Assuming you are using bootstrap, you need to use the .input-group-button
class…
<div class="input-group">
<span class="input-group-addon" id="basic-addon1">www</span>
<input type="text" class="form-control" placeholder="Url" ng-model="currentUrl">
<span class="input-group-btn">
<input type="button" class="btn btn-primary" value="Go" ng-click="getUrl()">
</span>
</div>
