CakePHP: how to call javascript function in link?

Question

In html,

<a href="some_url"> Contact Seller </a> 

In CakePHP,

 <?php echo $this->Html->link('Contact Seller', array('controller'=>'pages', 'action'=>'contactseller', 'full_base'=>true)); ?> 

But I am having trouble converting the following html to Cakephp:

 <a href="some_url" onClick="return popup(this, 'popup_name')">my popup</a> 

The following is a popup javascript method:

 function popup(mylink, windowname) { if (! window.focus) return true; var href; if (typeof(mylink) == 'string') href=mylink; else href=mylink.href; window.open(href, windowname, 'width=400,height=200,scrollbars=yes'); return false; } 

How to convert html to cakephp?

 <a href="some_url" onClick="return popup(this, 'popup_name')">my popup</a> 

Thanks in advance.:)

Answer 1

 <a href="some_url" onClick="return popup(this, 'popup_name')">my popup</a> 

converts to this in CakePHP:

 $this->Html->link('my popup', 'some_url', ['onclick' => 'return popup(this, "popup_name")']); 

FYI. You can put any attribute in the third argument of the link () method. The documentation for creating links is quite extensive and provides examples.
