facing issue while restrict number and special characters in angularjs

Question

I want to restrict the special characters and space in the input text field. I used the

ng-pattern="/^(?=.*[0-9])(?=.*[a-zA-Z])([a-zA-Z0-9]+)$/"

to restrict the special characters. but its not working. How can i achieve that?

here is my html code:

<form name="JobDescriptionForm" id="JobDescriptionForm" class="form-horizontal" role="form" novalidate>
    <div class="col-md-12 col-sm-12 col-lg-12 nopadding select-job">
        <label for="createJob" class="col-md-12 col-sm-12 col-lg-12 nopadding"> Create Job </label>
        <input type="text" ng-model="price" name="price_field" ng-pattern="/^(?=.*[0-9])(?=.*[a-zA-Z])([a-zA-Z0-9]+)$/" required>
        <span ng-show="JobDescriptionForm.price_field.$error.pattern">Not a valid number!</span>
    </div>
</form>

I' m referring this code because I'm little confused for is there any need to write something in Controller? What to do in this case?

And check your code as well, your end tag for "form" has a typo, you wrote "
