Question

我想要合并它们并使用ng-if，而不是两个单独的ng-switch。但是，img()函数未按预期切换。我该怎么办？

转过来：

<img ng-src="{{img(myColor)}}" ng-if="myColor">

<img ng-src="{{img(myColor2)}}" ng-if="myColor2">

进入这个：

<div ng-switch on = "myColor2">
    <div ng-switch-when = "myColor2">
        <img ng-src="{{img(myColor2)}}">
    </div>
    <div ng-switch-default = "myColor">
        <img ng-src="{{img(myColor)}}">
    </div>
</div>

Here's an example for ng-switch

You might be understanding it wrong.

ng-switch on = "myColor2" -- means you want to evaluate the value of the scope variable myColor2.

ng-switch-when = "myColor2" -- states that if the VALUE of myColor2 is equal to 'myColor2' then do this.

ng-switch-default -- should have no = value.
