show and hide popmenu

**arahmancsd** · 04-25-2010, 06:16 AM

Dear All,
I am new to this forum and new to asp.net and javascript
I am trying to create cross-browser popup menu in a click event of an html button as I have seen a good topic "popitupmenu" in
http://www.dynamicdrive.com/dynamicindex1/popit.htm

this link above add popupmenu in mouseHover of an <a> tag and I want to same popupmenu in click event of html button.

I changed <a> to a button <input type=button onclick="showmenu(event,linkset[1], '180px')">
but nothing has appeared, I debugged the code and found out that each time i click on html button the function hidemenu "Which hides the menu" is called.

I would really appreciate, how to show popupmenu in click event of html button and I click other at other places that popupmenu should dispear,

any ideas plz?
