H5的上传图片如何实现呢?
以下是我用vue实现的图片上传功能,仅供参考。

html, body { width: 100%; height: 100%; font-family: "微软雅黑"; background: #F8F8F8 !important; } #box { width: 100%; position: relative; height: 100%; } .pingjiaContent { width: 100%; border-radius: 0.1rem; /* border: 1px solid #CACACA; */ padding: 0.2rem; box-sizing: border-box; outline: none; margin-bottom: 0; border: none; resize: none; } .uploadBox { width: 2rem; height: 2rem; position: relative; margin-right: 0.15rem; margin-bottom: 0.35rem; } .uploadImg { width: 100%; height: 100%; overflow: hidden; } .closeImg { width: 0.5rem; height: 0.5rem; position: absolute; top: 2%; right: 1%; } .inputButton { width: 2rem; height: 2rem; display: flex; flex-direction: column; align-items: center; justify-content: center; border: 1px solid #cdcdcd; position: relative; margin-right: 0.15rem; margin-bottom: 0.35rem; } .addImg { width: 1.2rem; height: 1.2rem; } .upload { width: 100%; height: 100%; opacity: 0; position: absolute; top: 0; left: 0; z-index: 100; } .imgBox { width: 100%; background: #fff; display: flex; align-items: center; flex-wrap: wrap; padding-bottom: 0.5rem; box-sizing: border-box; padding: 0.5rem; } .submitTask { background: #EF504D; width: 100%; height: 0.8rem; color: #fff; font-size: 0.32rem; line-height: 0.8rem; text-align: center; border-radius: 0.1rem; margin-top: 0.8rem; } .back { background: #F7F7F7; width: 100%; height: 0.8rem; color: #4D4D4D; font-size: 0.32rem; line-height: 0.8rem; text-align: center; border-radius: 0.1rem; margin-top: 0.4rem; border: 1px solid #E0E0E0; }
后台PHP只需要利用 获取到接收的文件即可实现上传。
