input_node.styl e.visibility = val ? 'hidden' : 'visible';
}

</script>
[/CODE]
i chnges it like this is the incorrect if not then no magic

have a look at the line 4 ... you added an if here ... that is useless, so simply remove it and it should work ...

sending the code is not a good idea, may be you have a link to a testpage?

kind regards

hi ...

in your code you have:

[CODE=asp] <td Width="15%"><se lect Id="SEL_ITEM" Name="SEL_ITEM" Size="1">
<option Selected Value>Select Item</option>
<%
Set RSITEM = CON.EXECUTE("SE LECT * FROM CONSUM_ITEMS ORDER BY Item_code")
%>
<%
Do While Not RSITEM.EOF
%> <option Value="<%=RSITE M("Item_code")% >" onchange="toggl e_state(this);" ><%=RSITEM("Ite m_desc")%></option>
[/CODE]
change in a way that the onchange is added to the select-element like:

[CODE=asp]
<select Id="SEL_ITEM" Name="SEL_ITEM" Size="1" onchange="toggl e_state(this);" >
[/CODE]
the onchange mustn't be added to the option-element

kind regards

hi ...

I Used your code but it not work when select option is selected automatic show input field and hide input field based on option

**gits** · Jan 17 '08, 07:58 AM

please explain in detail how the option will get automatically selected? ... in case you do it serverside you have to set the visibility of the input-box accordingly ...

kind regards

hi gits
i don't know about server side and client side
the main things wants to do when user login then a page is open with option to select item, quantity and submit to create requision for item he can add more then one item in same requision to add one by one so when he selected cd and floppy then show the input field if option is cartidge then hide show i don't know which type of code have to write client side or server side.

hi ...

please load your page to a browser and view the source-code -> copy that source-code from the browser, save it as a txt-file and post it here or send me a pm with it ... i have to have a closer look at it ...

kind regards

**idsanjeev** · Jan 17 '08, 10:45 AM

Hi Gits
Thanks for kind supports i attached here both page where these work is need

**gits** · Jan 17 '08, 11:06 AM

hi ...

you posted the asp-code ... but i wanted to have a look at the page when it is loaded to the browser :) ...

let me give you a working example here that uses the code:

[HTML]<html>
<script type="text/javascript">
function toggle_state(ob j) {
// here we check the value of your select-box
var val = obj.value == 'cartridge';

var input_node = document.getEle mentById('purpo se');

input_node.styl e.visibility = val ? 'hidden' : 'visible';
}
</script>
<body>
<select onchange="toggl e_state(this);" >
<option selected="selec ted" value="">select something</option>
<option value="cartridg e">cartridge </option>
<option value="CD">CD</option>
<option value="floppy"> floppy</option>
</select>
<input type="text" id="purpose" style="visibili ty:hidden;"/>
</body>
</html>
[/HTML]
have a look at it ... the onchange HAS to be added to the select and HASN'T to be added to the option (like in formsan1.txt) ... as far as i could see you preselect an option with no value ... so we could adapt the function then ... and have a look at the input-field ... i hide it initially ... now when you change the selected value we get the input shown in all cases except cartridge ...

kind regards
