How to clear a htmlb inputField?

Posted on Jun 16, 2004 at 12:31 PM 15 Views

Hi experts,

I do have an html inputField on an stateless bsp page. Sometimes I want to clear the content of the field, but the inputField always displays the content of the last request, even if I've cleared LTEXT before next display in layout.

<%clear ltext. %>

<htmlb:inputField id = "field" value = "<%LTEXT%>"/>

I debugged a little bit and recognized, that the inputField always is filled from the last request, if it's empty. How could I deactivate this feature?

Any ideas?

regards, Claudia

    Hallo Claudia-

    Could it be that perhaps you are missing the '=' sign in your parameter assignment into the HTMLB input-field?

    I have had this field clearing requirement in many of my BSP applications as well and I have been able to accomplish this by setting the parameter 'value' of the HTMLB input-field to an attribute (that after initialization, takes in the value of this control). After initialization, I assign the value of the HTMLB input-field to an attribute and then keep the value there or empty it based on certain conditions. This way, I have control of when the input shows back in the HTMLB input-field and when it doesnt.

    Hope this helps,

    - Vik.

    Sample BSP Code:

    <%

    if <certain condition exists>

    selname = selname.

    else.

    selname = ''.

    endif.

    %>

    <htmlb:inputField id = "selname"

    value = "<%= selname %>"

    size = "10"/>

    Claudia,

    Maybe you are using SP27 or SP28?

    Looking at note 616900 (number which is written on your monitor), you find this entry of help:

    Service Packs: 27-28

    Note: 653167

    Text: <htmlb:inputField> value display doesn't clear
