Connect with CDN

<script src="https://www.unpkg.com/datatype-validation@latest/datatype.js" type="text/javascript"></script>

Usage

To use existing functions, use datatype.functionName(value), here is an example of its use:

Check data type

String

datatype.isString("test"); //This will return true, because the value entered is a string

datatype.isString(123); //This will return false, because the value entered is not a string but a number

Number

datatype.isInt(123); //This will return true, because the value entered is a number

datatype.isInt("lol"); //This will return false, because the value entered is a string, not a number

datatype.isInt(123.4); //This will return false, because the value entered is a decimal number, not an integer number


datatype.isFloat(123.4); //This will return true, because the value entered is a decimal number

datatype.isFloat(123); //This will return false, because the value entered is not a decimal number but an integer number

Boolean

datatype.isBoolean(false); //This will return true, because the value entered is a boolean, not a string or number


datatype.isBoolTrue(true); //This will return true, because the value entered is a boolean that contains the value true not false


datatype.isBoolFalse(true); //This will return false, because the value entered is a boolean that contains the value true, not false

DateTime

datatype.isDate("18-11-2023"); //This will return true, because the value entered is in date format

datatype.isDate(18-11-2023); //This will return false, because to do this it must be in string format

//You can do this in any delimiter/combiner for example I used (-) you can also use spaces or whatever you think is suitable

//Example:
datatype.isDate("18 11 2023");
datatype.isDate("18~11~2023");
datatype.isDate("18:11:2023");


datatype.isTime("10:30:58"); //This will return true, because the value entered is in time format

datatype.isTime(10:36:25); //This will return false, because to do this it must be in string format

//You can do this in any delimiter/combiner for example I used (:) you can also use spaces or whatever you think is suitable

//Example:
datatype.isTime("10-38-40"); 
datatype.isTime("10 39 50"); 
datatype.isTime("10|42|30"); 


datatype.isDateTime("18-11-2023 10:45:15"); //This will return true, because the value entered is in date and time format

datatype.isDateTime(18-11-2023 10:48:56); //This will return false, because to do this it must be in string format

//You can do this in any delimiter/combiner for example I used (- and :) you can also use spaces or whatever you think is suitable

//Example:
datatype.isDateTime("18 11 2023 10 57 59");
datatype.isDateTime("18/11/2023 10-58-35");
datatype.isDateTime("18:11:2023 11-14-06");

Other

datatype.isDomain('example.com'); //This will return true, because the value entered is valid domain

datatype.isDomain('https://lol.net'); //This also result the value true

datatype.isDomain('http://lol.xyz'); //This also result the value true

datatype.isDomain('https://blog.lol.com'); //This also result the value true

datatype.isDomain('https://blog.lol.i'); //This will return false, because the domain extension is invalid


datatype.isIPAddress('192.168.1.1'); //This will return true

datatype.isIPAddress(192.168.1.1); //This will return false, because javascript thinks this is a mathematical operation

Change data type

String

datatype.toString(1234); //This will return a value in the form of string "1234"

Number

datatype.toInt("12.5"); //This will convert the string float value to int (12)

datatype.toFloat(25); //This will convert the value int (25) to float (25.0)

Boolean

datatype.toBoolean("lol"); //This will convert or return boolean value true

datatype.toBoolean(""); //This will convert or return boolean value false

datatype.toBoolean(1); //This will convert or return boolean value true, if value number > 0

datatype.toBoolean(0); //This will convert or return boolean value false, if value number < 0
