This helped me in writing an HP WebOS app in which a method returns a version number of the application(such as 1.1.9), but this script allowed me to change that to 119. Thanks!!!

I also recently discovered a way to do something similar to above (i.e. replace ‘%’ with ‘D’).

As an example, you might want to allow a user to fill in a text area including usage of letters ‘p’, ‘m’, ‘x’, and ‘d’ in place or arithmetic operators ‘+’, ‘-’, ‘*’, and ‘/’.

Note p, m, x, and d are abbreviations for ‘plus’, ‘minus’, ‘times’ (x), and ‘divide’.

The reason for this might be to save time when typing numerous short formulas. (Formulae? anyway…) So to save from having to use the Shift+’=’ (for ‘+’) and Shift+8 (for ‘*’), you may type “3p4″ for “3+4″, etc.

Anyway, so this is reversible as well, but the way to solve it using my example above is with a statement/function similar to this:
‘+-*/’.charAt(‘pmxd’.indexOf(operator))
where ‘operator’ is the p, m x, or d which you have to discover before applying the “search & replace”-like function…

You’d probably need to use regexp’s with match/search/replace if you needed to do the same with something that had char.length of greater than one…

@Nizamudeen,

[code]
'abc%efg'.replace(/%/gi,'D')
[/code]

should work.

@Jayakrishnan Some of those characters need to be escaped.

i have a search string and i nedd to get rid off the characters -,?~!@#$%&*+-=”‘
i tried using the regular expression /[-,?~!@#$%&*+-="']/g
i’m using jQuery
my code is
var queryString = $(“#searchq”).val();
queryString = queryString.replace(/[-,?~!@#$%&*+-="']/g,”);
$(“#searchq”).val(queryString);
but unfortunately after using this it can be seen that even the digits get replaced.
also . gets replaced. whats wrong with my regular expresion

[...] This blog entry contains some helpful information about removing special characters from a string using javascript. I was able to modify it to be just a few of code in an onchange event. Just rename new_name to the attribute your correcting. [...]
