Allow window.open to open new window and not popup
提问by Emerson Maningo
I have this JS code:
我有这个JS代码：
window.open(loginurl, '_blank');
coming from a condition for example:
来自一个条件，例如：
if (userloggedin) {
//popup another page
} else {
window.open(loginurl, '_blank');
}
"loginurl" is an login URL that I would like to open in new window.
“loginurl”是我想在新窗口中打开的登录 URL。
Problem: This will be blocked in most browsers (Firefox and Chrome) because it behaves like a popup.
问题：这将在大多数浏览器（Firefox 和 Chrome）中被阻止，因为它的行为类似于弹出窗口。
I would like a solution that will still utilizes my login URL variable (not altering the if else statement), open it in new window without any warnings of a popup that is being blocked.
我想要一个仍然使用我的登录 URL 变量（不改变 if else 语句）的解决方案，在新窗口中打开它，而没有任何被阻止弹出窗口的警告。
I am searching for ways but I never found a solution. If somebody can provide some tips or insights. That would be highly appreciated.
我正在寻找方法，但我从未找到解决方案。如果有人可以提供一些提示或见解。这将不胜感激。
Thanks.
谢谢。

The window opened by window.openwill always be regarded as a pop-up to block by browsers when the function is triggered without a user action initiating it.
window.open当该功能被触发而没有用户操作启动它时，被打开的窗口将始终被视为一个弹出窗口以阻止浏览器。
That means that for example that these will not be blocked:
这意味着例如这些不会被阻止：
$('a').on('click.open', function(e) { e.preventDefault(); window.open('http://disney.com') });
Chrome even allows other events to trigger the popup, while firefox will not allow this:
Chrome 甚至允许其他事件触发弹出窗口，而 Firefox 不允许：
$(document).on('keydown', function(e) { window.open('http://stackexchange.com') });
And this will be blocked:
这将被阻止：
$(document).ready(function() { window.open('http://stackoverflow.com') });
So, unless you're triggering the window.openafter a user action, you can never be sure that your window won't be blocked.
因此，除非您在window.open用户操作之后触发，否则您永远无法确定您的窗口不会被阻止。

This way won't block your popup:
这种方式不会阻止您的弹出窗口：
$.ajax({
url:"url",
dataType: "text",
cache: false,
success: function(data){
window.open('url','_self');
}
});
