After the javascript window is opened, how to set it so that only other pages in the window can be operated and cannot be moved?

In the process of web application development, JavaScript is often used to open a new window. However, sometimes we hope that the user can only operate the newly opened window and not perform any operations on the original page. How to set it up in this case?

The following are some implementation methods for reference:

Method 1: Add parameters when using JavaScript to open a window

The first method is to use JavaScript to open a new window by Add parameters for control. The specific implementation method is as follows:

window.open(url,name,'height=500,width=500,top=100,left=100,toolbar=no,menubar=no,scrollbars=no, resizable=no,location=no, status=no')

In this code, we use the window.open method to open a new window, where name is the window name, url is the address of the new window. Among other parameters, toolbar=no, menubar=no, scrollbars=no, resizable=no, location= no, status=no means hiding the toolbar, menu bar, scroll bar, size adjustment button, address bar and status bar respectively.

In this way, the user can only see the content of the current page in the new window, and other operations are disabled.

Method 2: Disable other pages through JavaScript code

The second method is to add JavaScript code to disable other pages in the newly opened window. This method requires adding the following code to the newly opened page:

window.opener.location.href='javascript:;';

The function of this code is to change the address of the original page to javascript:;, so that the user clicks on the original page None of the links are operational.

In addition, you can also add the following code so that after opening a new window, the user cannot return to the original page when clicking the browser back button:

history.forward();

Method 3: Disable other pages by setting events

The third method is to add an event so that the system automatically disables the operation of the original page when switching to a newly opened window. The specific implementation is as follows:

var newpage = window.open("http://www.example.com");
newpage.onfocus = function () {
    window.blur();
    setTimeout(function () { window.focus(); }, 100);
};

In this code, we use the window.open method to open a new window and save it in the variable newpage. And newpage.onfocus refers to the event that is automatically executed when the user switches back to the new window. We disable the original page through the window.blur() method, and then refocus the window after 100 milliseconds.

Summary

The above is the method to control the newly opened window to only operate this window, but not the original web page. Different methods have different advantages and disadvantages. When using them, you can choose the appropriate method according to actual needs.
