小程序--判断显示不同图片的两种方式

1、src中

< image class= "audio" catchtap= 'onMusicTap' src= "{{isPlayingMusic? '/images/music/music-stop.png': '/images/music/music-start.png'}}"></ image >

2、if-else

< image catchtap= 'onCollectiontap' wx:if= "{{collected}}" src= '/images/icon/collection.png'></ image >

< image catchtap= 'onCollectiontap' wx:else src= '/images/icon/collection-anti.png'></ image >
