JQuery prepend() and prependTo() Example

May 13, 2014 by Krishna Srinivasan Leave a Comment

JQuery Prepend() Method

JQuery prepend() method is used to insert content to the beginning of each element inside matching of HTML elements. It inserts specified content as the first child of each element in the jQuery collection. With prepend() method, the selector expression preceding the method is the container into which the content is inserted. This method is similar to append() method, but only difference is that append() method inserts content to the end of selected elements.

JQuery Prepend() Syntax

[code lang=”xml”]
$(selector).prepend(content);
[/code]

It contains parameter called content which specifies content to be inserted at the beginning of each element in the set of matched elements.

JQuery Prepend() Example

[code lang=”xml”]
<!doctype html>
<head>
<title>JQuery Prepend Method</title>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
</head>
<h2>JQuery Prepend Method Example</h2>
<script type="text/javascript">
$(document).ready(function(){
$("button").click(function(){
$(".myprepend").prepend("<strong>Div element is prepended…</strong>");
});
});
</script>
<body>
<button>Click to see prepend elements</button>
<div class="myprepend" style="color:red">
<p>Hello World!!!</p>
</div>
</body>
</html>
[/code]

As shown in the above program, we have used the code inside $(document).ready which is an event which fires up when document is ready. It will run once the page document object model is ready for JavaScript code to execute.
$(“button”).click(function()) line defines click event which occurs when button is clicked.
$(“.myprepend”).prepend(“Div element is prepended…“); statement indicates JS interpreter to prepend the content in quotes to div class elements.
When you run the script, click on the button which will appear on the browser, the line Div element is prepended… prepends before the line Hello World!!!.

Run This Demo

When you run the above example, you would get the following output:

JQuery PrependTo() Method

The prependTo() method also do the same task as prepend() method does. It inserts content to the beginning of the specified elements. The prepend() method precedes the content and with the prependTo() method, the content precedes the method as selector expression and inserted into the target container. The major difference between both methods is in the syntax, specifically in the placement of the content and target.

JQuery PrependTo() Syntax

[code lang=”xml”]
$(content).prependTo(selector);
[/code]

It contains parameter called selector which specifies on which elements to prepend the content to, in the set of matched elements.

JQuery PrependTo() Example

[code lang=”xml”]
<!doctype html>
<head>
<title>JQuery PrependTo Method</title>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
</head>
<h2>JQuery PrependTo Method Example</h2>
<script type="text/javascript">
$(document).ready(function(){
$("button").click(function(){
$("<strong>Div element is prepended…</strong>").prependTo(".myprepend");
});
});
</script>
<body>
<button>Click to see prepend elements</button>
<div class="myprepend" style="color:red">
</div>
<p>Hello World!!!</p>
</body>
</html>
[/code]

As shown in the above program, we have used the code inside $(document).ready which is an event which fires up when document is ready. It will run once the page document object model is ready for JavaScript code to execute.
$(“button”).click(function()) line defines click event which occurs when button is clicked.
$(“Div element is prepended…“).prependTo(“.myprepend”); statement indicates JS interpreter to prepend the content in quotes to div class elements.
When you run the script, click on the button which will appear on the browser, the line Div element is prepended… prepends before the line Hello World!!!.

JQuery : Difference Between detach(), hide() And remove() Methods

May 6, 2014 by Krishna Srinivasan Leave a Comment

This tutorial explains the difference between the three methods detach, remove and hide used in the JQuery programming with simple examples. If you have any questions, please write it in the comments section.

JQuery Detach() Method

JQuery detach() method helps in removing the selected elements including all text and child nodes from the DOM. This method is same as remove method except it will keep all data and events associated with the removed elements even after it is removed from the DOM(Document Object Model). It stores all the data associated with the element and is used to reinsert the elements data and event handlers.

JQuery Detach() Syntax

[code lang=”xml”]
$(selector).detach();
[/code]

It does not contain any parameters.

JQuery Detach() Example

[code lang=”xml”]
<!doctype html>
<head>
<title>JQuery Detach Method</title>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
</head>
<h2>JQuery Detach Method Example</h2>
<script type="text/javascript">
$(document).ready(function(){
$("button").click(function(){
$("h3,h4").detach();
});
});
</script>
<body>
<button>Click to remove elements</button>
<h3>Hello World!!!!!!!</h3>
<h4>Welcome to JQuery!!!</h4>
</body>
</html>
[/code]

As shown in the above program, we have used the code inside $(document).ready which is an event which fires up when document is ready. It will run once the page document object model is ready for JavaScript code to execute.
$(“button”).click(function()) line defines click event which occurs when button is clicked.
$(“h3,h4”).detach(); line defines the detach() method which removes all the elements from the DOM.
When we run the above script, a button will appear on the browser. If we click on the button, all elements will get removed from the DOM.

When you run the above example, you would get the following output:

JQuery Remove() Method

The remove() method is same as detach() method which removes the selected elements including all text and child nodes from the DOM. But it won’t keep all data and events associated with removed elements in the set of matched elements from the DOM completely. It restores elements data , not its event handlers. All events and data associated with elements are removed.

JQuery Remove() Syntax

[code lang=”xml”]
$(selector).remove();
[/code]

It does not contain any parameters.

JQuery Remove() Example

[code lang=”xml”]
<!doctype html>
<head>
<title>JQuery Remove Method</title>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
</head>
<h2>JQuery Remove Method Example</h2>
<script type="text/javascript">
$(document).ready(function(){
$("button").click(function(){
$("h3,h4").remove();
});
});
</script>
<body>
<button>Click to remove the elements</button>
<h3>Hello world!!!</h3>
<h4>Welcome to JQuery!!!</h4>
</body>
</html>
[/code]

As shown in the above program, we have used the code inside $(document).ready which is an event which fires up when document is ready. It will run once the page document object model is ready for JavaScript code to execute.
$(“button”).click(function()) line defines the click event which occurs when button is clicked.
$(“h3,h4”).remove(); line defines the remove() method which removes the selected elements from the DOM.
When we run the above script, a button will appear on the browser. If we click on the button, all elements will get removed from the DOM.

When you run the above example, you would get the following output:

JQuery Hide() Method

The hide() method is used to hide elements from the DOM completely. The elements will be hidden immediately with no animation. The elements will not display once user hides the elements in the DOM. This is equivalent to calling CSS display property to none. i.e. .css(‘display’, ‘none’).

JQuery Hide() Syntax

[code lang=”xml”]
$(selector).hide(speed, callback);
[/code]

It has parameters called speed which specifies speed of the hiding effect and can take possible vales such as slow, fast and callback is a function which is to be executed after the hide() method completes.

JQuery Hide() Example

[code lang=”xml”]
<!DOCTYPE html>
<html>
<head>
<title>JQuery Hide Method</title>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
</head>
<h2>JQuery Hide Method Example</h2>
<script type="text/javascript">
$(document).ready(function() {
$("button").click(function() {
$("button").hide("fast",function(){
$("#message").text("The button is hidden now!!!");
});
});
});
</script>
<body>
<p id="message"></p>
<button>After clicking on this button, it will get hidden.</button>
</body>
</html>
[/code]

As shown in the above program, we have used the code inside $(document).ready which is an event which fires up when document is ready. It will run once the page document object model is ready for JavaScript code to execute.
$(“button”).click(function()) line defines the click event which occurs when button is clicked.
$(“button”).hide(“fast”,function()) line defines the hide() method which is going to hide elements from the DOM completely. It takes value called fast which defines speed of the hiding effect and defines a function which is to be executed after the hide() method completes.
When we run above script, a button will appear. After clicking on the button, it will be hidden from the DOM and specified message will get display after button is hidden.

When you run the above example, you would get the following output:

Differences Between Detach(), Remove() and Hide() Methods

Detach()	Remove()	Hide()
It helps in removing the selected elements including all text and child nodes from the DOM.	It also removes set of matched elements including all text and child nodes from the DOM.	It hides elements from the DOM completely.
It keeps all data and events associated with selected elements.	It won’t keep all data and events associated with selected elements.	The matched elements will be hidden immediately with no animation.
It reinsert the elements data and event handlers.	It restores elements data, not its event handlers.	It will not display the elements once it hides the elements in the DOM.

JQuery after() And insertAfter() Example

After() Method

JQuery After method is used for inserting content after each element in the set of matched elements. In general, it is used to insert things after one or several elements. With after() method, the selector expression preceding the method is the container after which the content is inserted.

JQuery After() Syntax

[code lang=”xml”]
$(selector).after(content)
[/code]
