If the new data is going to fit inside the existing info window without
changing its size, then you could put your content inside a <div> and
update that by id.
Caution: Opening the infowindow is asynchronous. In particular, the
first time you open the infowindow, there's a delay while the infowindow
code module is fetched, so you can't do this:
marker.openInfoWindowHtml('<div id="content"></div>');
document.getElementById("content").inerHTML = "initial text";
Also, you need to keep track of whether the user has closed the
infowindow. If it is closed call:
marker.openInfoWindowHtml('<div id="content">' + $("#new_text").val()
+ '</div>');
If it is open you can call
document.getElementById("content").inerHTML = $("#new_text").val();
I can't think of any easy way to check whether the data is going to fit
inside the existing infowindow.
