FormAPI Help! Can't Get Multiselect Values

whysguy

I need to loop through the items selected in a multi-select box and append the value for each selected item to a variable. The code below works when one item is selected, but it craps out when I select more than one. The function is called onItemChange [ProductLineMultiItem is the variable for IWDatacapture.getItem("/categorization/product_line_multiple")]:


// We need to create the products query string dynamically
function createProductsQueryString()
{
var productsQueryString = "";
var selectedProductLines = ProductLineMultiItem.getValue();
for (var i = 0; i < selectedProductLines.length; i++)
{
var currentIndex = selectedProductLines;
var thisProductLineValue = ProductLineMultiItem.getOptions()[ProductLineMultiItem.getValue(currentIndex)].value;
productsQueryString = productsQueryString + " " + thisProductLineValue;
}
alert(productsQueryString);
}


I am working on a tight time-line so any help would be appreciated.

Thanks in advance.

Not sure - just taking a guess, but perhaps you need to change:

var selectedProductLines = ProductLineMultiItem.getValue();

to

var selectedProductLines[] = ProductLineMultiItem.getValue();
