I need to conceal the
<span ng-show="currencyObject.to != 'undefined'">=</span>currencyObject.to has a value of undefined. This should only occur until the user selects an option from the dropdown menu. I attempted to use ng-show="currencyObject.to != 'undefined'"span, but it is not functioning as expected. The issue I am encountering is that upon initially loading the page, the = sign remains visible. <div class="row" ng-controller="QConvertController">
<div class="col-md-8 col-md-offset-2">
<div class="form-group">
<label for="amount">Amount</label>
<input type="number" step="any" class="form-control" id="amount" ng-model="currencyObject.amount">
</div>
</div>
<div class="col-md-8 col-md-offset-2">
<div class="form-group">
<label for="from">From</label>
<select class="form-control" id="from" ng-model="currencyObject.from" ng-change="getconvertedrate()">
<option ng-repeat="currencyCode in currencyCodes" value="{{currencyCode.value}}">{{currencyCode.display}}</option>
</select>
