JavaScript: String trimming and padding

msh134 — Wed, 19 Nov 2008 09:57:59 +0000

When working with JavaScript in one of my projects I needed to trim strings and pad them. I googled for a solution and many sources I have got the following codes and sharing with you.

Trimming:

//trimming space from both side of the string
String.prototype.trim = function() {
	return this.replace(/^\s+|\s+$/g,"");
}

//trimming space from left side of the string
String.prototype.ltrim = function() {
	return this.replace(/^\s+/,"");
}

//trimming space from right side of the string
String.prototype.rtrim = function() {
	return this.replace(/\s+$/,"");
}

Using Trim Functions:

//write the code given above
var str = "  black  ";
alert("a" + str.trim() + "b");   //result "ablackb"
alert("a" + str.ltrim() + "b");  //result "ablack b"
alert("a" + str.rtrim() + "b");  //result "a blackb"

SSL (HTTPS) URLs and CodeIgniter

msh134 — Tue, 28 Oct 2008 15:31:38 +0000

I am a fan of CodeIgniter for its ease of use. I have developed several ecommerce projects using this “beautiful” framework. While working on my first ecommerce project with CodeIgniter, I faced a problem with URLs. The site was suppose to use both “http” and “https”. But with CodeIgnitor we can define one base URL, which can be either “http” or “https”. Then I came up with an idea and now I am going to share that idea with you.

DOMPDF without PDFLib as back-end PDF support

msh134 — Sat, 21 Jun 2008 15:59:42 +0000

I was implementing PDF generation in one of projects which is built with CodeIgniter. I searched for PDF support for CodeIgniter and found issue. I was happy, but the problem was with the PDFLib. Its not free and our client would not buy it. I thought that DOMPDF will not work without the help of PDFLib. Soon I loss my happiness and started looking for an alternate solution. Then our team decided to use HTML2FPDF. But the result was not satisfactory. We had to rewrite our html files. It was lacking lots of HTML support. I was not happy with the output. So I started googling again for a PDF library. While searching I came accross a library called HTML2PS/HTML2PDF. But, it seemed to me complex. I again started searching for any solution which will help me use DOMPDF in my project without PDFLib. At last I got the solution from DOMPDF site .

Date control using JavaScript

msh134 — Sat, 21 Jun 2008 15:52:45 +0000

Date control is a combination of three drop downs with month, day and year valus. It can be used as an alternative to the date picker control. Suppose a user needs to select a date before/after 10 years. At this point selecting the date with a date picker will not be easy and time consuming. So, in this situation, this control may be helpful.

Regular Expression Patterns

msh134 — Sat, 21 Jun 2008 15:50:32 +0000

From various sources I have collected the following regular expression patterns. They helped me a lot in front-end and back-end validation.

Alpha:

Pattern: ^[a-zA-Z_ ]+$
Description: Allows only ‘A-Z’, ‘a-z’, space ( ‘ ‘ ) and underscore ( ‘_’).

Alphanumeric:

Pattern: ^[a-zA-Z0-9_ ]+$
Description: Allows only ‘A-Z’, ‘a-z’, ‘0-9′, space ( ‘ ‘ ) and underscore ( ‘_’).
