亲测可行，pc端使用时没有这个情况。在小程序端webview内会出现这个情况
mounted() {
//图片游览按返回键退出游览
this.$preview.on('imageLoadComplete', (e, item) = >{
let _preview = this.$preview.self;
let lookUrl = window.location.href + '&look';
window.history.pushState(null, null, lookUrl);
_preview.listen('close',
function() {
if (window.location.href.indexOf('&look') !== -1) {
window.history.back();
}
});
window.onhashchange = function() {
if (_preview !== null && _preview !== undefined) {
_preview.close();
_preview = null;
}
};
});
}
