Java Script Regular Expressions

The following are the some of the java script regular expressions.

var Integer =/^[\-]?\d*$/;
var PositiveInteger =/^\d*$/;
var RealNumber = /^[\-]?\d*$|^[\-]?\d*\.\d*$/;
var PositiveRealNumber = /^\d*$|^\d*\.\d*$/;
var Currency = /^[\-]?[\$]?[\-]?\d+$|^[\-]?[\$]?[\-]?\d+\.\d*$|^[\-]?[\$]?[\-]?\d{1,3}(,\d{3})*\.\d{0,2}$/;
var Currency$ = /^[\-]?[\$]?[\-]?\d*$|^[\-]?[\$]?[\-]?\d*\.\d*$|^[\-]?[\$]?[\-]?\d{1,3}(,\d{3})*\.\d{0,2}$/;
var PositiveCurrency = /^[\$]?\d*$|^[\$]?\d*\.\d*$|^[\$]?\d{1,3}(,\d{3})*\.\d{0,2}$/;
var PositiveCurrency$ = /^[\$]?\d*$|^[\$]?\d*\.\d*$|^[\$]?\d{1,3}(,\d{3})*\.\d{0,2}$/;
var GeneralNumber = /^\d*$|^\d*\.\d*$/;

JAVASCRIPT DATE VALIDATION

The following is the link for Date Validation i.e. Entered date is valid r not.

http://www.expertsrt.com/scripts/Rod/validate_date.php

function validateDate(fld) {

    var RegExPattern = /^(?=\d)(?:(?:(?:(?:(?:0?[13578]|1[02])(\/|-|\.)31)\1|(?:(?:0?[1,3-9]|1[0-2])(\/|-|\.)(?:29|30)\2))(?:(?:1[6-9]|[2-9]\d)?\d{2})|(?:0?2(\/|-|\.)29\3(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00))))|(?:(?:0?[1-9])|(?:1[0-2]))(\/|-|\.)(?:0?[1-9]|1\d|2[0-8])\4(?:(?:1[6-9]|[2-9]\d)?\d{2}))($|\ (?=\d)))?(((0?[1-9]|1[012])(:[0-5]\d){0,2}(\ [AP]M))|([01]\d|2[0-3])(:[0-5]\d){1,2})?$/;

    var errorMessage = 'Please enter valid date as month, day, and four digit year.\nYou may use a slash, hyphen or period to separate the values.\nThe date must be a real date. 2-30-2000 would not be accepted.\nFormay mm/dd/yyyy.';

    if ((fld.value.match(RegExPattern)) && (fld.value!='')) {

        alert('Date is OK'); 

    } else {

        alert(errorMessage);

        fld.focus();

    } 

}

JAVASCRIPT REGULAR EXPRESSION FOR REMOVING SPECIAL SYMBOLS

The following example will give the you the notes to replace the special characters in a string.

Place the following coed with in the script tags.

var temp1;

var temp = new String('Thi\'s is a te!!!!s$t st>ri9ng... S"o??? What#...');

document.write(temp + '
');

temp = temp.replace(/[^a-zA-Z 0-9]+/g,'-');

document.write(temp + '
');

temp1=temp.replace(/\s/g,'-');

document.write(temp1 + '
');
