angular的ng-if

Question

ng-if怎么设置多条件呢 比如 ng-if="code == 2 ‖ 3" 可以吗

Answer 1

.......
这个和 angular 无关，还是先看看 javascript 吧。

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

Answer 2

ng-if后面就是正常的js语句，如果你的意图就是比较code是否等于2||3，那这样写o。k
如果你的意图是判断code或者等于2，或者等于3，那就是

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

当然，code必须首先在angular的作用域里面。

Answer 3

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

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

</div>

方法二:
<div ng-repeater="item in items">

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

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