Question

I am trying to pass a variable to a a function that I believe calls another function (I think) but am having problems. The variable I need to use in the second function is productid but several ways thAt I have tried have not worked. either a fix in javascript or Jquery will be great!!!

This is the line that I need the variable for

var error_url = '/ProductDetails.asp?ProductCode'  + productid;

this is where the variable originates from…

var productid = form.elements['ProductCode'].value;

and here is the whole js code

function addToCart2(form, button) {
var softAdd = true;
var productid = form.elements['ProductCode'].value;

      var qstr;
  var bttnName = button.name;
    button.disabled = true;
    if (form.elements['ReturnTo']) {
        form.elements['ReturnTo'].value = "";
    }
    qstr = serialize(form, bttnName + '.x', '5', bttnName + '.y', '5');
            sendAjax('POST','/ProductDetails.asp?ProductCode=' + productid  + '&AjaxError=Y', qstr , retrieveProductError2 ,displayServerError,false);
    button.disabled = false;
            return false;
        }
function retrieveProductError2(result, statusCode) {
var ele = document.getElementById('listOfErrorsSpan');
var errorIndex = result.indexOf('<carterror>');
var productIndex = result.indexOf('<ProductIndex>')
if (errorIndex > -1 && productIndex == -1)  {
var error_url = '/ProductDetails.asp?ProductCode'  + productid;
window.location = error_url;
} 
if (errorIndex != -1) {
    //ele.innerHTML = result.slice(errorIndex + 11, result.indexOf('</carterror>'));
}
else {
    ele.innerHTML = "";
    if (productIndex == -1) {
    sendAjax('GET','/AjaxCart.asp?GetIndex=True', '', showCart, null, false);
    }
    else {
    productIndex = result.slice(productIndex + 14, result.indexOf('</ProductIndex>'));
    sendAjax('GET','/AjaxCart.asp?Index=' + productIndex, '', showCart, null, false);
    }
}

}

Answer 1

Where you pass in retrieveProductError2 as your error callback for the sendAjax call, you could instead pass in:

function(result, statusCode) { retreiveProductError2(result, statusCode, productId);}

Then change the definition of your retreiveProductError2 function to accept the additional parameter.
