            <input type="button" id="btnsubmit" onclick="doSubmitImg(eval([document.getElementById('titulo'),document.getElementById('contenido')]),document.getElementById('imagen'))" value="Agregar" />
            <input type="reset" value="Reestablecer" />
            <input type="hidden" name="codigo" id="codigo" />
        </p>
    </fieldset>
</form>
</body>
</html>

and here's the script:

Code:

// JScript File
function exists(val) {
if(!val||val==="undefined"||typeof(val)=="undefined") {
    return false;
}
return true;
}

function modChkboxState(active,other) {
    if(active.checked) {
        other.disabled="disabled";
        other.checked=null;
    } else {
        other.disabled=null;
    }
}

function doSubmit(validate) {
    var x
    for(x in validate) {
        if(!exists(validate[x].value)) {
            alert("debe especificar un "+validate[x].id);
            return;
        }
    }
    if(exists(document.getElementById("codigo"))) {
        document.getElementById("codigo").value=Date.now();
    }
    document.getElementById(frm).submit();
}

when selecting "destacado", "boletin" should disable itself and the other way around.
also I made a small script that validate's presence of text in "titulo" and "contenido". But all I get when testing on IE is an "object expected" Error.

plz help me

That works for me on I.E., but the only values that should be assigned to .disabled and .checked are true and false.

Only Mozilla has a Date::now method; use

Code:

new Date().getTime();

Also, you must lose type='application/javascript'; it isn't globally supported and will not be viable for years to come. It will cause an error in I.E. if not changed to type='text/javascript'.

if(!val||val==="undefined"||typeof(val)=="undefine d") {
return false;
}
return true;
}

What is this function supposed to do?

There is no need to use eval to handle those parameters, and if you call the submit method instead of using a submit button, the form cannot be sent if JS is disabled.

What is this function supposed to do? I am confused.
