Returns as string with HTML <SUB> tags placed around text in a String object.
function sub() : String
No checking is done to see if the tag has already been applied to the string.
The following example demonstrates how the sub method works:
var strVariable = "This is a string object"; strVariable = strVariable.sub();
The value of
strVariable after the last statement is:
<SUB>This is a string object</SUB>
