    Calling Functions

    Hello all here is a more intelligent question. This one is just on an exercise I am doing.

    I have to call a function using parameter values.

    my main function is this

    Code:
    function showResults(race,name,party,votes)
    
    or just
    
    function showResults
    in the next lines below

    i have to call the function

    is this the right way


    Code:
    <script type="text/javascript">
    	{
    showResults=("race[0],name1,party1,votes1");
    
        }
    </script>
    or should it be without the { and }

    like this?

    Code:
    script type="text/javascript">
    	
    showResults=("race[0],name1,party1,votes1");
    
        
    </script>
    or is it like this

    Code:
    script type="text/javascript">
    	
    showResults(race[0],name1,party1,votes1);
    
        
    </script>
    Thanks all, what would be the proper method

    Thanks

    Only the latter is JavaScript.
    Code:
    function test(par1,par2) {
        // Declaring
    }
    test("hello","world"); // Calling
    Great wit and madness are near allied, and fine a line their bounds divide.

    for Calling Function

    Code:
    <script type="text/javascript">
    	
    showResults("race[0]","name1","party1","votes");
    showResults("race[1]","name2","party2","votes2");
    showResults("race[2]","name3","party3","votes3");
    showResults("race[3]","name4","party4","votes4");

    You need to do a bit of reading up. There is a lot to learn about functions.

    For starters you could try googling 'javascript functions', 'javascript reference and primitive types' and 'javascript variable scope'.

    A few links I found after a quick search

    http://www.quirksmode.org/js/function.html
    https://developer.mozilla.org/en/Jav...function_scope
    http://www.howtocreate.co.uk/tutoria...ript/functions
    http://docstore.mik.ua/orelly/webpro...pt/ch04_04.htm
    http://docstore.mik.ua/orelly/webpro...pt/ch11_02.htm

    Looking at your example
    Code:
    showResults("race[0]","name1","party1","votes");
    showResults("race[1]","name2","party2","votes2");
    showResults("race[2]","name3","party3","votes3");
    showResults("race[3]","name4","party4","votes4");
    showResults("race[4]","name5","party5","votes5");
    One additional goal would be to look at a way of reducing the repetition in your script. Maybe using a loop for example?

    PHP Code:
    var showResults = function(racenamepartyvotes){
      
    // just testing
      // console.log needs Google Chrome or firefox and the firebug plug-in.
      
    console.log (race ' - ' name ' - ' party ' - ' votes);
    }

    var 
    0;
    var 
    results 5;
    var 
    x;

    for (
    0resultsi+=1){
      
    1;
      
    showResults("race["+"]""name" x"party" x"votes" x);
    }
    /*
    Output from showResults test
    race[0] - name1 - party1 - votes1
    race[1] - name2 - party2 - votes2
    race[2] - name3 - party3 - votes3
    race[3] - name4 - party4 - votes4
    race[4] - name5 - party5 - votes5
    */

    I made a mistake with my call function

    it should be like this
    Code:
    <script type="text/javascript">
    	
    showResults(race[0],name1,party1,votes1);
    showResults(race[1],name2,party2,votes2);
    showResults(race[2],name3,party3,votes3);
    showResults(race[3],name4,party4,votes4);
    showResults(race[4],name5,party5,votes5);
      
    </script>
    Well for the exercise i was supposed to be inputed in this manner, so far my entire program is not working though
