angular.js - angular's-if

Question

How to set multiple conditions in ng-if? For example, ng-if="code == 2 ‖ 3" is it possible?

Answer 1

......
This has nothing to do with angular, let's take a look at javascript first.

code === 2 || code === 3

Answer 2

ng-if is followed by a normal js statement. If your intention is to compare whether code is equal to 2||3, then write o like this. k
If your intention is to determine whether code is equal to 2 or equal to 3, that is

code === 2 || code === 3

Of course, the code must first be in the scope of angular.

Answer 3

{true:THIS, false:THAT}[CONDITION]
<p ng-repeater="item in items">

<p>{{item.description}}</p>
<p>{{ {true:'available', false:'oh no, you don't have it'}[isExists(item)] }}</p>

</p>

方法二:
<p ng-repeater="item in items">

    <p>{{item.description}}</p>
    <p ng-switch on="isExists(item)">
        <span ng-switch-when="true">Available</span>
        <span ng-switch-default>oh no, you don't have it</span>
    </p>
</p>

方法三:
<p ng-repeater="item in items">
    <p>{{item.description}}</p>
    <p ng-show="isExists(item)">available</p>
    <p ng-show="!isExists(item)">oh no, you don't have it</p>
</p>
