Question

When values are entered into 2 TextBox's(textbox1 & textbox2) they are multiplied with one another and the answer is displayd in a Label(label1), I need to add all the labels and display it in another label, this has to be don without buttons.

When the TextBox's change this function is called.

function Calculate(textbox1, textbox2, label1)
    {
            var txt1 = 0;
            var txt2 = 0;
            txt1 = document.getElementById(textbox1).value;
            if (txt1 == "")
                txt1 = 0;
            
            txt2 =  document.getElementById(textbox2).value;
            if (txt2 == "")
                txt2 = 0;

            var cost = txt1 * txt2;
            document.getElementById(label1).innerHTML = cost;
    }

at the end of calculate function you may add code

FUNCTION CALCULATE
{
.
.
.
.
     document.getElementById(label1).innerHTML = cost;

     document.getElementById(label3).innerHTML = parseFloat(document.getElementById(label1).innerHTML) + parseFloat(document.getElementById(label2).innerHTML);
}

var total=0;
for (i=1;i<=15;i++)
{
  total+=parseFloat(document.getElementById('label'+i).innerHTML); 
}
document.getElementById(label3).innerHTML = total;

Ok, this function is called about 15times, so I'm not sure how to get all the labels to asdd together for

document.getElementById(label3).innerHTML = 
            parseFloat(document.getElementById(label1).innerHTML) + 
            parseFloat(document.getElementById(label2).innerHTML);

I tried the code and "label3" doesn't change.

change you calculate function at the end as shown below

function calcuate(...........)
{
.
.
.
.

var total = 0;      
for (i = 1 ;i <= 15; i++)      
{        
	if (i<10)
	{
		total += parseFloat(document.getElementById('amount_0'+i).innerHTML);      
	}
	else
	{
		total += parseFloat(document.getElementById('amount_'+i).innerHTML);      
	}
}      
document.getElementById(label2).innerHTML = total;

}

Hi urtrivedi,

thanks for the function, but when the totalLabel should change it says NaN, I know this means not a number, although only numbers are entered into the TextBox.

Test with eval() function in javascript to convert the element value/expression to process a calculation.

I hope this will work

function calculate(.......)
{
 .
 .
 .
 .
 
	var total = 0;      
	for (i = 1 ;i <= 15; i++)      
	{        
		if (i<10)
			labelname='amount_0'+i;
		else
			labelname='amount_'+i;
	
	
		if (!isNaN(parseFloat(document.getElementById(labelname).innerHTML)))
			total += parseFloat(document.getElementById(labelname).innerHTML);      
	}      
	
	document.getElementById(label2).innerHTML = total;
}
