How to use target in location.href
提问by user1084509
I am currently developing a web application where I need to open a popup window to show a report. The problem is that some versions of explorer don't support the window.open javascript function, so when this is the case I catch the error and open the new url with location.href. Here the code:
我目前正在开发一个 Web 应用程序，我需要在其中打开一个弹出窗口来显示报告。问题是某些版本的资源管理器不支持 window.open javascript 函数，因此在这种情况下，我会捕获错误并使用 location.href 打开新 url。这里的代码：
try {
window.open(url, "","width=1002,height=700,location=0,menubar=0,scrollbars=1,status=1,resizable=0")
} catch(e) {
location.target = "_blank";
location.href = url;
}
The problem is that the location.target is not working and I would like to know if there is a way to specify the target of the location.href so it can be opened in a new tab.
问题是 location.target 不起作用，我想知道是否有办法指定 location.href 的目标，以便可以在新选项卡中打开它。

Say what? Can you provide a reference for that statement? With respect, I think you must be mistaken. This workson IE6 and IE9, for instance.
说什么？您能否提供该声明的参考？恕我直言，我想你一定是误会了。例如，这适用于 IE6 和 IE9。
Most modern browsers won't let your code use window.openexcept in direct response to a user event, in order to keep spam pop-ups and such at bay; perhaps that's what you're thinking of. As long as you only use window.openwhen responding to a user event, you should be fine using window.open — with all versions of IE.
大多数现代浏览器不会让您的代码使用window.open除非直接响应用户事件，以防止垃圾邮件弹出窗口等；也许这就是你的想法。只要你只window.open在响应用户事件时使用，你应该可以使用window.open - 所有版本的 IE。
There is no way to use locationto open a new window. Just window.openor, of course, the user clicking a link with target="_blank".
没有办法用来location打开一个新窗口。只是window.open或者，当然，用户单击带有 的链接target="_blank"。

try this one, which simulates a click on an anchor.
试试这个，它模拟点击一个锚点。
var a = document.createElement('a');
a.href='http://www.google.com';
a.target = '_blank';
document.body.appendChild(a);
a.click();

You can use this on any element where onclick works:
您可以在 onclick 工作的任何元素上使用它：
onclick="window.open('some.htm','_blank');"
onclick="window.open('some.htm','_blank');"

You could try this:
你可以试试这个：
<script type="text/javascript">
function newWindow(url){
window.open(url);
}
</script>
And call the function
并调用函数

If you go with the solution by @qiao, perhaps you would want to remove the appended child since the tab remains open and subsequent clicks would add more elements to the DOM.
如果您采用@qiao 的解决方案，也许您想删除附加的子项，因为该选项卡保持打开状态，后续单击会向 DOM 添加更多元素。
// Code by @qiao
var a = document.createElement('a')
a.href = 'http://www.google.com'
a.target = '_blank'
document.body.appendChild(a)
a.click()
// Added code
document.body.removeChild(a)
Maybe someone could post a comment to his post, because I cannot.
也许有人可以对他的帖子发表评论，因为我不能。

If you are using an <a/>to trigger the report, you can try this approach. Instead of attempting to spawn a new window when window.open()fails, make the default scenario to open a new window via target(and prevent it if window.open()succeeds).
如果您正在使用 an<a/>来触发报告，您可以尝试这种方法。不要在window.open()失败时尝试生成新窗口，而是将默认场景设置为通过打开新窗口target（并在window.open()成功时阻止它）。

Why not have a hidden anchor tag on the page with the target set as you need, then simulate clicking it when you need the pop out?
为什么不在页面上设置一个隐藏的锚标签，并根据需要设置目标，然后在需要弹出时模拟单击它？
How can I simulate a click to an anchor tag?
This would work in the cases where the window.open did not work
这将在 window.open 不起作用的情况下起作用

As of 2014, you can trigger the click on a <a/>tag. However, for security reasons, you have to do it in a clickevent handler, or the browser will tag it as a popup (some other events may allow you to safely trigger the opening).
从 2014 年开始，您可以触发对<a/>标签的点击。但是，出于安全原因，您必须在click事件处理程序中执行此操作，否则浏览器会将其标记为弹出窗口（某些其他事件可能允许您安全地触发打开）。

<a href="url" target="_blank"> <input type="button" value="fake button" /> </a>
