If so, use the window’s name stored on the form. html, I added a text field (could be a hidden field), removed the closeMe() function since that was an epic fail! and modified the closeChild() function to look and see if the reference was lost. If we store that on the page, we can use it to get a reference again!īelow, in. You will notice I had a variable called “childname”. If the parent is refreshed, it loses the reference to the child and the parent cannot close the child. I hope this simple example has cleared a few thing up. #Close tab browser javascript windows#Scripts may not close windows that were not opened by script. Since the child window was opened with script, window.open() it can close itself.Since the parent was not opened with window.open() it cannot be closed using window.close() or self.close().Since we opened the child using a script, and had a reference handle to that child (in the variable “child”), by the MDN statement, we were able to close it using the handle to the window.close() ( child.close() ).A child window opens as separate window as a tab, just as before. Let btnClose = document.querySelector('#close') let btnOpen = document.querySelector('#open') In the event handler function of the close button, we are doing the same thing that we were doing in the anonymous function.If yes, then we are closing the newly created window by calling the close() method. In the anonymous function, we are checking whether myTab is defined or not using the if statement. We are using setTimeout() method with a delay of 3 seconds.We are storing the reference of the newly created window in the myTab variable.If you want to open a tab, then simply omit this third parameter since it is optional. Since we are providing a third parameter, it will no longer open a new tab, but a new window. In our case, we are specifying the height and width of the new window to be 500px.

If they close the entire browser, I will be able to log their out.I tried put everything in, event the web service, global file with sessionend, but seems like it does not react when closing tab. But the thing is users will not log out if they just close the tab on the browser. The third parameter takes a list of a comma-separated list of items with no white spaces in between. I already set the TimeOut Session like 15 mins. The second parameter specifies the target attribute or name of the window, we are passing “_blank” which means we want it to open in a new tab. The first parameter specifies a URL that we want to open. In the event handler function of the open button, we are calling the open() method and passing 3 parameters.We have attached a click event listener to both the button elements. We have a global variable myTab which is undefined initially.We have selected both the button elements using the document.querySelector() method and stored them in the btnOpen and btnClose variables respectively.
