How can i get a selected value from combo box ? i used combo.selectedItem.But it is not working.will u pls give me a solution for this
HTML doesn't have a "combobox" control. Do you mean a "select" element? If your select element has an id of "x", you would get the value of the selected option:
Proper terminology is very important in any technical discussion.
x.options[x.selectedIndex].value;Proper terminology is very important in any technical discussion.
you can have a hidden field in your form, and then set the value using js before it is passed to php.
