Hi,
I have implemented your dependent listbox drop down feature as show in your download. However when I try to do 2 or 3 levels of dependencies, the url will return an incorrect one. There will be a missing ? when I do the 2nd selection.
The additional code are as followed
Put this after the <title>
<script>
// Added by DNB, removes "parameter" from this page's window.location.href
// The item removed is something like "?parameter=value" (or it may start with "&")
function removeFromURL(URi, parameter) {
var regexp, path, params, qStart = URi.indexOf('?') + 1;
if (qStart == 0 || qStart == URi.length-1) return URi;
regexp = new RegExp("(" + parameter + "=[^&]+(&)?)");
return URi.substring(0,qStart-1) +
URi.substring(qStart).replace(regexp,'').replace(/&$/,'');
}
</script>
These are the 2 codes for the on change
//page_Record_ProductCategoryID_OnChange @25-93CEAB07
function page_Record_ProductCategoryID_OnChange()
{
var result;
//End page_Record_ProductCategoryID_OnChange
//Custom Code @32-2A29BDB7
// -------------------------
var strURL = removeFromURL(window.location.href,"ProductCategoryID");
if (strURL.indexOf("?") > 0) {
window.location.href = strURL + "&ProductCategoryID=" + this.value;
}
else {
window.location.href = strURL + "?ProductCategoryID=" + this.value;
}
// -------------------------
//End Custom Code
//Close page_Record_ProductCategoryID_OnChange @25-BC33A33A
return result;
}
//End Close page_Record_ProductCategoryID_OnChange
//page_Record_ProductModel_OnChange @26-9EC27DE4
function page_Record_ProductModel_OnChange()
{
var result;
//End page_Record_ProductModel_OnChange
//Custom Code @36-2A29BDB7
// -------------------------
var strURL = removeFromURL(window.location.href,"ProductModel");
if (strURL.indexOf("?") > 0) {
window.location.href = strURL + "&ProductModel=" + this.value;
}
else {
window.location.href = strURL + "?ProductModel=" + this.value;
}
// -------------------------
//End Custom Code
The onchange fot productcategory returns a correct URL of
http://localhost/ToshibaWarranty/Registration.asp?ProductCategoryID=4
The error occurs only when I do a selection on the ProductModel. It will return the following URL.
http://localhost/ToshibaWarranty/Registration.aspProduc...oductModel=DVD1
But I saw from the code that it is supposed to be appended with & instead of adding a $. Why this error occurs?
