You can redirect your blog to another URL. This redirection can be done using JavaScript or by adding a special meta tag. This redirection is useful when you want to redirect your old blog users to your new blog. The function we use in JavaScript is window.location and the meta tag has http-equiv attribute.

So Let’s begin.

Go to Blogger -> Blog to be redirected -> Template -> Edit HTML.
You will get a box with a lot of text. Use one of the following methods to redirect :

If you have a user with a long name and want to short it because it won’t fit into the element that contains the name, you can either do it on the server or the client. In this post I am going to tell you how to accomplish this with PHP and JavaScript.
Suppose We have a user named Paul Steve Panakkal (my cousin). To separate the first name, middle name and last name you can do the following in PHP :

The Window.postMessage helps to make scripts talk over different domain connections. When you call a function on an external iframe from the parent window, Javascript won’t allow it.
That’s because of the Cross Domain Policy that makes this not possible. But it’s possible since Javascript introduced postMessage function.

Suppose you want to call a function on an cross domain iframe with id monu. Let the function be subins(). Here’s how to do it using postMessage technic.

While loading an iframe on page the most difficult thing is to set it’s height to the height of the content of the iframe. I looked around the web and got the code. This is pure Javascript, doesn’t contain jQuery or any other libraries. Set these functions :

function getDocHeight(doc) {
    doc = doc || document;
    var body = doc.body, html = doc.documentElement;
    var height = Math.max( body.scrollHeight, body.offsetHeight,
        html.clientHeight, html.scrollHeight, html.offsetHeight );
    return height;
}
function setIframeHeight(id) {
    var ifrm = id;
    var doc = ifrm.contentDocument? ifrm.contentDocument: ifrm.contentWindow.document;
    ifrm.style.visibility = ‘hidden’;
    ifrm.style.height = "10px"; // reset to minimal height in case going from longer to shorter doc
    // some IE versions need a bit added or scrollbar appears
    ifrm.style.height = getDocHeight( doc ) + 4 + "px";
    ifrm.style.visibility = ‘visible’;
}

If long long Javascript codes are compressed, it will make the page load faster. In this post I’m going to suggest a perfect tool for compressing Javascript code. The tool is JsCompress.
Go to http://blimptontech.com/ to see the compressor in action.
You have three options:

1. Paste Code and Compress
2. Compress code in files
3. Compress Multiple files into one.

It’s a great tool and it will help you reduce the file size up to 100 KB. This site is similar to the JsCompressor tool @ http://jscompress.com. 

Well, this problem is pretty annoying to everyone who is using Dynamic Views, even to me. It’s a Blogger fault as always and there has not been a solution to the problem since it started on the Dynamic Views launch. Päivi & Santeri of Global Nomads founded a solution to this problem. Oh! I didn’t said the problem was. The problem is that the whole Blog will fail to load completely/properly. Some of the problems happen when the blog won’t properly load are listed below:

If you want to redirect users to a specific page or url like when user is not logged in or something in PHP then you can accomplish this with header function or by Javascript printed by echo function.
The following example will redirect user to http://subins.hp.af.cm

Or you can use the normal Javascript :

window.location=’http://subins.hp.af.cm’;"; ?>

What’s the difference ?

header function is called in server itself not when the page reaches the browser. So no content will load, instead the client’s page will be redirected to the specified url.
