Javascript validation on editable tableview column

Question

Hi,
Sample scenario:
I have provided users with an option to enter say quantity in an editable column of tableview in all 5-6 rows. Now I want to check if the entered quantity is a numeric field or not.
Query:
had it been a single input field I could have written:
<_script for="Quantity" _event=onchange _type="text/javascript">
followed bt the required check
but in this case there is an editable column of a table view and so I am unable to identify the element to write the javascript.
Please help

Hi Saurabh,
Use tableView iterator method render_cell_start to define a call a javascript function for validation of entered value.
Something like...
case p_column_key
when 'QTY' .
IF p_edit_mode is not initial.
DATA: find type string,
            replace type string.
DATA: obj_fr type ref to cl_bsp_find_and_replace ,
           obj_bee type ref to cl_bsp_bee_table.
DATA: qty type ref to cl_htmlb_inputfield.
find = '<input' .
replace = `<input on_change="checkQTY(this.value,this.name);" . <--this line of code will call a JS function and pass it                                                                                the value of this field and name of this field.
obj_fr = cl_bsp_find_and_replace=>factory( find = find
                                                                        replace = replace
                                                                        mode = 'FIRST_OCCURANCE' ) .
qty = cl_htmlb_inputfied=>factory( id = p_cell_id
                                                        type = 'num'  ) .
CREATE OBJECT obj_bee.
obj_bee->add( level = 1 element = obj_fr ) .
obj_bee->add( level = 2 element = qty ) .
p_replacement_bee = obj_bee .
ENDIF.
Now in the layout of BSP page you define the JS function
checkQTY(val,name)
and check the entered value and the name of inputield where it was entered.
This name of inputfield will change dynamicaly when ever a new row is selected and page is refeshed.
