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. The hide() method simply sets the inline style display: none for the. If the clock is already hidden, you change the display to "block" to make it visible again. You can show and hide HTML elements using the jQuery show() and hide() methods. 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 This will hide the display element and show the hidden element. get the current value of the clock's display property We can combine the effects of show hide and use one effect toggle(). 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). Simply pass in a numeric value, and that value will be in milliseconds.Note that this button is essentially the same as the one you created in Lesson 1 to show the alert. If you'd rather be very specific, that is an option as well. If you want to specify the speed, you can simply pass in a string of either 'slow', 'normal', or 'fast'. ![]() You can pass a speed to the toggle() method which tells JQuery how long to show the element. By combining this method with toggle, we made it so clicking the same button can make the item that appears disappear when the button is clicked once again. What is jQuery Hide Show hide() method hides the selected HTML element by simply setting the inline style display: none for the selected elements. JQuery toggle() method is used to change the to display or hide HTML elements. Example 1 :- The hide() and show() functions in jQuery allow. ![]() Simply pass in a numeric value, and that value will be in milliseconds. Syntax 1:- Basic syntax (selector).hide() (selector). ![]() callback: Again, an optional parameter, which specifies the function to be executed after the hide () or show () method is completed. If you want to specify the speed, you can simply pass in a string of either 'slow', 'normal', or 'fast'. Syntax: (selector).show () (selector).show (speed,callback) (selector).hide () (selector).hide (speed,callback) speed: An optional parameter that specifies the speed of showing and hiding using the values: slow, fast or milliseconds. You can pass a speed to the hide() method which tells JQuery how long to show the element. Simply pass in a numeric value, and that value will be in milliseconds. The jQuery hide() method is used to hide the selected elements. You can pass a speed to the show() method which tells JQuery how long to show the element. • callback – optional function to be executed once the method’s execution is complete. To display or hide a
