The toggle() Effect is a combination of slideUp and slideDown effect. i.e. Hides the visible element using slide up effect and if the element is hidden, makes it visible using slide down effect.
<html>
<head>
<title> My First Programme </title>
<script src = "https://ajax.googleapis.com/ajax/libs/jquery/3.7.1/jquery.min.js"> </script>
</head>
<body>
<h1> JQuery </h1>
<button> Show/Hide </button>
<p>
In a huge pond, <br/>
there lived many fish. <br/>
They were arrogant and <br/>
never listened to anyone.<br/>
</p>
<script>
$('button').click( function() {
$('p').slideToggle();
});
</script>
</body>
</html>
So, in the above example, we have a <p> element,
<p> In a huge pond, <br/> there lived many fish. <br/> They were arrogant and <br/> never listened to anyone.<br/> </p>
And a <button> element,
<button> Show/Hide </button>
And on buton click, the JQuery action gets triggered,
$('button').click( function() {
$('p').slideToggle();
});And the slideToggle() effect gets triggered. So if the <p> element is hidden, it shows it and it the <p> element is visible, it hides it.
Similarly, you can use the speed and callback function with toggle() effect.
