Angular Circumstance

Can you help me out? I am trying to figure out how to create an IF...ELSE condition using AngularJS on my index.html file:

<ons-list-item modifier="chevron" class="list-item-container" ng-repeat="item in categories track by $index"> <a href="#/parts/{{ item.idold }}">
<ons-row>
<ons-col>
<div class="name">
{{ item.category }}  - {{ item.orgs }}
</div>
</ons-col>
<ons-col width="40px"></ons-col>
</ons-row></a>
</ons-list-item>

I need assistance with creating a condition where {{ item.orgs }} can be either 0 or 1. If {{ item.orgs }} equals 1, then I want the href attribute to be "#/parts/{{ item.idold }}", otherwise it should be "#/parts/detail/{{ item.id }}"

Answer №1

Have you considered implementing a function within your current scope to handle the logic you've outlined? You could then call this function within the {{ items.orgs }} section of your code to ensure correct output in your HTML.

Answer №2

In AngularJS expressions, you have the option to use the ?: conditional operators, which function similarly to those in other programming languages.

<a ng-href="#/parts/{{ item.orgs == 1 ? item.idold : item.id }}">

It's important to avoid injecting backward compatibility rules directly into your templates. As @WillsonMock pointed out, it is recommended to handle such logic in a separate controller or directive.

If the default value for item.idold is falsy, then you can simplify the expression by using the || OR logical operator instead of the ?: operator. JavaScript will automatically select the last truthy variable.

Here is a simplified version:

<a ng-href="#/parts/{{ item.idold || item.id }}">

Personally, I find the revised version easier to understand for some inexplicable reason.

Answer №3

Implement ng-if directive

<a ng-href="#/items/{{ product.idold }}" ng-if="product.orgs">{{ product.type }} </a>
<a ng-href="#/items/{{ product.id }}" ng-if="!product.orgs">{{ product.type }} </a>
