Question

I’m trying to submit a form upon changing of a text field in HTML. Currently, my code looks something like this:

echo("<form name=\"editAgendaItem" . $this->Id . "\" id=\"editAgendaItem" . $this->Id . "\" method=\"post\" action=\"./?module=meetings&preload=edit&function=editAgendaItem&agendaitem=" . $this->Id . "\">\n");
echo("<table width=\"100%\" border=0>\n");
echo("<tr><td width=\"20px\">" . $this->Index . "</td><td><input type=\"text\" value=\"" . $this->Title . "\" name=\"agendaItemTitle" . $this->Id . "\" onChange=\"javascript:document.forms['editAgendaItem" . $this->Id . "'].submit();\" />");
echo("</td>\n");
...

Which evaluates to

<form name="editAgendaItem19" id="editAgendaItem19" method="post" action="./?module=meetings&preload=edit&function=editAgendaItem&agendaitem=19">
<table width="100%" border=0>
<tr><td width="20px">1</td><td><input type="text" value="" name="agendaItemTitle19" onChange="javascript:document.forms['editAgendaItem19'].submit()" /></td>
...

But more importantly

<form name="editAgendaItem19" id="editAgendaItem19" method="post" action="...">
<input type="text" value="" name="agendaItemTitle19" onChange="javascript:document.forms['editAgendaItem19'].submit()" />
...

• Which is eventually terminated by a tag. My problem is that upon modifying the field and dropping focus, the form does not submit.

Thanks in advance for any help.

Edit:

I’ve also tried using this method in the onChange event instead of in-line code:

<script type="text/javascript">
function submitForm(FormName)
{
  document.forms[FormName].submit();
}
</script>

Edit:

Took the suggestion to use the following code:

<script>
$(document).ready(function(){
   $('#agendaItemTitle24').live('blur',function()
      $('#editAgendaItem24').submit();
   });
});​

</script>

In my head, and

<form name="editAgendaItem24" id="editAgendaItem24" method="post" action="...">
<input type="text" value="" name="agendaItemTitle24" id="agendaItemTitle24" />
</form>

In my content. Still no dice.

Your HTML could be like this:

<form name="myForm" id="myForm" method="post" action="...">
<input type="text" value="" name="myInput" id="myInput"/>  

Now use jQuery:

<script type="text/javascript">
$(document).ready(function(){
   $('#myInput').live('blur',function(){
      $('#myForm').submit();
   });
});​
</script>
