to initialize a javascript loaded grid, I need to pass a list of values

  • 0

to initialize a javascript loaded grid, I need to pass a list of values from controller/gsp. Since the javascript is activated once the page is rendered/loaded, there may not be a direct way to do it. 2 possibilities
1. do an ajax call, and retrieve the list of values from the server
2. store the list in html as a hidden element, and read it from javascript.

option 2 seems better as it avoids few calls back to server. So, which control should I use for a list of values? Any jQuery code snippet to read it back into array/list.

thanks in advance.

    It depends on the size of that data. It it’s small enough, you could embed it in the page. For example, to populate a calendar with events, I used something like:

    <div id="calendar" data-events="[/* event list */]"></div>

    (the data-events attribute contained a JavaScript array of event objects in JSON format)

    However, if you’re talking about a huge amount of data, loading it (possibly in chunks) asynchronously after the page load (or when the document is ready) could increase your app’s performace and make it more interactive (i.e. I don’t want to wait and load that data if the next thing I’m gonna do is navigate away)

    Does that answer your question?
