1. Overview
This document talks about prevent opening Oracle APEX application in multiple tabs with the same session state.
2. Technologies and Tools Used
The following technologies have been used to achieve this functionality,
- JavaScript
3. Use Case
The reason to avoid opening multiple tabs with the same session state is that there is a risk of incorrectly updating session states. As a result, incorrect data gets updated to the database.
4. Architecture
Here, we are just going to add simple JavaScript code in the global page of the application which will disable showing the Open New tab link on the right click of the mouse across the application.
Follow the steps to set the session state value using JS,
Step 1: Go to the global page of the application.
Step 2: Then create a dynamic action as below,
eg:
Name – Prevent opening application in multiple tabs
Event – Page Load
Action – Execute JavaScript Code
Code –
$(“body”).on(“click”, “a[datahref]”, function() {
var href = $(this).attr(“datahref”);
if (href) {
location.href = href;
}
});
$(document).mousedown(function(e) {
if (e.button == 2) {
$(‘a[href]’).each(function() {
var $t = $(this);
$t.attr({
datahref: $t.attr(‘href’)
})
.removeAttr(‘href’);
});
}
return true;
});
Step 3: Finally, save the changes and run the application.
