Launch download in the same tab without opening new tab or window in Javascript
提问by Vervatovskis
I am using this javascript function to launch download
我正在使用这个 javascript 函数来启动下载
function startDownload(url) {
window.open(url, 'Download');
}
It works, but i want to block any new tab or new window launch, thanks.
它有效，但我想阻止任何新标签或新窗口启动，谢谢。

function startDownload(url) {
window.location.href = url;
}
This will start the download in the same page, exactly like when you click a link without any target other than _self.
这将在同一页面中开始下载，就像您单击一个没有任何目标的链接时一样_self。
To force the download of a file, make sure you send the right headers with it:
要强制下载文件，请确保随文件一起发送正确的标头：
Content-Disposition: attachment; filename="mypdf.pdf";
This will make sure that the file is not displayed in the browser instead of being downloaded. Replace the filename part with the filename you want as default on the save asdialog.
这将确保文件不会显示在浏览器中，而不是被下载。将文件名部分替换为save as对话框中您想要的默认文件名。

window.openwill open a new window \ tab (depending on user preferences) ... to just download the file use
window.open将打开一个新窗口\标签（取决于用户偏好）......只下载文件使用
window.location.href = url;
You can use this if the urlreturns a downloadable file rather than a web page
如果url返回可下载的文件而不是网页，您可以使用它
