I am using AngularJS.
I need to create a simple form to upload a file to the server. I want to disable my form submits button if the user has not selected any file from the input type file.
And enable the button if the user selects a file.
I am trying to use AngularJS form validation by making the input field required. But my button is not re-enabling for some reason.
I checked ng-model is also not updating its state. Anyone can please help me find the issue in my code?
code -
<form name="uploadForm">
<div class="row">
<div class="col-12">
<div class="form-group">
<label class="control-label col-form-label">Select File <span style="color: red">*</span>
</label>
<div class="input-group">
<div class="input-group-prepend">
<span class="input-group-text">Upload</span>
</div>
<div class="custom-file">
<input type="file" name="fileinput" class="custom-file-input" id="inputGroupFile01" ng-model="file" required>
<label class="custom-file-label" for="inputGroupFile01">Choose file</label>
</div>
</div>
</div>
</div>
<div class="col-12">
<div class="form-group">
<label class="control-label col-form-label">Click on Upload to upload the file</label>
<button class="btn btn-primary" ng-click="upload()" ng-disabled="uploadForm.$invalid">Upload</button>
</div>
</div>
</div>
</form>
