getting form data

Hi,

I am trying to use this function to get the for data :

Expand|Select|Wrap|Line Numbers

 function getform(divid) { 

var getstr=''; 

var obj=document.getElementById(divid)? document.getElementById(divid) : document.forms[divid];

for (i=0; i<obj.childNodes.length; i++) { 

if (obj.childNodes[i].tagName == "INPUT") {

if (obj.childNodes[i].type == "text") {getstr +="&" + obj.childNodes[i].name + "=" + obj.childNodes[i].value;}

if (obj.childNodes[i].type == "hidden") {getstr +="&" + obj.childNodes[i].name + "=" + obj.childNodes[i].value;}

if (obj.childNodes[i].type == "password") {getstr +="&" + obj.childNodes[i].name + "=" + obj.childNodes[i].value;}

if (obj.childNodes[i].type == "checkbox") { if (obj.childNodes[i].checked) {getstr +="&" + obj.childNodes[i].name + "=" + obj.childNodes[i].value;} else { getstr +="&" + obj.childNodes[i].name + "=off"; }}

if (obj.childNodes[i].type == "radio") { if (obj.childNodes[i].checked) {getstr +="&" + obj.childNodes[i].name + "=" + obj.childNodes[i].value;}  else { getstr +="&" + obj.childNodes[i].name + "=off"; }}}   

if (obj.childNodes[i].tagName == "SELECT") {var sel = obj.childNodes[i]; getstr +="&" + sel.name + "=" + sel.options[sel.selectedIndex].value;}} 

 return getstr;}

where the id or the name of the form is sent to this function and values are returned.

it works ok,

but when my fields are in a table it doesn't work, it finds the "table" tag as the childnode instead of input or select.

how can i make this work with tables?

sure,

I have progressed it a little bit to get the childs, but it seems it is looping around the first <td><input> found.

let say this is the form :

[HTML]
<form id="form1" action="" method="post" onsubmit="return false;">
<table>
<tr>
<td>
<input type="text" name="var1" value="var1">
</td>
</tr>
<tr>
<td>
<input type="text" name="var2" value="var2">
</td>
</tr>
<tr>
<td>
<input type="submit" name="p6_Submit" value="submit" onclick="test('form1');"/>
</td>
<tr>
</table>
</form>
[/HTML]

using these functions, it loops round var1 and browser locks up because of this loop

here is the javascript code

Expand|Select|Wrap|Line Numbers

  
function test(form) {

var obj=document.getElementById(form)? document.getElementById(form) : document.forms[form]; 

alert(getform(obj));

}
 
function getform(obj) { 

var getstr='';

for (i=0; i<obj.childNodes.length; i++) { 

if (obj.childNodes[i].tagName == "INPUT") { 

if (obj.childNodes[i].type == "text") {getstr +="&" + obj.childNodes[i].name + "=" + obj.childNodes[i].value;} }   

if (obj.childNodes[i].childNodes.length > 0) {getstr+=getform(obj.childNodes[i]);}

} 

return getstr;

}

as you can see, I used this to loop the childes
[php]if (obj.childNodes[i].childNodes.length > 0) {getstr+=getform(obj.childNodes[i]);}[/php]

This should be a very common problem, I wonder why I couldn't find anything on it.

Here is a full code,
if anybody could make it work, i would really appreciate it.

I am expecting an alert of "&p6_fullname=test&p6_email=test"

[HTML]
<html>
<head>
<script type="text/javascript">
function test(form) {
var obj=document.getElementById(form)? document.getElementById(form) : document.forms[form];
alert(getform(obj));
}

function getform(obj) {
var getstr='';
for (i=0; i<obj.childNodes.length; i++) {
if (obj.childNodes[i].childNodes.length > 0) {getstr+=getform(obj.childNodes[i]);}
else if (obj.childNodes[i].tagName == "INPUT") {
if (obj.childNodes[i].type == "text") {getstr +="&" + obj.childNodes[i].name + "=" + obj.childNodes[i].value;} }
}
return getstr;
}
</script>
</head>
<body>
<form id="form1" onsubmit="return false;">
<table>
<tr>
<td>Full Name:</td>
<td><input type="text" name="p6_fullname" value="test" size="40" /></td>
</tr>
<tr>
<td>email:</td>
<td><input type="text" name="p6_email" value="test" size="40" /></td>
</tr>
<tr><td><input type="submit" name="p6_Submit" value="submit" onclick="test('form1');"/></td></tr>
</table>
</form>
</body>
</html>
[/HTML]
