whats this

[davebat]

why do some lines of javascript code have ";" at the end.

[bekkel]

else you get an error

it's to close the 'function'

[davebat]

I wrote the following and removed all the ";" and it didnt error at all

<script language="JavaScript">
    function checker(){
        var complete  = "F" ;
        var message   = ""  ;
        var error     = ""  ;
        var acc_count = 0   ;
        var text      = ""  ;
        for (i = 1; i <= count; i++){
            dave = eval("document.pc_app.F_PROF_"+i) ;
            if (dave[0].checked || dave[1].checked || dave[2].checked || dave[3].checked){
                complete = "T" ;
            }else{
            message = message + (i + " ") ;
            error = "Y" ;
            }
        }
        for (i = 1; i <= count; i++){
            dave1 = eval("document.pc_app.F_PROF_"+i) ;
            if (dave1[3].checked){
                acc_count = acc_count + 1 ;
            }
        }
        if (acc_count == count){
            complete = "F" ;
            text  = "You have selected 'No Access' for\nevery module. Please try again." ;
        }
        if (error == "Y"){
            complete = "F" ;
            text = ("Please select an ability profile\nfor module(s): " + message) ;
        }
        if (complete == "F"){
            alert(text) ;
            return false ;
        }else{
            return true ;
        }
    }   
</script>

does anyone else know what the semi-colons are for?

[techgnome]

in JAvascript, they indicate the EOL or end of the line.... some languages live VB use the CRLF as the EOL.... most other languages use ; .....

Did it work at all?

In JS, ; is the EOL marker. Nothing magical or extra.

[morrowasted]

in a lot of languages they use ; , not just JS

[jeffmott]

In JS, ; is the EOL marker

More accurately it is a statement terminator. In JavaScript a newline is also a statement terminator. The only time a semi-colon is required is if you wanted to put two statements on the same line. e.g.,

x += 2; y -= 1
