Rjs not updating my page

hi,

I have this:

page.hide “transactionpopup”
page.replace_html
@shift.shifttype.name+"[email protected](’%d-%m-%Y’)
,calendarday(:shift=>@shift)
@exchangeproposals.each do |ep|
domid=ep.shift.shifttype.name+”
"+ep.shift.date.strftime(’%d-%m-%Y’)
page << “if $(’#{domid}’) {”
page.replace_html domid ,calendarday(:shift=>ep.shift)
page << “}”
end

the problem is with this part:

page << “if $(’#{domid}’) {”
page << “}”

when i use this, my script doesn’t work. , nothing happens and I am not
getting errors at all

I dont have a clue what the problem is.
when i check with firebug i see this response:

try {

Element.hide(“transactionpopup”);

Element.update(“Nacht_30-05-2008”, "\u003Cdiv
style=‘width:90%’\u003Ejos\u003Cbr\u003E\u003Cimg alt=

“Negotiate” border=“0” src="/images/negotiate.gif?1210763277"
/\u003E\u003C/div\u003E");

if $(‘Nacht_29-05-2008’) {

Element.update(“Vroeg_21-05-2008”, "\u003Cdiv style=‘width:100%;
height:100%;background:#d0e6f6’\u003Eremco

\u003C/div\u003E");

}

} catch (e) { alert(‘RJS error:\n\n’ + e.toString());
alert('Element.hide(“transactionpopup”);\nElement

.update(“Nacht_30-05-2008”, "\u003Cdiv
style=‘width:90%’\u003Ejos\u003Cbr\u003E\u003Cimg alt

=\“Negotiate\” border=\“0\”
src=\"/images/negotiate.gif?1210763277\" /\u003E\u003C/div

\u003E");\nif $(‘Nacht_29-05-2008’)
{\nElement.update(“Vroeg_21-05-2008”, "\u003Cdiv style='width

:100%;
height:100%;background:#d0e6f6’\u003Eremco\u003C/div\u003E");\n}’);
throw e }

That’s invalid syntax. It should be if( …) {

As an alternative to building fractured JS, check into using
page.select, which allows you to use css-style selectors to locate dom
elements. select can also be chained with methods like .any, .all,
etc so that you can iterate over the elements that you find. In this
case select(…).any(elem){elem.replace_html ‘blah’} would allow you
to replace the element if it exists. The advantage will be that the
intention of the code will be much clearer when you read it later.
