How to set the address bar of JavaScript IE to read-only

JavaScript is a widely used web development language that is used to help us enhance the functionality and user experience of our website. In actual work, we often encounter situations where we need to set read-only in the browser address bar. This article explains how to use JavaScript to set the Internet Explorer address bar to read-only mode.

Internet Explorer is a browser software developed by Microsoft. It is one of the browsers that comes with the Windows operating system. Although its market share is no longer as good as other browsers such as Chrome and Firefox, it still has a certain number of users. group. Setting the address bar read-only in Internet Explorer requires the use of the DOM (Document Object Model) to manage the browser view and content.

Let’s implement the specific steps to set read-only mode in the Internet Explorer address bar:

1. Get the address bar object

Use window.location The object can obtain the browser's address information, including URL and hash value. We need to obtain the DOM object of the address bar through this object for subsequent operations.

var addressBar = document.getElementById("address");

2. Prohibit input

By setting the readOnly attribute of the address bar, the user can be prohibited from entering anything in the address bar. The syntax is:

addressBar.readOnly = true;

3. Hide the cursor

Although we have prohibited users from typing in the address bar, in some cases, the cursor may still appear in the address bar, which will cause trouble to users. Therefore, we need to hide the cursor after setting the read-only attribute. In Internet Explorer, we can hide the cursor by setting the contentEditable property of the address bar.

addressBar.contentEditable = false;

4. Disable pasting

If users are allowed to paste content from the clipboard into the address bar, there is no guarantee that the content in the address bar is verified. Therefore, we also need to disable users from pasting text in the address bar.

addressBar.onpaste = function() { return false; };

5. The final effect

Integrate the above steps, as shown below:

var addressBar = document.getElementById("address");
addressBar.readOnly = true;
addressBar.contentEditable = false;
addressBar.onpaste = function() { return false; };

The final effect is that the user cannot Enter, paste and select any text. This is a simple but practical technology that can help us better protect website security and user privacy.
