See this Plunkr :
Type text as "_______what___ever_____" (without quotes & _ represents spaces.)
Angular is removing spaces (from front & back & not in between) from the model (which is my desired behavior), but my textbox is keeping the spaces.
how can I remove the spaces from the textbox also ? i.e. I want the textbox also to reflect the value in model.
Edit: Better explanation of my needs.
For Eg: If I typed "___What_Ever____" ( without quote & _ is space),
1) my textbox will show me same what i have typed i.e. "___What_Ever____"
2) while my model will show me "What Ever".
I want my textbox's value also to be as "What Ever".

- I'm not sure it's a good idea to remove leading and trailing spaces as the user is typing. – camden_kid Commented Oct 17, 2016 at 9:12
- @camden_kid i am fine even if it happens on a blur or some other event. – Abdul Rehman Sayed Commented Oct 17, 2016 at 10:09

Reset to default 4Would this work? - Plunker
ng-blur doesn't work with your Plunker because the version of AngularJS you are loading (1.0.7) is quite old. I replaced it with the latest version (1.5.6). I also use ng-trim="false" to get the correct text input by the user.
Markup
<body ng-controller="MyCtrl">
<input type="text" ng-model="modelVal" ng-change="change()" ng-blur="blur()" ng-trim="false">
<br>
model value is "{{newModelVal}}"
</body>
JS
angular.module('app', [])
.controller('MyCtrl', function($scope) {
$scope.modelVal="";
$scope.change = function () {
$scope.newModelVal = $scope.modelVal;
}
$scope.blur = function () {
$scope.modelVal = $scope.newModelVal.trim();
}
})
You can do this,
<body ng-controller="MyCtrl">
<input type="text" ng-change="modelVal = modelVal.split(' ').join('')" ng-model="modelVal">
<br>
model value is "{{modelVal}}"
</body>
DEMO
EDIT:
You can use ngTrim which is provided by Angular itself
<input type="text" ng-trim="true" ng-model="modelVal">
<br> model value is "{{modelVal}}"
