML template for the password requirement (which includes a label and a checkbox indicating whether the requirement has been met):
<div style="display:inline-block;">
<span data-ng-transclude></span>
<input type="checkbox" data-ng-disabled="true" data-ng-model="binding" data-ng-checked="binding">
{{binding}}
</div>
Although {{binding}} correctly displays the values of the bind property, inspecting the source code of the page reveals:
<input type="checkbox" data-ng-disabled="true" data-ng-model="binding" data-ng-checked="binding" class="ng-pristine ng-valid" disabled="disabled" checked="checked">
This indicates that the variable 'binding' is not being interpreted properly on the page. Why is this happening? I cannot use data-ng-model={{binding}}, so what is the solution to resolve this issue? Is it feasible in AngularJs? If so, what is the correct approach to achieving this? I initially believed my current method was correct, but it seems there may be an error.
Thank you in advance for your assistance.
