I can't find any obvious way to make a new page open in a real popup, not a tab in a different window. Certainly that is not an option in the Lectora Action. The course window still ends up behind the LMS window after closing the popup. However, this doesn't have any visible effect. I did try adding JavaScript to the popup window that on closing, switches focus to its parent: only instead, he/she is left looking at the LMS, and the course is behind that and it may not be obvious how to proceed, if the student isn't highly computer-literate. Now, the user closes that window to return to the course. However, when the child window, the Lectora course, opens a new window, that content ends up in a tab in the parent (LMS) window. The thing is, almost any LMS opens a course in a child of its own window. Here's the problem: in Chrome 43 and 44, it opens the page in the parent of the course window, not a totally new window. In the below example, we have added the left and top attributes to the window.open() method and give proper values to make the popup window center.So, Lectora (16) has an Action, Display Page in Popup window, which opens a page from the current course in a new window. Screen.height − It returns the screen height in the pixels. Screen.width − It returns the screen width in the pixels. Top − It sets the starting top position of the popup window. Left − It sets starting left position of the window. In the above method, we have added two new parameters Var newWindow = window.open( url, 'center window', Var top = ( screen.height -height_of_popup_window ) / 2 set thevertical center of the popup window the center of the screen. Var left = ( screen.width– width_of_popup_window ) / 2 Stainless steel rock guards and a solar window guard also keep the trailer looking. set the horizontal center of the popup window the center of the screen. Pack up and go anywhere you please, with nothing holding you back. Users can follow the below syntax to the window.open() method to add left and top attributes into that.

We will set the left and top positions for the popup window, which will make it appear in the center. By default, a popup window appears at the top left corner of the screen. popup window in that i have created 4 dropdowns and one ok button, if i willl click on that ok button the values should pass to parent window dropd. Now, we will set the attributes in such a way so that users can see the popup window at the center of the screen. We have learned the basic things about the popup window. In the above output, when users click on the button, it will open the popup window in the top left corner. In the openPopUp() function, we have implemented the window.open() method, which opens the home page of the TutorialsPoint site in the new window. When the user clicks on the button, it will call a function named openPopUp(). In the below example, we have created the button. Scrollbars − It shows the scrollbar inside the popup window, if content inside the window is greater than the window size. Resizable − It allows to resize the popup window. Width − It sets the width for the popup window. Height − It sets the height for the popup window. URL − It is the URL of the webpage, which will be opened in the popup window of the browser. newWindow = window.open(url, 'popUpWindow', 'height=' + height + ', width=' + width + ', resizable=yes, scrollbars=yes, toolbar=yes') Users can follow the below syntax to use the window.open() method. Also, we will learn to set the attributes for the window.open() method to make it better. In this section, we will create a sample popup window to get familiar with the how window.open() method works. Also, we can change the position of the popup window to look it better.

In this situation, developers use the window.open() method to open the new browser window.Īlso, we can style the popup window and set the height and width. Programmers often need to open a new popup window to show another webpage without redirecting the user to the other webpage.

In this tutorial, we will learn to center a popup window on the screen using JavaScript.
