How to limit the link open only once in new tab?

Question

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.

My code:

<span style="margin-left:10%;"><a href="image/Eng_Pamphlet.pdf" target="_blank">Broucher</a></span>'

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.

Answer 1

Use target="_new" instead. This will open the link in the same tab

Edit:

_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.

Answer 2

just assign a custom name to your target tab, so all the links will be redirected to your custom tab

<span style="margin-left:10%;"><a href="image/Eng_Pamphlet.pdf" target="myPDFTabAndEveryTimeThisOne">Broucher</a></span>'

(if you use "_new" another standard "_new" link will overwrite your pdf tab).
