Hi all~~
Do anyone know how to get the value of checkbox in client side??
It is because I have something similar to the order entry in the example pack..
however, I have to keep track of the total, which must always be zero..
My thought is to check whether the checkbox(delete) is checked..if yes, then deduct the value from the total..so that I can do the validation in client side...
I have modified the codes in Show_Total():
function Show_Total()
{
var TotalSum=0;
var Summ;
for(var i = 0; i < store_orders_itemsElements.length; i++){
Summ = StrToFloat(store_orders_itemsElements[ i ][store_orders_itemspriceID].value) *
StrToFloat(store_orders_itemsElements[ i ][store_orders_itemsquantityID].value);
TotalSum = TotalSum + Summ;
if (Summ == 0) {
store_orders_itemsElements[ i ][store_orders_itemsSumPriceID].value = "";
} else {
store_orders_itemsElements[ i ][store_orders_itemsSumPriceID].value = Math.round(Summ*100)/100;
}
if (store_orders_itemsElements[ i ][store_orders_itemsDelete1ID].value == true)
TotalSum = TotalSum - Summ;
}
document.store_orders_items.Total_price.value = Math.round(TotalSum*100)/100;
}
However, it gives me the following error:
'store_orders_itemsElements[ i ][store_orders_itemsDelete1ID]' is undefined
Could somebody give me a hand??
Sorry for so many questions these few days...><"
Best wishes,
Rachel

Hi
Is your store_orders_itemElements actually a 2 dimentional array? If it is and has been initialized with data I would try.
OrderElements = new Array();
var e=document.getElementById("store_orders_itemElements");
OrderElements=e.value;
Then user OrderElements [xxx] [xxx] as your array.
Be sure "store__orders_itemElements" is the actual id for the data field in the html.
If it has not been initialized as an array then you will need to be sure your PHP sends it that way or determine how to convert it to an array in the html.
Does That Help. I am just guessing right now.

Hi,
I just stumble upon this post looking for a solution to my own problem. First my problem is, how to detect the delete control checkbox for a new row? The 'invisible' checkbox appears to return a checked value for a new row!
And here's the solution (hopefully) to your problem. Refer to the delete checkbox as:
store_orders_itemsElements[ i ][store_orders_itemsDeleteControl].checked
Hopefully, this is not too late for you :)
Cheers,
Karen
