Javascript and BSPs

Former Member — Wed, 16 Nov 2005 15:34:04 GMT

I have a BSP application where I am displaying the contents of a table on a BSP page, and allowing the user to change the table items. I also want to add some javascript to update some of the fields in the table, but I am having trouble with the indexes.

Here is a sample of my code:

<% loop at t_qtitems into w_qtitems. %>
<input type="text" name="t_qtitems[<%=sy-tabix%>].rqmult"
    size="2" maxlength="5" value="<%=w_qtitems-rqmult%>">
<% endloop. %>

I want to add a button to use javascript to update the input text fields using javascript. However, when I view the web page, I see this as the field name:

<input type="text" size="2" maxlength="5"
  name="t_qtitems[1 ].rqmult">

When I try to use javascript to update this input field, for example:

frmInput.t_qtitems[1 ].rqmult.value=100;

I receive a javascript error "frmInput.t_qtitem.1 is null or is not an object". How do I change the indexed items from this table using javascript?

Denise,

Try with t_qtitems[1 ].rqmult.value=100;

Thanks

That doesn't work. This is javascript where I am doing this change, so I need to reference the html form where the field that I am trying to update resides.

Hi,

Try with

frmInput.elements["t_qtitems[1 ].rqmult"].value=100;

Thanks,

Amara.

Hai Hartman,

I have faced a similar problem,Here when u are naming

the ID or names of input fields make sure that does not

contain "],[,,." special characters.

Make sure you specify the id of the input field.

I am including a sample program where I am updating a

hidden field with the value entered in the input prompt

with javascript .

Page with flowlogic


<%@page language="abap" %>
<%@extension name="htmlb" prefix="htmlb" %>
<htmlb:content design="design2003" >
  <htmlb:page title="Input prompt " >
  <script language="JavaScript" type="text/javascript">
                 function save_input_prompt()
                 {
                  var varient_name = prompt("Save Varient as ?","");
                   if (varient_name == null )
                   return false;
                   else if (varient_name == "" || varient_name == " ")
                    {
                      alert("Enter a valid input");
             	        return false;
                    }
                   document.mainform.if_varient_name.value =varient_name;
                   alert( document.mainform.if_varient_name.value );
                  return true;

                 }
      </script>
    <htmlb:form id="mainform" >

      <htmlb:inputField id    = "if_varient_name"
                        value = "abc"
                        visible = "false" />
      <htmlb:button id            = "save_query_open"
                    text          = "Save as"
                    onClick       = "EVT_SAVE_QUERY"
                    onClientClick = "if(!save_input_prompt()) htmlbevent.cancelSubmit=true;"
                    tooltip       = "Save Query" />
    </htmlb:form>
  </htmlb:page>
</htmlb:content>

input processing .


DATA lv_string TYPE string.
lv_string = request->get_form_field( 'if_varient_name' ).

DATA: data TYPE REF TO cl_htmlb_inputfield.
data ?= cl_htmlb_manager=>get_data( request      = runtime->server->request
                                    name         = 'inputField'
                                    id           = 'if_varient_name' ).
IF data IS NOT INITIAL.
  lv_string = data->value.
ENDIF .

Put a break pointer in inputprocessing to check if you

can retrive the value properly. I have included two ways of retiving

value from the form fields.

Hope this would help you.

Finally,

This is the wrong forum that u have posted this question.

There is a seperate forum for BSP
