Calling Functions

[worldtraveller]

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

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

<script type="text/javascript">
	{
showResults=("race[0],name1,party1,votes1");

    }
</script>

or should it be without the { and }

like this?

script type="text/javascript">
	
showResults=("race[0],name1,party1,votes1");

    
</script>

or is it like this

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.

function test(par1,par2) {
    // Declaring
}
test("hello","world"); // Calling

Thank you

would this be proper written format?
for Calling Function

<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");
showResults("race[4]","name5","party5","votes5");
  
</script>

thanks

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

Looking at your example

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?

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

var i = 0;
var results = 5;
var x;

for (i = 0; i < results; i+=1){
  x = i + 1;
  showResults("race["+ i +"]", "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

<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
