Hi everyone. We know that Javascript is compiled when the browser loads your webpage. However, sometimes you need to compile your script loaded by Ajax, how should you do? As default, the browser doesn’t compile the script responded by Ajax. If you use the function eval() to compile your script, the variable (defined in your Ajax response code) will be unavailable to call in your page. Thus I have a tip that may help you solve this issue. You can call the function below to compile your script loaded by Ajax.

// Compile your custom script
function compileJsAjax(yourScript){
    var jsElement = document.createElement('script');
    jsElement.type = 'text/javascript';
    jsElement.text = yourScript;
    var existedJs = document.getElementsByTagName('script')[0];
    existedJs.parentNode.insertBefore(jsElement,existedJs);
}

I was just adding my site on Alexa and in some minutes Alexa generated a thumbnail of my html site. And again it was same with blog catelog. So I thought is there any PHP code that crawled the site and generates its image thumb? After a lots of research I came out with these. Remember, this only works in windows server.
There is one thing called IECapt.exe ( A Internet Explorer Web Page Rendering Capture Utility). This renders the page and generate thumbnail of it. You can download it from IECapt.exe. And to run that through php here’s the code.

This is the class file that generates thumb images from the output of IECapt.exe. Save it as image.class.php
