Can anyone provide me some details about the [$(‘3] used in a java script e.g. $('#select_text').XYZ. I saw this in a .js file but when I try to use it in my javascript it gives some error. In the given example the “select_text” is a id of a text box in the web page which include the .js file containing the $ code.
Can anyone provide me some tutorial about this “advance” javascript.
