jQuery allows the developers to create a sliding effect on elements, with the help of the following slide methods:
- slideDown()
- slideUp()
- slideToggle()
The slideDown() method is used to slide down the selected elements.
Example:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#flip").click(function(){
$("#panel").slideDown();
});
});
</script>
<style>
#panel, #flip {padding: 2px;text-align: center;background-color: yellow;border: solid 5px red;}
#panel {
padding: 50px;
display: none;
}
</style>
</head>
<body>
<div id="flip">Click me. There is a message for you. </div>
<div id="panel">HELLO! NICE TO SEE YOU.</div>
</body>
</html>
The slideDown() method can also include some other parameters to add more animation to the sliding effect.
Syntax:
$(selector).slideDown(speed, callback);
Speed:
- Speed is an optional parameter that specifies the speed of the delay in sliding down the selected elements.
- It can accept string values: “slow”, “fast”, or in milliseconds.
- The default speed is 400 milliseconds.
- On using “slow” keyword as the value for the speed parameter, the compiler takes it as 600 milliseconds.
- Similarly, on using “fast” keyword as the value for the speed parameter, the compiler takes it as 200 milliseconds.
Callback:
- Callback is also an optional parameter.
- Callback is the function to be executed once the slideDown() method’s execution is complete.
Example:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#flip").click(function(){
$("#panel").slideDown(5000);
});
});
</script>
<style>
#panel, #flip {
padding: 4px; text-align: center; background-color: pink; border: solid 3px blue;
}
#panel {
padding: 50px; display: none;
}
</style>
</head>
<body>
<div id="flip">Click me. There is a message for you. </div>
<div id="panel">HELLO! NICE TO SEE YOU.</div>
</body>
</html>
