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