如何限制链接在新标签页中只打开一次? [英] How to limit the link open only once in new tab?
问题描述
在我的代码中,单击链接后,我在新选项卡中打开一个 pdf 文件,但是如果该文件已打开,则在第二次单击后,而不是在新选项卡中打开,我想重定向到该文件的打开选项卡.
In my code, after click on a link I'm open a pdf file in new tab, But after second click if that file is already open then instead of open in new tab I want to redirect to open tab of that file.
我的代码:
<span style="margin-left:10%;"><a href="image/Eng_Pamphlet.pdf" target="_blank">Broucher</a></span>'
如上面的选项卡所示,我设置了目标属性_blank",因此它始终在新选项卡中打开链接.但我想在第一次之后重定向到第一个打开的标签.
As shown in above tab I'm set the target attribute "_blank", So it opens the link always in new tab. But I want after first time it redirect to first open tab only.
推荐答案
改用 target="_new"
.这将在同一选项卡中打开链接
Use target="_new"
instead. This will open the link in the same tab
_new
并不是真正做到这一点的最佳方式,正如 Chankey 在下面的评论中所指出的那样.您可以为 target
属性创建一个自定义"值,该值将允许链接仅在特定选项卡中打开.
_new
is not really the best way to do this, as noted in the comment below by Chankey. You can just create a 'custom' value for the target
attribute that will allow the link to only open in a specific tab.
