],item: {type: 1,url: 'adfdsfadsfasdf.png',
},

// utils/index.js/*** 图片/视频预览* @param list* @param item*/
export function previewImg(list, item) {const i = list.findIndex(e => e.url === item.url)state.$state.previewData = {list: list.filter(item => item.type * 1 === 1 || item.type * 1 === 2),active: i !== -1 ? i : 0,}// 如果只有图片和视频，就不需要这个判断了// 这个判断是type=3的时候是一个网址，点击后要跳转或打开新页面if (item.type * 1 === 3) {// window.location.href = item.url// window.location.href = valshowLoadingToast({message: '加载中...',forbidClick: true,})// 判断当前url 是否是有效的链接// 通过正则判断// const reg = /^(((ht|f)tps?):\/\/)?([^!@#$%^&*?.\s-]([^!@#$%^&*?.\s]{0,63}[^!@#$%^&*?.\s])?\.)+[a-z]{2,6}\/?/const reg = /^(http|https):\/\/([\w.]+\/?)\S*/if (reg.test(item.url)) {// alert('正确链接')// 如果是则跳转window.location.href = item.url} else {// alert('错误链接')// 否则跳转404页面uni.navigateTo({url: `/pages/404?url=${item.url}`,})}} else {uni.navigateTo({url: '/pages/previewMedia',})}
}
