In this tutorial you will learn how to get page name from url in javascript. I have already written a post that teaches same thing and in asp.net. I will recommend you to get page name from url by using client side language such as javascript. Try to write as less server side code as possible because if same thing can be achieved through client side language javascript then there is no need to write server side code and put burden on server. Now let's have a look over how to do so

Get page name from url in javascript.

<script language="javascript">
        var url = window.location.pathname;

        var myPageName = url.substring(url.lastIndexOf('/') + 1);    

        alert(myPageName);
</script>

So this is the way to get page name from url in javascript.

In this tutorial you will learn how to create div element dynamically by using javascript. We will do this by utilizing the DOM features of javascript. Let's have a look over example given below

Create div element dynamically by using javascript

<html xmlns="http://www.w3.org/1999/xhtml">
<head>

<title>Create div element dynamically using javascript</title>

<style type="text/css">

.myDivClass
{
color: #999;

padding: 10px;

width: 250px;

height: 150px;

border: solid 1px #666;

}

</style>

<script type="text/javascript" language="javascript">

function CreateDivElement() {

var divElement = document.createElement("div");

divElement.id = "myDiv";

divElement.className = "myDivClass";

divElement.innerHTML = "Hello World!";
document.body.appendChild(divElement);

}

</script>

</head>

<body>

<div>

<input id="myBtn" type="button" value="Click Me" onclick="CreateDivElement();" />

</div>

</body>

</html>

And if you want to want to create div element inside any other html element of page body then nothing to worry. Let's suppose we have a div in our page which id is testDiv like given below
<div id="testDiv">
</div>
and you want to create div inside this testDiv. Just you have to change the last line of CreateDivElement() function from


document.body.appendChild(divElement);
to
document.getElementById('testDiv').appendChild(divElement);


and that's it. I hope you will like this tutorial.
