Hi,
I have a Javascript total calculation function within a php form that uses onBlur to show the client a running total of the dollar amount of items added: http://www.microtribe.com/dev4Tony/order881x2.php
And I have a linked external PHP file/script to email the results of the form to me. All works fine but I can't figure out how to grab the total dollar amount ("sub_total") created by the Javascript with this line:
document.getElementById('sub_total').innerHTML = '$ ' + runningTotal.toFixed(2);
Is there a way to have the Javascript send this variable to my php script?
Here is the full Javascript Function:
<code>
/*Addition Function
*/
var elements = new Array();
function calculatePrice(price,me,id) {
var newValue = 0;
if (me.value == 0) {
document.getElementById('total' + id).innerHTML = '';
} else if (me.value > 0) {
newValue = price * me.value;
document.getElementById('total' + id).innerHTML = newValue.toFixed(2);
}
elements = newValue.toFixed(2);
calculateTotal();
}
function calculateTotal() {
var runningTotal = 0;
for (var strCurrentKey in elements) {
runningTotal += parseFloat(elements[strCurrentKey]);
}
var sub = runningTotal.toFixed(2);
var tax = sub * 0.00;
var total = sub * 1.08375;
document.getElementById('sub_total').innerHTML = '$ ' + runningTotal.toFixed(2);
document.getElementById('tax').innerHTML = '$ ' + tax.toFixed(2);
document.getElementById('grand_total').innerHTML = '$ ' + total.toFixed(2);
document.getElementById('field_subtotal').value = runningTotal.toFixed(2);
document.getElementById('field_tax').value = tax.toFixed(2);
document.getElementById('field_total').value = total.toFixed(2);
}
/*Parse number to currency format:
By Website Abstraction (www.wsabstract.com)
and Java-scripts.net (www.java-scripts.net)
*/
//Remove the $ sign if you wish the parse number to NOT include it
var wd;
function parseelement(tempnum){
wd="w";
for (i=0;i<tempnum.length;i++){
if (tempnum.charAt(i)=="."){
wd="d";
break;
}
}
if (wd=="w") {
return tempnum+".00";
} else {
if (tempnum.charAt(tempnum.length-2)==".") {
return tempnum+"0";
} else {
tempnum=Math.round(tempnum*100)/100;
return tempnum;
}
}
}
</code>
Thanks!
Tony
