关于h5传参给安卓（JSBridge）

Question

<button id="privew" type="button" onclick="JSBridge.previewImage(JSON.stringify({'current':'1', 'urls':['https://t7.baidu.com/it/u=1595072465,3644073269&fm=193&f=GIF',
                                                        'https://t7.baidu.com/it/u=4198287529,2774471735&fm=193&f=GIF', 'https://t7.baidu.com/it/u=3435942975,1552946865&fm=193&f=GIF',
                                                        'https://t7.baidu.com/it/u=1956604245,3662848045&fm=193&f=GIF']}))">
    图片预览
</button>

这样写是没问题的，现在需求就是想把JSBridge.previewImage()括号中的东西全放出去，比如下面这种

<button id="privew" type="button" onclick="JSBridge.previewImage(handlePreview)">图片预览</button>
//js  不知道下面这个怎么写
function handlePreview(){

}

//安卓端这样接收

public void previewImage(String dataJson)

Answer 1

<button id="privew" type="button" onclick="handlePreview">图片预览</button>
function handlePreview(){
  JSBridge.previewImage(JSON.stringify({'current':'1', 'urls':['https://t7.baidu.com/it/u=1595072465,3644073269&fm=193&f=GIF',
                                                        'https://t7.baidu.com/it/u=4198287529,2774471735&fm=193&f=GIF', 'https://t7.baidu.com/it/u=3435942975,1552946865&fm=193&f=GIF',
                                                        'https://t7.baidu.com/it/u=1956604245,3662848045&fm=193&f=GIF']}))
}
