Opening a URL in a New Browser Tab with java script

General
1

Hi,
I need to open a New Browser Tab. I like to use a javascript function that I found here on xojo forum:

function open_in_new_tab(url )
{
  var win=window.open(url, '_blank');
  win.focus();
}

Where and how I can call from xojo this javascript function?

If you have a browser with locked popups this code will fail.

You should use: (put in the web app header)

function openInNewTab(url) { var win=window.open(url, '_blank') if (win) { win.focus } else { alert("Enable popups") } }

You could use a link object on the page (it works in any case) and by code set the visibility, the url and the text
You could use a webStyle (and extra information for style in the webApp header) to let the link object appear as a button

OK Antonio, thank you for quick response.

I tried with a link with a weblabel and I set the target to ‘New Window’: http://127.0.0.1:8080/?page=spec_day_WP

but in the new window it not open spec_day_WP but the startup page.

So I tried with a button and in the action event I wrote:

ExecuteJavaScript(“window.open(”“http://127.0.0.1:8080/?page=spec_day_WP”");")

Same problem!

Where I fail?

Thank you

Do you read the page parameter in session.open ?
You could use the tag (/#spec_day_wp) to handle this (both, if needed, in open and HashTagChanged)

There is no need to call JS, you could also use session.showUrl to create new web Page/Tab (but as your JS if can fail if pop up are blocked) the link will work always.

IN ANY CASE THE NEW WINDOW WILL BE A NEW SESSION NOT A NEW WINDOW ON THE SAME SESSION

Just a detail. When you post code, make sure to select it and click the code icon above the editor . It makes it way more legible.

ExecuteJavaScript("window.open(""http://127.0.0.1:8080/?page=spec_day_WP"");")

What kind of code are you using to parse the page parameter and display the corresponding page ?
