I have a Javascript file that finds the top-left coordinates of an
element (image) as follows:
function getTopLeftCoordinate() {
x=document.getElementById(''coordinate'').offsetLeft
y=document.getElementById(''coordinate'').offsetTop
alert (x)
alert (y)
}
And, on "show.html.erb", I have the following:
<p id="notice"><%= notice %></p>
<p>
<b> Name </b>
<%= @dicom.name %>
</p>
<p>
<b> Image </b>
</p>
<p>
<%= image_tag @dicom.photo.url , :id => ''coordinate''
%>
</p>
<%= javascript_include_tag "coordinate" %>
<%= link_to ''Edit'', edit_dicom_path(@dicom) %>
<%= link_to ''Back'', dicoms_path %>
As you know, if I want to run the Javascript code on loading the page, I
use <body onload="getTopLeftCoordinate()";>
How can I do that in my "show.html.erb" file? Since I don''t
have a body
tag?
Thanks.

I used Tim Parkin''s post here: http://www.ruby-forum.com/topic/146295 Based on his solution, I had to do the following for it to work. In "show.html.erb": <%= update_page_tag do |page| page << "getTopLeftCoordinate();" end %> Thanks. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You should use s javascript librery other wise it will take you ages to make something practical and even more time to make your code work on all browsers. javascript libreries lets you do thigns like client side validation, date picker, inline editing, autocomplete, slider, drag and drop, sorting tooltips, progress bar ajax. In other words make your site fell like a desktop application http://jqueryui.com/ http://mootools.net/ http://www.dojotoolkit.org/ On Mon, Sep 13, 2010 at 9:38 AM, Marnen Laibow-Koser <lists-fsXkhYbjdPsEEoCn2XhGlw@public.gmane.org>wrote:> Frederick Cheung wrote: > > On Sep 12, 11:48�pm, Abder-Rahman Ali <li...-fsXkhYbjdPsEEoCn2XhGlw@public.gmane.org> wrote: > > > >> As you know, if I want to run the Javascript code on loading the page, I > >> use <body onload="getTopLeftCoordinate()";> > >> > >> How can I do that in my "show.html.erb" file?
