Hi

What's wrong with this code?

-- code start --
1 function pdf() {
2 flt = "source"+document.form1.elements["ReferencesSTD"].value;
3 if (document.all.flt1.innerText == "") {
4 document.all.pdf.innerText = "";
5 }
6 else {
7 document.all.pdf.innerText = &quot;<a href='&quot;+flt+&quot;' target='_new'><img src='images/pdf.gif' title='Click to see the standard in PDF!'></a>&quot;;
8 }
9 }
-- code end --

The variable flt eg. contains &quot;source3&quot;, but everytime i run the code it says error in line 3. &quot;Is null or not an object!&quot;

Can someone tell me what's wrong?

for starters, this
flt = &quot;source&quot;+document.form1.elements&quot;ReferencesSTD&quot;.value;

should be
flt = &quot;source&quot;+document.form1.elements[&quot;ReferencesSTD&quot;].value;

it might have just been the tgml though

Hi

I'll try again, there was some errors in the first code.

-- Code start --
1 function pdf() {
2 flt = &quot;source&quot;+document.form1.elements[&quot;ReferencesSTD&quot;].value;
3 if (document.all.flt.innerText == &quot;&quot;) {
4 document.all.pdf.innerText = &quot;&quot;;
5 }
6 else {
7 document.all.pdf.innerText = &quot;<a href='&quot;+flt+&quot;' target='_new'><img src='images/pdf.gif' title='Click to see the standard in PDF!'></a>&quot;;
8 }
9 }
-- Code end --

And now the form.

-- Code start --
10 <form name=&quot;form1&quot; method=&quot;post&quot; action=&quot;&quot;>
11 <select name=&quot;ReferencesSTD&quot; size=&quot;1&quot; id=&quot;ReferencesSTD&quot; class=&quot;dropdown&quot; onchange=&quot;pdf()&quot;>
12 <option value=0>- Please select -</option>
13 <option value=&quot;3&quot;>ISO9001</option>
14 <option value=&quot;4&quot;>ISO14001</option>
15 <option value=&quot;5&quot;>OHAS18001</option>
16 </select>
17 <span name=&quot;pdf&quot;></span> 
18 <input name=&quot;StandardComment&quot; type=&quot;text&quot; value=&quot;&quot; size=&quot;15&quot; maxlength=&quot;15&quot;></font>
19 <font color=&quot;#FFFFFF&quot;><span name=&quot;source3&quot;>upload\files\iso9001.pdf</span></font>
20 <font color=&quot;#FFFFFF&quot;><span name=&quot;source4&quot;></span></font>
21 <font color=&quot;#FFFFFF&quot;><span name=&quot;source5&quot;></span></font>
22 </form>
-- Code end --

ftl should be used to find some text in the span areas in the form. Eg. if flt = &quot;source3&quot; in line 2 it should take the text from source3.innerText (<span name=&quot;source3&quot;></span>) line 19 and put it into the pdf.innerText (<span name=&quot;pdf&quot;></span>) in line 17 contains the line &quot;upload\files\iso9001.pdf&quot;.

But the error occure in line 3.

I hope that you can see what i want to do, and can give me some help on how to do it right.

Peter,

This will fix most of the errors you are getting:

Code: 
<html>
<head>
<script type=&quot;text/javascript&quot;>
function pdf()
{
	var formObj = document.forms[&quot;form1&quot;];
	var flt = &quot;source&quot; + formObj.ReferencesSTD[formObj.ReferencesSTD.selectedIndex].value;
	if (document.getElementById(flt).innerText == &quot;&quot;) {
		document.getElementById('pdf').innerText = &quot;&quot;;
	} else {
		document.getElementById('pdf').innerText = &quot;<a href='&quot;+flt+&quot;' target='_new'><img src='images/pdf.gif' title='Click to see the standard in PDF!'></a>&quot;;
	}
}
</script>
</head>

<body>
<form name=&quot;form1&quot; method=&quot;post&quot; action=&quot;&quot;>
	<select name=&quot;ReferencesSTD&quot; size=&quot;1&quot; id=&quot;ReferencesSTD&quot; class=&quot;dropdown&quot; onchange=&quot;pdf()&quot;>
		<option value=0>- Please select -</option>
		<option value=&quot;3&quot;>ISO9001</option>
		<option value=&quot;4&quot;>ISO14001</option>
		<option value=&quot;5&quot;>OHAS18001</option>
	</select>
	<span id=&quot;pdf&quot;></span>
	<input name=&quot;StandardComment&quot; type=&quot;text&quot; value=&quot;&quot; size=&quot;15&quot; maxlength=&quot;15&quot;></font>
	<font color=&quot;#FFFFFF&quot;><span id=&quot;source3&quot;>upload\files\iso9001.pdf</span></font>
	<font color=&quot;#FFFFFF&quot;><span id=&quot;source4&quot;></span></font>
	<font color=&quot;#FFFFFF&quot;><span id=&quot;source5&quot;></span></font>
</form>
</body>
</html>

I'm still not 100% sure if the functionality is as you desire, but now the errors are gone, you should be able to rework it a bit more.

Hope this helps,

Dan

Hi Dan

Nothing changed!

I am still getting an error:

Error: Object doesn't support this property or method

The error occures in the line with:

if (document.getElementById(flt).innertext == &quot;&quot;) {

I hope you or anyone else can help me!

Peter,

That was weird - my post seemed to have some characters stripped out of it.

Try this:

Code: 
<html>
<head>
<script type=&quot;text/javascript&quot;>
function pdf()
{
    var formObj = document.forms [ &quot;form1 &quot; ];
	if (formObj.ReferencesSTD[formObj.ReferencesSTD.selectedIndex].value == 0) return;
	var flt = &quot;source&quot; + formObj.ReferencesSTD[formObj.ReferencesSTD.selectedIndex].value;

    if (document.getElementById(flt).innerText == &quot;&quot;) {
        document.getElementById('pdf').innerText = &quot;&quot;;
    } else {
        document.getElementById('pdf').innerText = &quot;<a href='&quot;+flt+&quot;' target='_new'><img src='images/pdf.gif' title='Click to see the standard in PDF!'></a>&quot;;
    }
}
</script>
</head>

<body>
<form name=&quot;form1&quot; method=&quot;post&quot; action=&quot;&quot;>
    <select name=&quot;ReferencesSTD&quot; size=&quot;1&quot; id=&quot;ReferencesSTD&quot; class=&quot;dropdown&quot; onchange=&quot;pdf()&quot;>
        <option value=0>- Please select -</option>
        <option value=&quot;3&quot;>ISO9001</option>
        <option value=&quot;4&quot;>ISO14001</option>
        <option value=&quot;5&quot;>OHAS18001</option>
    </select>
    <span id=&quot;pdf&quot;></span>
    <input name=&quot;StandardComment&quot; type=&quot;text&quot; value=&quot;&quot; size=&quot;15&quot; maxlength=&quot;15&quot;></font>
    <font color=&quot;#FFFFFF&quot;><span id=&quot;source3&quot;>upload\files\iso9001.pdf</span></font>
    <font color=&quot;#FFFFFF&quot;><span id=&quot;source4&quot;></span></font>
    <font color=&quot;#FFFFFF&quot;><span id=&quot;source5&quot;></span></font>
</form>
</body>
</html>

Hope this helps,

Dan
