Modify Variable

Removes a character from a variable's value in a string. For example, if you tell it that number equals "0.09876" and to remove the period, afterwords number equals "009876" Neat!


Insert into <HEAD>


Insert into <BODY>
<SCRIPT LANGUAGE="JavaScript"> <!-- Begin var number = "0.09876"; // previous value var removechar = "."; // character to remove from string document.write("Initially, number equals " + number); dec = number.indexOf(removechar); tmp = number.substring(0,dec); tmp += number.substring(dec+1,number.length); number = tmp; // number now equals converted value document.write("<br>Now, number equals " + number); // End --> </script>
