Your website is only usable for users with JavaScript enabled. A User is able to view the source, however, it isn’t understandable. It involves taking your code, using a custom made function to “encrypt” it somehow, and then putting it in an HTML file along with a function that will decrypt it for the browser. This is by far the most popular way to try to hide one’s source code. As pointless and silly as this method is, there are some still who use it. However, must all people will notice the scroll bars and will scroll around to find your code. It involves adding a ton of white space before the start of your code so that the view source menu appears blank. HTML CSS and JavaScript are client-side languages so the browser need to be able to find the source code easily and then interpret them so you can see your website.Ĭheck out the following suggestions regarding Obfuscation and related facts for other possibilities: 1.Disable right Click for the page.īy disabling the right click you can prevent to a limit for copy the content from the website Server-side rendering of your code via PHP or other server-side language may help to remove from view sensitive code.

Also make sure the button text changes from "Show clock" to "Hide clock" as appropriate. Test your web page, and make sure you can show and hide the clock with the new button. While you're switching the clock's display back and forth from "block" to "none", you're also changing the text (innerHTML) on the clock button, so that alternates between "Show clock" and "Hide clock", depending on the current display state of the clock. If the clock is already hidden, you change the display to "block" to make it visible again. If the display is currently set to "block", the clock is visible, so you change the display to "none", which hides the clock. In this new toggleClock() function, your are using JavaScript to retrieve the clock element, get the current value of its display style, then checking it. now toggle the clock and the button text, depending on current state Var clockButton = document.getElementById('clockButton') also get the clock button, so we can change what it says get the current value of the clock's display property Var m圜lock = document.getElementById('clock') Here's that function - just add it to the existing script section in the head of your web page: Now that you have a button that, when clicked, calls the toggleClock() function, you need to create a toggleClock() function. That's so you can access it easily using JavaScript (you'll see why in a moment). Note that this button is essentially the same as the one you created in Lesson 1 to show the alert.
