ng-app V/S data-ng-app in AngularJS
angularjs, angularjs-directive, bootstrapping
Solution
Both and are the same except for the fact that if you want your template/code to be according to be HTML compliant and follow the best practices. Use data-ng-app.
This is what the official documentation quotes:
"Best Practice: Prefer using the dash-delimited format (e.g. ng-bind for ngBind). If you want to use an HTML validating tool, you can instead use the data-prefixed version (e.g. data-ng-bind for ngBind). The other forms shown above are accepted for legacy reasons but we advise you to avoid them."
Hope that answers your question.
Cheers!
Problem
In AngularJS when using `ng-app`: `ng-app` found in the document will be used to define the root element to auto-bootstrap as an application. In some of the application it is being used as `data-ng-app`. Is there any difference in both of the following declaration, If Yes what & If No then which one is significant and why ? 1. ``` <body ng-app> <p>{{ 1 + 2 }}</p> </body> ``` 2. ``` <body data-ng-app> <p>{{ 1 + 2 }}</p> </body> ```
