Comment Statements


//single-line comment // comment //multiline comment /* comment / //single-line conditional comment //@CondStatement //multiline conditional comment /@ condStatement @/*

The condStatement argument above is conditional compilation code to be used if conditional compilation is activated. If Syntax 3 is used, there can be no space between the "//" and "@" characters.

Use comments to keep parts of a script from being read by the JScript parser. You can use comments to include explanatory remarks in a program.

If Syntax 1 is used, the parser ignores any text between the comment marker and the end of the line. If Syntax 2 is used, it ignores any text between the beginning and end markers.

Syntaxes 3 and 4 are used to support conditional compilation while retaining compatibility with browsers that do not support that feature. These browsers treat those forms of comments as syntaxes 1 and 2 respectively.

The following example illustrates the most common uses of the comment statement.

В	Copy Code
function myfunction(arg1, arg2){ /* This is a multiline comment that can span as many lines as necessary. */ var r = 0; // This is a single line comment. r = arg1 + arg2; // Sum the two arguments. return(r); }

В

Copy Code

function myfunction(arg1, arg2){
   /* This is a multiline comment that
      can span as many lines as necessary. */
   var r = 0;
   // This is a single line comment.
   r = arg1 + arg2; // Sum the two arguments.
   return(r);
}
