With JavaScript, you'd use the disabled property. However, if you're going to set it whilst the page is loading with ASP, just include it within the tag:

<input type="text" <% if it should be disabled, just print out: disabled="true" %> ...>

Re. the validation, please provide more details.

u can used directly in page
like
[HTML]<input type='control- text/button etc' name='' id='' <%if rs("field")=1 then%>

hi ...

i'm not familiar with vb-script but in case you want to set the disabled-attribute dynamically then use something like this (javascript):

var input_node = document.getElementById('your_input_node_id');
 
// to disable the box
input_node.setAttribute('disabled', 'disabled');
 
// to make it readonly (text stays selectable)
input_node.setAttribute('readonly', 'readonly');
 
// to enable it simply remove the attributes
input_node.removeAttribute('disabled');
 
// or 
input_node.removeAttribute('readonly');
 

kind regards

hello
where i have to use it can you sugest any position of code .
code would write within javascript tag

[gits]

hi ...

you have to assign an eventhandler to your select-element and call a function:

[HTML]<select name="my_name" onchange="toggl e_state(this);" >[/HTML]
now in the head of your page define the script-node:

<script type="text/javascript">
    function toggle_state(obj) {
        // here we check the value of your select-box
        var val = obj.value == 'floppy_cd';
 
        var input_node = document.getElementById('your_input_node_id');
 
        if (val) {
            input_node.setAttribute('readonly', 'readonly');
        } else {
            input_node.removeAttribute('readonly');
        }
    }
</script>
 

kind regards

[gits]

you have to adapt the val-check to your option values of course.

are you sure that there are no changes? :) ... try to input something in case it should have been readonly ...

and please now tell clearly: should it be disabled, readonly or hidden?

kind regards

ps: please post your option html-code
