Sum Number of Textboxes Values?

[barkster]

I have a page where there could be any number of textboxes that are named textbox1, textbox2, textbox3, etc... Without knowing how many there on are the page how can I get all the textbox# values and add them together?  Thanks

var textboxes = document.getElementsByTagName('input');

var count = textboxes.length;

var total = 0;

for(var i  = 0; i < count; i++){

if(textboxes.name.indexOf('textbox') > 0) total += textboxes.value;

}

alert(total);

Cool that worked, though had to do it this way. For some reason when it was adding the values it was adding 2+3 as 23 instead of 5.

 

Thanks

 

var totalcomp = 0;

var totalbill = 0;

for(i=0; i<document.forms[0].elements.length; i++){

    var n = document.forms[0].elements.name;

    if (n.indexOf("tbbtime")>=0) {

    var v = parseFloat(document.forms[0].elements.value);

    totalbill = totalbill + v;

    }

    else if (n.indexOf("tbctime")>=0) {

    var v = parseFloat(document.forms[0].elements.value);

    totalcomp = totalcomp + v;

    }

}
