null error

crmpicco · March 30th, 2005, 07:36 AM

I have a form called 'fexp' and two hidden fields called 'multileg' and 'submitcounter', and they both have values of 'true' to start with. I have a Javascript function as per below:

Code:

function submitvalues()
{
if ((document.fexp.multileg.value == true)&&(document.fexp.submitcounter.value == true))
    {
        document.fexp.submit();
        document.fexp.multileg.value == false;
        document.fexp.submitcounter.value == false;
    }
}

I call it in the <body> tag:

Code:

<body bgcolor="#f5f5f5" leftmargin=0 topmargin=0 rightmargin=0 bottommargin=0 onload="setframe();document.fexp.depapt.focus();return submitvalues();">

But i keep get this error:

document.fexp.multileg.value is null or not a object.

However, it is DEFINATELY there:

Code:

<input type="hidden" name="multileg" value="<%=multileg%>">
                  <input type="hidden" name="submitcounter" value="<%=submitcounter%>">

Can you show the whole form, maybe you have two elements with the same name?
As a side issue:

Code:

if(document.fexp.multileg.value == true)

is not safe, the value property in this case is a string so:

Code:

if(document.fexp.multileg.value == "true")

The other debug test is to turn them, temporarily, into text elements and see if you can focus on them without submitting.

Code:

if(document.fexp.multileg.value == "true")

That was one of my problems, thank you.

This code changes the values of the txt boxes but it just keeps submitting the form continuously:

Code:

function submitvalues()
{
if ((document.fexp.multileg.value == "true")&&(document.fexp.submitcounter.value == "true"))
    {
        document.fexp.submit();
        document.fexp.multileg.value == "false";
        document.fexp.submitcounter.value == "false";
    }
}

how can i do it only once???

Well as both items need to be true before you submit set them to false immediately, otherwise the form submits before you change them:

Code:

if ((document.fexp.multileg.value == "true")&&(document.fexp.submitcounter.value == "true"))
    {
        document.fexp.multileg.value == "false";
        document.fexp.submitcounter.value == "false";
        document.fexp.submit();

    }

Seems odd that you need to do this at all. Why load a page and then submit immediately?

Code:

function submitvalues()
{
if ((document.fexp.multileg.value == "true")&&(document.fexp.submitcounter.value == "true"))
    {
        document.fexp.multileg.value == "false"
        document.fexp.submitcounter.value == "false"
        document.fexp.submit();
    }
}

That does the same, continuous submission of form.

Code:

<body bgcolor="#f5f5f5" leftmargin=0 topmargin=0 rightmargin=0 bottommargin=0 onload="setframe();submitvalues();">

Well you have to set to false on the server, modify "multileg" after you have submitted, then you can delete the two lines before the submission. As I said it's a weird way of doing something. What does the form do on the server when it's submitted?
