Make jQuery library available to any webpage using Browser JavaScript Console

Hey there,

jQuery is a powerful & easy to use JavaScript library for DOM manipulation. You can do alot of activities in the HTML DOM with this awesome library. Normally I play with jQuery within the Browser Console (Using Firebug in Mozilla Firefox/Chrome Dev Tools in Google Chrome) So I can play inside HTML DOM using this library with one condition that JQuery has to be present in the webpage already. But in some cases, You might have noticed an unavailability of jQuery in some websites. So In that case, you can’t apply any jQuery methods using the browser console. But You can still play with jQuery functions by dynamically including the library using the Console itself. The below JavaScript will help you to do so.



Now you can perform normal jQuery functionalities inside HTML DOM just like the below example.

That’s it. Cheers..!! :)

Simple HTML parsing using PHP DomDocument With Example

Hey there,

Here I’m just giving an example about how to parse a HTML document with the help of PHP’s DomDocument class. This example is intended for a beginner, with little or limited knowledge about parsing HTML using PHP. In this example I’m using this web page (Included in the Source Code Zip) as a HTML document. This web page is a list of all top country level domains owned by Google & related details (which include Extension, Country Name, Language & ISO etc.). We’ll look into how to fetch all those data using DomDocument class. If you refer to the HTML source, you could see all those data like Top level domain, Extension contained with in <td> elements within different <tr> elements . So our main task is to fetch all <td> values. I’m giving the PHP code used to fetch those data.

I’ll explain the source code below :

Initially I’ve created an object variable ($dom) for DOMDocument class

Here used PHP’s file_get_contents function to fetch the HTML content.

Loading HTML source using DomDocument loadHTML function.

Get all <tr> elements

Loop through all <td> elements & respective elements to fetch all required data.

You could see I’ve used getElementsByTagName again to fetch all <td> elements as well. If you execute this PHP code, you can print all values contained within all <td> elements.

That’s it. You can Download the source Here.  Share it..Cheers..:)
