html多图片下载方法1：＜a＞标签 涉及nginx
function download(filename, filetype) {
// 名字，后缀类型
if (filename == "") {
filename = "untitled";
}
if (filetype == "") {
filetype = "png";
}
var imgs = $(".test");
var totaladd = [];
for (var i = 0; i < imgs.length; i++) {
totaladd = $(imgs[i]).attr('src')
//将nginx上传请求地址替换为下载请求
totaladd = totaladd.replace('/profile', '/xiazai');
var link = document.createElement('a');
document.body.appendChild(link);
link.download = filename + i + "." + filetype;
link.href = totaladd;
// 创建一个单击事件
var event = new MouseEvent('click');
// 触发a的单击事件
link.dispatchEvent(event)
/!* setTimeout(() => {
// console.log("aaa")
link.click();
},300*i);*!/
// link.click();
// document.body.removeChild(link);
}
}
