Hello Folks,<br />
<br />
I've a website &amp;&nbsp;with an option to open window popup.<br />
I am able to open window popup &amp;&nbsp;restricted with same popup (<i><u>in case user click again to open window popup</u></i>) but once request post then again, new popup opens (if user clicks on that option).<br />
<br />
FYI, used <br />

<pre><code id="code-10-28959113-1">var newWindowpopup = null

checked for equal to null OR closed then open new window otherwise not</code></pre>
<br />
Do you have any thought to open same window popup (if already open) irrespective post to server? As you know, it should be browser compatibility. <br />
<br />
Best Regards

JavaScript: Restrict with only one window popup

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

ASP.NET

A scripting language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted (rather than compiled). Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs. Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.
