hey all

I am working with a javascript function called Elabel, part of the  
Google maps api  
the Elabel has a function called setContents(html)

i need to be able to call this function and get new html for it. ( the  
html is a table that displays weather data)

here is what i have so far

function replace\_weather\_table(){  
zoomy = map.getZoom();  
weather\_table\_one.setContents(new Ajax.Request(’/weather/  
update\_weather\_tables?zoom=’+zoomy));  
};

GEvent.addListener(map,“moveend”, replace\_weather\_table);

i would like to have the contents be those of a partial, but when  
executed, the display only shows “[object Object]”

would appreciate any help, thanks

sk

</div>

make a controller respond to ajax and return a .js.erb it will be  
evaluated  
dynamically.

</div>

load jquery first and perform a $.get([controller\_path], null,  
null,‘script’)

return a whatever.js.erb with a content like

$("#thingy").html("\<%=escape\_javascript(render :partial  
=\>“controller/whatever”)%\>");

I don’t understand your logic flow. Can you clarify?

Is the new HTML rendered by your Rails app, then, or does it come from a  
remote server?
