How to call UDT onclick event?

[seregarem]

I need to call my User Defined Tag on button click event. How to do it?

You posted on wrong topic put I hope admins move this post correct topic.

Code: Select all

<button onclick="myFunction()">Click me</button>

<p id="demo"></p>
{literal}
<__script__>
function myFunction() {
    document.getElementById("demo").innerHTML = "{/literal}{root_page_id}{literal}";
}
</__script>

I tested it and its should work and next time do just some basic Googeling like "javascript onclick"!

btw. <__script__> is without __ forum add this

Your advice is not good to me. My UDT:

Code: Select all

$cid = (int)$params['cid'];
$db =& $this->GetDb();
$query = 'DELETE FROM cms_module_cgfeedback_comments WHERE id = ?';
$res = $db->Execute($query, array($cid));

Code: Select all

{literal}
<__script__>
function del(ans){
document.cookie = "a="+ans;
{/literal}
{del_ans cid=$smarty.cookies.a}
{literal}
document.getElementById('user_answer_'+ans).innerHTML = ans;
}
</__script>
{/literal}

So, UDT executes after loading a page, but not after click on a button... Param cid sets when an user click on button, but UDT executes after loading a page...

You can't a UDT is server side so a click event would have to make a call to the server either by loading another page or using Ajax,

yes, as applejack says, call new page using ajax, that works
