Remove item on an onclick event

IE7..
CRM 4.0..
Javascript..

I have an object with an onclick event that I want to remove. The onclick is set within existing CRM code. I want to replace it with my own event.

However, I have the assumed method..

crmForm.all["ts_addressesid"].detachEvent("onclick", openlui);  

..but this doesnt seem to do anything. One thing to note is that the function openlui is declared in an external file.

Any help is most appreciated!

the onclick is not visible in the html, i assume some wizardry has covertly attached the openlui function somehow...

Basically when i click the said image object, i get a crm lookup popup. That is what im trying to stop.

What are you trying to acheive for the end user? Would setting the the field to disabled or read-only not be an option instead? At least it would be "supported".
 

crmForm.all.ts_addressesid.disabled = true;

Open in new window

Incidentally, the reason the original code doesn't work (hadn't realised it was the built-in lookup function you were looking to disable) is because the function is not attached to the onclick event of the ts_addressesid object, rather it is attached to a SPAN tag within the control. Manipulating the DOM at that level is *not* the way to go ;)

I need to replace the event with my own... the image button is part of a crm lookup field, i need to retain the control but fire a different event when clicking the image.

I have sucessfully added my own event using:

crmForm.all["ts_addressesid"].attachEvent("onclick", test);

that works fine and fires the function "test".

However, after that, the other event fires.

i know its not CRM supported, but to be honest, most of the customisations we're having to do arent!... i cant find the said span... but i have found the CRM code that sets it..

taken from lookup.js in the CRM deployment
------------------------------------------
 
 
function BuildFieldSpan(lookupField, lookupItems)
{
var html = "";
var len = lookupItems.items.length;
for (var i = 0; i < len; ++i)
{
var item = lookupItems.items[i];
 
html += (i > 0 ? " " : "");
 
var e = parent.document.createElement("SPAN");
 
e.className	= "ms-crm-Lookup-Item";
e.oid		= item.id;
e.otype		= item.type;
e.innerHTML	= item.html;
e.onclick	= "openlui();";
 
html += e.outerHTML;
}
if (html.length == 0)
{
html = "&nbsp;";
}
return html;
}

Open in new window
