Hi.

I want to add (opposite of subtract) some values in the form. The form is located at www.e-xploder.net/harici/form

In this form, there is no problem when adding (when you enter some values in form fields, script adds them and writes the total in "I Alt" area). But, I want to add top 5 values. So, for example, when I enter 5,2,6,8,10,20,30 in fields, in "I alt" area it must be 74 (30+20+10+8+4).

Is there a script like this? Please help. I don't have any experience on JS and can't understand codes.

Yours sincerely.
(Sorry for my English)

Code:

function calc(){
        var theValues=new Array(parseInt(document.autoSumForm.s1c.value), // Add all values to an array
                parseInt(document.autoSumForm.s1p.value),
                parseInt(document.autoSumForm.s2c.value),
                parseInt(document.autoSumForm.s2p.value),
                parseInt(document.autoSumForm.s3c.value),
                parseInt(document.autoSumForm.s3p.value),
                parseInt(document.autoSumForm.s4c.value),
                parseInt(document.autoSumForm.s4p.value),
                parseInt(document.autoSumForm.s5p.value),
                parseInt(document.autoSumForm.s5c.value),
                parseInt(document.autoSumForm.s6p.value),
                parseInt(document.autoSumForm.s6c.value),
                parseInt()document.autoSumForm.finale.value)
        theValues.sort(mySort)
        document.autoSumForm.ialt.value = (theValues[0]+theValues[1]+theValues[2]+theValues[3]+theValues[4]);
}

function mySort(a,b){
        return a-b
}

I think that should work, but I'm not sure if the quick way to do numerical sorting was to do a-b or b-a in mySort. But I guess you'll notice since if it's the wrong way, you'll get the five smallest values.
Also note that non-numerical values will mess up the script.
If you want to only allow numbers in a field, try this:

Code:

function Cleanup(field){
	input=field.value.substring(0,20) // Set absolute max length to 20
	while(/\D/.test(input)){
		input=input.replace(/\D/,'')
	}
	while(input.substring(0,1)=="0"){
		input=input.substring(1)
	}
	if(input==''){
		input=0
	}
	field.value=input
}

...

<input type="text" onchange="cleanup(this)">

Thanks TwoD.

Your codes are great. I've tried this and it works.

Code:

function calc(){
	var inputnames = "s1c s1p s2c s2p s3c s3p s4c s4p s5p s5c s6p s6c s7c s7p s8c s8p s9c s9p s10c s10p s11c s11p s12c s12p finale".split(" ")
	var values = []
	for (var i = 0; i < inputnames.length; ++i)
		values[i] = +document.autoSumForm[inputnames[i]].value
	values.sort(function(a,b) { return b - a })
	values.length = 5
	document.autoSumForm.ialt.value = eval(values.join("+"))
}

Umm why first put the names in a string, and then split them?
You might as well do

Code:

var inputnames = ["s1c","s1p","s2c","s2p","s3c","s3p","s4c","s4p","s5p","s5c","s6p","s6c","s7c","s7p","s8c","s8p","s9c","s9p","s10c","s10p","s11c","s11p","s12c","s12p","finale"]

I do not recommend using eval(). (search Google for "eval is evil" and you'll find out why)

So, I will do yours. Thanks again
