Using ng-non-bindable along with ng-if in Angular Google Maps allows for certain elements or

I recently came across an interesting discussion on the necessity of ng-non-bindable for the <ui-gmap-windows> element in Angular Google Maps. It shed some light on how ng-non-bindable is utilized in the directive.

However, I encountered an issue while attempting to utilize ng-if to selectively display certain icons in my marker infowindows. Unfortunately, ng-if doesn't cooperate well with ng-non-bindable, but removing it breaks the functionality of the info windows.

If anyone has a workaround to make ng-if function effectively in this scenario or offer an alternative solution, I would be greatly thankful.

      <ui-gmap-windows show="show">
            <div ng-non-bindable>{{obj.name}}<br>{{distance}} miles
            <span class="ion-man" ng-if="obj.men"></span>
          <span class="ion-woman" ng-if="obj.women"></span>
            <span class="ion-ios-people" ng-if="obj.people"></span>  
            </div>                     
          </div>
      </ui-gmap-windows>

Answer №1

To make use of the templateUrl and templateParameter attributes on the ui-gmap-windows directive, ensure that the templateUrl refers to the path of the .html template you wish to use, and the templateParameter contains the necessary parameters. You can view the code snippet below for reference. For more details, check out the documentation here.

<ui-gmap-windows  idKey="'name'" show="show" templateUrl="'pathToHtmltemplate.html'" templateParameter="'{name: 'name', distance: 1.3, womens_restroom: true}'">
</ui-gmap-windows>

In the html template, you can easily utilize ng-if without any issues.

Remember to refer to the object passed into templateParameter as a parameter in your html template. For example, the pathToHtmlTemplate.html file would look like this:

<div>
    {{parameter.name}}<br>{{parameter.distance}} miles
    <span ng-if="parameter.womens_restroom" class="ion-woman"></span>
</div>

The main reason for the lack of functionality is due to the fact that the priority of ng-if (600) is lower than that of ng-non-bindable (1000). Additionally, ng-non-bindable has the attribute terminal:true, causing ng-if to not compile because of the terminal nature of ng-non-bindable. One potential solution could be to use ng-switch (1200) directly on the element with ng-non-bindable, as it has a higher priority. However, this may not be suitable if there are multiple conditions that could be true.

Another approach is to create a custom directive, such as my-non-bindable, with a specified configuration of {priority:599, terminal:true}, and then use it in conjunction with ng-if like so:

.directive('gmapTemplate', function() {
return {
priority: 599,
terminal: true
};
});

Then, utilize it with ng-if.

<div gmap-template ng-if="someCond">{{obj.name}}<br>{{distance}} miles

If not, you may need to enclose non-bindable elements within an element with ng-if:

<div ng-if="someCond">
   <span ng-non-bindable>{{obj.name}}<br>{{distance}} miles</span>
</div>

angular.module('app', []).directive('gmapNonBindable', function() {
return {
priority: 599,
terminal: true
};
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular.min.js"></script>
<div ng-app="app" ng-init="test:123; show:false">
Show-->
  <input type="checkbox" ng-model="show" />
  <div gmap-Non-Bindable ng-if="show">{{test}}</div>
