• What's the difference/incompatibility between ng-model and ng-value? 5 answers

I was trying to give a value to textfield using ngvalue and textarea has that value but it when I submit it, it recognized as textarea is empty.

 <textarea  ng-value="main.record.basic_info.application_letter"
            class="form-control" 
            ng-model="main.record.apply_job.cover_letter" 
            name="name" rows="15" cols="80" style="resize: none">
 </textarea>

Answer 1

You cannot use these directives together

"It can also be used to achieve one-way binding of a given expression to an input element such as an input[text] or a textarea, when that element does not use ngModel."

You should set this value in your controller rather than use ng-value.

Answer 2

The documentation clearly states that ng-value should not be used when doing two-way binding with ng-model.

From the Docs:

ngValue

Binds the given expression to the value of the element.

It can also be used to achieve one-way binding of a given expression to an input element such as an input[text] or a textarea, when that element does not use ngModel.

— AngularJS ng-value Directive API Reference

Instead, initialize the value from the controller:

<textarea  ̶n̶g̶-̶v̶a̶l̶u̶e̶=̶"̶m̶a̶i̶n̶.̶r̶e̶c̶o̶r̶d̶.̶b̶a̶s̶i̶c̶_̶i̶n̶f̶o̶.̶a̶p̶p̶l̶i̶c̶a̶t̶i̶o̶n̶_̶l̶e̶t̶t̶e̶r̶"̶
           class="form-control" 
           ng-model="main.record.name" 
           name="name" rows="15" cols="80" style="resize: none">
</textarea>

$scope.main.record.name = $scope.main.record.basic_info.application_letter;
