Hi monks,

I'm continuing to develop my website with Catalyst. I wrote a js snippet to modify html as below:

<form>
<table>
    <tbody><tr><td><button onclick="purchase_new('new_form')">new</spa
+n></button></td>
 </tbody></table>
</form>
<p id="new_form">

</p>

<script language="javascript">
function purchase_new(i){
var p_new = document.getElementById(i);

var new_table = document.createElement('table');
var new_th1   = document.createElement('th')
var new_th2   =    document.createElement('th');
var new_th3   = document.createElement('th');
var new_head1 = document.createTextNode('name');
var new_head2 = document.createTextNode('price');
var new_head3 = document.createTextNode('count');
var new_tr    = document.createElement('tr');
new_th1.appendChild(new_head1);
new_th2.appendChild(new_head2);
new_th3.appendChild(new_head3);


new_table.appendChild(new_th1);
new_table.appendChild(new_th2);
new_table.appendChild(new_th3);
new_table.appendChild(new_tr);
p_new.appendChild(new_table);
}

</script>

According to my predict, the page will add a new table when button clicked. But the fact is new table would flash and disappear quickly when I click button. I suspect form element result in it because it is all OK if I remove form element.

Any ideas? Thanks!

BTW, I noticed this article . And I'll apologize for my desert vocabulary if my post before made you or you uncomfortable. But I really really want to express my appreciation on the monks' help!
