直接上代碼：
base64參數(shù)來源:
canvas.toDataURL("image/png");
function downloadFile(fileName, base64) {
const aLink = document.createElement('a');
const event = document.createEvent("MouseEvents");
event.initEvent('click', false, false); // initEvent 不加后兩個(gè)參數(shù)在FF下會(huì)報(bào)錯(cuò)
aLink.download = fileName;
aLink.href = base64;
aLink.dispatchEvent(event);
}
es6 export:
export default (fileName, base64) => {
const aLink = document.createElement('a');
const event = document.createEvent("MouseEvents");
event.initEvent('click', false, false); // initEvent 不加后兩個(gè)參數(shù)在FF下會(huì)報(bào)錯(cuò)
aLink.download = fileName;
aLink.href = base64;
aLink.dispatchEvent(event);
};
