vue前端實(shí)現(xiàn)前端下載,并實(shí)現(xiàn)點(diǎn)擊按鈕彈出本地窗口，選擇自定義保存路徑
一、實(shí)現(xiàn)下載
二、實(shí)現(xiàn)自定義保存路徑
直接上代碼，廢話不多說，點(diǎn)關(guān)注，不迷路
一、下載代碼文章來源：http://www.zghlxwxcb.cn/news/detail-641475.html

a.href = url;
a.dispatchEvent(event);
};
image.src = imgsrc;
}
function WriteToFile(sText) {
with (document) {
ir = createElement("iframe");
ir.id = "ifr";
ir.location = "about:blank";
ir.style.display = "none";
body.appendChild(ir);
with (getElementById("ifr").contentWindow.document) {
open();
write(sText);
close();
if (document.compatMode && document.all) {
execCommand("SaveAs", false, ".txt");
} else {
location = "data:application/rtf," + encodeURIComponent(sText);
}
}
setTimeout(function () {
body.removeChild(ir);
}, 1000);
}
}
function fn1() {
for (let i = 0; i < arr.length; i++) {
downloadIamge(arr[i]);
}
}

二、別找代碼了，不用代碼就可以實(shí)現(xiàn)
以下按照步驟一步一步來
按照紅色箭頭所指，用鼠標(biāo)戳它
