hi everyone,
i really appreciate if someone could help me. for two days im tring to figure it out alone but its not working.
im writing a shoping list to my project at school. i have a table (shopinglist) that contain the form.
in the form i have 2 drop down list, one (product) is getting the values from my database and the second one (quantity)is constant numners. next to these two i have 2 buttons add and remove.
when pressing add i want to add a new row with the same stuff.
the problem is that i can't (or mybe don't know) how to change the select name according to the row number. i mean like <select name="product_3"- distint names to each select option. its important becuase i need to use the selections with asp code and enter it to my database.
one last thing- the row will be added only if the user choose from both selection, not only from one. pleaseeee try to help me...
here is my code:
the javascript add and remove functions:
Code:
 function addRow(tableID) {
  
if (document.getElementById("product").value!="dafult" && document.getElementById("quantity").value!="zero") 
{
            var table = document.getElementById(tableID);

        var rowCount = table.rows.length;
        var row = table.insertRow(rowCount);

        var colCount = table.rows[0].cells.length;

            var colCount = table.rows[0].cells.length;
	
            for(var i=0; i<=colCount; i++) {
			 var newcell = row.insertCell(i);
                 newcell.innerHTML = table.rows[1].cells[i].innerHTML;
 			  switch(newcell.childNodes[1].type) {
                case "text":
                        newcell.childNodes[1].value = "";
                        break;
                case "checkbox":
                        newcell.childNodes[1].checked = false;
                        break;
                case "select-one":
                        newcell.childNodes[1].selectedIndex = 0;
                        break;
				
                }
            }
			  newcell.childNodes[1].visible = true;
			  table.rows[rowCount-1].cells[2].style.visibility="hidden" ;
			}
            else
          {
            if (document.getElementById("product").value!="dafult" && document.getElementById("quantity").value=="zero") 
                
                 alert("please choose quantity") ;
               if (document.getElementById("product").value=="dafult" && document.getElementById("quantity").value!="zero") 
                alert("please choose product") ; 
               if (document.getElementById("product").value=="dafult" && document.getElementById("quantity").value=="zero") 
                    alert("please choose product and qantity") ;
           }
            }
       
        function deleteRow(i){
		if (document.getElementById("product").value!="dafult" && document.getElementById("quantity").value!="zero") 
			document.getElementById('shopinglist').deleteRow(i)
		else
			alert("you can't delete row before adding it");
}
